+INSTRUCTIONS:
+
+1 - Configure your subject router according to accept/router_benchmark/conf/router.toml")
+    If using openwrt, an easy way to do that is to install the bmtools.ipk package. In addition,
+    bmtools includes two microbenchmarks: scion-coremark and scion-mmbm. Those will run
+    automatically and the results will be used to improve the benchmark report.
+
+    Optional: If you did not install bmtools.ipk, install and run those microbenchmarks and make a
+    note of the results: (scion-coremark; scion-mmbm).
+
+2 - Configure the following interfaces on your router (The procedure depends on your router
+    UI) - All interfaces should have the mtu set to 9000:
+    - One physical interface with addresses: {", ".join(multiplexed)}
+{nl.join(['    - One physical interface with address: ' + s for s in exclusives])}
+
+    IMPORTANT: if you're using a partitioned network (eg. multiple switches or no switches),
+    the "must reach" annotation matters. The '#' number is the order in which the corresponding host
+    interface must be given on the command line in step 7.
+
+3 - Connect the corresponding ports into your test switch (best if dedicated for the test).
+
+4 - Restart the scion-router service.
+
+5 - Pick the same number of physical interfaces on the system where you are running this
+    script. Make sure that these interface aren't used for anything else and have no assigned
+    IP addresses. Make a note of their names and, if using a partitioned network, associate each
+    with one of the numbers from step 2.
+
+6 - Connect the corresponding ports into your test switch. If using a partitioned network, make
+    sure that port is reachable by the corresponding subject router port.
+
+7 - Execute this script with arguments: --run <interfaces>, where <interfaces> is the list
+    of names you collected in step 5. If using a partitioned network, make sure to supply them
+    in the order indicated in step 2.
+
+    If coremak and mmbm values are available, the report will include a performance index.
+
+    If coremark and mmbm are not available from the test subject, you may supply them on the command
+    line. To that end, add the following arguments: "--coremark=<coremark>", "--mmbm=<mmbm>", where
+    <coremark> and <mmbm> are the results you optionally collected in step 1.
+
+8 - Be patient...
+
+9 - Read the report.

+    """Evaluates the performance of an external router running the SCION reference implementation.
+
+    The performance is reported in terms of packets per available machine*second (i.e. one
+    accumulated second of all configured CPUs available to execute the router code).
+
+    The router can actually be anything that has compatible metrics scrapable by
+    prometheus. So that's presumably the reference implementation or a fork thereof.
+
+    This test runs against a single router. The outgoing packets are not observed, the incoming
+    packets are fed directly by the test driver (brload). The other routers in the topology are a
+    fiction, they exist only in the routers configuration.
+
+    The topology (./conf/topology.json) is the following:
+
+    AS2 (br2) ---+== (br1a) AS1 (br1b) ---- (br4) AS4
+                 |
+    AS3 (br3) ---+
+
+    Only br1a is executed and observed.
+
+    Pretend traffic is injected by brload's. See the test cases for details.
+
+    This class is a Mixin that borrows the following attributes from the host class:
+    * coremark: the coremark benchmark results.
+    * mmbm: the mmbm benchmark results.
+    * packet_size: the packet_size to use in the test cases.
+    * intf_map: the map "label->actual_interface" map to be passed to brload.
+    * brload: "localCmd" wraper for the brload executable (plumbum.machines.LocalCommand)
+    * brload_cpus: [int] cpus where it is acceptable to run brload ([] means any)
+    * artifacts: the data directory (passed to docker).
+    * prom_address: the address of the prometheus API a string in the form "host:port"

+// We're only executing and monitoring br1a. All the others are a fiction (except for the knowledge

+// To reduce maintainers headaches, the topology follows a convention to assign addresses, so that
+// an address can be derived from a minimal information:
+// * AS-1 is the hub of the test. Others are hereafter called children.
+// * All IPs are V4.
+// * Interface numbers are equal to the index of AS to which they connect.
+// * ISD/AS: <1 or 2>-ff00:0:<AS index>
+// * subnets are 10.123.<child AS number> except internal subnets that are 10.123.10*<AS>.<rtr>
+// * hosts are 10.123.s.<interface number>
+// * Mac addressed (when we can choose) derive from the IP
+// * Ports are always 50000 for external interfaces and 30042 for internal interfaces.
+//
+// Example:
+// * AS2 has only interface number 1 with IP 10.123.2.2 and mac address f0:0d:cafe:02:02 that
+//   connects to AS 1 interface number 2.
+// * AS1's interface number 2 has IP 10.123.2.1 and mac address f0:0d:cafe:02:01.
+// * AS1's 1st router interface 0 has IP 10.123.10.1 and mac address f0:0d:cafe:10:01.

-// router. The local dispatcher then anycasts between all local ports listening on that IP.

+# Test for Debian packages
+
+This is a minimal test for the debian packages built in dist/BUILD.bazel.
+
+## Run
+
+There are two ways to run this test:
+
+```sh
+# Build packages to bazel internal directory and run test
+bazel test --test_output=streamed //dist/test:deb_test
+```
+
+OR
+
+```sh
+# Build packages  .. or any other way to get the packages into deb/
+make dist-deb
+# Run the test script
+dist/test/deb_test.sh
+```
+
+## Scope
+
+The test should determine whether
+
+- the packages can be installed
+- the binaries in the packages are runnable
+- the systemd units in the packages can be used to interact with the SCION services
+
+The test does **not** attempt to simulate a working SCION network.
+The assumption is that if the services installed from the packages
+can be started (meaning they don't crash immediately after startup), the
+findings of the various acceptence and end-to-end integration tests apply.

-Setting up the development environment
-======================================
-
-Prerequisites
--------------
-
-#. Make sure that you are using a clean and recently updated **Ubuntu 18.04**.
-   Other Ubuntu versions (or systems) will usually be fine too, but some of the tooling may not work.
-   This environment assumes you're running as a non-root user with ``sudo`` access.
-#. Install ``docker``.
-   Please follow the instructions for `docker-ce <https://docs.docker.com/install/linux/docker-ce/ubuntu/>`_.
-   Then, add your user to the ``docker`` group:
-   ``sudo usermod -a -G docker ${LOGNAME}``, where ``${LOGNAME}`` is replaced with your user name. Log out
-   and log back in so that your membership of the ``docker`` group is seen by the shell session.
-
-   Optionally install ``docker-compose``. This is needed if you want to run the
-   ``docker-compose`` based test topology setup instead of the default setup based on ``supervisord``.
-   Please follow the instructions for `docker-compose <https://docs.docker.com/compose/install/>`_.
-
-Bazel & Co.
------------
-
-#. Clone the SCION repository into the appropriate directory inside your workspace. In the commands below,
-   replace ``${WORKSPACE}`` with the directory in which you want to set up the project:
-
-   .. code-block:: bash
-
-      cd ${WORKSPACE}
-      git clone https://github.com/scionproto/scion
-      cd scion
-
-#. We use `Bazel <https://bazel.build>`__ for both building and testing. To be
-   able to define the bazel version in the repository we use the `bazelisk
-   <https://github.com/bazelbuild/bazelisk>`__ wrapper around bazel. To set it
-   up simply use::
-
-      ./tools/install_bazel
-
-   and make sure that ``~/bin`` is on your ``PATH``.
-
-   You can also manually install ``bazelisk`` and create an alias so that
-   ``bazel`` will resolve to the ``bazelisk`` command.
-
-#. To install the required dependencies, run:
-
-   .. code-block:: bash
-
-      ./tools/install_deps
-
-#. Start the bazel-remote container.
-
-   We use `bazel-remote <https://github.com/buchgr/bazel-remote>`_ to cache
-   build artifacts from bazel. Bazel-remote can manage the disk space and does
-   not infinitely grow like the Bazel built-in disk-cache. To start bazel-remote run::
-
-      ./scion.sh bazel_remote
-
-#. Build SCION services and tools.
-
-   .. code-block:: bash
-
-      make
-
-#. Finally, check that tests run correctly:
-
-   .. code-block:: bash
-
-      make test
-      make test-integration
-
-#. (Optional) If you already have some code you wish to contribute upstream, you can also run the
-   linters locally with:
-
-   .. code-block:: bash
-
-      make lint
-
-
-Alternative: go build
----------------------
-
-Alternatively to building with bazel, the SCION services and tools can be built
-with ``go build``.
-Please be aware that **this is not the recommended setup for development**.
-Not all checks and linters can be run in this setup. Without running all checks
-locally, it is likely that there will be frustrating cycles with the CI system
-rejecting your changes.
-
-#. Determine the go version used in the bazel setup; the ``WORKSPACE`` file
-   specifies this version in the ``go_register_toolchains`` clause.
-
-   .. literalinclude:: ../../WORKSPACE
-      :start-at: go_register_toolchains(
-      :end-at: )
-      :emphasize-lines: 3
-
-   Building with newer go versions *usually* works.
-
-#. Install go. Either follow `the official instructions <https://go.dev/doc/install>`_
-   or check the `Ubuntu specific installation options on the golang wiki <https://github.com/golang/go/wiki/Ubuntu>`_.
-
-#. Build SCION services and tools.
-
-   .. code-block:: bash
-
-      go build -o bin ./<service>/cmd/<service>...
-
-
-Running SCION locally
----------------------
-
-#. SCION networks are composed of many different applications. To simplify testing, we provide a
-   tool that generates test topologies. To generate the files required by the default topology (see
-   ``doc/fig/default_topo.png`` for a diagram of this topology), run:
-
-   .. code-block:: bash
-
-      ./scion.sh topology
-
-   The above command creates the ``gen`` directory, which contains configuration files and cryptographic
-   material for multiple SCION ASes and ISDs.
-
-   .. Attention:: The certificates created by this command expire after 3 days if the
-      infrastructure is not running for automatic renewal.
-
-#. To start the infrastructure we just generated, run:
-
-   .. code-block:: bash
-
-      ./scion.sh run
-
-#. To verify that your topology is running correctly, you can run an end to end reachability test using:
-
-   .. code-block:: bash
-
-      ./bin/end2end_integration
-
-#. This local infrastructure runs multiple SCION daemons, one in each AS.
-   We need to specify which instance is used when running end-host applications
-   that rely on the SCION daemon, e.g. to query paths.
-
-   The ``scion.sh topology`` script writes a file ``gen/sciond_address.json``,
-   mapping AS numbers to SCION daemon instance addresses. Either consult this
-   file manually, or use the ``scion.sh sciond-addr`` command:
-
-   .. code-block:: bash
-
-      # show paths from 1-ff00:0:112 to 1-ff00:0:110
-      ./bin/scion showpaths --sciond $(./scion.sh sciond-addr 112) 1-ff00:0:110
-
-
-#. To stop the infrastructure, run:
-
-   .. code-block:: bash
-
-      ./scion.sh stop
-
-
-Wireshark
----------
-
-To inspect SCION packets that are sent over the wire it can be helpful to use
-Wireshark. We use version 3.x of Wireshark, which is not shipped by default on
-Ubuntu 18.04. To install it use:
-
-.. code-block:: bash
-
-   sudo add-apt-repository ppa:wireshark-dev/stable
-   sudo apt-get update
-   sudo apt-get install wireshark
-
-To use the SCION dissector you need to install it:
-
-.. code-block:: bash
-
-   mkdir -p ~/.wireshark/plugins
-   cp tools/wireshark/scion.lua ~/.wireshark/plugins
-
-After that you can test it by running a topology and using a SCION filter for
-example::
-
-    tshark -Y 'scion.dst_as == "ff00:0:110"'
-
-
-Work remotely with Wireshark
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Sometimes it can be handy to use the remote feature of wireshark to tap into an
-interface on a different machine.
-
-
-#. Install wireshark on your local OS.
-
-   - For Ubuntu install as described in the steps above.
-   - For MacOS and Windows just download & install from the `wireshark website
-     <https://www.wireshark.org/#download>`_.
-
-
-#. Install dissector plugin
-
-   To install the dissector lua plugin copy it in the plugin folder of wireshark:
-
-   - Ubuntu:   same as in the previous step
-   - Windows:  ``%APPDATA%\Wireshark\plugins``
-   - MacOS:    ``/Applications/Wireshark.app/Contents/PlugIns/wireshark``
-
-   .. note::
-      The folder needs to be created if it doesn't exist.
-      (for more details visit `wireshark website: Plugin folders
-      <https://www.wireshark.org/docs/wsug_html_chunked/ChPluginFolders.html>`_)
-
-#. Prepare the remote machine
-
-   Install tcpdump::
-
-      sudo apt-get install tcpdump
-
-   The user used to SSH into the remote machine needs to have full access to tcpdump.
-   Hence create a new group and add this user to the group. SSH into the remote machine
-   and execute::
-
-      sudo groupadd pcap
-      sudo usermod -a -G pcap $USER
-
-   set this group as the owner of tcpdump::
-
-      sudo chgrp pcap /usr/sbin/tcpdump
-      sudo chmod 750 /usr/sbin/tcpdump
-
-   give tcpdump the necessary permissions::
-
-      sudo setcap cap_net_raw,cap_net_admin=eip /usr/sbin/tcpdump
-
-   .. note::
-      This will allow every user part of the pcap group to use the full
-      capabilities of tcpdump!
-
-#. Figure out the network interface on the remote host you want to tap into:
-   Get an IP address used by the SCION topology that's probably running with docker.
-   Search for the network-interface that's with the corresponding subnet.
-
-#. Start wireshark and click on the gear next to the interface named
-   "SSH remote capture: sshdump"
-   Fill in the IP address and Port of the remote host, as well as your preferred
-   authentication method in the Authentication tab.
-   At the Capture tab write the name of the interface you found in the previous
-   step. Find the a screenshot of an example below:
-
-   .. image:: wireshark.png
-
-#. Now you are ready to click start and investigate some SCION traffic

+Run the step-kms-plugin
+
+Synopsis
+~~~~~~~~
+
+
+This command leverages the step-kms-plugin to interact with cloud Key Management
+Systems (KMS) and Hardware Security Modules (HSM).
+
+The commands are passed directly to the step-kms-plugin. For more information on
+the available commands and their usage, please refer to the step-kms-plugin
+documentation at https://github.com/smallstep/step-kms-plugin. In order to enable
+KMS support, the step-kms-plugin must be installed and available in the PATH.
+
+Various commands of the scion-pki tool allow the use of KMS. In all cases, the
+private key needs to already exist in the KMS. To instruct the scion-pki tool to
+use the key in the KMS, the --kms flag must be set.
+
+For more information about supported KMSs and uri pattern, please consult
+https://smallstep.com/docs/step-ca/cryptographic-protection.

-
-.. note:: Note for Anapayans
-
-   This section contains general rules about how to contribute to the
-   open-source SCION project. If you are an Anapaya employee, some additional
-   rules may apply. Please see the internal Contribution Guide for more
-   information.
-
-What skills do you need to contribute?
-======================================
-
-SCION is a complex project, and uses a lot of different technologies. If you are unfamiliar
-with some of them, we have compiled a list containing some great resources to get you started.
-
-+----------------+----------------------------+------------------------------------------+
-|     Language   |    Contribution area       |    Tutorials                             |
-+----------------+----------------------------+------------------------------------------+
-|       Go       |   SCION Control-plane      |    :ref:`resources-for-learning-go`      |
-|                |   SCION Data-plane         |                                          |
-|                |   SCION Tools              |                                          |

-+----------------+----------------------------+------------------------------------------+
-|  Starlark      |   Bazel build/test system  | Coming soon                              |
-+----------------+----------------------------+------------------------------------------+
-
-Contributing to the Python and Starlark code bases is a bit trickier, so if you're just now
-starting out, we recommend going for Go first.
-
-You might also see some Bash and Makefile code in the code base. While this code changes from
-time to time, we strongly discourage contributions to these areas. Code in these languages also
-has a high chance of getting deleted completely in a refactoring pass.
-
-For version control, we use Git and GitHub. For more information about using Git (including
-links to resources to get you started if you've never used before), please visit :ref:`how-to-use-git-and-github`.
-
-No matter what language you want to contribute to, one of the first steps to take is to set
-up a development environment. See :ref:`setting-up-the-development-environment` for the needed steps.
-If you encounter issues, please visit our :ref:`Slack <slack>` and ask for help.
-
-Finding an issue to contribute to
-=================================
-
-We use GitHub labels to categorize issues in the SCION tracker. The two most interesting categories
-when searching for something to contribute to are:
-
-- `Help wanted issues <https://github.com/scionproto/scion/labels/i%2Fhelp%20wanted>`__.
-  These are issues that nobody is working on at the moment, and are up for grabs.
-- `Good first issue issues <https://github.com/scionproto/scion/labels/i%2Fgood%20first%20issue>`__.
-  These are usually **Help wanted** uses that are somewhat simpler. These are a good place to start if you've
-  never contributed to the project before.
-
-Once you find something you like, post a comment on the issue announcing that
-you're interested in working on it. This initial message signals to others that
-somebody is already working on it (and thus avoids duplicate work), and also is
-the first step in gathering more information about the issue from the SCION team.
-
-From this point on, somebody from the SCION maintainers team will reach out to
-you and guide you for the rest of the process. If you have any questions, please
-remember to shoot us a question on our :ref:`Slack <slack>`.
-
-Finally, make sure that the code you write adheres to the SCION project
-:ref:`language-style-guides`.
-
-Change Proposal Process
-=======================
-
-Many changes, including bug fixes and documentation improvements, can be
-implemented and reviewed via the normal GitHub pull request workflow.
-
-More **substantial changes** must be submitted as a **proposal**
-in the form of a GitHub issue, in order to create a consensus among the SCION community.
-Typical examples for substantial change proposals include:
-
-* Adding, changing, or removing compontents or functionality
-* Changing interfaces between components
-
-Proposals for changes to the SCION protocol (e.g., header format, processing
-rules, cryptography) are currently following the same process. This may,
-however, change in the near future when a formal specification or standard for
-the SCION protocol is established.
-
-.. hint:: It is recommended to discuss proposals with other (senior) developers
-   before submitting them, for example on our :ref:`Slack <slack>`.
-
-.. warning:: Pull requests for substantial features that did not go through the
-   proposal process will be rejected or put on hold.
-
-Formal Process
---------------
-
-.. image:: fig/change-proposal-process.excalidraw.png
-
-:Creation: To open a proposal, the author submits a GitHub issue following the
-  proposal template.
-:Review: The proposal may receive feedback from the community, which should be
-  incorporated by the author. Moreover, the assigned technical team triages the
-  proposal and assigns one of its members to manage the process. The technical
-  team discusses the proposal and provides feedback. To increase transparency,
-  the results of these discussions are summarised publicly.
-:Decision:
-  The technical team decides to **accept**, **postpone**, or **reject** the
-  proposal based on the outcomes of the discussion and feedback from the
-  community.
-:Design:
-  If the proposal has been accepted, the authors submit a design document and
-  submit it to the repository (`doc/ <https://github.com/scionproto/scion/tree/master/doc>`__)
-  in the form of a pull request.
-:Final review:
-  The design document will be reviewed by the assigned technical team. Since
-  all major points should already be agreed upon in the proposal review, this
-  final review is expected to be lightweight. After this review, the technical
-  team may start the final comment period, together with a proposition to
-  **merge**, **close**, or **postpone** the proposal.
-
-  The **final comment period** lasts **ten calendar days** and is advertised, such that
-  stakeholders have a chance to lodge any final objections before a decision is
-  reached. If no major comments are raised during the final comment period, the
-  proposed action (close, merge, or postpone) is accepted; otherwise, the
-  proposal goes back to the review step and is discussed further.
-:Implementation:
-  If the final comment period ends with the decision to merge the proposal, it
-  becomes active. The proposal can now be implemented (typically, but not
-  necessarily by the authors). The implementation is submitted as a pull
-  request. The implementation will be reviewed; acceptance of the proposal does
-  not automatically imply that its implementation will be accepted.

+
+
+Introduction
+============
+
+The SCION control plane is responsible for discovering path segments and making them available to
+endpoints. This includes path-segment exploration (also called "beaconing"), registration, lookup,
+and finally the combination of path-segments to end-to-end paths.
+
+.. Note: content based on (extracts from) IETF draft draft-dekater-scion-controlplane-00.
+
+The **control service** is responsible for the path exploration and registration processes in the
+control plane.
+It is the main control-plane infrastructure component within each SCION :term:`AS`.
+The control service of an AS has the following tasks:
+
+- Generating, receiving, and propagating :term:`Path Construction Beacons (PCBs) <PCB>`.
+  Periodically, the control service of a core AS generates a set of PCBs, which are forwarded to the
+  child ASes or neighboring core ASes.
+  In the latter case, the PCBs are sent over policy-compliant paths to discover multiple paths
+  between any pair of core ASes.
+- Selecting and registering the set of path segments via which the AS wants to be reached.
+- Managing certificates and keys to secure inter-AS communication.
+  Each PCB contains signatures of all on-path ASes.
+  Every time the control service of an AS receives a PCB, it validates the PCB's authenticity.
+  When the control service lacks an intermediate certificate, it can query the control service of
+  the neighboring AS that sent the PCB.
+
+Path Segments
+-------------
+
+As described previously, the main goal of SCION's control plane is to create and manage path
+segments, which can then be combined into forwarding paths to transmit packets in the data plane.
+SCION distinguishes the following types of path segments:
+
+- A path segment from a non-core AS to a core AS is an *up-segment*.
+- A path segment from a core AS to a non-core AS is a *down-segment*.
+- A path segment between core ASes is a *core-segment*.
+
+So each path segment either ends at a core AS, or starts at a core AS, or both.
+
+.. note::
+
+   There are no SCION path segments that start and end at a non-core AS. However, when combining
+   path segments into an end-to-end SCION path, shortcuts and peering-links can be used.
+
+All path segments are reversible: A core-segment can be used bidirectionally, and an up-segment can
+be converted into a down-segment, or vice versa, depending on the direction of the end-to-end path.
+This means that all path segments can be used to send data traffic in both directions.
+
+.. _control-plane-beaconing:
+
+Path Exploration (Beaconing)
+============================
+
+**Path exploration** is the process where an AS discovers paths to other ASes. In SCION, this
+process is referred to as *beaconing*.
+
+In SCION, the *control service* of each AS is responsible for the beaconing process.
+The control service generates, receives, and propagates *path-segment construction beacons (PCBs)*
+on a regular basis, to iteratively construct path segments.
+PCBs contain topology and authentication information, and can also include additional metadata that
+helps with path management and selection.
+The beaconing process itself is divided into routing processes on two levels, where *inter-ISD* or
+core beaconing is based on the (selective) sending of PCBs without a defined direction, and
+*intra-ISD* beaconing on top-to-bottom propagation.
+This division of routing levels is a key architectural decision of SCION and important for achieving
+a better scalability.
+
+- *Inter-ISD or core beaconing* is the process of constructing path segments between core ASes in
+  the same or in different ISDs. During core beaconing, the control service of a core AS either
+  initiates PCBs or propagates PCBs received from neighboring core ASes to other neighboring core
+  ASes. Core beaconing is periodic; PCBs are sent over policy-compliant paths to discover multiple
+  paths between any pair of core ASes.
+- *Intra-ISD beaconing* creates path segments from core ASes to non-core ASes. For this, the control
+  service of a core AS creates PCBs and sends them to the non-core child ASes (typically customer
+  ASes). The control service of a non-core child AS receives these PCBs and forwards them to its
+  child ASes, and so on. This procedure continues until the PCB reaches an AS without any customer
+  (leaf AS). As a result, all ASes within an ISD receive path segments to reach the core ASes of
+  their ISD.
+
+On its way, a PCB accumulates cryptographically protected path- and forwarding information per
+traversed AS. At every AS, metadata as well as information about the AS's ingress and egress
+interfaces are added to the PCB.
+
+Origination of PCBs
+-------------------
+
+Every core AS originates PCBs at regular intervals, and sends these to all egress interfaces to
+connected neighbor ASes.
+An originated PCB sent to a neighboring core ASes initiates an inter-ISD beacon, ultimately
+resulting in a core-segment.
+An originated PCB sent to a child AS initiates the intra-ISD beacon creating an up/down segment.
+
+Propagation of PCBs
+-------------------
+
+PCBs are propagated at regular intervals at each AS.
+When PCBs are received, they are not propagated immediately, but put into temporary storage
+until the next propagation event.
+The selection and propagation of PCBs differs between the inter-ISD and intra-ISD beacon schemes.
+
+Core ASes implement the inter-ISD / core beaconing scheme.
+For every interface connecting to a neighboring core AS:
+
+1. Select the best :math:`N` PCBs for each origin core AS.
+   This can take into account both the available PCBs as well as local policies and information
+   about the link to the neighbor.
+2. Extend the selected PCBs by adding an *AS entry*
+3. Send the extended PCBs over the interface
+
+Non-core ASes implement the intra-ISD / non-core beaconing scheme.
+For every interface connecting to a child AS:
+
+1. Select the best :math:`N` PCBs.
+   This can take into account both the available PCBs as well as local policies and information
+   about the link to the child AS.
+2. Extend the selected PCBs by adding an *AS entry*
+3. Send the extended PCBs over the interface
+
+AS Entries
+----------
+
+Every AS adds a signed *AS entry* to the PCBs it originates, propagates or :ref:`registers <control-plane-registration>`.
+
+This AS entry includes the relevant network topology information for this AS-hop
+defined by the ingress and egress :term:`interface IDs <Interface ID>` of the beacon.
+The so-called *hop field* includes a MAC that authorizes the use of this hop in the path
+segment defined by the PCB, until it expires.
+See the description of the :ref:`SCION Path <path-type-scion>` in the data plane section for more
+details on the hop field format and the MAC chaining mechanism.
+
+Additionally, an AS entry can contain :doc:`metadata <beacon-metadata>` such as the link MTU,
+geographic locations of the AS routers, latencies, etc.
+
+For illustration, the following code blocks show the definition of the protobuf message definitions
+for the AS entry "body" and the contained hop field information.
+This is just a small excerpt of the relevant definitions.
+See the `SCION Control Plane IETF draft (section "Components of a PCB") <https://www.ietf.org/archive/id/draft-dekater-scion-controlplane-00.html#name-components-of-a-pcb-in-mess>`_

+Peering Links
+-------------
+
+PCBs do not traverse peering links.
+Instead, available peering links are announced along with a regular path in the individual AS
+entries of PCBs.
+If both ASes at either end of a peering link have registered path segments that include a specific
+peering link, then it can be used to during segment combination to create an end-to-end path.
+
+.. _control-plane-registration:
+
+Registration of Path Segments
+=============================
+
+**Path registration** is the process where an AS transforms selected PCBs into path segments,
+"terminating" them by adding a final AS entry with a zero egress interface,
+and adds these segments to the relevant path databases, thus making them available for the path
+lookup process.
+
+As mentioned previously, a non-core AS typically receives several PCBs representing path segments to
+the core ASes of the ISD the AS belongs to.
+Out of these PCBs, the non-core AS selects those down-path segments through which it wants to be
+reached, based on AS-specific selection criteria.
+The next step is to register the selected down-segments with the control service of the
+core AS that originated the PCB.
+
+Intra-ISD Path-Segment Registration
+-----------------------------------
+
+Every *registration period* (determined by each AS), the AS's control service selects of
+PCBs to transform into path segments:
+
+- Up-segments, which allow the infrastructure entities and endpoints in this AS to communicate with
+  core ASes.
+  Up-segments are registered in the local path database of the AS.
+- Down-segments, which allow remote entities to reach this AS.
+  Down-segments are registered, via a remote-procedure call, in the path-segment database of the
+  core AS that originated the PCB.
+  As a result, a core AS's path database contains all down-segments registered by their
+  direct or indirect customer ASes.
+
+Core Path-Segment Registration
+------------------------------
+
+The core beaconing process creates PCBs from core AS to core AS.
+Every *registration period*, the AS's control service selects sets of PCBs to turn into path
+segments and register.
+These selected core-segments are added to the local path database of the core AS that created the
+segment (i.e. the one at the end of the beacon chain), so that local and remote endpoints can obtain
+and use these core-segments.
+In contrast to the down-segment registration procedure, there is no need to register core-segments
+with other core ASes (as each core AS will receive PCBs originated from every other core AS).
+
+Path Lookup
+===========
+
+An endpoint (source) that wants to start communication with another endpoint (destination), needs
+up to three path segments:
+
+- An up-path segment to reach the core of the source ISD
+- a core-path segment to reach
+
+  - another core AS in the source ISD, in case the destination AS is in the same source ISD, or
+  - a core AS in a remote ISD, if the destination AS is in another ISD, and
+
+- a down-path segment to reach the destination AS.
+
+The process to look up and fetch path segments consists of the following steps:
+
+1. First, the source endpoint queries the control service in its own AS (i.e., the source AS) for
+   the required segments.
+   The control service has up-path segments stored in its path database.
+2. The control service in the source AS queries the control services of the reachable core ASes in
+   the source ISD, for core-path segments to core ASes in the destination ISD (which is either the
+   local or a remote ISD).
+   To reach the core control services, the control service of the source AS uses the locally stored
+   up-path segments.
+3. The control service then queries the control services of the remote core ASes in the destination
+   ISD, to fetch down-path segments to the destination AS.
+   To reach the remote core ASes, the control service of the source AS uses the previously obtained
+   and combined up- and core segments.
+4. Finally, the control service of the source AS returns all retrieved path segments to the source
+   endpoint.
+5. The endpoint combines all path segments into an end-to-end path
+
+All remote path-segment lookups by the control service are cached.
+
+On SCION end hosts, a :doc:`SCION daemon <manuals/daemon>` is usually employed to do the
+path-lookup on behalf of applications. This SCION daemon also caches path-segment lookup results.

+   ============ ===========================
+
+.. _control-plane-segment-combination:
+
+Path-Segment Combination
+========================
+
+The last step of the path-resolution process is to combine the available up, core and down
+path segments to end-to-end forwarding paths.
+This path-segment combination process is done by each endpoint separately.
+Typically, end hosts run the :doc:`SCION daemon <manuals/daemon>` which centralizes the
+path-resolution process and returns fully formed end-to-end paths to applications.
+However, applications could also choose to bypass the daemon and perform the path-resolution
+directly.
+
+The figures below illustrate the various ways in which segments can be combined
+to form end-to-end paths.
+See the description of the :ref:`SCION Path<path-type-scion>` for the specifics on how these
+end-to-end paths are encoded in the packet header.

+********
+Building
+********
+
+Building with go build
+======================
+
+SCION can be built with ``go build`` without any other system prerequisites.
+
+Please be aware that go build **is not the recommended setup for development** on SCION.
+Not all tests and checks can be run in this setup. We use Bazel to orchestrate all of this.
+Without running all checks locally, it is likely that there will be frustrating cycles with the CI
+system rejecting your changes.
+See :doc:`setup` for instructions on how to set up Bazel and the full development environment.
+
+Prerequisites
+-------------
+
+#. Clone the SCION repository into your workspace.
+
+   .. code-block:: bash
+
+      git clone https://github.com/scionproto/scion
+      cd scion
+
+#. Determine the go version used in the Bazel setup; the ``WORKSPACE`` file
+   specifies this version in the ``go_register_toolchains`` clause.
+
+   .. literalinclude:: /../WORKSPACE
+      :start-at: go_register_toolchains(
+      :end-at: )
+      :emphasize-lines: 3
+
+   Building with newer go versions *usually* works.
+
+#. Install go. Either follow `the official instructions <https://go.dev/doc/install>`_
+   or check the `Ubuntu specific installation options on the golang wiki <https://github.com/golang/go/wiki/Ubuntu>`_.
+
+Build
+-----
+
+* **Build only "distributables"**, without development and testing tools
+
+   .. code-block:: bash
+
+      CGO_ENABLED=0 go build -o bin/ ./{router,control,dispatcher,daemon,scion,scion-pki,gateway}/cmd/...
+
+* **Build all**
+
+   .. code-block:: bash
+
+      go build -o bin/ ./...
+
+Options
+-------
+
+* sqlite implementations: two different sqlite implementations can be chosen at build time:
+
+  - `modernc/sqlite <https://pkg.go.dev/modernc.org/sqlite>`_: **default**. A pure go implementation of sqlite (transpiled from C).
+  - `mattn/go-sqlite3 <https://github.com/mattn/go-sqlite3>`_: A CGO wrapper for the official sqlite implementation.
+    It is well established but requires CGO; this makes it impossible to build static binaries and
+    executables are dependent on a minimum glibc version.
+
+  Specify build tag (``go build -tags=<...>``) either ``sqlite_modernc`` or ``sqlite_mattn``.
+
+Building with Bazel
+===================
+
+Please be aware that the following instructions only result in a minimal build
+environment. Not all tests and checks can be run in this setup.
+See :doc:`setup` for instructions on how to set up Bazel and the full development environment.
+
+Prerequisites
+-------------
+
+#. Clone the SCION repository into your workspace.
+
+   .. code-block:: bash
+
+      git clone https://github.com/scionproto/scion
+      cd scion
+
+#. Install Bazel: either follow the official instructions at `<https://bazel.build/install>`_, or
+   run our helper script:
+
+   .. code-block::
+
+      tools/install_bazel
+
+#. Remove remote cache options from ``.bazelrc``; the default setup is useful to limit Bazel's
+   cache size when contributing to SCION, but requires a running docker container acting as the
+   "remote" cache service
+
+   .. code-block::
+
+      sed -e '/--remote_cache=/d' -i .bazelrc
+
+   Alternatively, if you have docker installed, you can run ``./scion.sh bazel-remote`` to start
+   the cache service.
+
+Build
+-----
+
+* **Build only "distributables"**, without development and testing tools
+
+   .. code-block:: sh
+
+      make build                          # or, ...

+      bazel build //:scion //:scion-ci
+
+* **Build packages for debian (all target architectures)**
+
+  .. code-block:: sh
+
+     make dist-deb                        # or, ...

+  .. code-block:: sh
+
+     make dist-openwrt                        # or, ...
+     bazel build //dist:openwrt_all
+

+
+For version control, we use Git and GitHub. For more information about using Git (including
+links to resources to get you started if you've never used before), please visit :doc:`git`.
+
+No matter what language you want to contribute to, one of the first steps to take is to set
+up a development environment. See :ref:`setting-up-the-development-environment` for the needed steps.
+If you encounter issues, please visit our :ref:`Slack <slack>` and ask for help.
+
+.. _finding-an-issue-to-contribute-to:
+
+Finding an issue to contribute to
+=================================
+
+We use GitHub labels to categorize issues in the SCION tracker. The two most interesting categories
+when searching for something to contribute to are:
+
+- `Help wanted issues <https://github.com/scionproto/scion/labels/i%2Fhelp%20wanted>`__.
+  These are issues that nobody is working on at the moment, and are up for grabs.
+- `Good first issue issues <https://github.com/scionproto/scion/labels/i%2Fgood%20first%20issue>`__.
+  These are usually **Help wanted** uses that are somewhat simpler. These are a good place to start if you've
+  never contributed to the project before.
+
+Once you find something you like, post a comment on the issue announcing that
+you're interested in working on it. This initial message signals to others that
+somebody is already working on it (and thus avoids duplicate work), and also is
+the first step in gathering more information about the issue from the SCION team.
+
+From this point on, somebody from the SCION maintainers team will reach out to
+you and guide you for the rest of the process. If you have any questions, please
+remember to shoot us a question on our :ref:`Slack <slack>`.
+
+Finally, make sure that the code you write adheres to the SCION project
+:doc:`style/index`.

+.. rubric:: Responsibilities and Tasks
+
+The TC Implementation has the following main responsibilities, as defined in its
+`charter <https://www.scion.org/assets/docs/SCION-Association-Charter-TC-Implementation.pdf>`_:
+
+* Coordination with the Association Board and other bodies of the SCION
+  Association. In particular, coordinate with the TC Standardisation to
+  synchronise the evolution of the SCION standards, specifications, and their
+  implementation. Consult with the Advisory Board on strategic planning.
+* Steering strategic direction of the open source SCION project(s); planning
+  projects aligned with priorities of SCION Association members and the open
+  source developer community.
+* Deciding on cross-cutting issues such as development processes, guidelines,
+  tooling, etc.
+
+The TC may define technical teams and work groups and delegate tasks.
+No technical teams or work groups are currently defined.
+
+Where not delegated to technical teams, the TC Implementation members
+participate in the day-to-day operations to implement the
+:ref:`change-proposal-process` defined below, in particular by
+
+* Participating in change proposal discussions and moderating discussions
+* Reviewing and deciding over individual change proposals and pull requests
+
+.. _change-proposal-process:
+
+Change Proposal Process
+=======================
+
+Many changes, including bug fixes and documentation improvements, can be
+implemented and reviewed via the normal GitHub pull request workflow.
+
+More **substantial changes** must be submitted as a **proposal**
+in the form of a GitHub issue, in order to create a consensus among the SCION community.
+Typical examples for substantial change proposals include:
+
+* Adding, changing, or removing components or functionality
+* Changing interfaces between components
+
+Proposals for changes to the SCION protocol (e.g., header format, processing
+rules, cryptography) are currently following the same process. This may,
+however, change in the near future when a formal specification or standard for
+the SCION protocol is established.
+
+.. hint:: It is recommended to discuss proposals with other (senior) developers
+   before submitting them, for example on our :ref:`Slack <slack>`.
+
+.. warning:: Pull requests for substantial features that did not go through the
+   proposal process will be rejected or put on hold.
+
+Formal Process
+--------------
+
+.. image:: fig/change-proposal-process.excalidraw.png
+
+:Creation: To open a proposal, the author submits a GitHub issue following the
+  ``proposal`` template.
+:Review: The proposal may receive feedback from the community, which should be
+  incorporated by the author. Moreover, the assigned technical team triages the
+  proposal and assigns one of its members to manage the process. The technical
+  team discusses the proposal and provides feedback. To increase transparency,
+  the results of these discussions are summarised publicly.
+:Decision:
+  The technical team decides to **accept**, **postpone**, or **reject** the
+  proposal based on the outcomes of the discussion and feedback from the
+  community.
+:Initial Design:
+  If the proposal has been accepted, the authors complete an initial design document
+  and submit it to the repository (:file-ref:`doc/dev/design`)
+  in the form of a pull request. The design document has the status **WIP** and
+  is linked to the WIP section of :doc:`design/index`. Once that pull request is
+  approved and merged, the proposal issue is closed. A new issue (following the ``Work Item``
+  template), owned by the design proponent, is open to track its evolution
+  towards its final form. The title of the issue may be of the form:
+  ``<topic>: finalize design``.
+:Design Improvements:
+  Multiple revisions to the WIP document may be submitted and reviewed as PRs.
+  Participants may discuss any change required via the tracking issue.
+:Final review:
+  Once the document reaches a form that appears consensual, the technical
+  team starts the final comment period, together with a proposition to
+  **accept**, **postpone**, or **reject** the design.
+
+  The **final comment period** lasts **ten calendar days** and is advertised, such that
+  stakeholders have a chance to lodge any final objections before a decision is
+  reached. If no major comments are raised during the final comment period, the
+  proposed action (accept, postpone, reject) is acted; otherwise, the
+  proposal goes back to the review step and is discussed further.
+
+  Following the decision, the document's status is changed to one of **Active**, **Postponed**,
+  or **Rejected**, the design document is linked to the corresponding section of the index,
+  and the tracking issue is closed. If the design's new status is **Active**, a new tracking
+  issue is open for its implementation.
+:Implementation:
+  The design is implemented typically, but not necessarily, by the authors.
+  The implementation is submitted as one or more pull requests. The implementation will be
+  reviewed; acceptance of the design does not automatically imply that its implementation
+  will be accepted.
+
+  Once the implementation is deemed complete, the design document's status is changed to
+  **Completed**, it is linked to the corresponding section of the index, and the
+  implementation tracking issue is closed.
+
+  Should a decision be made to abandon or postpone the implementation, the design document's
+  status is changed to **Postponed**, **Outdated**, or **Rejected**; depending on the reason
+  for the decision.

+**********************************************
+Border Router Performance Optimized Redesign
+**********************************************
+
+- Author: Justin Rohrer
+- Last Updated: 2023-05-25
+- Status: **Completed**
+- Discussion at: `#4334 <https://github.com/scionproto/scion/issues/4334>`_
+
+Abstract
+===========
+
+Right now, the performance of the border router is very much limited because a single goroutine per
+border router interface is responsible for reading, parsing, processing and forwarding the packets.
+
+Background
+===========
+
+The current border router design was not created with performance in mind.
+Previously, there also existed a design which did something similar than the proposed design in
+this document.
+`See <https://github.com/scionproto/scion/tree/92531f5cb62197b9d705001c13e5a6bdb7ba1fa4/go/border>`_.
+Redesigning the current router pipeline is expected to lead to significant performance improvements.
+
+Proposal
+========
+
+The pipeline gets changed to have seperate goroutines for the receiving, processing and forwarding steps.
+This will lead to a much higher performance because the expensive processing logic is moved to other
+goroutines and to improve the performance we can just increase the number of processing routines.
+By introducing packet reuse we do not have to allocate memory at runtime to store the packets because we
+have preallocated memory.
+
+Design
+--------
+
+The border router will consist of three layers, the receiving, the processing and the forwarding layer.
+The communication between those layers are implemented as go channels.
+
+Receivers
+^^^^^^^^^^^
+
+There is one receiver per border router interface that is responsible for batch-reading
+the packets from the network socket, identifying the source and flowID and using them to identify which
+processing routine has to process the packet.
+Then the receiver enqueues the packet to that processing routine.
+If the queue of that processing routine is full, the packet will be dropped.
+All receivers share a pool of preallocated packet buffers that they can use to store the packets they
+receive.
+This can be implemented as a go channel of packets where the receiver reads a certain amount of packets,
+updates the pointers of the ipv4.Message.Buffers to the buffer inside those packets and then performs
+a batch read.
+
+Processing Routines
+^^^^^^^^^^^^^^^^^^^^^
+
+There are several processing routines and slow-path processing routines
+in the border router that are responsible for processing the received packet.
+The actual processing logic remains unchanged.
+If the processing routine identifies a packet that belongs to the slow-path, the processing routines
+enqueues the packet to a slow-path processing routine. If the queue of the slow-path processing routine
+is full, the packet will not be processed at all. In this case the buffer is immediately returned to
+the receivers.
+Once a packet is processed, it gets enqueued to the forwarder which is responsible for the egress
+interface.
+If the queue of the forwarder is full, the packet will be dropped and the buffer returned to the
+receivers.
+
+Forwarders
+^^^^^^^^^^^
+
+There exists one forwarder per border router interface that is responsible for
+forwarding the packets over the network that it receives from the processing routines. It collects
+packets from the go channel up to the point where either no further packet is available or the batch
+size is reached.
+Then it forwards the packets as a batch.
+Afterwards it returns the buffers back to the receivers.
+
+.. image:: fig/border_router/br_design.png
+
+Mapping of processing routines
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To prevent any packet reordering on the fast-path, we map the flowID together with the full address-header, see
+`SCION header documentation <https://github.com/scionproto/scion/blob/master/doc/protocols/scion-header.rst>`_
+to a fixed processing routine using the fnv-1a hash function together with a random value which is generated
+on startup to prevent pre-computations of the exact mapping.
+To mitigate the sticky-zero property of the fnv-1a hash function when hashing, we take the random value first
+and the flowID and address-header afterwards.
+
+Initial parsing in the receiver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To minimize the time that the receivers need to parse the fields needed to map a packet to a worker
+we will use a custom parse function that just parses the fields that are needed for the mapping.
+The values of those fields will be the same as if they would have been parsed with the slayers.SCION
+parse function.
+
+
+Slow path
+^^^^^^^^^^^
+
+During processing, packets that have to follow the slow path are identified and forwarded to the
+slow-path processing routines.
+To do so, we hand over the current buffer to the slow-path routine together with the error codes.
+Because of that the slow-path processing routine might have to redo some of the parsing if necessary.
+The original processing routine can immediately continue processing its other packets once it forwarded the
+slow-path packet to the slow-path routine without the need of doing anything additional compared to the usual
+packet processing.
+Rate limiting of slow-path operations is not implemented explicitly, but only implictily through
+specifying the number of slow-path processing routines in the configuration.
+In case a packet is identified to belong to the slow path but the queue of the slow path is full, the
+packet is dropped.
+Packets currently identified for slow-path are:
+
+- Malformed packets
+
+- SCMP traceroute packets
+
+Processor queue size
+^^^^^^^^^^^^^^^^^^^^^^
+
+The processor queue size will be automatically determined as follows:
+
+.. code-block:: text
+
+    processorQueueSize := max(ceil(numReaders * readBatch / numProcessors), readBatch)
+
+Pool size
+^^^^^^^^^^^
+
+The pool size will be set by calculating the maximum number of packets in-flight through the system:
+
+.. code-block:: text
+
+    pool_size := numReaders * readBatch + numProcessors * (processorQueueSize + 1) + numWriters * (writerQueueSize + writeBatchSize)
+
+Configuration
+---------------
+
+The configuration of the border router will remain in the border router toml file.
+The following configuration entries are added:
+
+Number of processing routines (N)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By configuring the number of processing routines one can specify the number of goroutines that are able
+to process packets in parallel.
+Unlike the other settings, the number of the processing routines are directly taken from the
+environment variable GOMAXPROCS.
+
+Number of slow-path processing routines (M)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By configuring the number of slow-path processing routines one can specify the number of goroutines that
+process the packets on the slow-path.
+An optimal value could be a percentage of the number of processing routines or even a fixed number.
+A default value would be 1.
+
+Read-write batch size
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+By configuring the batch size one can specify how many packets are read or written
+from / to a network socket.
+A default value for both batch sizes would be 256.
+
+UDP read-write buffer
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This setting allows to configure the UDP read and write buffer of the sockets.
+The actual applied values are subject to the system rmem_max.
+A default value would be 1MB.
+
+Considerations for future work
+--------------------------------
+
+Multiple receivers per border router interface
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+We could deploy multiple packet receivers per border router interface and use eBPF to make sure that
+all packets that belong to the same flow are received by the same receiver.
+Because the rest remains unchanged we would still have the "no-reordering" guarantee and significantly
+increase the read speed.
+
+Lock goroutines to threads
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The CPU affinity by locking the goroutines to threads and CPU cores can later be studied.
+
+Replace go channels with custom ring buffer
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In the future we might want to replace the go channels that are used for communicating between the
+goroutines with custom ring buffers in case this provides higher performance.
+
+Traffic control (scheduling)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+With the implementation as described in this document the forwarders process the packets from one
+single queue.
+In the future we can use additional queues for prioritized traffic between the processing routines and
+the forwarders.
+See `PR 4054 <https://github.com/scionproto/scion/pull/4054>`_.
+
+UDP generic segment offloading (GSO)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In the future we could add UDP generic segment offloading (GSO) for the connections between border router
+of different ASes to improve the performance even more.
+Such an implementation would be feasible in the future because we would just have to identify
+which border router interfaces are affected and for them make some changes to the IO parts.
+
+UDP generic receive offload (GRO)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In the future we could add UDP generic receive offload (GSO) which seems to better perform than just
+recvmmsg and would therefore improve the performance even more.
+Such an implementation would be feasible in the future because we would just have to identify
+which border router interfaces are affected and for them make some changes to the IO parts.

+
+Rationale
+==========
+
+One packet pool per receiver vs one packet pool for all
+---------------------------------------------------------
+
+There was the option to use a packet pool per receiver or a larger one for all receivers.
+The advantage of using a single packet pool for all receivers are that we don't have to keep track to which
+receiver the buffer has to be returned and that the total amount of memory we have to allocate would be smaller.
+
+Packet pool as channel vs stack
+---------------------------------
+
+If we implement the packet pool as a channel we can make use of the fast and optimized implementation by go
+but if the channel size is too large, the packets might not reside in the cache anymore.
+On the other hand if we use a stack we would not have the problem that problem but now all goroutines that
+try to read or write to the buffer pool are now fighting over the lock.
+Both solutions have advantages and disadvantages but I would suggest to implement it as a queue because
+go already provides a good implement for that and if we later realize that the other solution would lead to
+better performance, we could still change it.
+
+Compatibility
+===============
+
+This is not a breaking change, just a performance improvement.
+All other components will be able to interacet with the border router the same way as before.
+
+Implementation
+================
+
+The implementation as suggested in the design document can be implemented in seperate pullrequest to
+make them easier to review.
+All those changes below should lead to a border router following this design document.
+
+- Restructure the router/dataplane.go file to have a reading, processing and forwarding functionality together with buffer reuse support
+
+- Add slow-path support
+
+- Add configurability for the new functionalities

+Abstract
+========
+SCION packet headers contain a SRC address to which packets should be returned. This address needs to be
+visible/reachable by the first-hop border router, assuming that the path gets simply reversed by the peer.
+This address may not be easy to discover if the sender is separated from the receiver by a NAT.
+
+We want to propose a solution that allows SCION endhosts (and endhost libraries) to discover and use
+the address that is visible to the first hop border router as the source host address in outbound packets.
+The most elegant and most reliable solution appears to be to have
+the border router itself detect the NATed IP/port and report it to the client (to the sending endhost).
+
+Background
+==========
+Scenario: A client sends a packet to a server, containing the clients (assumed) address/port as SRC address. The server
+receives the packet and uses the SRC address/port as DST in the response packet. Back in the destination AS, the border
+router (BR) uses the DST address/port from the response packet to forward it to the client.
+If the client is behind a NAT or similar, the DST address/port (originally the SRC address) must be the address/port at
+the NAT as seen by the border router.
+
+The problem we are trying to solve is putting the correct SRC address/port into outbound SCION packets.
+
+There are many solutions to deal with NATs. In our case, if we assume that packet headers may (at some point) need
+to be signed, we need a solution that allows a client to inject the correct SRC IP and port into a packet.
+"Correct" meaning the IP and port that is visible by the first hop border router so that it can return answer packets
+from a remote host to the client endhost.
+
+The basic idea is that the client endhost sends a packet to a destination (let's call it "detector") outside of the
+NAT and the detector responds to the sender with a packet that contains the IP and port as seen by the detector.
+One example of this approach is the `STUN protocol <https://en.wikipedia.org/wiki/STUN>`_.
+
+One complication is that the local AS of the sender may be split into different subnets and that border routers
+are not all in the same subnet.
+Another complication is that some NATs may change their port mapping if a client endhost connects to a new
+remote IP or port or uses a different local port.
+
+Therefore, it is desirable for the detector to be not only in the same AS and same subnet as the BR, but ideally at the
+same IP address, listening on the same port.
+Similarly, it is desirable for the client to use the same local port when connecting to the detector and for actual data
+packets to the border router.
+
+Separately, we need to specify a way how the client endhost can discover the "detector", i.e. its IP address and port.
+In case the detector shares and IP and possibly even port (or uses a fixed port) with the border router, this
+discovery is straight forward.
+If the port is flexible or the detector runs on a different IP then we need to find a different solution, probably
+as an extension to the bootstrapping service.
+
+Proposal
+========
+Proposed change: Extend the border router to detect NATed addresses/ports and report them back to a client endhost.
+
+Ideally the solution would listen on the same port that would also be used for normal traffic forwarding.
+Alternatively, it may be feasible (depending on how sensitive the NAT is) to use a different (fixed) port to
+accept requests for reporting addresses.
+
+To avoid potential misunderstandings: this proposal only addresses the problem of SCION clients behind NATs. It is not
+the goal to also support NAT traversal techniques such as NAT hole punching SCION-based servers and peer-to-peer
+scenarios.
+
+The implementation on the protocol level could be done in several ways:
+
+1.  STUN: The BR needs to detect if an incoming packet is a STUN packet, and if it is, respond to the STUN request.
+
+    -  Advantages: STUN is a well known and mature protocol. There are STUN libraries available in many programming languages.
+       It should be easy to implement this.
+
+2.  Extend SCMP with a new INFO message
+
+    -  Advantages: One less dependency on an external library and protocol
+    -  Disadvantages: More standardization effort? How do we solve authentication?
+
+3.  Extend SCMP with a new ERROR message: "invalid source address for first hop pkt", similar to error 33.
+    The router can verify that for first hop packets, the IP src address (and L4 port if applicable) matches the SCION
+    src address (and L4 port).
+    If not, it returns an error. The actual source address would need to be attached somewhere, unless we decide
+    to change the payload so it contains the IP header of the offending packet (and the IP header should contain the
+    NATed IP/port).
+
+    -  Advantages: One less dependency on an external library and protocol. Also one roundtrip less in case an endhost
+       doesn't sit behind a NAT or similar.
+    -  Disadvantages: Conceptually a bit of a hack. The BR would need to check every outbound packet as part of the fast
+       path. More standardization effort? How do we solve authentication?
+
+Rationale
+=========
+The main reasons for integrating the functionality with the BR are:
+
+-  Reliability: The border router is almost guaranteed to see the correct IP/port on the NAT, especially when using the
+   same port for NAT detection traffic and routing traffic. All other approaches rely on the leniency of the NAT to use
+   the same port even if the NAT detector and border router have different ports or even IPs.
+-  Time to rollout: changing the border routers should be much easier and faster than getting NAT vendors to implement
+   SCION compatibility or to get rid of NATs completely in home networks.
+   A short time until rollout seems important because people are already running into this problem.
+
+Alternatives:
+
+-  The SRC address/port is updated by the border router to reflect what the border router sees as source address.
+   Problem:
+
+   -  Complicates cryptographically protecting the header if the header must be modifiable by border routers,
+      e.g. for `SPAO <https://docs.scion.org/en/latest/protocols/authenticator-option.html>`_.
+
+-  The SRC address/port is updated by the NAT. This is similar to having the border router update SRC IP/port.
+
+   - Complicates cryptographically protecting the header if the header must be modifiable by NATs.
+   - Requires cooperation of NAT suppliers to include and roll out SCION support to all their devices.
+
+-  Use separate STUN servers. This is a possibility, but adds setup complexity and may not work in all cases. Every
+   subnet of an AS that has a border router would also need a STUN server. Moreover, if the STUN server uses a different
+   IP (or port) than the border router, then the NAT may decide to use a different port mapping,
+   i.e. the STUN server may not see the same IP/port tuple on the NAT that the border router sees. Disadvantages:
+
+   -  This approach may be be problematic with sensitive NATs.
+   -  We need to somehow standardize the STUN IP/port and/or communicate it to endhosts, e.g. via the topology.json file
+      or the bootstrapping service.
+
+-  Remove all NATs and use IPv6 instead. This is technically possible but unlikely to happen anytime soon, especially
+   because scarcity of IPv4 addresses is not the only reason why NATs are deployed.
+
+Compatibility
+=============
+
+Breaking changes
+----------------
+
+This change should not break anything.
+
+However, there are some points that may need more discussion:
+
+- Return paths: the proposal requires packets that come from a server to arrive through the same BR that was used for an
+  outgoing request. This currently seems to be the default behavior of servers, but it is not a behavior required
+  by the current standard.
+
+- Dispatcherless port range: What if the the port mapping at the NAT doesn't result in a L4 port that is within the
+  `"dispatched_ports" range <https://docs.scion.org/en/latest/dev/design/router-port-dispatch.html>`_ ?
+  The last-hop BR would then choose the fixed end-host data port (default 30041) as the underlay UDP/IP destination port
+  and NAT mapping would fail. Contrary to the previous point, this problem would at least be detectable by the endhost
+  based on the proposed NAT IP/port discovery mechanism.
+
+- All client libraries (snet/pan, jpan, ...) will have to accept incoming packets where the underlay UDP port does not
+  match with the L4 port, i.e., the underlay port could be the local receiver port (rewritten while passing the NAT)
+  whereas the L4 port will still be the NATed port.
+
+Transition
+----------
+
+- An "old" client without expectation on NAT IP/port discovery support on the router would simply not use this feature.
+  No additional problem here.
+- A "new" client sending a NAT IP/port discovery request to an "old" border router should simply fail because the router
+  should simply drop a packet that it cannot process.
+  The client should then time out and report that the external NAT address could not be established. Instead of timing
+  out it could also optimistically assume that no NAT is involved. -> TBD
+
+Implementation
+==============
+[A description of the steps in the implementation, which components need to be changed and in which order.]
+
+TBD when decision for one of the proposed implementation variants has been made.

+  documentation are updated.
+
+  The design document is only updated if amendments to the described design are
+  found to be necessary during this phase.
+- **Completion and Freeze**:
+  Once all parts of the implementation are completed, the design document is
+  marked as **Completed** and linked to section :ref:`design-docs-completed`.
+
+  After this point, the design document is frozen as historical record and no
+  longer updated. Later substantial changes undergo the entire process again,
+  creating new design documents where appropriate.
+
+  During implementation the design may also become suspended (**Postponed**)
+  or abandoned (**Rejected** or **Outdated**).
+
+- **Replacement**:
+  If the implementation has changed so much that a design document is no longer
+  a useful reference for the current system, it's status is changed to **Outdated**
+  and it is linked to section :ref:`design-docs-outdated`.

+
+TL;DR
+=====
+
+For any hardware platform, given:
+
+-  :math:`L`: the router benchmark packet length (in bytes)
+-  coremark: The coremark benchmark result on the platform
+   (dimensionless)
+-  :math:`C`: The memmove benchmark result of the platform expressed (in bytes/s)
+-  rate: The benchmark result of the router on the platform, using three cores (in pkts/s)
+-  :math:`M`: an experimentally determined constant of value 400
+-  :math:`I`: a dimensionless number reflecting the router code’s performance
+
+At least for :math:`L` = 172, the following relationship is true:
+
+.. math::
+
+  I ~= (1 / coremark + (M \times L / C)) \times rate
+
+Introduction
+============
+
+The benchmark was ran on three configurations, the br_transit test case
+produced the following data points:
+
+-  An APU2 running openwrt:
+
+   -  4 amd cores 1GHz
+   -  Coremark (per core) 3044
+   -  memmove benchmark 248 MiB/s (1.9 Gib/s)
+   -  line rate 70K pkts/s
+   -  Observed throughput: 45377
+
+-  A lenovo laptop running the CI benchmark:
+
+   -  10 i7 cores 4GHz
+   -  Coremark (per core) 29861
+   -  memmove benchmark 3928 MiB/s (31 Gib/s)
+   -  line rate 1.4M pkts/s (veth)
+   -  Observed throuhgput: 639764 pkts/s
+
+-  Our CI system running the CI benchmark:
+
+   -  4 xeon cores 3.5 GHz
+   -  Coremark (per core) 28659
+   -  memmove benchmark 8102 MiB/s (64 Gib/s)
+   -  line rate unobserved (veth, assumed similar to laptop)
+   -  Observed throuhgput: 736357 pkts/s
+
+Important: all benchmarks have been run with only 3 cores assigned to
+the router. The cores are chosen by the benchmarking program to be of
+the same type (i.e. no mix of performance and energy-efficient cores).
+Hyperthreading is not used.
+
+See “The problem with the influence of core count”.
+
+Where might the time go
+=======================
+
+With a single core, the time processing a packet is presumed spend as follows...
+
+Variables:
+
+-  let :math:`b` = benchmark packet size (152)
+-  let :math:`e` = empty packet size (34)
+-  let :math:`m` = max packet size (1520)
+-  let :math:`po` = packet overhead time in seconds
+-  let :math:`L` = the length of a given packet [bytes]
+-  let :math:`x(L)` = packet-length dependent xmit time [s]
+-  let :math:`t(L)` = total packet transmission time for :math:`L` [s]
+-  let :math:`R` = nominal wire rate in decoded [bit/s]
+-  let :math:`X` = line slowness [seconds/byte]
+-  let :math:`bm(L)` = total benchmark packet processing time (including transmission and pkt overhead) [s]
+-  let :math:`ro` = router overhead [time added by processing one packet in the router] [s]
+-  let :math:`p(L)` = packet-length dependent router processing time for :math:`L` [s]
+-  let :math:`r(L)` = total processing time in router for :math:`L` [s]
+-  let :math:`C` = nominal copy rate in [bit/s]
+-  let :math:`Y` = copy slowness [seconds/byte]
+
+Transmission:
+
+-  assume :math:`x(L) = X \times L` [X is s/byte]
+-  assume :math:`t(L) = po + x(L)`
+-  assume :math:`X = 8/R`
+-  po is unknown
+
+Router:
+
+-  assume :math:`p(L) = Y \times L` [Y is s/byte]
+-  assume :math:`r(L) = ro + p(L)`
+-  assume :math:`Y = 8/C` [that is, the length-dependent processing time
+   is ~copying the packet]
+-  ro is unknown
+
+Aggregate:
+
+-  assume :math:`bm(L) = MAX(r(L), t(L))`
+
+What can be inferred from observations
+======================================
+
+APU2
+----
+
+Observed:
+
+-  :math:`t(m) = 1s/70K` (106 Mbyte/s, iperf3 with fast machine/nic -- assuming full packets)
+-  :math:`bm(b) = 1s/45377` (benchmark run)
+-  :math:`R = 1Gb/s` (nominal NIC rate)
+-  :math:`C = 1.9Gb/s` (mmbm - Go memmove small packets)
+
+Therefore:
+
+-  :math:`po = t(L) - x(L) = t(m) - x(m) = 1/70K - X \times m = 1/70K - 1520 \times 8 / 1G`
+   :math:`= 0.000002126 s`
+-  :math:`t(b) = po + x(b) = po + X \times b = 0.000002126 + 172 \times 8 / 1G = 0.000003502 s`
+-  :math:`bm(b) = 0.000024 s`
+
+Since :math:`bm(b) > t(b)`, we can conclude that the router isn’t processing at line speed,
+so :math:`bm(b) = r(b)`. That is :math:`bm(b)` reflects the router’s code performance.
+
+Therefore:
+
+-  :math:`r(b) = bm(b)`
+-  :math:`ro = r(b) - p(b)`
+-  :math:`ro = bm(b) - Y \times b = 1s / 45377 - 8 \times 172 / 1.9G = 0.00002131 s`
+
+Laptop local test
+-----------------
+
+Observed:
+
+-  :math:`t(m) = 1s/1.4M` (iperf3 on non-loopback ethernet interface)
+-  :math:`bm(b) = 1s/639764` (benchmark run)
+-  :math:`R = 17Gb/s` (same iperf3 run as t(m). Assuming po is neglictible)
+-  :math:`C = 31Gb/s` (mmbm - Go memmove small packets)
+
+Therefore:
+
+-  :math:`po = t(L) - x(L) = t(m) - x(m) = 1/1.4M - X \times m = 1/1.4M - 1520 \times 8 / 17G`
+   :math:`~= 0` (expected since we neglected po to derive R)
+-  :math:`t(b) = po + x(b) = 0 + X \times b = 172 \times 8 / 17G = 0.00000008 s`
+-  :math:`bm(b) = 0.000001563`
+
+Since :math:`bm(b) > t(b)` we can conclude that the router isn’t processing at line speed,
+so :math:`bm(b) = r(b)`. That is :math:`bm(b)` reflects the router’s code performance.
+
+Therefore:
+
+-  :math:`r(b) = bm(b)`
+-  :math:`ro = r(b) - p(b)`
+-  :math:`ro = bm(b) - Y \times b = 1s/639764 - 8 \times 172 / 31G = 0.000001519 s`
+
+Assumption of less-than-line-rate
+---------------------------------
+
+The case where the line rate is low enough to be the bottleneck isn’t
+very interresting. Because it is so clearly not the case with the
+hardware available to us, we will consider only the case where the wire
+is faster than the router.
+
+Tentative predictive model
+==========================
+
+Initial assumptions
+-------------------
+
+Variables:
+
+-  let :math:`pbm(L)` = predicted benchmark processing time for length :math:`L`
+-  let :math:`pt(L)` = predicted total transmission time for length :math:`L`
+-  let :math:`pp(L)` = predicted lenght-dependent processing time for :math:`L`
+-  let :math:`pro` = predicted router per-packet overhead
+-  let :math:`N` = The number of cores devote to packet processing
+-  let :math:`I` = The router’s code performance index; a measure of the code’s efficiency
+
+We assume that the length-independent time spent processing is inverse
+proportional to:
+
+-  coremark
+-  :math:`N`
+-  :math:`I`
+
+In all likelyness each packet is processed by one core, but we do not
+known that for sure. So, for now, we’re assuming that N packets are
+going to be processed by N cores as fast as 1 packet by one core (the
+difference, if any, would be an effect of the code’s quality and so
+reflected by the performance index. So, the statistical processing time
+per packet is 1/N that of single core processing.
+
+We assume that the length-dependent time processing the packet is proportional to:
+
+-  The length of the packet
+
+...and inverse proportional to:
+
+-  :math:`I` (in this case, reflecting how little copying is done)
+-  :math:`C`, The memcpy rate.
+
+Model
+-----
+
+From our assumptions, (and single I simplification) we have:
+
+-  :math:`pro = 1 / (I \times coremark)`
+-  :math:`pp(L) = 8 \times L / (I \times C)`
+-  :math:`pbm(L) = pro + pp(L)`
+   :math:`= 1 / (I \times coremark) + 8 \times L / (I \times C)`
+   :math:`= (1 / I) \times (1 / coremark) + (8 \times L / C))`
+-  :math:`I = (1 / coremark + (8 \times L / C)) / pbm(L)`
+
+Since we ran the same router on both benchmarking platform, we should be
+able to infer the same I from the benchmark result and hadrware
+characteristics. (or, at least, close).
+
+If so, that’s our platform independent performance index. That is, given
+a benchmark on any platform, with known C and coremark, we can find this
+number and use it to predict the performance of the same code on any
+other platform with known C and coremark.
+
+The influence of caches and TLBs
+--------------------------------
+
+Efforts to improve the precision of the mmbm benchmark (which attempts
+to measure :math:`C` showed that trying to model the behavior of caches
+and TLBs is extremely challenging. For example:
+
+-  The cache and TLB benefits do not disappear as the working set
+   exceeds the cache/TLB size. Nor are those benefits fully realized
+   while the working set remains within the cache size. The precise
+   behavior varies by CPU model.
+-  Page table walks polute the cache for some CPU models, but others
+   have a hidden cache exclusiveley for page table entries.
+-  Copying many 1 byte packets within a 128 pages arena takes
+   consistently more time than within an 8192 pages arena in at least
+   one CPU model. The reason for this remains a mystery.
+
+Multiway associative caches, combined with mostly secret replacement
+policies, undocumented caches, and intractable activity by the OS and
+the Go runtime make it extremely challenging to predict how a given
+workload (even a synthetic one) will perform on a given CPU. So far,
+this has not been achieved.
+
+As a distant second best, the mmbm benchmark only measures the copy
+speed in a handful of cases. For the purpose of modeling we use one case
+that is modeled after what the reference router does under benchmark. It
+is expected to cause non-temporal TLB access but a 100% hit rate on the
+L2 data cache, but that is not reflected reliably in the router’s
+benchmark results.
+
+By relying on these simple macroscopic metric and by tuning empirical
+parameters, we may be able to better approximate a cross-hardware router
+performance index. To that end we need to find or tune two additional
+parameters M and N such that:
+
+:math:`I = (1 / coremark + M * (8 \times L / C) + N) / pbm(L)`
+
+M represents the proportion in wich memory performance and arithmetic
+performance contribute to throughput. Such a ratio needs to exist for a
+translatable performance index.
+
+N represents a fixed hardware-dependent per-packet cost that, judging by
+the above results the model has failed to anticipate. We could speculate
+that this cost is related to interacting with network interfaces. If
+that is the case, a measure of it needs to be incorporated in our suite
+of microbenchmarks.
+
+Given a known N for three different systems, we could probably infer M.
+However, N is a property of each platform. It has to be measured.
+
+Inferred router performance index
+=================================
+
+The performance index has to be such that pbm(L) is equal to bm(L) as
+observed in at least two experiments. Note that only one type of
+forwarding is looked at - br_transit. Routers might have different
+performance indices for different packet types (although only small
+variations are expected).
+
+If we ignore M and N for now, (i.e. M = 1, N = 0), we have the
+following:
+
+.. _apu2-1:
+
+APU2

+
+-  :math:`coremark = 3044`
+-  :math:`C = 1.9Gb/s`
+-  :math:`L = 172`
+-  :math:`pbm(L) = 1s/45377`
+-  :math:`I = (1 / coremark + (8 \times L / C)) / pbm(L)`
+   :math:`= (1 / 3044 + (8 \times 172 / 1.9G)) \times 45377`
+   :math:`~= 14.93`
+
+Laptop
+------
+
+-  :math:`coremark = 29851`
+-  :math:`C = 31Gb/s`
+-  :math:`L = 172`
+-  :math:`pbm(L) = 1s/639764`
+-  :math:`I = (1 / coremark + (8 \times L / C)) / pbm(L)`
+   :math:`= (1 / 29851 + (8 \times 172 / 31G)) \times 639864`
+   :math:`~= 21.46`
+
+CI system
+---------
+
+-  :math:`coremark = 28659`
+-  :math:`C = 64Gb/s`
+-  :math:`L = 172`
+-  :math:`pbm(L) = 1s/736357`
+-  :math:`I = (1 / coremark + (8 \times L / C)) / pbm(L)`
+   :math:`= (1 / 28659 + (8 \times 172 / 64G)) \times 736357`
+   :math:`~= 25.7`
+
+...Not close.
+
+The CI system has a coremark similar to that of the laptop but much
+faster memory copy. So memory copy may have a greater influence than
+coremark. In other words, the hypothetical M value (see the previous
+section) is much greater than 1. For example, assuming N=0, a value of
+400 for M yields performance indices of 28, 33 and 32 for APU2, the
+laptop, and the CI system, respectively. So, tuning is at least
+possible. This is purely speculative, though. We do not know if N can be
+neglected.
+
+Application to router improvement
+---------------------------------
+
+Some of the lessons learned during the benchmarking effort:
+
+-  The router performance is probably dominated by TLB misses.
+-  The router keeps 9K buffers, which makes 3/4 of all buffers
+   missaligned. That extra 1k is paid with an extra TLB miss.
+-  Small packets are dispersed over large buffers. Each small packet
+   requires at least one page access.
+-  At steady state, all buffers are eventually occupied, therefore we
+   cycle through the whole set. Since that set is much larger than the
+   cache, we loose all temporal locality: all packets get evicted from
+   the cache, possibly more than once, during processing.

+End hosts without dispatcher
+============================
+
+- Author: Matthias Frei.
+  Originally proposed by Sergiu Costea.
+- Last updated: 2024-03-26
+- Status: **Active**
+- Discussion at: https://github.com/scionproto/scion/issues/3961
+
+Abstract
+--------
+
+Remove the dispatcher, because it causes a variety of problems (some merely implementation problems, others inherent to the design).
+SCION applications open a UDP underlay socket directly, and use the corresponding port as the UDP/SCION port.
+The router in the destination AS inspects the Layer 4 UDP header and delivers the packet to this port.
+
+Background
+----------
+
+The SCION router in the destination AS delivers a packet to the end host at the specified destination address.
+The packet is delivered to the end host over UDP/IP, using a fixed end-host data port (30041).
+On the end host the packet is then delivered to the appropriate application socket determined by the protocol and port number; only UDP/SCION (and SCMP) are currently supported.
+We do not have operating system support for SCION on any platform, so this last step happens in user space, in the "dispatcher".
+
+Applications create UDP/SCION sockets by registering with the dispatcher, establishing a connection to the dispatcher's unix domain socket.
+The application then receives and transmits SCION packets (exclusively) over this unix domain socket connection.
+
+The dispatcher also implements other end host stack functionality; in particular, it replies to certain SCMP messages like SCMP Echo (ping).
+
+Problems
+^^^^^^^^
+This dispatcher is the cause of many issues:
+
+- It is a single point of failure for the SCION network stack of a host. If it goes down, a lot of processes (control service, gateway, tooling) go haywire.
+- It lives in user space, moving every forwarded packet from kernel space to user space and back to kernel space, meaning a performance hit.
+- It requires a UNIX DOMAIN stream socket, meaning awkward volume mounts in dockerized environments (and awkward resource cleanup/access management).
+- It imposes stateful connections that need to be reestablished by client applications if the dispatcher goes down and then up. This has been the cause of many bugs in the past, and the performance impact of the reconnection logic is currently unknown.
+- The UNIX DOMAIN socket is a stream, while the data being sent/received are packets. This requires packetization logic and slows forwarding even further.
+- It has cost us a lot of time in performance tuning, because we never knew if it is the root cause of performance problems in apps like the SCION IP gateway.
+- It is an additional application to configure/deploy/operate on which, crucially, other applications depend on. This has caused headaches in testing where apps need to retry to connect to the dispatcher if it is not up yet, and it led to dependencies in docker-compose.
+
+  This is also a big blocker for deploying multiple separate SCION-enabled applications to a larger variety of platforms.
+  For example, on mobile platforms (iOS, Android) there is simply no good way to install and start the dispatcher as a shared dependency of multiple applications.
+  Attempts to do so seem to require additional user interactions (in the form of: "please install and enable this other application"), which effectively blocks adoption of SCION use in mobile applications for most average users.
+
+- It masks what applications are actually talking on the network, so traditional firewalls cannot filter based on ports and a simple packet capture is often not sufficient to debug.
+- It breaks native network tooling; netstat is ~ useless due to it.
+
+The dispatcher has the following advantages:
+
+- It simulates an end host with full operating system support for SCION, i.e. it's conceptually "correct" and in line with our long-term vision.
+- All SCION traffic is tunneled through a single port; this simplifies connectivity matrices and port firewall rules.
+
+
+Long term vision
+^^^^^^^^^^^^^^^^
+
+In the longer term future, all of the functionality of the dispatcher may be
+included in the operating system's network stack. Applications open a UDP/SCION
+socket directly and the packet dispatching happens in the kernel.
+In this scenario, neither the user-space dispatcher nor the proposed workaround is needed.
+
+Proposal
+--------
+
+For UDP/SCION, SCION applications open a UDP/IP underlay socket directly, and use the corresponding port as the local UDP/SCION port.
+The last SCION router on a path inspects the Layer 4 UDP/SCION destination port to determine the underlay UDP/IP destination port.
+For traffic in the local AS, the source end host determines the underlay UDP/IP destination port analogously.
+
+SCMP
+^^^^
+
+The same procedure applies for SCMP messages, wherever possible.
+For SCMP error messages in response to UDP/SCION packets, the router uses the source port from the quoted offending packet as the underlay destination port.
+For SCMP error messages in response to a packet sent from a local end host, the underlay source address is used directly for the error message.
+
+For SCMP :ref:`Echo Requests <echo-request>` and :ref:`Traceroute Requests <traceroute-request>`, SCION applications open a UDP underlay port on the local host and use this port as the Identifier for the request messages.
+The requests are sent to the destination end host to the default end-host port 30041.
+For SCMP :ref:`Echo Replies <echo-reply>` and :ref:`Traceroute Replies <traceroute-reply>`, the router uses the Identifier field as the destination UDP port.
+
+SCMP Daemon
+^^^^^^^^^^^
+
+The remaining functionality of the dispatcher, namely responding to SCMP echo requests, is implemented in a new, very simple "SCMP daemon".
+This daemon opens UDP/IP port 30041, where it receives and replies to SCMP Echo requests.
+On this port, it will also receive any packet where an appropriate destination port could not be determined (e.g. SCMP error messages for malformed packages).
+These events are only logged and counted, but otherwise no appropriate action is possible.
+
+The SCMP daemon is an optional component for end hosts.
+If it's not running, the host simply doesn't respond to pings.
+
+Service Addresses
+^^^^^^^^^^^^^^^^^
+
+Service destination address resolve to a configured underlay UDP/IP
+address, that is, to an IP *and* a (default) port number.
+
+The common use case for service addresses uses a UDP/SCION destination port of 0. In this case, the default underlay port is used.
+In case any other destination port is set, it overrides the default. The processing here is analogous to UDP/SCION packets with IP destination address type.
+
+Port Unreachable
+^^^^^^^^^^^^^^^^
+
+No SCMP error messages for Port unreachable are sent. On the end host, there is simply no component that could trigger this. Instead, an ICMP port closed message for the UDP/IP port may be triggered.
+Given that the dispatcher currently doesn't even send out these SCMP messages, it does not seem to be worth the effort to translate the ICMP message to an SCMP in the router.
+
+Processing rule
+^^^^^^^^^^^^^^^
+
+1. The underlay UDP/IP destination port for packets towards the destination end host is chosen as follows:
+
+  - UDP/SCION:
+
+      - SVC destination address type and UDP/SCION destination port is 0: default port for resolved service address
+      - Else: UDP/SCION destination port
+
+  - SCMP:
+
+    - :ref:`Echo Reply <echo-reply>`, :ref:`Traceroute Reply <traceroute-reply>`: Identifier field
+    - SCMP error messages:
+
+      - If quoted message is UDP/SCION: UDP/SCION source port
+      - Error message originating from this router to local end host: underlay source address of offending packet
+
+    - any other, in particular :ref:`Echo Request <echo-request>` and :ref:`Traceroute Request <traceroute-request>`: default end-host port 30041
+
+
+.. Hint:: This only applies to the ingress-router in the destination AS at the end of the path.
+   This does not affect the performance of the high-speed core routers that need to forward huge volumes of data.
+
+
+Compatibility
+^^^^^^^^^^^^^
+
+This change "only" affects the intra-AS forwarding, that is, there is no requirement to coordinate this update between different domains.
+
+Within each AS, we still need to be able to migrate to this new underlay without disrupting the network and without a synchronized update of all the hosts and routers of the AS.
+For this, we add two mechanisms:
+
+- the "shim dispatcher"; a simple, stateless UDP packet forwarder running on the updated end hosts, listening on UDP port 30041.
+  It inspects the L4 header and forwards all SCION packets to corresponding underlay port on the local host, following the processing rules for the router outlined above.
+
+  The shim dispatcher allows to update individual hosts before updating all of the routers.
+  The applications can receive the packets on individual UDP underlay ports and don't need to be aware of whether a packet was forwarded with the local dispatcher or was received directly (from the ingress router or an AS-local source host).
+
+- *conditionally* use the underlay UDP/IP destination port determined with the rules above only for specific *port ranges*.
+  These port ranges are AS specific and are included in the topology configuration that end hosts and routers receive.
+
+  As long as there there are no legacy devices/applications using ports in this range, we can update routers without disrupting any old hosts.
+  In this port range, we can operate *new* devices/applications *without* support from the shim dispatcher.
+
+  The processing rule above is extended:
+
+  2. If the underlay UDP/IP destination port determined above, i.e. in processing rule 1, is within the port range specified in the topology configuration,
+     the packet is sent to that destination port.
+
+     Otherwise, the packet is sent to the default end-host port 30041.
+
+  The port range is configured in the ``topology.json`` file in the following format:
+
+    .. code-block:: yaml
+
+       "dispatched_ports": "<min>-<max>"
+
+  The ``min``, ``max`` values define the range of ports ``[min, max]`` (inclusive).
+  The value ``"-"`` explicitly represents an empty range.
+  The value ``"all"`` represents the full range (``1-65535``).
+  If nothing is configured, the port range defaults to an empty range.
+
+  Applications pick ephemeral ports from this range when opening a socket.
+
+
+Update procedure
+""""""""""""""""
+
+With these mechanisms, the update procedure for an individual AS is:
+
+1. Pick a range for ``dispatched_ports``, and ensure that *no* existing applications are using ports in this range.
+
+   The recommended initial port range for the transition is ``31000-32767``.
+   This range is just below the range of ephemeral ports that is assigned by the old dispatcher (32768-65535), ensuring that UDP traffic from legacy end hosts will be unaffected by the port dispatching in the router.
+   On legacy hosts, SCMP echo and error requests currently use random IDs, and thus have a low chance (~2.5%) to pick an ID in the range that is port dispatched by the router. As a preparatory change, the range of IDs can reduced, so that there is no intersection.
+
+2. Update devices, **in any order**, without requiring synchronisation:
+
+   a. Update routers individually and enable ``dispatched_ports`` in their ``topology.json``.
+
+   b. Update hosts individually; replace the dispatcher with the shim-dispatcher, rebuild all
+      applications based on the updated libraries, and enable ``dispatched_ports`` in their ``topology.json``.
+
+3. Once all (or at least a significant portion of the) routers have been updated, new applications/devices can use ports in the range ``dispatched_ports`` without the shim dispatcher.
+
+   Depending on the types and number of end hosts in the AS and the time it takes for updates to be picked up, this state is may occur for anything from a few minutes to months, until ...
+
+4. Once all hosts have been updated, the ``dispatched_ports`` range can be extended to the entire port range.
+   The shim dispatchers can be disabled.
+
+.. Note:: Server applications listening on well-known ports keep using the same ports throughout the
+   process. As stated in 1., these ports should not be part of the initial ``dispatched_ports``
+   range. When the server is updated (2.b), it needs to make use of the shim dispatcher until
+   the port range is extended to the well-known ports, in step 4.
+
+.. Note:: If an AS operator controls all devices in the AS and/or does not plan to allow operating
+   new applications/devices without the shim dispatcher, they can pick the empty range in step 1.,
+   and state 3. is skipped.
+
+
+Long term vision compatibility
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Conversely, if our long term vision materializes and we'd have SCION support directly built-in to the operating system's network stack, then this workaround becomes obsolete.
+In an optimistic scenario, where there are millions of end hosts running SCION-enabled applications, we can not expect that all devices and applications will be updated to the same level of SCION support within a useful time frame.
+Therefore, it will be necessary to be able to gradually phase out the use of this workaround, keeping it around for all the future legacy applications.
+
+.. Note:: In the future, we'd perhaps use a different port, or no longer use UDP/IP but directly IP as the underlay.
+
+The compatibility mechanisms introduced for the update can be reused for this "reverse" transition:
+
+- enable shim dispatcher for services outside of intended ``dispatched_port`` range.
+- shrink ``dispatched_ports`` range and configure this on routers and hosts
+- on individual hosts: enable OS network stack support and update applications, disable shim dispatcher
+
+.. Note:: It's not quite clear how we can practically coordinate that all relevant hosts have (re-)enabled the shim dispatcher.
+   This idea will need more work.
+.. Note:: This should not be considered a promise to never break compatibility for end hosts again.
+
+
+Rationale
+---------
+
+Alternative without router support
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Instead of having the router inspect the Layer 4 data to determine the destination underlay port, we could keep this logic on the end host.
+Applications open IP/UDP sockets for transmitting packets, as above. To receive packets, a (much simplified) dispatcher process
+listens on port 30041 and forwards the packets to localhost:<UDP/SCION destination port>.
+This could also be implemented as a port rewrite step for example in an XDP program.
+
+This has some advantages:
+
+- it retains the "correct" end-host model, packets on the wire don't change
+- it's an entirely end-host local change
+- it also fixes many of the problems listed above related to unix domain sockets, reconnection, etc.
+
+However, this still requires a shared component on the end host if multiple applications want to use SCION concurrently.
+For deployment to mobile platforms, in particular, this is still as much of a blocker as the current dispatcher.
+
+Alternative SCMP handling
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The original proposal did not require the router to inspect SCMP messages.
+All SCMP messages would be forwarded to the default end-host port and dispatched from there to the correct application with the SCMP daemon.
+
+Same issue as above; this still requires a shared component on the end-host if applications should be able to receive SCMP messages.
+SCMP error messages are crucial for efficient fail-over in SCION. Simply omitting these would not be a good option.
+
+Implementation
+--------------
+
+The roadmap would look like the following:
+
+- Prepare:
+   - Reduce the range of IDs used for SCMP echo and traceroute requests, so that it matches the range of ports assigned by the legacy dispatcher (32768-65535).
+
+- Add support for dispatched/forwarded port ranges to the topology.json configuration.
+
+  As the topology.json parsing is lenient about unknown keys by default, the updated topology.json file can still be consumed by "legacy" applications.
+
+- Change SCION applications to use native ``net.UDPConn`` instead of ``reliable.Conn``.
+
+  Remove ``reliable`` package and replace functionality of dispatcher with a simple stateless UDP
+  packet forwarder. This forwarder listens on UDP port 30041. It inspects the L4 header and forwards
+  all SCION packets to corresponding underlay port on the local host, following the processing
+  rules for the router outlined above.
+
+  This "new" dispatcher still replies to SCMP echos.
+
+- Add support for the ``dispatched_ports`` range to the router, changing its behavior to set the
+  UDP destination underlay port as described above.
+
+- Future release:
+   - remove support for old UDP underlay with default port 30041.
+     Remove the packet dispatching/forwarding functionality from "dispatcher".
+     Only SCMP echo responder remains in dispatcher. Rename to "SCMP Daemon" (scmpd).
+   - set suitable default for port range in ``dispatched_ports`` topology configuration.

+SCMP Authentication
+*******************

+- Author(s): Matthias Frei
+- Last updated: 2024-05-23
+- Discussion at: :issue:`3969`
+- Status: **Postponed**
+
+Reason for postponment: no clear consensus that this is the right approach. See "Discussion" section.
+Experimental support in router, added in :issue:`4255`.
+
+Abstract
+========
+:doc:`SCMP </protocols/scmp>` error messages can potentially be abused by an attacker to signal spurious network errors, attempting to degrade or deny a victim's use of a service or network path.
+Employ cryptographic validation to check authenticity and authorization of the sender of an SCMP message.
+
+Background
+==========
+
+SCMP error messages can potentially be abused by an attacker to signal spurious network errors.
+Implementations of TCP/IP, face a similar challenge with ICMP error messages; in order to avoid acting on fraudulent errors, they carefully validate ICMP messages using their internal state machine and ignore errors that appear unlikely to happen e.g. after the connection has already been established RFC 5927.
+QUIC goes even further and simply ignores all ICMP errors, except those related to MTU discovery.
+
+This approach can only mitigate the problem.
+Furthermore, this approach is not sufficient in SCION as the applications/transport layer on end hosts are expected to react to events in the network, e.g. path failures, by changing to a different path.
+The occurrence of such events is independent of the transport's internal state machine.
+This aspect does not exist in IP based internet, where the network will transparently adapt the routing (or not) on faults.
+
+To address this, we use :doc:`/cryptography/drkey` and the :doc:`/protocols/authenticator-option` to authenticate SCMP messages.
+
+Proposal
+========
+
+As noted in the :doc:`/protocols/scmp`, support for the SCMP protocol is optional for SCION nodes.
+This proposal *mandates* authentication for most SCMP messages.
+Should this proposal be adopted, it extends the SCMP specification, and terms MUST/MUST NOT/MAY used below will apply to all SCION nodes with an SCMP implementations.
+In other words, SCION nodes either need to implement the additional processing rules for SCMP messages described in this document, or remove SCMP support altogether.
+
+.. _scmp-spao:
+
+SCMP with SCION Packet Authenticator Option
+-------------------------------------------
+
+SCMP messages can be authenticated with a MAC based on a symmetric key established with the :ref:`DRKey infrastructure <drkey>`.
+The MAC is transported in the :ref:`authenticator-option` End-to-End extension header.
+
+The Authenticator MAC algorithm is AES-CMAC (identifier :code:`0`).
+
+SCMP error messages MUST always be authenticated.
+SCMP informational messages MAY optionally be authenticated; a response message
+MUST be authenticated if and only if the corresponding request message was
+authenticated.
+
+All DRKey keys used here are derived with :ref:`protocol identifier <drkey-protocol-identifiers>` :code:`SCMP`, decimal :code:`1`.
+
+SCMP messages from (and to) routers are authenticated with :ref:`AS-host keys <drkey-as-host>`.
+SCMP response messages from a router in AS :math:`D` to a node :math:`H_s` in
+AS :math:`S` are authenticated with the DRKey :math:`K_{D,S:H_s}`.
+SCMP requests (specifically, :ref:`traceroute-request`) processed by a router
+are authenticated with the same key.
+
+SCMP messages between two end-hosts are authenticated with :ref:`host-host keys <drkey-host-host>`.
+An SCMP response message from a node :math:`H_d` in AS :math:`D` to a node
+:math:`H_s` in AS :math:`S` is authenticated with the key
+:math:`K_{D:H_d,S:H_s}`.
+SCMP requests and data packets from :math:`H_s` to :math:`H_d` are
+authenticated with this same key.
+
+For packets addressed to a router directly (specifically for
+:ref:`echo-request` and :ref:`echo-reply`) it is treated like an end-host and
+the corresponding host-host keys are used.
+
+.. note::
+   Recall that :ref:`traceroute-request`\s are *not* addressed to the router.
+   Instead, the router processes the request if its router alert flag is set.
+
+Processing Rules
+----------------
+The processing rules for SCMP messages are extended with the following points:
+
+-  Every SCMP error message MUST be authenticated.
+
+   Every SCMP informational reply message MUST be authenticated if and only if
+   the corresponding request was authenticated.
+
+   .. note::
+      Consequentially, an implementation without support for SCMP
+      authentication MUST never send SCMP error messages and MUST NOT reply to
+      authenticated SCMP informational request messages.
+
+-  When an SCMP message is received, the receiver MUST check the
+   authentication header.
+
+   - SCMP error messages without or with an invalid authentication header and
+     SCMP informational messages with an invalid authentication header MUST
+     be silently dropped.
+
+   - The receiver checks that the :ref:`DRKey identified by the SPI <spao-spi-drkey>`
+     is appropriate for the SCMP message type and code, as described above in
+     the section :ref:`scmp-spao`.
+
+   - The receiver derives or fetches the relevant key for validation of the MAC.
+
+   - Before checking the authentication, and in particular before fetching a
+     key, the receiver SHOULD check whether the quoted message was possibly
+     recently sent via/to the originator of the error message.
+
+   - The receiver MUST limit the traffic to the control service to fetch keys
+     for verifying the authentication of an SCMP message.
+     At most one packet SHOULD be sent to fetch the key for a received SCMP
+     message. If this fails or is not possible (e.g. because there is no
+     existing TCP session to the control service), the message SHOULD be
+     silently dropped.
+
+Compatibility
+=============
+As SCMP authentication is a new addition, there will be a transition period during which receivers
+may accept SCMP error messages without authentication.
+
+Discussion
+==========
+
+Even though this proposal had been accepted, it later turned out that there is no strong consensus
+to implement this in all routers and end points. For now, this has been put on hold.
+Alternative options that can be considered:
+
+- No authentication, expand the heuristics that end hosts apply to detect fraudulent SCMP messages.
+- Authenticate only :ref:`external-interface-down` and :ref:`internal-connectivity-down` messages.
+  If we authenticate only the information about the link that is down (ISD, AS, interface IDs) and a coarse timestamp, we can reuse the same signed message body for link down notifications for some time period, e.g. a few seconds.
+  Protection against message replay is not a concern for these messages types, as receivers can naturally consider them less and less relevant the longer ago they were created.
+  This allows authenticating these message body with relatively slow asymmetric cryptographic signatures with the CP-PKI, removing the dependency on DRKey.
+  The signature would be part of the SCMP message format for these specific messages and thus no longer requires the SPAO header.
+  Overall, this approach is very similar to the "Path revocation" messages that we historically used to have.

+Running SCION Locally

+
+SCION is an Internet architecture and SCION networks are composed of
+many hosts running the SCION control-plane services, routers, and SCION-enabled
+applications.
+To simplify development, testing, and tinkering, we provide a tool that generates test
+topologies and runs an entire SCION "Internet" on a single machine. Packets are
+only sent between different processes on the same host, not over the network.
+
+Running SCION in this developement setup, is also called running a **local topology**.
+
+The scripts support two different process orchestrators as "backends":
+
+- `supervisor <http://supervisord.org/>`_. This is the default and a bit more light-weight. Packets are sent over the loopback interface.
+- `docker compose <https://docs.docker.com/compose/>`_. Runs individual processes in separate containers connected with docker network bridges. Only this mode supports running a "SCION-IP gateway".

+
+Local Topology Environment
+==========================
+
+The :option:`scion.sh topology` command generates configuration in the ``gen/`` directory in the
+repository.
+
+There is a subdirectory for each AS (e.g. ``gen/ASff00_0_110`` for AS ``ff00:0:110``), containing
+the configuration for the services and routers of that AS.
+Specifically, these contain the :ref:`.toml <common-conf-toml>` configuration files for the individual
+components and a shared :ref:`topology.json <common-conf-topo>` configuration.
+
+Various helper files are also generated for the benefit of scripts and tooling of the test infrastructure,
+for example, ``gen/sciond_addresses.json`` is a simple mapping from AS number to the address of the
+corresponding :doc:`scion daemon </manuals/daemon>` instance.
+
+If  :option:`scion.sh topology -d` command is used, configuration files are created to
+enable running the SCION services in docker containers (see :ref:`docker-section`). Otherwise,
+a configuration file is created to enable running the SCION services as plain processes
+(see :ref:`supervisor-section`)
+
+.. _supervisor-section:
+
+supervisor
+----------
+The ``gen/supervisord.conf`` configuration defines the programs that make up the local topology.
+
+All the SCION traffic goes via the loopback interface, the separation of the internal
+networks of the simulated ASes is not enforced in any way.
+
+There is a single :doc:`/manuals/dispatcher` instance, receiving and sending the SCION packets for
+the :doc:`/manuals/control` instances and SCION applications/tools in all simulated ASes.
+
+There is one :doc:`/manuals/daemon` instance running for each simulated AS.
+Commands accessing the SCION network can be run directly from the host. The information about the
+local AS in which the command is running, is determined by the SCION daemon instance that the
+command connects to.
+For example::
+
+   # show paths from 1-ff00:0:112 to 1-ff00:0:110
+   bin/scion showpaths --sciond $(./scion.sh sciond-addr 112) 1-ff00:0:110
+
+   # reveal the full SCION address of a simulated host in in 1-ff00:0:111
+   bin/scion address --sciond $(./scion.sh sciond-addr 111)
+
+   # and now ping this host from inside AS 1-ff00:0:110, with interactive path prompt
+   bin/scion ping --sciond $(./scion.sh sciond-addr 110) 1-ff00:0:111,127.0.0.1 --interactive
+
+.. _docker-section:
+
+docker
+------
+The main docker compose file is ``gen/scion-dc.yml``.
+
+Each SCION service or router runs in a separate container, and the network access of the individual
+containers is configured to mimick real-world connectivity.
+
+There are "tester" containers configured in each AS to mimick end hosts in a SCION AS.
+These tester containers can be used to run commands accessing the SCION network.
+As a shorthand for the somewhat unwieldy ``docker compose`` invocation, the :file-ref:`tools/dc`
+script can be used. For example::
+
+   # show paths from 1-ff00:0:112 to 1-ff00:0:110
+   tools/dc exec_tester 1-ff00_0_112 bin/scion showpaths 1-ff00:0:110
+
+   # reveal the full SCION address of the tester container in 1-ff00:0:111
+   tools/dc exec_tester 1-ff00_0_111 bin/scion address
+
+   # and now ping this host from inside AS 1-ff00:0:110, with interactive path prompt
+   tools/dc exec_tester 1-ff00_0_110 bin/scion ping 1-ff00:0:111,172.20.0.29
+
+Note that the ``--sciond`` flag does not need to be provided in this setup, as it's preconfigured
+in the tester containers via the environment variable ``SCION_DAEMON``.
+
+scion.sh
+========
+
+:program:`scion.sh` is the developer script to setup and run a local topology.
+
+.. Note::
+   The SCION tools and services need to be built **before** running these commands, using
+   ``make`` or ``make docker-images`` (when using the docker compose configuration).
+
+The basic usage is ``./scion.sh <subcommand> <options>``. The main subcommands are:
+
+.. program:: scion.sh
+
+.. option:: topology
+
+   Generate the control-plane PKI keys and certificates, configuration files,
+   and process orchestrator (supervisor or docker compose) configuration
+   for a given network topopology defined in a
+   :file-ref:`*.topo configuration file <topology/README.md>`.
+
+   .. program:: scion.sh topology
+
+   .. option:: -c <FILE.topo>, --topo-config <FILE.topo>
+
+      Path to the :file-ref:`*.topo configuration file <topology/README.md>`.
+
+   .. option:: -d, --docker
+
+      Create a docker compose configuration (instead of default supervisord).
+
+   .. option:: --sig
+
+      Generate a :doc:`/manuals/gateway` for each AS.
+      Only available with -d.
+
+   .. option:: -h, --help
+
+      Display help text, list all options
+
+.. option:: run, start
+
+   Start the local SCION topology.
+
+.. option:: stop
+
+   Terminate this run of the local SCION topology.
+
+.. option:: start-monitoring
+
+   Start the monitoring services (jaeger and prometheus).
+
+.. option:: stop-monitoring
+
+   Stop the monitoring services.
+
+.. option:: sciond-addr <ISD-AS>
+
+   Return the address for the scion daemon for the matching ISD-AS by consulting
+   ``gen/sciond_addresses.json``.
+   The ISD-AS parameter can be a substring of the full ISD-AS (e.g. last three digits), as long as
+   there is a unique match.
+
+.. option:: help
+
+   Describe all available subcommands
+
+end2end_integration
+===================
+
+:program:`bin/end2end_integration` is a basic functional test.
+
+The basic usage is ``./end2end_integration <options>``.
+
+.. program:: end2end_integration
+
+.. option:: -d
+
+   Assume the SCION services are dockerized. Must be consistent with the last
+   invocation of ``scion.sh topology``.

+
+Setting up the Development Environment
+======================================
+
+.. hint::
+
+   These instructions describe the setup for building and running all integration tests with bazel,
+   docker and various other tools and scripts.
+   See :doc:`build` for instructions focussing only on how to build the SCION executables.
+
+Prerequisites
+-------------
+
+#. Make sure that you are using a clean and recently updated linux distribution. Distributions that are
+   known to work are:
+
+   - **Ubuntu** release 18.04 or later.
+   - **Fedora** release 38 or later.
+   - **Amazon** Linux 2.
+
+   Other Linux environments will usually be fine too, but some of the tooling might need
+   tweaking. If you make things work for other distributions, please update this list.
+
+   This environment assumes you're running as a non-root user with ``sudo`` access.
+#. Install ``docker``.
+   Please follow the instructions for `docker server <https://docs.docker.com/engine/install/#server>`_.
+   Then, add your user to the ``docker`` group:
+   ``sudo usermod -a -G docker ${LOGNAME}``, where ``${LOGNAME}`` is replaced with your user name. Log out
+   and log back in so that your membership of the ``docker`` group is seen by the shell session.
+
+   Optionally install the ``Docker Compose Plugin``. This is needed if you want to run the
+   ``docker compose`` based test topology setup instead of the default setup based on ``supervisord``.
+   Please follow the instructions for
+   `Install Compose Plugin <https://docs.docker.com/compose/install/linux/#install-using-the-repository>`_.
+
+Setup
+-----
+
+#. Clone the SCION repository into your workspace.
+
+   .. code-block:: bash
+
+      git clone https://github.com/scionproto/scion
+      cd scion
+
+#. We use `Bazel <https://bazel.build>`__ for both building and testing. To be
+   able to define the bazel version in the repository we use the `bazelisk
+   <https://github.com/bazelbuild/bazelisk>`__ wrapper around bazel. To set it
+   up simply use::
+
+      ./tools/install_bazel
+
+   and make sure that ``~/.local/bin`` is on your ``PATH``.
+
+   You can also manually install ``bazelisk`` and create an alias so that
+   ``bazel`` will resolve to the ``bazelisk`` command.
+
+#. To install the required build toolchains and scripting dependencies, run:
+
+   .. code-block:: bash
+
+      ./tools/install_deps
+
+#. Start the bazel-remote container.
+
+   We use `bazel-remote <https://github.com/buchgr/bazel-remote>`_ to cache
+   build artifacts from bazel. Bazel-remote can manage the disk space and does
+   not infinitely grow like the Bazel built-in disk-cache. To start bazel-remote run::
+
+      ./scion.sh bazel-remote
+
+#. Build SCION services and tools.
+
+   .. code-block:: bash
+
+      make
+
+   .. hint:: This builds tools for tests in addition to the main SCION services (e.g., ``end2end``);
+      if you don't require those, you can only build the SCION services by running ``make build``.
+      See :doc:`build` for more details.
+
+#. Finally, check that tests run correctly:
+
+   .. code-block:: bash
+
+      make test
+      make test-integration
+
+#. (Optional) If you already have some code you wish to contribute upstream, you can also run the
+   linters locally with:
+
+   .. code-block:: bash
+
+      make lint
+

+Router Benchmark
+****************
+
+:program:`acceptance/router_benchmark/benchmark.py` is a tool to benchmark an external router.
+
+The usage is simply: ``acceptance/router_benchmark/benchmark.py``.
+
+Without any options, the tool outputs instructions. Those instructions comprise how to configure
+the subject router and how to re-execute the tool so it actually carries the measurement.
+
+In order to accomplish the tool's instructions one will need to:
+
+* run two microbenchmarks on the subject router: :program:`coremark` and :program:`mmbm`.
+* configure :program:`scion-router` on the subject router with a custom configuration and topology.
+* configure two of the subject router's interfaces.
+* connect these interfaces to two interfaces of the host where :program:`benchmark.py` is going to
+  run.
+
+If the subject router is an *X86_64* platform running *Openwrt*, then one should install the
+package *scion-bmtools*, which will not only configure :program:`scion-router` for benchmarking,
+but will also run the :program:`coremark` and :program:`mmbm` microbenchmarks and make their
+results available for pickup by :program:`benchmark.py`.
+
+Otherwise these operations still have to be carried out manually. The :program:`mmbm` and
+:program:`coremark` tools can be found in: ``bazel-bin/tools/mmbm/mmbm_/mmbm`` and
+``bazel-bin/tools/coremark/coremark``.

+*******
+Testing
+*******
+
+Basics
+======
+
+* **Run all tests**:
+  To execute the entire test suite in your local :doc:`development environment </dev/setup>`, run
+
+   .. code-block:: sh
+
+      make test               # to run unit-tests
+      make test-integration   # to run integration/"acceptance" tests
+
+   These make targets are a convenient way to invoke the actual build and test tool, ``bazel``.
+   See the :file-ref:`Makefile` for the definition of the targets.
+   The referenced bazel ``--config`` are defined in :file-ref:`.bazelrc`.
+
+* **Unit tests for individual go packages**:
+  To run tests for individual go packages, like for example ``pkg/snet``, invoke ``bazel test``
+  directly and specify the test as a bazel target:
+
+   .. code-block:: sh
+
+      bazel test --config=unit //pkg/snet:go_default_test # unit test for exactly pkg/snet
+      bazel test --config=unit //pkg/snet/...             # unit tests for all packages under pkg/snet
+
+* **Run individual go test cases**:
+  Use the ``--test_filter=<regex>`` option to filter on the level of individual test cases.
+
+   .. code-block:: sh
+
+      bazel test --config=unit //pkg/snet:go_default_test --test_filter=TestPacketSerializeDecodeLoop
+
+* **Useful bazel test flags**: Finding a flag in the `bazel command line reference <https://bazel.build/reference/command-line-reference>`_
+  can be tricky, so here are some pointers:
+
+   * |bazel-nocache_test_results|_: disable the default caching of test results, to force rerunning them.
+   * |bazel-test_output-streamed|_: show all test output
+   * |bazel-test_arg|_: Pass flags to the `go testing infrastructure <https://pkg.go.dev/cmd/go#hdr-Testing_flags>`_.
+
+     For example, instead of the ``--test_filter=<regex>`` mentioned above we could also filter
+     tests with ``--test_arg=-test.run=<regex>``.
+     This can be used to run benchmarks.
+
+.. |bazel-nocache_test_results| replace:: ``--nocache_test_results`` / ``-t-``
+.. _bazel-nocache_test_results: https://bazel.build/reference/command-line-reference#flag--cache_test_results

+*********
+Wireshark
+*********
+
+To inspect SCION packets that are sent over the wire it can be helpful to use
+Wireshark.
+For this, we have a Wireshark SCION packet dissector plugin, :download:`scion.lua </../tools/wireshark/scion.lua>`.
+
+Install Wireshark
+^^^^^^^^^^^^^^^^^
+
+Wireshark is available from the standard package repositories in most OS distributions (:command:`apt`, :command:`yum`, :command:`pacman`, etc).
+More details, and installers for Windows and MacOS, can be found on the
+`Wireshark download page <https://www.wireshark.org/download.html>`_.
+
+
+.. Note::
+
+   The scion.lua plugin requires version 3.x of Wireshark, which is not shipped
+   by default on older versions of Ubuntu, like 18.04. Use ``ppa:wireshark-dev/stable``
+   to install a more recent version:
+
+   .. code-block:: bash
+
+      sudo add-apt-repository ppa:wireshark-dev/stable
+      sudo apt-get update
+      sudo apt-get install wireshark
+
+
+Install the SCION packet dissector plugin
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Store the :download:`scion.lua </../tools/wireshark/scion.lua>` plugin file to
+the `Wireshark plugin folder <https://www.wireshark.org/docs/wsug_html_chunked/ChPluginFolders.html>`_.
+This folder needs to be created if it doesn't exist.
+
+- ``$HOME/.config/wireshark/plugins`` for most Linux distributions
+- Windows:  ``%APPDATA%\Wireshark\plugins``
+- MacOS:    ``/Applications/Wireshark.app/Contents/PlugIns/wireshark``
+
+
+In the Wireshark GUI, the dialog :guilabel:`Analyze`:menuselection:`-->`:guilabel:`Enabled Protocols`
+should now list multiple protocols related to SCION.
+
+After that you can test it by running a topology and using a SCION filter, for
+example::
+
+    scion.dst_as == "ff00:0:110"
+
+.. Note::
+
+   The :command:`tshark` command-line frontend for Wireshark lists the installed plugins with::
+
+      tshark -G plugins
+
+Work remotely with Wireshark
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Sometimes it can be handy to use the remote feature of wireshark to tap into an
+interface on a different machine.
+
+
+#. Install wireshark on your local OS and install the dissector plugin (see above)
+
+#. Prepare the remote machine
+
+   Install tcpdump::
+
+      sudo apt-get install tcpdump
+
+   The user used to SSH into the remote machine needs to have full access to tcpdump.
+   Hence create a new group and add this user to the group. SSH into the remote machine
+   and execute::
+
+      sudo groupadd pcap
+      sudo usermod -a -G pcap $USER
+
+   set this group as the owner of tcpdump::
+
+      sudo chgrp pcap /usr/sbin/tcpdump
+      sudo chmod 750 /usr/sbin/tcpdump
+
+   give tcpdump the necessary permissions::
+
+      sudo setcap cap_net_raw,cap_net_admin=eip /usr/sbin/tcpdump
+
+   .. note::
+      This will allow every user part of the pcap group to use the full
+      capabilities of tcpdump!
+
+#. Figure out the network interface on the remote host you want to tap into:
+   Get an IP address used by the SCION topology that's probably running with docker.
+   Search for the network-interface that's with the corresponding subnet.
+
+#. Start wireshark and click on the gear next to the interface named
+   "SSH remote capture: sshdump".
+   Fill in the IP address and Port of the remote host, as well as your preferred
+   authentication method in the Authentication tab.
+   At the Capture tab write the name of the interface you found in the previous
+   step. Find the a screenshot of an example below:
+
+   .. image:: wireshark.png
+
+#. Now you are ready to click start and investigate some SCION traffic

+
+   AS
+   Autonomous System
+
+      An autonomous system is a computer network controlled by a single entity, typically an
+      Internet-service provider or a larger organization like a university, participating in the
+      Internet routing.
+      In the traditional BGP-based Internet, ASes are assigned 32-bit autonomous system numbers (ASN).
+      The AS identifiers in SCION are longer, 48-bit, and usually occur in combination with the
+      identifier for a specific :term:`ISD` in which the AS is being identified.
+
+      In SCION, the concept of ASes takes a more prominent role as it also serves as "locator" in
+      the addressing of end hosts.
+
+   BFD
+   Bidirectional Forwarding Detection
+
+      Bidirectional Forwarding Detection (BFD) is a network protocol that is used to
+      detect faults between two forwarding engines connected by a link.
+      See :rfc:`5880` and :rfc:`5881`.
+
+      In SCION, BFD is used to determine the liveness of the link between two border routers
+      and trigger :term:`SCMP` error messages.
+
+   CA
+   Certificate Authority
+
+      An entity that signs and issues digital certificates, certifying the ownership of a public
+      key by the named subject of the certificate.
+      CAs are a part of a public key infrastructure, like the SCION :term:`Control-Plane PKI`.
+
+   CP-PKI
+   Control-Plane PKI
+
+      The SCION Control-Plane Public Key Infrastructure (PKI) defines the certificate hierarchy that
+      allows to tie cryptographic keys to SCION AS identifiers.
+      This is the machinery that allows to authenticate SCION control-plane messages.
+
+      See :doc:`/cryptography/index`.
+
+   End Host
+   Endpoint
+      A SCION **end host** is a computer or other device connected to a computer network in a
+      SCION AS, able to send and receive SCION traffic.
+
+      In the `IRTF PANRG's vocabulary of path properties <https://datatracker.ietf.org/doc/draft-irtf-panrg-path-properties/>`_,
+      **endpoints** are the start and end node of a path.
+      An endpoint can be an end host, but it applies slightly more generically to any node which is
+      the source or destination of SCION traffic, e.g. to a gateway.
+
+      The terms "endpoint" and "end host" are used mostly interchangeably.
+      End host is preferred where the focus is (physical or virtual) machines and the software
+      running on them, and endpoint is used otherwise.
+
+   Interface ID
+      An interface ID is the AS-local identifier for an inter-domain link.
+
+      The interface ID is an arbitrary 16-bit number between 1 and 65535,
+      assigned without external coordination by the operator of the AS.
+
+   ISD
+   Isolation Domain
+
+      An Isolation Domain (ISD) is a set of participating :term:`ASes <AS>`.
+      ISDs can overlap, i.e. ASes can participate in multiple ISDs.
+
+      An ISD represents a scope for :term:`CAs <CA>` in the :term:`Control-Plane PKI`;
+      CAs can issue certificates exclusively to ASes in their ISD.
+
+      At the same time Isolation Domains also serve as a local routing domain.
+      Inside an isolation domain, links between ASes form a directed acyclic graph, allowing
+      efficient path discovery.
+      Only the core ASes (i.e. the ASes at the top(s) of this directed acyclic graph) need to
+      participate in the less efficient inter-ISD path discovery.
+
+      See :ref:`overview-isds`.
+
+   Beacon
+   PCB
+   Path-Segment Construction Beacon
+
+      Path-Segment Construction Beacons are control-plane messages that are propagated through a
+      SCION network during the :ref:`path exploration ("beaconing") <control-plane-beaconing>` process.
+      On their way, PCBs accumulate authenticated network topology information (on the granularity
+      of :term:`ASes <AS>`).
+
+   SCMP
+   SCION Control Message Protocol
+
+      The SCION analog to `ICMP <https://en.wikipedia.org/wiki/Internet_Control_Message_Protocol>`_.
+
+      A supporting protocol for the SCION dataplane. It is used by SCION routers or end hosts to
+      send error messages and for diagnostics (ping and traceroute).
+
+      See :doc:`/protocols/scmp` for more information.
+
+   TRC
+   Trust-Root Configuration
+
+      Each :term:`ISD` has a separate trust-root configuration, specifying the core ASes acting as
+      :term:`CAs <CA>`.
+
+      See :doc:`/cryptography/trc`.

+Configuration
+*************
+
+The general pattern for the long-running SCION services (:doc:`router`, :doc:`control`,
+:doc:`gateway`, :doc:`daemon`), is to load a :ref:`.toml <common-conf-toml>` configuration file
+which is specified with a ``--config`` option when starting the service.
+This configuration file specifies all options for running the service, in particular the
+**configuration directory** from which all other configuration files are read.
+
+The set of required configuration files differs between the applications. The configuration files
+are organized specifically to allow sharing the configuration directory between different services.
+
+.. _common-conf-toml:
+
+Configuration .toml
+===================
+
+This configuration is a `TOML <https://toml.io/en/>`_-file.
+
+The following options are implemented by all applications.
+
+.. program:: common-conf-toml
+
+.. object:: log
+
+   .. option:: log.console.level = "debug"|"info"|"error" (Default: "info")
+
+      Log level at startup.
+
+      The log level can be changed at runtime via the :ref:`HTTP API <common-http-api>`.
+
+   .. option:: log.console.format = "human"|"json" (Default: "human")
+
+      Encode the log either in a human oriented form or json.
+
+   .. option:: log.console.disable_caller = <boolean>
+
+      If ``true``, disable annotating logs with the calling function's file name and line number.
+      By default, all logs are annotated.
+
+
+.. object:: metrics
+
+   .. option:: metrics.prometheus = <string>
+
+      Address on which to export the :ref:`common HTTP API <common-http-api>`, in the form
+      ``host:port``, ``ip:port`` or ``:port``.
+      The eponymous prometheus metrics can be found under ``/metrics``, but other endpoints
+      are always exposed as well.

+Database Connections
+--------------------
+
+The services use different SQLite database files, with paths and advanced connection options
+configured individually.
+The pattern is:
+
+.. object:: some_db
+
+   .. option:: some_db.connection = <string>
+
+      File path or `SQLite URI <https://www.sqlite.org/uri.html>`_ for SQLite database.
+
+   .. option:: some_db.max_open_conns = <int> (Default: 1)
+
+      Sets sets the maximum number of open connections to the database.
+
+      This **should** be left at 1 for SQLite databases.
+
+   .. option:: some_db.max_idle_conns = <int> (Default: 2)
+
+      Sets the maximum number of connections in the idle connection pool.
+      If this value is higher than :option:`max_open_conns <common-conf-toml some_db.max_open_conns>`,
+      then the effective value is the same as :option:`max_open_conns <common-conf-toml some_db.max_open_conns>`.
+
+      This **should** be left > 0 for SQLite databases, in particular
+      if an `in-memory database <https://www.sqlite.org/inmemorydb.html>`_ is used.
+
+.. _common-conf-topo:
+
+topology.json
+=============
+
+The ``topology.json`` file of an AS specifies all the inter-AS connections to neighboring ASes, and
+defines the underlay IP/UDP addresses of services and routers running in this AS.
+The topology information is needed by :doc:`router` and :doc:`control` instances, and also by
+end-host applications (including the :doc:`gateway`) which usually obtain it indirectly from the
+:doc:`daemon` running on the same host.
+
+.. Note::
+
+   The topology.json configuration file contains information that is not relevant for all consumers
+   of the file.
+
+   For the sake of simplicity, you can use the same topology.json file on all SCION components
+   within the SCION AS. In more advanced configurations, an extract of the topology.json file can be
+   presented to each specific component.
+
+The structure of the configuration is presented as a pseudo-JSON with a more detailed explanation
+of the individual fields below.
+
+..
+   Comment: use YAML syntax highlighting for JSON because this allows annotation comments and
+   accidentally gives pretty nice coloring for placeholders.

+
+   Role of this AS. ``["core"]`` for core ASes, ``[]`` for non-core ASes.
+

+   .. object:: interfaces
+
+      .. option:: <interface-id>
+
+         The :term:`interface ID <Interface ID>` for an inter-domain link.

+      .. option:: remote_interface_id = <int>
+
+         The :term:`interface ID <Interface ID>` for the corresponding interface in the

+
+         This is required if, and only if, :option:`link_to <topology-json link_to>` is ``peer``.
+
+         This ``remote_interface_id`` is used when announcing peering links as part of AS Entries in
+         PCBs (see :ref:`control-plane-beaconing`).
+         During :ref:`path-segment combination <control-plane-segment-combination>`, this interface
+         ID, will then be used together with the ISD-AS to match up the peering entries from

+
+         If ``remote_interface_id`` is set incorrectly, the peering entries cannot be matched up
+         correctly, resulting in missing or broken end-to-end paths:
+
+         - If the ``remote_interface_id`` does not match `any` interface ID used for peering links
+           in the neighboring AS, the segment combination will not find paths making use of this
+           interface.
+         - If two ASes are connected by multiple peering links and ``remote_interface_id`` matches the
+           `wrong` interface ID, an incorrect path may be constructed which will be rejected in the
+           data plane (i.e. the routers will drop all packets).

+
+            The IP/UDP address of this router interface.
+            The IP or hostname can be ommitted; in this case the router will just bind to a wildcard
+            address.
+

 Control Service
 ***************
 
+:program:`control` is the SCION control service.
+It discovers SCION paths by participating in the inter-domain path-dissemination process called
+"beaconing".
+It signs and validates the path information based on the :term:`Control-Plane PKI <CP-PKI>`.
+
+The :program:`control` service is also the recursive resolver for path information for endpoints in
+the local AS.
+
+In ASes with the :ref:`CA role<overview-as-roles>`, the :program:`control` service also acts as the
+certificate authority from which ASes in the local ISD request renewed certificates (or as a proxy
+thereof).
+
+See :doc:`/control-plane` for an introduction to the SCION control plane and the tasks of the
+:program:`control` service.
+
+Command line reference
+======================
+
+.. program:: control
+

+
+.. _control-envvars:
+
+Environment variables
+---------------------
+
+.. envvar:: SCION_TESTING_DRKEY_EPOCH_DURATION
+
+   For **testing only**.
+
+   Override the global duration for :doc:`/cryptography/drkey` epochs.
+   This can only work correctly if the same value is set for all connected control services in the
+   test network.
+
+   Also applies to the :ref:`router <router-envvars>`.
+
+   :Type: :ref:`duration <common-conf-duration>`
+   :Default: ``24h``
+
+Configuration
+=============
+
+The :program:`control` service is configured with multiple files:
+
+- the :ref:`.toml <control-conf-toml>` file,
+  specified on the command line by the :option:`--config <control --config>` option, is the main
+  configuration file.
+  It configures common features like logging and metrics and
+  specifies the **configuration directory** from which all other configuration files are read.
+- :ref:`topology.json <control-conf-topo>`, contains information about the inter-AS links
+- :ref:`beaconing policy <control-conf-beacon-policies>` configuration files
+- :ref:`crypto/ and certs/ <control-conf-cppki>` contain :term:`CP-PKI` certificates and private keys
+- :ref:`keys/ <control-conf-keys>` contains the AS's forwarding secret keys
+- :ref:`staticInfoConfig.json <control-conf-path-metadata>`, if it exists, specifies values for the :doc:`/beacon-metadata`.
+
+.. _control-conf-toml:
+
+Control service configuration
+-----------------------------
+
+In addition to the :ref:`common .toml configuration options <common-conf-toml>`, the control service
+considers the following options.
+
+.. program:: control-conf-toml
+
+.. object:: general
+
+   .. option:: general.id = <string> (Required)
+
+      An identifier for this control service.
+
+      This is used to identify which parts of the :ref:`control-conf-topo` file are refering to self.
+      Thus, ``id`` must match a key in the :ref:`control-conf-topo` files' ``control_service`` section.
+
+   .. option:: general.config_dir = <string> (Required)
+
+      Path to a directory containing the remaining configuration files.
+
+      If this is a relative path, it is interpreted as relative to the current working directory of the
+      program (i.e. **not** relative to the location of this .toml configuration file).
+
+   .. option:: general.reconnect_to_dispatcher = <bool> (Default: false)
+
+      Transparently reconnect to the dispatcher on dispatcher failure or restarts.
+
+      .. Warning::
+         This should be set to ``true``, unless your service orchestration ensures that
+         failures of the dispatcher also trigger a restart of :program:`control`.
+
+.. object:: features
+
+   Features is a container for generic, boolean feature flags (usually for experimental or
+   transitional features).
+
+   .. option:: features.appropriate_digest_algorithm = <bool> (Default: false)
+
+      Enables the CA module to sign issued certificates
+      with the appropriate digest algorithm instead of always using ECDSAWithSHA512.
+
+      **Transition**: This behaviour should be enabled unless there is a specific requirement to
+      interface with older versions of SCION that don't support these certificates.
+      The default for this flag will be changed to ``true`` in future releases, and the flag will
+      eventually be removed.
+
+.. object:: api
+
+   .. option:: api.addr = <string> (Optional)
+
+      Address at which to expose the :ref:`control-rest-api`,
+      in the form ``host:port``, ``ip:port`` or ``:port``.
+
+.. object:: tracing
+
+   Tracing with `OpenTracing <https://opentracing.io/>`_ / `Jaeger <https://www.jaegertracing.io/>`_.
+   This is especially helpful when collecting the traces of multiple service instances, e.g. when
+   :doc:`running a local SCION topology </dev/run>`.
+
+   .. option:: tracing.enabled = <bool> (Default = false)
+
+   .. option:: tracing.debug = <bool> (Default = false)
+
+   .. option:: tracing.agent = <string> (Default = "localhost:6831")
+
+      Address of the local agent that handles the reported traces.
+
+.. object:: quic
+
+   .. option:: quic.address = <ip:port> (Optional)
+
+      Local SCION address for inter-AS communication by QUIC/gRPC.
+      By default, the address used is that specified for this control service in its ``control_service`` entry of
+      the :ref:`control-conf-topo`.
+
+.. object:: beaconing
+
+   .. option:: beaconing.origination_interval = <duration> (Default = "5s")
+
+      Specifies the interval between originating beacons in a core AS.
+
+   .. option:: beaconing.propagation_interval = <duration> (Default = "5s")
+
+      Specifies the interval between propagating beacons.
+
+   .. option:: beaconing.registration_interval = <duration> (Default = "5s")
+
+      Specifies the interval between registering path segments.
+
+   .. option:: beaconing.policies
+
+      File paths for :ref:`control-conf-beacon-policies`.
+      If these are the empty string, the default policy is used.
+
+      The different policies *may* point to the same file(s).
+
+      .. option:: beaconing.policies.propagation = <string>
+      .. option:: beaconing.policies.core_registration = <string>
+      .. option:: beaconing.policies.up_registration = <string>
+      .. option:: beaconing.policies.down_registration = <string>
+
+
+   .. option:: beaconing.epic = <bool> (Default: false)
+
+      Specifies whether the EPIC authenticators should be added to the beacons.
+
+.. object:: path
+
+   .. option:: path.query_interval = <duration> (Default = "5m")
+
+      Specifies after how much time path segments for a destination AS should be refetched.
+
+   .. option:: path.hidden_paths_cfg = <string> (Optional)
+
+      Location of the :doc:`hidden paths </hidden-paths>` configuration.
+
+      The location is specified as a file path (relative to the working directory of the program)
+      or an HTTP/HTTPS URL.
+
+.. object:: ca
+
+   .. option:: ca.mode = "disabled"|"in-process"|"delegating" (Default: "disabled")
+
+      Mode defines whether the :program:`control` should handle certificate issuance requests.
+      This should be enabled in core ASes that are labeled as ``issuing`` ASes in the :term:`TRC`.
+
+      If set to ``in-process``, :program:`control` handles certificate issuance requests on its own.
+      If set to ``delegating``, the certificate issuance is delegated to the service defined in
+      :option:`ca.service <control-conf-toml ca.service>`.
+
+   .. option:: ca.max_as_validity = <duration> (Default: "3d")
+
+         Defines the the maximum lifetime for renewed AS certificates.
+
+   .. option:: ca.service
+
+      Configuration for the :term:`CA` service,
+      effective with the :option:`ca.mode <control-conf-toml ca.mode>` mode ``delegating``.
+
+      The CA service is expected to implement the API described by :file-ref:`spec/ca.gen.yml`.
+
+      .. Hint::
+         The `scionproto/scion <https://github.com/scionproto/scion>`_ project does not include such
+         a standalone CA service implementation.
+
+         The available options are:
+
+         - use the built-in CA implementation (using :option:`ca.mode = "in-process" <control-conf-toml ca.mode>`),
+         - use the `netsys-lab/scion-ca <https://github.com/netsys-lab/scion-ca>`_ SCION CA
+           based on `smallstep's step-ca <https://github.com/smallstep/certificates>`_,
+         - ask SCION vendors for proprietary CA implementations and offerings,
+         - plug in your own CA service implementing the :file-ref:`spec/ca.gen.yml` API.
+

+The entry referring to its own :option:`general.id <control-conf-toml general.id>`
+define the addresses that :program:`control` will listen on.
+
+The interface definitions in the ``border_router`` entries define the inter-AS links.
+These entries define the beacons that :program:`control` will originate and propagate.
+
+.. _control-conf-beacon-policies:
+
+Beaconing policies
+------------------
+
+A beaconing policy is a YAML file, defining processing rules for path-segment construction and
+registration.
+There are four policies with different but related purposes, that can individually be configured
+with the :option:`beacon.policies <control-conf-toml beaconing.policies>` options:
+
+Propagation
+   Propagation is the process of receiving a beacon from a neighbor AS, extending it
+   with one's own AS entry and forwarding it to downstream neighbor ASes.
+   See :ref:`control-plane-beaconing`.
+
+   The propagation policy determines which beacons are selected to be propagated and how they are
+   extended.
+
+   Note that there is no separate policy type for beacon origination. The only policy value
+   affecting origination is the :option:`MaxExpTime <control-conf-beacon-policy MaxExpTime>`, which is
+   read from the propagation policy.
+
+Registration
+   Registration is the process of making beacons available as path-segments to the path lookup
+   process.
+   Beacons received from a neighbor AS are "terminated" by appending the own AS entry and registered
+   in a path-segment database, from which it can be later found with path-segment queries.
+   See :ref:`control-plane-registration`.
+
+   CoreRegistration
+      Applies to the registration of core-segments in the local path store of a core AS.
+
+   UpRegistration
+      Applies to the registration of up-segments in the local path store of a non-core AS.
+
+   DownRegistration
+      Applies to the registration of down-segments. The policy is used by a non-core AS
+      to determine which down-segments it wants to make available to other ASes.
+      Each selected down-segments is registered, via a segment registration request, in the core AS
+      that originated it.
+
+      .. note::
+         There is currently no corresponding policy that applies to the processing of segment
+         registration requests in the core AS.
+
+From the description above, it is already evident that not all four policies are applicable for
+core and non-core ASes. Summarizing this:
+
+.. table::
+
+   ================= ================================================
+   AS type           Applicable policies
+   ================= ================================================
+   core              Propagation, CoreRegistration
+   non-core          Propagation, UpRegistration, DownRegistration
+   ================= ================================================
+
+
+The beaconing policy YAML configuration considers the following options:
+
+.. program:: control-conf-beacon-policy
+
+.. option:: Type = "Propagation"|"UpSegmentRegistration"|"DownSegmentRegistration"|"CoreSegmentRegistration" (Default: "")
+
+   Restrict this policy configuration file to be used exclusively as one of the
+   :option:`beacon.policies <control-conf-toml beaconing.policies>` options.
+
+   Only as sanity check and organization of configuration files. No operational effect.
+
+.. option:: BestSetSize = int (Default: 20)
+
+   Maximum number of segments to propagate/register **per origin AS**.
+
+   In the ``Propagation`` policy, this parameter determines the number of beacons
+   propagated to neighbor ASes per origin AS.
+   That is, for each originating AS, up to ``BestSetSize`` beacons are forwarded.
+   For the core-beaconing process, the set of originating ASes are all other core ASes, which can
+   be very numerous.
+
+   .. warning::
+
+      Keep this parameter reasonably low to avoid an explosion of beacon numbers.
+
+.. option:: CandidateSetSize = int (Default: 100)
+
+   Maximum number of segments to keep in beacon store and consider for selection to best set **per
+   origin AS**.
+
+.. option:: MaxExpTime = uint8 (Default: 63)
+
+   Defines the maximum relative expiration time for the AS Entry when originating, propagating or
+   terminating a PCB.
+
+   .. note::
+      For beacon origination, the ``MaxExpTime`` value from the ``Propagation`` policy is used.
+
+   The 8 bit unsigned integer :ref:`ExpTime <scion-path-exptime>` fields represents an expiration
+   relative to the origination timestamp of the segment, with a nonzero minimum and a maximum
+   of 24 hours:
+
+   .. math::
+        (1 + ExpTime) \cdot \frac{24\cdot60\cdot60}{256}\mathrm{s}
+
+   Every increment of `ExpTime` represents 5 minute and 37.5 seconds in duration.
+
+   ============= ================
+   ``ExpTime``   Duration (h:m:s)
+   ============= ================
+   0             0:05:37.5
+   1             0:11:15
+   2             0:16:52.5
+   ...           ...
+   9             0:56:15
+   10            1:01:52.5
+   11            1:07:30
+   ...           ...
+   63            6:00:00
+   ...           ...
+   254           23:54:22.5
+   255           24:00:00
+   ============= ================
+
+.. option:: Filter
+
+   Filters restrict the allowed beacons for the purposes of the policy (i.e. for propagation or
+   the different forms of registration).
+
+   Filters are applied when a beacon is received, resulting in a "usage" classification of the
+   beacon that is stored in the local beacon database.
+   Therefore, when the policy is changed, it will only be effective for newly received beacons.
+
+   .. note::
+
+      Filters are currently not very expressive. Specifically, they cannot express filtering rules
+      that take into account the ingress or egress interface of the beacon.
+
+      There are plans to extend this functionality but so far there are no concrete proposals.
+      If you're interested in working on this, get in contact in the :ref:`chat <slack>` or create a
+      :ref:`proposal <change-proposal-process>` on github.
+
+   .. option:: MaxHopsLength = <int>
+
+      Upper bound for the allowed number of AS entries in a received PCB.
+
+      Filters are applied for received PCBs, before extending the segment.
+      Consequently, a propagated/terminated PCB may have up to ``MaxHopsLength + 1`` AS entries.
+
+   .. option:: AsBlackList = <List[AS identifier]>
+
+      Deny-list for ASes.
+      PCBs with any AS entry from any of the specified AS identifiers will be rejected.
+
+   .. option:: IsdBlackList = <List[ISD identifier]>
+
+      Deny-list for ISDs.
+      PCBs with any AS entry from any of the specified ISD identifiers will be rejected.
+
+   .. option:: AllowIsdLoop = <bool> (Default: true)
+
+      Specifies whether ISD loops are allowed.
+
+      A PCB is considered to be an ISD loop if it leaves and then re-enters an ISD.
+
+.. _control-conf-cppki:
+
+Control-Plane PKI
+-----------------
+
+TRCs
+   :option:`<config_dir>/certs <control-conf-toml general.config_dir>`
+
+   The :term:`TRC`\s for the :term:`Control-Plane PKI` are loaded from here.
+   TRCs are also written back to the :option:`trust_db <control-conf-toml trust_db>`.
+
+   Any TRC loaded from this directory will be written back to the trust_db.
+   Updated TRCs fetched from authoritative core ASes are stored both here in the filesystem and
+   in the trust_db.
+
+   :program:`control` scans this directory for new TRCs at startup, and also when requesting signing
+   keys and the corresponding certificate chains.
+
+   .. note::
+      :program:`control` does **not** create TRCs.
+      TRC creation is an offline process, the :doc:`/cryptography/trc-signing-ceremony`.
+
+      However, the :program:`control` does fetch new TRCs from neighbor ASes and store them into
+      this directory (<config_dir>/certs).
+
+
+AS Certificates and Keys
+   :option:`<config_dir>/crypto/as <control-conf-toml general.config_dir>`
+
+   :ref:`AS certificate chains <cp-as-certificate>` and the corresponding keys,
+   used for signing control-plane messages and authenticating TLS sessions to other control
+   services, are loaded from here.
+   Certificates are also written back to the :option:`trust_db <control-conf-toml trust_db>` (but
+   keys are not).
+
+   :program:`control` scans this directory for new certificates at startup, and also when loading
+   keys on demand.
+
+   Keys are loaded from this directory on demand, with an in-memory cache with a lifetime of 5
+   seconds.
+
+   .. note::
+      :program:`control` does **not** request renewal of its AS certificates.
+
+      Certificate renewal can be requested using the :ref:`scion-pki_certificate_renew` tool.
+      Because AS certificates have short lifetimes, this *should* be automated by the operator.
+
+CA Certificates and Keys
+   :option:`<config_dir>/crypto/ca <control-conf-toml general.config_dir>`
+
+   If the in-process :term:`CA` is used, :option:`ca.mode = "in-process" <control-conf-toml ca.mode>`,
+   the :ref:`CA certificates <cp-ca-certificate>` and corresponding keys are read from this
+   directory on demand, whenever a certificate renewal request is handled.
+
+   .. note::
+      Even if it is operating with active CA mode,
+      :program:`control` does **not** issue initial certificates for new ASes.
+      Issuance of initial AS certificates is an offline process. See :ref:`ca-ops-as-certs`.
+
+The control service is not directly involved in the creation of TRCs and consequently it is not
+concerned with voting certificates.
+
+.. _control-conf-keys:
+
+Keys
+----
+
+:program:`control` loads the forwarding secret keys ``master0.key``/``master1.key`` from :option:`<config_dir>/keys <control-conf-toml general.config_dir>`.
+
+The key files contain a base64-encoded high-entropy random string.
+The keys should be exactly 16 bytes long (corresponding to a base64 encoding of 24 bytes with two trailing pad bytes ``==``).
+These keys must be identical to the :ref:`corresponding keys used by the routers <router-conf-keys>`.
+
+.. note::
+   The :program:`router` and :doc:`control` currently use these keys as input for PBKDF2 to generate
+   the actual forwarding key. Consequently, keys of any size can currently be used. This may be changed
+   to only accept high-entropy 16 byte keys directly in the future.
+
+.. _control-conf-path-metadata:
+
+Path Metadata
+-------------
+
+The ``StaticInfoExtension`` PCB extension allows to announce :doc:`path metadata in beacons </beacon-metadata>`.
+
+:program:`control` loads the information for the ``StaticInfoExtension``
+for its AS entries from the optional JSON configuration file
+:option:`<config_dir>/staticInfoConfig.json <control-conf-toml general.config_dir>` if it exists.
+
+This configuration is **optional**.
+If the file does not exist, or if the configuration does not specify values for certain metadata
+types or for certain interfaces, the corresponding ``StaticInfoExtension`` will either be omitted or
+include only partial metadata.
+
+If the configuration file exists, it must be syntactically valid.
+
+The structure of the configuration is presented as pseudo-JSON with a more detailed explanation
+of the individual fields below.
+
+.. code-block:: yaml

+
+.. note::
+
+   There is currently no apt repository from which the packages can be installed directly.
+
+.. hint::
+
+   **Systemd**
+
+   The packages include systemd units which can be used to run the SCION components.
+   There are various introduction documents on how to interact with systemd, for example
+   https://wiki.archlinux.org/title/Systemd#Using_units, or https://linuxhandbook.com/systemctl-commands/.
+
+   Very briefly:
+
+   * ``systemctl start <unit>`` / ``systemctl stop <unit>``: start/stop a unit immediately
+   * ``systemctl enable <unit>`` / ``systemctl disable <unit>``: enable/disable a unit to start automatically at boot
+   * ``systemctl status <unit>``: display the status of a unit

+.. envvar:: GOMAXPROCS
+
+   Specified by the GO runtime. The Go runtime starts a number kernel threads such that the number

+   number of cores in the host. That value can be changed via the ``GOMAXPROCS`` environment
+   variable (or programatically by the application code). See
+   `the go runtime documentation <https://pkg.go.dev/runtime#hdr-Environment_Variables>`_
+   for more information. One reason to change this is running multiple routers on the same host.
+   In such a case, it is best to split the available cores among the routers, lest Go's default
+   assumptions causes them to compete for cores and incurr futile context switching. This precaution
+   is especially useful in performance testing situations.
+
+   :Type: unsigned integer
+   :Default: ``all cores``
+
+Configuration
+=============
+
+The :program:`router` is configured by two main files.
+First, the :ref:`.toml <router-conf-toml>` configures common features like logging and metrics and
+specifies the **configuration directory** from which all other configuration files are read.
+The second one is :ref:`topology.json <router-conf-topo>`, which contains all the AS information
+that the router uses to forward packets.
+
+.. _router-conf-toml:
+
+Router Configuration
+--------------------
+
+In addition to the :ref:`common .toml configuration options <common-conf-toml>`, the router
+considers the following options.
+
+.. program:: router-conf-toml
+
+.. object:: general
+
+   .. option:: general.id = <string> (Required)
+
+      Identifier for this router.
+
+      This is used to identify which parts of the :ref:`router-conf-topo` file refer to self.
+      Thus, ``id`` must match a key in the :ref:`router-conf-topo` files' ``border_routers`` section.
+
+   .. option:: general.config_dir = <string> (Required)
+
+      Path to a directory for loading AS :ref:`topology.json <router-conf-topo>` and :ref:`keys
+      <router-conf-keys>`.
+
+      If this is a relative path, it is interpreted as relative to the current working directory of the
+      program (i.e. **not** relative to the location of this .toml configuration file).
+
+.. object:: features
+
+   Features is a container for generic, boolean feature flags (usually for experimental or
+   transitional features).
+
+   .. option:: features.experimental_scmp_authentication = <bool> (Default: false)
+
+      Enable the :doc:`DRKey-based authentication of SCMPs </dev/design/scmp-authentication>` in the
+      router, which is **experimental** and currently **incomplete**.
+
+      When enabled, the router inserts the :ref:`authenticator-option` for SCMP messages.
+      For now, the MAC is computed based on a dummy key, and consequently is not practically useful.
+
+.. object:: router
+
+   .. option:: router.receive_buffer_size = <int> (Default: 0)
+
+      The receive buffer size in bytes. 0 means use system default.
+
+   .. option:: router.send_buffer_size = <int> (Default: 0)
+
+      The send buffer size in bytes. 0 means use system default.
+
+   .. option:: router.num_processors = <int> (Default: GOMAXPROCS)
+
+      Number of goroutines started for SCION packets processing.
+
+      These goroutines make the routing decision for the SCION packets by inspecting, validating and
+      updating the path information in the packet header. Packets are processed asynchronously from the
+      corresponding read/write operations on the individual interface sockets.
+
+      `Goroutines <https://en.wikipedia.org/wiki/Go_(programming_language)#Concurrency:_goroutines_and_channels>`_
+      are the Go programming language's light-weight user-space concurrency primitives. Go's runtime
+      schedules goroutines on top of a smaller number of kernel threads. The default is to use as
+      many packet processors as there are kernel threads started by Go, letting other goroutines
+      displace them sporadically. Whether more or fewer processors are preferable is to be determined
+      experimentaly.
+
+      The number of kernel threads that go creates depends on the number of usable cores, which is
+      controlled by the environment variable ``GOMAXPROCS``. See :envvar:`GOMAXPROCS`.
+
+   .. option:: router.num_slow_processors = <int> (Default: 1)
+
+      Number of goroutines started for the slow-path processing which includes all SCMP traffic and
+      traceroutes. A minimum of 1 slow-path processor is required.
+
+   .. option:: router.batch_size = <int> (Default: 256)
+
+      The batch size used by the receiver and forwarder to
+      read or write from / to the network socket.
+
+   .. object:: bfd
+
+      .. option:: disable = <bool> (Default: false)
+
+         Set whether the :term:`BFD` feature is disabled by default.
+
+         This setting applies to BFD sessions to all neighboring routers, including sibling routers
+         (other routers in the same AS).
+
+         Can be overridden for specific inter-AS BFD
+         sessions with :option:`bfd.disable <topology-json disable>`.
+
+      .. option:: detect_mult = <uint8>, default 3
+
+         Set the :term:`BFD` detection time multiplier.
+
+         After ``detect_mult`` consecutively missing control packets, the BFD session is
+         considered "down" and is reset.
+
+         Can be overridden for specific inter-AS BFD sessions with
+         :option:`bfd.detect_mult <topology-json detect_mult>`.
+
+      .. option:: desired_min_tx_interval = <duration>, default 200ms
+
+         Defines the frequency at which this router should send :term:`BFD` control messages.
+         The effective interval is the result of negotiating with the remote router during
+         session establishment;
+         the value will be ``max(desired_min_tx_interval, remote.required_min_rx_interval)``.
+
+         Can be overridden for specific inter-AS BFD sessions with
+         :option:`bfd.desired_min_tx_interval <topology-json desired_min_tx_interval>`.
+
+      .. option:: required_min_rx_interval = <duration>, default 200ms
+
+         Defines an upper bound for the frequency at which this router wants to receive
+         :term:`BFD` control messages.
+         The effective interval at which the remote router will send control messages is the
+         result of negotiating with the remote router during session establishment;
+         the value will be ``max(remote.desired_min_tx_interval, required_min_rx_interval)``
+
+         Can be overridden for specific inter-AS BFD sessions with
+         :option:`bfd.required_min_rx_interval <topology-json required_min_rx_interval>`.
+
+.. _router-conf-topo:
+
+topology.json
+-------------
+
+The :program:`router` reads the ``border_routers`` section of the :ref:`topology.json <common-conf-topo>` file.
+
+It uses the entry referring to its own :option:`general.id <router-conf-toml general.id>`
+to determine the intra-AS links that this router instance is responsible for.
+The other router entries ("sibling routers") define which router is responsible for which
+interface. This mapping is consulted during packet forwarding to determine the
+sibling router to which a packet transitting the AS needs to forwarded to.
+
+Additionally, the :program:`router` considers the ``control_service`` and ``discovery_service``
+entries. These entries define the underlay addresses that the router uses to resolves
+anycast or multicast service addresses.
+
+.. _router-conf-keys:
+
+Keys
+----
+
+The :program:`router` loads the forwarding secret keys ``master0.key``/``master1.key`` from :option:`<config_dir>/keys <router-conf-toml general.config_dir>`.
+
+The key files contain a base64-encoded high-entropy random string.
+The keys should be exactly 16 bytes long (corresponding to a base64 encoding of 24 bytes with two trailing pad bytes ``==``).
+These keys must be identical to the :ref:`corresponding keys used by the control service <control-conf-keys>`.
+
+.. note::
+   The :program:`router` and :doc:`control` currently use these keys as input for PBKDF2 to generate
+   the actual forwarding key. Consequently, keys of any size can currently be used. This may be changed
+   to only accept high-entropy 16 byte keys directly in the future.

+SCION Overview
+**************
+
+Scope and Goals
+===============
+
+SCION is an inter-domain routing protocol, designed to provide route control, failure isolation, and
+explicit trust information for end-to-end communication.
+
+SCION's main goal is to offer highly available and efficient inter-domain packet delivery, even in
+the presence of actively malicious entities.
+
+SCION's aspiration is to improve *inter*-AS routing and to focuses on providing end-to-end
+connectivity. However, SCION does not solve *intra*-AS routing issues, nor does it provide
+end-to-end payload encryption, and identity authentication. These topics, which are equally
+important for the Internet to perform well, lie outside the scope of SCION.
+
+Concepts
+========
+
+.. _overview-isds:
+
+Isolation Domains (ISDs)
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+SCION organizes existing :term:`ASes <AS>` into groups of independent routing planes, called
+**Isolation Domains (ISD)**.
+An AS can be a member of multiple ISDs.
+All ASes in an ISD agree on a set of trust roots, called the **Trust Root Configuration (TRC)**.
+The ISD is governed by a set of **core ASes**, which provide connectivity to other ISDs and manage
+the trust roots.
+Typically, a few distinguished ASes within an ISD form the ISD’s core.
+Isolation domains serve the following purposes:
+
+- They allow SCION to support trust heterogeneity, as each ISD can independently define its roots of
+  trust;
+- They provide transparency for trust relationships;
+- They isolate the routing process within an ISD from external influences such as attacks and
+  misconfigurations; and
+- They improve the scalability of the routing protocol by separating it into a process within and
+  one between ISDs.
+
+ISDs provide natural isolation of routing failures and misconfigurations, provide meaningful and
+enforceable trust, enable :term:`endpoints <endpoint>` to optionally restrict traffic forwarding to
+trusted parts of the Internet infrastructure only, and enable scalable routing updates with high
+path-freshness.
+
+ISD and AS Numbering
+^^^^^^^^^^^^^^^^^^^^
+
+SCION decouples :term:`endpoint` addressing from inter-domain routing.
+Routing is based on the ISD-AS tuple, agnostic of endpoint addressing.
+
+ISD numbers are 16-bit identifiers.
+The 48-bit AS numbers are globally unique, and use a superset of the existing BGP AS numbering
+scheme.
+Formatting rules and allocations are currently described in `wiki page "ISD and AS numbering" <https://github.com/scionproto/scion/wiki/ISD-and-AS-numbering>`_.
+
+The endpoint local address is not used for inter-domain routing or forwarding, does not need to be
+globally unique, and can thus be an IPv4, IPv6, or MAC address, for example.
+A SCION endpoint address is the ``ISD-AS,local address`` 3-tuple.
+
+.. _overview-as-roles:
+
+AS Roles
+^^^^^^^^
+
+Some ASes have special roles in their ISD.
+The TRC of an ISD declares which AS has which designated roles.
+An AS can have multiple, or all, of these roles at the same time.
+
+- **Core ASes** have a special role in routing.
+  They are at the top of their ISD's routing domain, and connect their customer ASes to the outside.
+  Core ASes participate in the inter-ISD *and* the intra-ISD path-exploration process (see
+  `Routing`_ below).
+
+- **Certification authorities (CAs)** are responsible for issuing AS certificates to other ASes
+  and/or themselves.
+
+- **Voting ASes** and **Authoritative ASes** are related to the update mechanism for TRCs.
+  Voting ASes can "vote" to accept an updated TRC.
+  Authoritative ASes always have the latest TRCs of the ISD and start the announcement of a TRC update.
+
+.. _overview-link-types:
+
+Link Types
+^^^^^^^^^^
+
+There are three types of links between ASes in SCION:
+
+- A **core link** can only exist between two core ASes.
+- A **parent-child link** requires that both ASes are in the same ISD and
+  that at least one of the two connected ASes is a non-core AS.
+  ASes with a parent-child link usually belong to the same entity or have a provider-customer
+  relationship.
+  Every non-core AS needs at least one parent link.
+- A **peering link** also includes at least one non-core AS. The ASes may be in different ISDs.
+  Peering links are only available for use by children (direct or indirect) of the two linked ASes.
+
+Routing
+^^^^^^^
+
+SCION operates on two routing levels: intra-ISD and inter-ISD. Both levels use **path-segment
+construction beacons (PCBs)** to explore network paths. A PCB is initiated by a core AS and then
+disseminated either within an ISD (to explore intra-ISD paths) or among core ASes (to explore core
+paths across different ISDs). The PCBs accumulate cryptographically protected path and forwarding
+information on the AS-level, and store this information in the form of **hop fields (HFs)**.
+Endpoints use information from these hop fields to create end-to-end forwarding paths for data
+packets, which carry this information in their packet headers.
+This concept is called **packet-carried forwarding state**. The concept also supports multi-path
+communication among :term:`endpoints <endpoint>`.
+
+The process of creating an end-to-end forwarding path consists of the following steps:
+
+1. First, an AS discovers paths to other ASes, during the *path exploration* (or beaconing) phase.
+2. The AS then selects a few PCBs according to defined policies, transforms the selected PCBs into
+   path segments, and registers these segments with its path infrastructure, thus making them
+   available to other ASes. This happens during the *path registration* phase.
+3. During the *path resolution* phase, the actual creation of an end-to-end forwarding path to the
+   destination takes place. For this, an endpoint performs (a) a *path lookup* step, to obtain path
+   segments, and (b) a *path combination* step, to combine the forwarding path from the segments.

+Absolute time and DRKey selection
+=================================
+
+This section proposes an implementation method to find out the Security Association from the
+SPAO metadata information, i.e., to select the DRKey to authenticate the packet.
+
+Firstly, the receiver entity defines an *acceptance window*.
+An *acceptance window* (aw) is a time range of width *a* around the receiver's current time *T*,
+i.e.,:
+
+:math:`aw := [T-a/2, T+a/2)`
+
+
+[i] The acceptance window is equal or smaller than the minimum DRKey epoch length.
+
+The receiver entity derives the absolute timestamp and selects the associated DRKey by:
+
+1. Given a time instant *T*, considering:
+
+   - Epoch :math:`E_{i}` as the one whose time range includes *T*.
+   - Epoch :math:`E_{i-1}` as the prior epoch to :math:`E_{i}`.
+   - Epoch :math:`E_{i+1}` as the subsequent epoch to :math:`E_{i}`.
+
+2. Adding the relative timestamp (*RelTime*) (the one in :ref:`SPAO Header<authenticator-option>`) to
+   the start time for :math:`E_{i-1}`, :math:`E_{i}` and :math:`E_{i+1}`,
+   computing the respective *absolute times* (*AbsTime*):
+   :math:`at_{i-1}`, :math:`at_{i}` and :math:`at_{i+1}`.
+3. Given [i] at most one *absolute time* will be within *aw*.
+4. The candidate DRKey is the key whose epoch is associated to *AbsTime*,
+   e.g., if *AbsTime* is :math:`at_{i-1}` the key belonging to :math:`E_{i-1}`.
+
+Note that :math:`at_{i-1}` might, for instance be within the :ref:`Grace period<drkey-grace>`, i.e.,
+overlapping at :math:`E_{i}`. Nevertheless, due to [i] we can unambiguously distinguish it.

-Authentication
---------------
-SCMP messages can be authenticated with a MAC based on a symmetric key

-The MAC is transported in the :ref:`authenticator-option` End-to-End extension
-header.
-
-The Authenticator MAC algorithm is AES-CMAC (identifier :code:`0`).
-
-SCMP error messages MUST always be authenticated.
-SCMP informational messages CAN optionally be authenticated; a response message
-MUST be authenticated if and only if the corresponding request message was
-authenticated.
-
-All DRKey keys used here are derived with :ref:`protocol identifier <drkey-protocol-identifiers>` :code:`SCMP`, decimal :code:`1`.
-
-SCMP messages from (and to) routers are authenticated with :ref:`AS-host keys <drkey-as-host>`.
-SCMP response messages from a router in AS :math:`D` to a node :math:`H_s` in
-AS :math:`S` are authenticated with the DRKey :math:`K_{D,S:H_s}`.
-SCMP requests (specifically, :ref:`traceroute-request`) processed by a router
-are authenticated with the same key.

-SCMP messages between two end-hosts are authenticated with :ref:`host-host keys <drkey-host-host>`.
-An SCMP response message from a node :math:`H_d` in AS :math:`D` to a node
-:math:`H_s` in AS :math:`S` is authenticated with the key
-:math:`K_{D:H_d,S:H_s}`.
-SCMP requests and data packets from :math:`H_s` to :math:`H_d` are
-authenticated with this same key.
-
-For packets addressed to a router directly (specifically for
-:ref:`echo-request` and :ref:`echo-reply`) it is treated like an end-host and
-the corresponding host-host keys are used.

-   Recall that :ref:`traceroute-request`\s are *not* addressed to the router.

 Processing Rules

    #. A packet whose source address does not uniquely identify a single node.

-#. Every SCMP error message MUST be authenticated.
-
-   Every SCMP informational reply message MUST be authenticated if and only if
-   the corresponding request was authenticated.
-
-   .. note::
-      Consequentially, an implementation without support for SCMP
-      authentication MUST never send SCMP error messages and MUST NOT reply to
-      authenticated SCMP informational request messages.
-
-#. When an SCMP message is received, the receiver SHOULD check the
-   authentication header.
-
-   - SCMP error messages without or with an invalid authentication header and
-     SCMP informational messages with an invalid authentication header SHOULD
-     be silently dropped.
-
-     .. note::
-        As SCMP authentication is a new addition, there will be a transition period
-        during which receivers may accept SCMP error messages without authentication.
-
-   - The receiver checks that the :ref:`DRKey identified by the SPI <spao-spi-drkey>`
-     is appropriate for the SCMP message type and code, as described above in
-     the :ref:`section Authentication <scmp-authentication>`.
-
-   - The receiver derives or fetches the relevant key for validation of the MAC.
-
-   - Before checking the authentication, and in particular before fetching a
-     key, the receiver SHOULD check whether the quoted message was possibly
-     recently sent via/to the originator of the error message.
-
-   - The receiver MUST limit the traffic to the control service to fetch keys
-     for verifying the authentication of an SCMP message.
-     At most one packet SHOULD be sent to fetch the key for a received SCMP
-     message. If this fails or is not possible (e.g. because there is no
-     existing TCP session to the control service), the message SHOULD be
-     silently dropped.

+Tutorial: Freestanding SCION Network
+====================================
+
+This document helps you set up a freestanding SCION demo network, which consists of a stand-alone complete SCION environment distributed among five computers. The demo environment contains one SCION Isolation Domain (:term:`ISD`), with three core Autonomous Systems (:term:`AS`) and two non-core, leaf ASes.
+
+- If you want to go deep and help develop SCION, use the development environment. See :ref:`setting-up-the-development-environment`.
+- If you want to experiment with SCION in a larger environment, use SCIONLab. For more information, see https://www.scionlab.org/.
+
+**Note**: This tutorial does **not** describe how to set up SCION endhosts. For endhosts please follow the instructions of your `SCION library or application <https://github.com/scionproto/awesome-scion>`_.
+
+Setup
+-----
+
+This first section provides an overview of the setup and topology of the sample demo environment.
+
+Infrastructure
+..............
+
+The sample SCION demo setup consists of one ISD with three core ASes and two non-core, leaf ASes. The following table lists some details of the sample ISD and each AS in it, such as the DNS names, the ISD- and AS numbers, the kind of AS (core or leaf) and the IP addresses. This infrastructure could be virtual machines or bare metal.

+Sample SCION Demo Topology
+..........................
+
+The topology of the ISD includes the inter-AS connections to neighboring ASes, and defines the underlay IP/UDP addresses of services and routers running in this AS. This is specified in topology files - this guide later explains how to configure these files. A following graphic depicts the topology on a high level.

+
+
+
+.. _prerequisites:
+
+Infrastructure Prerequisites
+----------------------------
+
+This deployment requires five virtual machines (VMs) - one for each AS. We recommend using Ubuntu VMs for this.
+
+- 5 VMs - **Ubuntu** 22.04.3 LTS (Jammy Jellyfish). For more information, see `Ubuntu Jammy Jellyfish <https://releases.ubuntu.com/jammy/>`_.
+- Each VM should have at least one IP address reachable by the other VMs. (If on AWS, be sure to set up the appropriate security groups.)
+- Each VM will need internet access to download the required files (or you will need an alternate way to download the SCION binaries).
+- One VM (scion01) should have SSH access (password or SSH keys) to the other hosts scion{02-05} to copy generated configuration files and keys.
+- Using the naming convention for each VM of scion01, scion02, scion03, scion04, and scion05 will help follow along with this tutorial.
+- The VM names scion01-scion05 can be configured in /etc/hosts.
+
+
+Tasks to Perform
+----------------
+
+To create the sample ISD environment, you need to perform the following tasks, in this order:
+
+- Task 1: OS setup (:ref:`step0`)
+- Task 2: Installation (:ref:`step1`)
+- Task 3: Configuration (:ref:`step2`)
+- Task 4: Testing your environment (:ref:`step3`)
+
+The following sections explain the required tasks, one section per task.
+
+
+.. _step0:
+
+OS Setup
+........
+
+- Set up the host file
+
+  The host file (*/etc/hosts*) will need to be updated with the IP addresses of 5 VMs. This will need to be updated on scion01-scion05. Replace the IP addresses with the assigned IP addresses for the VMs deployed.
+
+  Set this up on scion01-scion05.
+
+  .. code-block:: sh
+
+     # additions to /etc/hosts
+     10.0.0.1 scion01
+     10.0.0.2 scion02
+     10.0.0.3 scion03
+     10.0.0.4 scion04
+     10.0.0.5 scion05
+
+
+.. _step1:
+
+Software Download and Installation
+..................................
+
+
+The SCION software can be installed from :ref:`Debian packages <install-debian-packages>`, downloaded from our `latest release <https://github.com/scionproto/scion/releases/>`_.
+Note that we have to install the software five times, on each of the VMs scion01-scion05.
+Execute the following commands on each VM:
+
+.. code-block:: sh
+
+   cd /tmp/
+   wget https://github.com/scionproto/scion/releases/download/v0.11.0/scion_v0.11.0_deb_amd64.tar.gz
+   tar xfz scion_v0.11.0_deb_amd64.tar.gz
+
+   sudo apt install ./scion*.deb
+
+
+As each virtual machine represents an AS in your demo environment, we will now refer to the VMs as ASes.
+
+
+.. _step2:
+
+Configuration
+.............
+
+To configure your demo SCION environment, perform the following steps.
+
+Step 1 - AS Topology Files
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For this tutorial, we have provided the AS :ref:`topology files <common-conf-topo>` - one per each AS. These files represent each AS's local view of the global network topology described above.
+
+- **AS 1 (42-ffaa:1:1)**: :download:`topology1.json <deploy/topology1.json>`
+- **AS 2 (42-ffaa:1:2)**: :download:`topology2.json <deploy/topology2.json>`
+- **AS 3 (42-ffaa:1:3)**: :download:`topology3.json <deploy/topology3.json>`
+- **AS 4 (42-ffaa:1:4)**: :download:`topology4.json <deploy/topology4.json>`
+- **AS 5 (42-ffaa:1:5)**: :download:`topology5.json <deploy/topology5.json>`
+
+Download the AS topology files onto each host scion01 through scion05.
+
+Copy the download link above and use ``wget`` to download appropriate file for each host, installing it as ``/etc/scion/topology.json``.
+On scion01, download the topology1.json file. On scion02, download topology2.json and repeat as such on scion03, scion04, and scion05.
+
+.. code-block:: sh
+
+   wget LINK_TO_TOPOLOGY.JSON_FILE -O /etc/scion/topology.json
+
+The AS topology files reference the hosts scion01-05 by host name.
+Ensure that you have set up the ``/etc/hosts`` file (:ref:`see above <step0>`) or replace the hostnames with IP addresses.
+
+Step 2 - Generate the Required Certificates
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The various cryptographic certificates need to be generated for each of the ASes.
+This requires first setting up the :term:`TRC` for this ISD, and then issuing AS-certificates from the :term:`CAs <CA>`.
+
+For the sake of simplicity in this tutorial, we create all the keys and certificates centrally, and distribute the crypto material to the individual ASes.
+In practice, the private keys of ASes are of course never revealed to other entities; the TRC would be created in a :ref:`trc-ceremony` involving representatives of all core ASes. The creation of the AS-certificates would involve a certificate-signing request to the CA.
+
+.. admonition:: Challenge
+
+   Instead of following the steps below, act out the full TRC creation ceremony and the creation of AS certificates via certificate signing requests.
+   Refer to the documentation on the :ref:`trc-ceremony`, :ref:`ca-cert` and :ref:`ca-ops-as-certs`.
+
+
+
+#. To generate all required certificates, execute the following script on any machine where ``scion-pki`` is installed (e.g. scion01).
+
+   .. code-block:: bash
+
+      #!/bin/bash
+
+      set -euo pipefail
+
+      mkdir /tmp/tutorial-scion-certs && cd /tmp/tutorial-scion-certs
+      mkdir AS{1..5}
+
+      # Create voting and root keys and (self-signed) certificates for core ASes
+      pushd AS1
+      scion-pki certificate create --profile=sensitive-voting <(echo '{"isd_as": "42-ffaa:1:1", "common_name": "42-ffaa:1:1 sensitive voting cert"}') sensitive-voting.pem sensitive-voting.key
+      scion-pki certificate create --profile=regular-voting <(echo '{"isd_as": "42-ffaa:1:1", "common_name": "42-ffaa:1:1 regular voting cert"}') regular-voting.pem regular-voting.key
+      scion-pki certificate create --profile=cp-root <(echo '{"isd_as": "42-ffaa:1:1", "common_name": "42-ffaa:1:1 cp root cert"}') cp-root.pem cp-root.key
+      popd
+
+      pushd AS2

+
+
+   .. note::
+
+      The script above will generate a new TRC for your ISD and must be done exactly once. Once you deploy such TRC on your machines, further TRC updates must be sequential. If for any reason you need to reset your setup and you need to deploy a fresh new TRC generated with the script above, then you must first delete the local DB files on your hosts (in ``/var/lib/scion/``).
+
+
+#. The just-generated crypto material in can now be copied to the respective AS VMs.
+
+  .. code-block:: bash
+
+     cd /tmp/tutorial-scion-certs
+     for i in {1..5}
+     do
+        ssh scion0$i 'mkdir -p /etc/scion/{crypto/as,certs}'
+        scp AS$i/cp-as.{key,pem} scion0$i:/etc/scion/crypto/as/
+        scp ISD42-B1-S1.trc scion0$i:/etc/scion/certs/
+     done
+
+
+Step 3 - Generate Forwarding Secret Keys
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Two symmetric keys *master0.key* and *master1.key* are required per AS as the forwarding :ref:`secret keys <router-conf-keys>`. These symmetric keys are used by the AS in the data plane to verify the MACs in the hop fields of a SCION path (header).
+
+.. code-block:: bash
+
+   head -c 16 /dev/urandom | base64 - > /etc/scion/keys/master0.key
+   head -c 16 /dev/urandom | base64 - > /etc/scion/keys/master1.key
+
+Repeat the above on each host scion01 - scion05.
+
+
+Step 4 - Service Configuration Files
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Next, you have to download the service configuration file for the router and control service into the ``/etc/scion/`` directory of each AS host scion01-scion05.
+Refer to the :ref:`router-conf-toml` and :ref:`control-conf-toml` manuals for details.
+We use default settings for most of the available options, so that the same configuration file can be used in all of the VMs.
+
+Download the files, then copy it into the ``/etc/scion/`` directory of each host scion01 - scion05.
+
+- **Border router**: :download:`br.toml <deploy/br.toml>`
+- **Control service**: :download:`cs.toml <deploy/cs.toml>`
+
+Step 5 - Start the Services
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Start the SCION services on each of the five ASes.
+Specifically, we start the :doc:`/manuals/router`, :doc:`/manuals/control`, :doc:`/manuals/daemon`
+and :doc:`/manuals/dispatcher` processes, by starting their systemd units. The dispatcher starts
+automatically as dependency of the control service and daemon.
+
+Execute the following commands on every AS:
+
+.. code-block:: sh
+
+   sudo systemctl start scion-router@br.service
+   sudo systemctl start scion-control@cs.service
+   sudo systemctl start scion-daemon.service
+   # Check that all services are active
+   systemctl status scion-*.service
+
+These steps need to be repeated on each host scion01 - scion05.
+
+
+.. _step3:
+
+Testing the Environment
+.......................
+
+You can now test your environment. The code block below includes some tests you could perform to check whether your environment works well.
+
+- Verify that each host has a SCION address. This can be verified with the :ref:`scion address <scion_address>` command as shown below.
+
+   .. code-block:: none
+
+      scion01$ scion address
+      42-ffaa:1:1,127.0.0.1
+
+- Verify that each host can ping the other hosts via SCION. This can be done with the :ref:`scion ping <scion_ping>` command. In the example below, we are pinging between scion01 (AS 42-ffaa:1:1) to scion05 (AS 42-ffaa:1:5). Very that each AS can ping every other AS.
+
+   .. code-block:: none
+
+      scion01$ scion ping 42-ffaa:1:5,127.0.0.1 -c 5
+      Resolved local address:
+      127.0.0.1
+      Using path:
+      Hops: [42-ffaa:1:1 3>1 42-ffaa:1:3 4>2 42-ffaa:1:5] MTU: 1472 NextHop: 127.0.0.1:31002
+
+      PING 42-ffaa:1:5,127.0.0.1:0 pld=0B scion_pkt=112B
+      120 bytes from 42-ffaa:1:5,127.0.0.1: scmp_seq=0 time=0.788ms
+      120 bytes from 42-ffaa:1:5,127.0.0.1: scmp_seq=1 time=3.502ms

+      120 bytes from 42-ffaa:1:5,127.0.0.1: scmp_seq=3 time=3.838ms
+      120 bytes from 42-ffaa:1:5,127.0.0.1: scmp_seq=4 time=3.401ms
+
+      --- 42-ffaa:1:5,127.0.0.1 statistics ---

+      rtt min/avg/max/mdev = 0.788/2.968/3.838/1.105 ms
+
+- Verify that each host has a full table of available paths to the other ASes. This can be done with the :ref:`scion showpaths <scion_showpaths>` command. In the example below, we are displaying the paths between scion01 (AS 42-ffaa:1:1) to scion05 (AS 42-ffaa:1:5). There should be multiple paths through the core ASes.
+
+   .. code-block:: none
+
+      scion01$ scion showpaths 42-ffaa:1:5
+      Available paths to 42-ffaa:1:5
+      3 Hops:
+      [0] Hops: [42-ffaa:1:1 2>1 42-ffaa:1:2 3>1 42-ffaa:1:5] MTU: 1472 NextHop: 127.0.0.1:31002 Status: alive LocalIP: 127.0.0.1

+
+Conclusion
+----------
+
+Congratulations, you now have a working SCION configuration, which consists of a stand-alone complete SCION environment distributed among five computers. This environment contains one SCION Isolation Domain (ISD), with three core ASes and two non-core, leaf ASes. Being a demo, this configuration has some limitations:
+
+- The certificates are only good for three days unless explicitly renewed using :ref:`scion-pki certificate renew <scion-pki_certificate_renew>`.
+- Each AS contains a single host running all the SCION services. In a typical deployment, these services would run a separate hosts and include multiple border routers.
+- This environment does not include a :doc:`SCION-IP gateway </manuals/gateway>`.

+        Licensable by such Contributor to use, reproduce, make available,

+
+     b. under Patent Claims of such Contributor to make, use, sell, offer for
+        sale, have made, import, and otherwise transfer either its
+        Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+     The licenses granted in Section 2.1 with respect to any Contribution
+     become effective for each Contribution on the date the Contributor first
+     distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+     The licenses granted in this Section 2 are the only rights granted under
+     this License. No additional rights or licenses will be implied from the
+     distribution or licensing of Covered Software under this License.
+     Notwithstanding Section 2.1(b) above, no patent license is granted by a
+     Contributor:
+
+     a. for any code that a Contributor has removed from Covered Software; or
+
+     b. for infringements caused by: (i) Your and any other third party's
+        modifications of Covered Software, or (ii) the combination of its
+        Contributions with other software (except as part of its Contributor
+        Version); or
+
+     c. under Patent Claims infringed by Covered Software in the absence of
+        its Contributions.
+
+     This License does not grant any rights in the trademarks, service marks,
+     or logos of any Contributor (except as may be necessary to comply with
+     the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+     No Contributor makes additional grants as a result of Your choice to
+     distribute the Covered Software under a subsequent version of this
+     License (see Section 10.2) or under the terms of a Secondary License (if
+     permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+     Each Contributor represents that the Contributor believes its
+     Contributions are its original creation(s) or it has sufficient rights to
+     grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+     This License is not intended to limit any rights You have under
+     applicable copyright doctrines of fair use, fair dealing, or other
+     equivalents.
+
+2.7. Conditions
+
+     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+     Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+     All distribution of Covered Software in Source Code Form, including any
+     Modifications that You create or to which You contribute, must be under
+     the terms of this License. You must inform recipients that the Source
+     Code Form of the Covered Software is governed by the terms of this
+     License, and how they can obtain a copy of this License. You may not
+     attempt to alter or restrict the recipients' rights in the Source Code
+     Form.
+
+3.2. Distribution of Executable Form
+
+     If You distribute Covered Software in Executable Form then:
+
+     a. such Covered Software must also be made available in Source Code Form,
+        as described in Section 3.1, and You must inform recipients of the
+        Executable Form how they can obtain a copy of such Source Code Form by
+        reasonable means in a timely manner, at a charge no more than the cost
+        of distribution to the recipient; and
+
+     b. You may distribute such Executable Form under the terms of this
+        License, or sublicense it under different terms, provided that the
+        license for the Executable Form does not attempt to limit or alter the
+        recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+     You may create and distribute a Larger Work under terms of Your choice,
+     provided that You also comply with the requirements of this License for
+     the Covered Software. If the Larger Work is a combination of Covered
+     Software with a work governed by one or more Secondary Licenses, and the
+     Covered Software is not Incompatible With Secondary Licenses, this
+     License permits You to additionally distribute such Covered Software
+     under the terms of such Secondary License(s), so that the recipient of
+     the Larger Work may, at their option, further distribute the Covered
+     Software under the terms of either this License or such Secondary
+     License(s).
+
+3.4. Notices
+
+     You may not remove or alter the substance of any license notices
+     (including copyright notices, patent notices, disclaimers of warranty, or
+     limitations of liability) contained within the Source Code Form of the
+     Covered Software, except that You may alter any license notices to the
+     extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+     You may choose to offer, and to charge a fee for, warranty, support,
+     indemnity or liability obligations to one or more recipients of Covered
+     Software. However, You may do so only on Your own behalf, and not on
+     behalf of any Contributor. You must make it absolutely clear that any
+     such warranty, support, indemnity, or liability obligation is offered by
+     You alone, and You hereby agree to indemnify every Contributor for any
+     liability incurred by such Contributor as a result of warranty, support,
+     indemnity or liability terms You offer. You may include additional
+     disclaimers of warranty and limitations of liability specific to any
+     jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+   If it is impossible for You to comply with any of the terms of this License
+   with respect to some or all of the Covered Software due to statute,
+   judicial order, or regulation then You must: (a) comply with the terms of
+   this License to the maximum extent possible; and (b) describe the
+   limitations and the code they affect. Such description must be placed in a
+   text file included with all distributions of the Covered Software under
+   this License. Except to the extent prohibited by statute or regulation,
+   such description must be sufficiently detailed for a recipient of ordinary
+   skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+     fail to comply with any of its terms. However, if You become compliant,
+     then the rights granted under this License from a particular Contributor
+     are reinstated (a) provisionally, unless and until such Contributor
+     explicitly and finally terminates Your grants, and (b) on an ongoing
+     basis, if such Contributor fails to notify You of the non-compliance by
+     some reasonable means prior to 60 days after You have come back into
+     compliance. Moreover, Your grants from a particular Contributor are
+     reinstated on an ongoing basis if such Contributor notifies You of the
+     non-compliance by some reasonable means, this is the first time You have
+     received notice of non-compliance with this License from such
+     Contributor, and You become compliant prior to 30 days after Your receipt
+     of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+     infringement claim (excluding declaratory judgment actions,
+     counter-claims, and cross-claims) alleging that a Contributor Version
+     directly or indirectly infringes any patent, then the rights granted to
+     You by any and all Contributors for the Covered Software under Section
+     2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+     license agreements (excluding distributors and resellers) which have been
+     validly granted by You or Your distributors under this License prior to
+     termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+   Covered Software is provided under this License on an "as is" basis,
+   without warranty of any kind, either expressed, implied, or statutory,
+   including, without limitation, warranties that the Covered Software is free
+   of defects, merchantable, fit for a particular purpose or non-infringing.
+   The entire risk as to the quality and performance of the Covered Software
+   is with You. Should any Covered Software prove defective in any respect,
+   You (not any Contributor) assume the cost of any necessary servicing,
+   repair, or correction. This disclaimer of warranty constitutes an essential
+   part of this License. No use of  any Covered Software is authorized under
+   this License except under this disclaimer.
+
+7. Limitation of Liability
+
+   Under no circumstances and under no legal theory, whether tort (including
+   negligence), contract, or otherwise, shall any Contributor, or anyone who
+   distributes Covered Software as permitted above, be liable to You for any
+   direct, indirect, special, incidental, or consequential damages of any
+   character including, without limitation, damages for lost profits, loss of
+   goodwill, work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses, even if such party shall have been
+   informed of the possibility of such damages. This limitation of liability
+   shall not apply to liability for death or personal injury resulting from
+   such party's negligence to the extent applicable law prohibits such
+   limitation. Some jurisdictions do not allow the exclusion or limitation of
+   incidental or consequential damages, so this exclusion and limitation may
+   not apply to You.
+
+8. Litigation
+
+   Any litigation relating to this License may be brought only in the courts
+   of a jurisdiction where the defendant maintains its principal place of
+   business and such litigation shall be governed by laws of that
+   jurisdiction, without reference to its conflict-of-law provisions. Nothing
+   in this Section shall prevent a party's ability to bring cross-claims or
+   counter-claims.
+
+9. Miscellaneous
+
+   This License represents the complete agreement concerning the subject
+   matter hereof. If any provision of this License is held to be
+   unenforceable, such provision shall be reformed only to the extent
+   necessary to make it enforceable. Any law or regulation which provides that
+   the language of a contract shall be construed against the drafter shall not
+   be used to construe this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+      Mozilla Foundation is the license steward. Except as provided in Section
+      10.3, no one other than the license steward has the right to modify or
+      publish new versions of this License. Each version will be given a
+      distinguishing version number.
+
+10.2. Effect of New Versions
+
+      You may distribute the Covered Software under the terms of the version
+      of the License under which You originally received the Covered Software,
+      or under the terms of any subsequent version published by the license
+      steward.
+
+10.3. Modified Versions
+
+      If you create software not governed by this License, and you want to
+      create a new license for such software, you may create and use a
+      modified version of this License if you rename the license and remove
+      any references to the name of the license steward (except to note that
+      such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+      Licenses If You choose to distribute Source Code Form that is
+      Incompatible With Secondary Licenses under the terms of this version of
+      the License, the notice described in Exhibit B of this License must be
+      attached.
+
+Exhibit A - Source Code Form License Notice
+
+      This Source Code Form is subject to the
+      terms of the Mozilla Public License, v.
+      2.0. If a copy of the MPL was not
+      distributed with this file, You can
+      obtain one at
+      http://mozilla.org/MPL/2.0/.
+
+If it is not possible or desirable to put the notice in a particular file,
+then You may include the notice in a location (such as a LICENSE file in a
+relevant directory) where a recipient would be likely to look for such a
+notice.
+
+You may add additional accurate notices of copyright ownership.
+
+Exhibit B - "Incompatible With Secondary Licenses" Notice
+
+      This Source Code Form is "Incompatible
+      With Secondary Licenses", as defined by

-   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
-
-   1. Definitions.

-
-      "You" (or "Your") shall mean an individual or Legal Entity
-      exercising permissions granted by this License.
-
-      "Source" form shall mean the preferred form for making modifications,
-      including but not limited to software source code, documentation
-      source, and configuration files.
-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,
-      and issue tracking systems that are managed by, or on behalf of, the
-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.
-
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"
-      replaced with your own identifying information. (Don't include
-      the brackets!)  The text should be enclosed in the appropriate
-      comment syntax for the file format. We also recommend that a
-      file or class name and description of purpose be included on the
-      same "printed page" as the copyright notice for easier
-      identification within third-party archives.

+SQLite Is Public Domain
+
+All of the code and documentation in SQLite has been dedicated to the public
+domain by the authors. All code authors, and representatives of the companies
+they work for, have signed affidavits dedicating their contributions to the
+public domain and originals of those signed affidavits are stored in a firesafe
+at the main offices of Hwaci. Anyone is free to copy, modify, publish, use,
+compile, sell, or distribute the original SQLite code, either in source code
+form or as a compiled binary, for any purpose, commercial or non-commercial,
+and by any means.
+
+The previous paragraph applies to the deliverable code and documentation in
+SQLite - those parts of the SQLite library that you actually bundle and ship
+with a larger application. Some scripts used as part of the build process (for
+example the "configure" scripts generated by autoconf) might fall under other
+open-source licenses. Nothing from these build scripts ever reaches the final
+deliverable SQLite library, however, and so the licenses associated with those
+scripts should not be a factor in assessing your rights to copy and use the
+SQLite library.
+
+All of the deliverable code in SQLite has been written from scratch. No code
+has been taken from other projects or from the open internet. Every line of
+code can be traced back to its original author, and all of those authors have
+public domain dedications on file. So the SQLite code base is clean and is
+uncontaminated with licensed code from other projects.

-A. HISTORY OF THE SOFTWARE
-==========================
-
-Python was created in the early 1990s by Guido van Rossum at Stichting
-Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
-as a successor of a language called ABC.  Guido remains Python's
-principal author, although it includes many contributions from others.
-
-In 1995, Guido continued his work on Python at the Corporation for
-National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
-in Reston, Virginia where he released several versions of the
-software.
-
-In May 2000, Guido and the Python core development team moved to
-BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
-year, the PythonLabs team moved to Digital Creations, which became
-Zope Corporation.  In 2001, the Python Software Foundation (PSF, see
-https://www.python.org/psf/) was formed, a non-profit organization
-created specifically to own Python-related Intellectual Property.
-Zope Corporation was a sponsoring member of the PSF.
-
-All Python releases are Open Source (see http://www.opensource.org for
-the Open Source Definition).  Historically, most, but not all, Python
-releases have also been GPL-compatible; the table below summarizes
-the various releases.
-
-    Release         Derived     Year        Owner       GPL-
-                    from                                compatible? (1)
-
-    0.9.0 thru 1.2              1991-1995   CWI         yes
-    1.3 thru 1.5.2  1.2         1995-1999   CNRI        yes

-    2.1.2           2.1.1       2002        PSF         yes
-    2.1.3           2.1.2       2002        PSF         yes
-    2.2 and above   2.1.1       2001-now    PSF         yes
-
-Footnotes:
-
-(1) GPL-compatible doesn't mean that we're distributing Python under
-    the GPL.  All Python licenses, unlike the GPL, let you distribute
-    a modified version without making your changes open source.  The
-    GPL-compatible licenses make it possible to combine Python with
-    other software that is released under the GPL; the others don't.
-
-(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
-    because its license has a choice of law clause.  According to
-    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
-    is "not incompatible" with the GPL.
-
-Thanks to the many outside volunteers who have worked under Guido's
-direction to make these releases possible.

+# quic-go patches
+
+The [ignore.patch](./ignore.patch) ignores the qtls-go1-20 dependency that is
+generated by gazelle. qtls-go1-20 requires Go version 1.20, and is hidden behind
+a build tag that gazelle ignores. Bazel then tries to build qtls-go1-20 with Go 1.19,
+which obviously does not work.
+
+This patch can be removed as soon as we update the Go version.

+Patch is copied from https://github.com/abitofhelp/connect-go-example/blob/main/import.patch
+
+It is required because of the issue described in https://github.com/bazelbuild/rules_go/issues/3951.
+The connect protoc plugin generates files in a sub-directory, which is not supported by the rules_go.
+This patch allows to override the import path of the generated files.
+
+There is also an upstream discussion whether there should be support for generating files in
+the directory itself rather than in a sub-directory. See:

+// Package processmetrics provides a custom collector to export process-level metrics beyond what
+// prometheus.ProcesssCollector offers.  This implementation is restricted to Linux. The generic
+// implementation does nothing.
+//
+// The metrics we add serve to estimate the available cpu time; that is, the amount of CPU that the
+// scheduler granted to the process, independently of whether it ran with it or slept on it. The
+// goal is to measure what the overall performance of the process would be if it was never
+// preempted. For example, this could be expressed as some_output/available_cpu_time.
+//
+// At a given time, a given thread is either running, runnable, or sleeping. When running it
+// consumes exactly one core. When runnable, it is being deprived of exactly one core (because Go
+// does not create more runnable threads than there are cores, there is no other thread of that
+// process that is receiving it.). So, for our accounting purposes, the total time that all the
+// process's threads spend "runnable" is the total core*time that the process did not receive. The
+// complement of that: the available_cpu_time is: num_cores * real_time - total_runnable_time.
+//
+// We expose only running and runnable times. Available time can be inferred more conveniently in
+// prometheus queries depending on the desired unit. For example:
+// * available_cpu_seconds_per_seconds = num_cores - rate(process_runnable_seconds_total)
+// * available_machine_seconds_per_seconds = 1 - rate(process_runnable_seconds_total)/num_cores
+//
+// Example of a query for processed_pkts per available cpu seconds:
+//
+//	rate(router_processed_pkts_total[1m])
+//	  / on (instance, job) group_left ()
+//	(num_cores - rate(process_runnable_seconds_total[1m]))
+//
+// Example of a query that only looks at on-cpu efficiency;
+//
+//	rate(router_processed_pkts_total[1m])
+//	  / on (instance, job) group_left ()
+//	(rate(process_running_seconds_total[1m]))
+//
+// The effective number of cores is best obtained from the go runtime. However, no prometheus
+// collector seems to expose it yet, so we surface it here for convenience and simplicity
+// under the name go_maxprocs_threads.

-// Package reliable implements the SCION ReliableSocket protocol
-//
-// Servers should first call Listen on a UNIX socket address, and then call
-// Accept on the received Listener.
-//
-// Clients should either call:
-//
-//	Dial, if they do not want to register a receiving address with the remote end
-//	  (e.g., when connecting to SCIOND);
-//	Register, to register the address argument with the remote end
-//	  (e.g., when connecting to a dispatcher).
-//
-// ReliableSocket common header message format:
-//
-//	8-bytes: COOKIE (0xde00ad01be02ef03)
-//	1-byte: ADDR TYPE (NONE=0, IPv4=1, IPv6=2, SVC=3)
-//	4-byte: data length
-//	var-byte: Destination address (0 bytes for SCIOND API)
-//	  +2-byte: If destination address not NONE, destination port
-//	var-byte: Payload
-//
-// ReliableSocket registration message format:
-//
-//	13-bytes: [Common header with address type NONE]
-//	 1-byte: Command (bit mask with 0x04=Bind address, 0x02=SCMP enable, 0x01 always set)
-//	 1-byte: L4 Proto (IANA number)
-//	 8-bytes: ISD-AS
-//	 2-bytes: L4 port
-//	 1-byte: Address type
-//	 var-byte: Address
-//	+2-bytes: L4 bind port  \
-//	+1-byte: Address type    ) (optional bind address)
-//	+var-byte: Bind Address /
-//	+2-bytes: SVC (optional SVC type)
-//
-// To communicate with SCIOND, clients must first connect to SCIOND's UNIX socket. Messages
-// for SCIOND must set the ADDR TYPE field in the common header to NONE. The payload contains
-// the query for SCIOND (e.g., a request for paths to a SCION destination). The reply header
-// contains the same fields, and the reply payload contains the query answer.
-//
-// To receive messages from remote SCION hosts, hosts can register their address and
-// port with the SCION dispatcher. The common header of a registration message uses an address
-// of type NONE. The payload contains the address type of the registered address, the address
-// itself and the layer 4 port.
-//
-// To send messages to remote SCION hosts, hosts fill in the common header
-// with the address type, the address and the layer 4 port of the remote host.
-//
-// Reads and writes to the connection are thread safe.

+# COREMARK® ACCEPTABLE USE AGREEMENT 
+
+This ACCEPTABLE USE AGREEMENT (this “Agreement”) is offered by Embedded Microprocessor Benchmark Consortium, a California nonprofit corporation (“Licensor”), to users of its CoreMark® software (“Licensee”) exclusively on the following terms.
+
+Licensor offers benchmarking software (“Software”) pursuant to an open source license, but carefully controls use of its benchmarks and their associated goodwill. Licensor has registered its trademark in one of the benchmarks available through the Software, COREMARK, Ser. No. 85/487,290; Reg. No. 4,179,307 (the “Trademark”), and promotes the use of a standard metric as a benchmark for assessing the performance of embedded systems. Solely on the terms described herein, Licensee may use and display the Trademark in connection with the generation of data regarding measurement and analysis of computer and embedded system benchmarking via the Software (the “Licensed Use”).
+
+## Article 1 – License Grant.
+1.1.	License. Subject to the terms and conditions of this Agreement, Licensor hereby grants to Licensee, and Licensee hereby accepts from Licensor, a personal, non-exclusive, royalty-free, revocable right and license to use and display the Trademark during the term of this Agreement (the “Term”), solely and exclusively in connection with the Licensed Use. During the Term, Licensee (i) shall not modify or otherwise create derivative works of the Trademark, and (ii) may use the Trademark only to the extent permitted under this License. Neither Licensee nor any affiliate or agent thereof shall otherwise use the Trademark without the prior express written consent of Licensor, which may be withheld in its sole and absolute discretion. All rights not expressly granted to Licensee hereunder shall remain the exclusive property of Licensor.
+
+1.2.	Modifications to the Software.  Licensee shall not use the Trademark in connection with any use of a modified, derivative, or otherwise altered copy of the Software.
+
+1.3.	Licensor’s Use. Nothing in this Agreement shall preclude Licensor or any of its successors or assigns from using or permitting other entities to use the Trademark, whether or not such entity directly or indirectly competes or conflicts with Licensee’s Licensed Use in any manner. 
+
+1.4.	Term and Termination.  This Agreement is perpetual unless terminated by either of the parties.  Licensee may terminate this Agreement for convenience, without cause or liability, for any reason or for no reason whatsoever, upon ten (10) business days written notice. Licensor may terminate this Agreement effective immediately upon notice of breach.  Upon termination, Licensee shall immediately remove all implementations of the Trademark from the Licensed Use, and delete all digitals files and records of all materials related to the Trademark. 
+
+## Article 2 – Ownership.
+2.1.	Ownership. Licensee acknowledges and agrees that Licensor is the owner of all right, title, and interest in and to the Trademark, and all such right, title, and interest shall remain with Licensor. Licensee shall not contest, dispute, challenge, oppose, or seek to cancel Licensor’s right, title, and interest in and to the Trademark. Licensee shall not prosecute any application for registration of the Trademark. Licensee shall display appropriate notices regarding ownership of the Trademark in connection with the Licensed Use.
+
+2.2.	Goodwill. Licensee acknowledges that Licensee shall not acquire any right, title, or interest in the Trademark by virtue of this Agreement other than the license granted hereunder, and disclaims any such right, title, interest, or ownership. All goodwill and reputation generated by Licensee’s use of the Trademark shall inure to the exclusive benefit of Licensor. Licensee shall not by any act or omission use the Trademark in any manner that disparages or reflects adversely on Licensor or its Licensed Use or reputation. Licensee shall not take any action that would interfere with or prejudice Licensor’s ownership or registration of the Trademark, the validity of the Trademark or the validity of the license granted by this Agreement. If Licensor determines and notifies Licensee that any act taken in connection with the Licensed Use (i) is inaccurate, unlawful or offensive to good taste; (ii) fails to provide for proper trademark notices, or (iii) otherwise violates Licensee’s obligations under this Agreement, the license granted under this Agreement shall terminate. 
+
+## Article 3 – Indemnification. 
+3.1.	Indemnification Generally.  Licensee agrees to indemnify, defend, and hold harmless (collectively “indemnify” or “indemnification”) Licensor, including Licensor’s members, managers, officers, and employees (collectively “Related Persons”), from and against, and pay or reimburse Licensor and such Related Persons for, any and all third-party actions, claims, demands, proceedings, investigations, inquiries (collectively, “Claims”), and any and all liabilities, obligations, fines, deficiencies, costs, expenses, royalties, losses, and damages (including reasonable outside counsel fees and expenses) associated with such Claims, to the extent that such Claim arises out of (i) Licensee’s material breach of this Agreement, or (ii) any allegation(s) that Licensee’s actions infringe or violate any third-party intellectual property right, including without limitation, any U.S. copyright, patent, or trademark, or are otherwise found to be tortious or criminal (whether or not such indemnified person is a named party in a legal proceeding).  
+
+3.2.	Notice and Defense of Claims. Licensor shall promptly notify Licensee of any Claim for which indemnification is sought, following actual knowledge of such Claim, provided however that the failure to give such notice shall not relieve Licensee of its obligations hereunder except to the extent that Licensee is materially prejudiced by such failure. In the event that any third-party Claim is brought, Licensee shall have the right and option to undertake and control the defense of such action with counsel of its choice, provided however that (i) Licensor at its own expense may participate and appear on an equal footing with Licensee in the defense of any such Claim, (ii) Licensor may undertake and control such defense in the event of the material failure of Licensee to undertake and control the same; and (iii) the defense of any Claim relating to the intellectual property rights of Licensor or its licensors and any related counterclaims shall be solely controlled by Licensor with counsel of its choice. Licensee shall not consent to judgment or concede or settle or compromise any Claim without the prior written approval of Licensor (whose approval shall not be unreasonably withheld), unless such concession or settlement or compromise includes a full and unconditional release of Licensor and any applicable Related Persons from all liabilities in respect of such Claim.
+
+## Article 4 – Miscellaneous.
+4.1.	Relationship of the Parties. This Agreement does not create a partnership, franchise, joint venture, agency, fiduciary, or employment relationship between the parties. 
+
+4.2.	No Third-Party Beneficiaries. Except for the rights of Related Persons under Article 3 (Indemnification), there are no third-party beneficiaries to this Agreement.
+
+4.3.	Assignment. Licensee’s rights hereunder are non-assignable, and may not be sublicensed. 
+
+4.4.	Equitable Relief. Licensee acknowledges that the remedies available at law for any breach of this Agreement will, by their nature, be inadequate.  Accordingly, Licensor may obtain injunctive relief or other equitable relief to restrain a breach or threatened breach of this Agreement or to specifically enforce this Agreement, without proving that any monetary damages have been sustained, and without the requirement of posting of a bond prior to obtaining such equitable relief.
+
+4.5.	Governing Law. This Agreement will be interpreted, construed, and enforced in all respects in accordance with the laws of the State of California, without reference to its conflict of law principles. 
+
+4.6.	Attorneys’ Fees.  If any legal action, arbitration or other proceeding is brought for the enforcement of this Agreement, or because of an alleged dispute, breach, default, or misrepresentation in connection with any of the provisions of this Agreement, the successful or prevailing party shall be entitled to recover its reasonable attorneys’ fees and other reasonable costs incurred in that action or proceeding, in addition to any other relief to which it may be entitled.
+
+4.7.	Amendment; Waiver.  This Agreement may not be amended, nor may any rights under it be waived, except in writing by Licensor.
+
+4.8.	Severability. If any provision of this Agreement is held by a court of competent jurisdiction to be contrary to law, the provision shall be modified by the court and interpreted so as best to accomplish the objectives of the original provision to the fullest extent 
+permitted by law, and the remaining provisions of this Agreement shall remain in effect.
+
+4.9.	Entire Agreement. This Agreement constitutes the entire agreement between the parties and supersedes all prior and contemporaneous agreements, proposals or representations, written or oral, concerning its subject matter.

+Topic: Description
+        Benchmark using a linked list.
+
+        Linked list is a common data structure used in many applications.
+
+        For our purposes, this will excercise the memory units of the processor.
+        In particular, usage of the list pointers to find and alter data.
+
+        We are not using Malloc since some platforms do not support this
+library.
+
+        Instead, the memory block being passed in is used to create a list,
+        and the benchmark takes care not to add more items then can be
+        accommodated by the memory block. The porting layer will make sure
+        that we have a valid memory block.
+
+        All operations are done in place, without using any extra memory.
+
+        The list itself contains list pointers and pointers to data items.
+        Data items contain the following:
+
+        idx - An index that captures the initial order of the list.
+        data - Variable data initialized based on the input parameters. The 16b
+are divided as follows: o Upper 8b are backup of original data. o Bit 7
+indicates if the lower 7 bits are to be used as is or calculated. o Bits 0-2
+indicate type of operation to perform to get a 7b value. o Bits 3-6 provide
+input for the operation.

+

+Topic: Description
+        Matrix manipulation benchmark
+
+        This very simple algorithm forms the basis of many more complex
+algorithms.
+
+        The tight inner loop is the focus of many optimizations (compiler as
+well as hardware based) and is thus relevant for embedded processing.
+
+        The total available data space will be divided to 3 parts:
+        NxN Matrix A - initialized with small values (upper 3/4 of the bits all
+zero). NxN Matrix B - initialized with medium values (upper half of the bits all
+zero). NxN Matrix C - used for the result.
+
+        The actual values for A and B must be derived based on input that is not
+available at compile time.

+Topic: Description
+        Simple state machines like this one are used in many embedded products.
+
+        For more complex state machines, sometimes a state transition table
+implementation is used instead, trading speed of direct coding for ease of
+maintenance.
+
+        Since the main goal of using a state machine in CoreMark is to excercise
+the switch/if behaviour, we are using a small moore machine.
+
+        In particular, this machine tests type of string input,
+        trying to determine whether the input is a number or something else.
+        (see core_state.png).

+   Command line arguments. This is the preferred method if command line

+   is available on the platform, a system function which is not a stub can be
+   used.

+        e.g. read the value on GPIO pins connected to switches, or invoke
