Changelog

All notable changes to the sdntrace_cp NApp will be documented in this file.

[UNRELEASED] - Under development

[2024.1.0] - 2024-07-23

Changed

  • Updated python environment installation from 3.9 to 3.11
  • Upgraded UI framework to Vue3

[2023.2.0] - 2024-02-16

Added

  • Support "instructions" to perform a match.
  • Support instruction type goto_table.
  • Added UI to sdntrace_cp.

[2023.1.0] - 2023-06-12

Added

  • Support "untagged" and "any" on EVCs.
  • PUT /trace and /traces endpoints validate payload with @validate_openapi.

Changed

  • Update tracepath to support the trace type: loop. Other three types are starting for the first trace_step, intermediary for subsequent trace_steps (previously trace), and last for a terminating last switch where a flow lookup matched.
  • Add new case of loop when the outgoing interface is the same as the input interface.
  • Remove last_id and traces parameters
  • Remove GET /api/amlight/sdntrace_cp/trace/{trace_id} in openapi.yml
  • v1 prefix was added on the API routes to stabilize this NApp.

Fixed

  • Check the actions field in flows when running a trace to avoid KeyError.
  • In PUT /trace and PUT /traces, field switch` is defined as required, as well as its parameters dpid` and in_port.
  • Check that an interface has been found with find_endpoint given switch and port at each trace_step.

Removed

  • Removed TRIGGER_SCHEDULE_TRACES, TRIGGER_IMPORTANT_CIRCUITS and FIND_CIRCUITS_IN_FLOWS from settings.
  • Removed automate in main.
  • Removed update_circuits functionality in main.
  • Removed the dependency on apscheduler.

General Information

  • @rest endpoints are now run by starlette/uvicorn instead of flask/werkzeug.

[2022.3.1] - 2023-02-27

Changed

  • PUT /traces will return the results in order, without aggregating them by dpid. Also, failed traces are not omitted.

[2022.3.0] - 2022-12-15

Added

  • Added apscheduler library to handle job scheduling
  • Added PUT /traces endpoint for bulk requests
  • Added output port information to the trace result (last step) to help validating intra-switch EVCs

Changed

  • The functionality match_and_aply has been added to match flows and apply actions. This matches a given packet against the stored flows.

Removed

  • Removed dependency from amlight/scheduler
  • Removed support for OpenFlow 1.0
  • Unsubscribe to the amlight/flow_stats.flows_updated event
  • Dependency on flow_stats has been removed, from where the functionality match_and_aply was previously used.

[2022.2.1] - 2022-08-15

Fixed

  • Made a shallow copy when iterating on shared data structure to avoid RuntimeError size changed

[2022.2.0] - 2022-08-08

Fixed

  • [Issue 25] Fix tracepath results to display correct vlan id when using Q-in-Q

General Information

  • Increased unit test coverage to at least 85%

[2022.1.0] - 2022-02-08

Added

  • Added FIND_CIRCUITS_IN_FLOWS settings option to enable or disable the feature to trigger the find_circuits routine
  • Enhanced and standardized setup.py install_requires to install pinned dependencies
  • [Issue 5] Add setup.py and requirements

Fixed

  • [Issue 6] Fix comparison of endpoints when an endpoint does not provide all necessary fields
  • [Issue 8] Change log level of run_traces results to debug
