-# distributed-coordination
-BA Lars Klenner: Fully distributed service coordination. Code building on the RealVNF/coord-sim
+Copy of https://github.com/ldklenner/coordination-simulation-ba-adapted/tree/adapted
+
+# Simulation: Coordination of chained virtual network functions
+
+Simulate flow-level, inter-node network coordination including scaling and placement of services and routing flows between them. Note: this repository holds an altered version of the original simulator [coord-sim](https://github.com/RealVNF/coordination-simulation), adapted to my needs in order to accomplish my bachelor thesis.
+
+
+**Additional features**:
+
+* Forwarding capabilities. Prior to this, forwarding happened implicit. Now flows are explicit forwarded over link, taking into account individual link utilization
+* Individual flow forwarding rules. A node can make a forwarding decision on individual flows.
+* Individual flow processing rules. A node can explicit decide if it will process a flow.
+* Extended simulator state and action interface.
+* Algorithm callback interface. To allow a external algorithm to capture certain event, it can register callback functions invoked by the flowsimulator.
+	* init_flow callback
+	* pass_flow callback
+	* periodic measurement callbacks.
+* Adapted metrics.
+* Egress node routing.
+* Extended simulator configuration
+
+
+## Setup
+
+Requires Python 3.6. Install with [virtualenv](https://virtualenv.pypa.io/en/stable/) to not break original coord-sim installation. Make sure to install simulator with adapted source files, located on the default `adapted` branch:
+```bash
+git checkout adapted
+```
+
+Then follow original setup procedure:
+```bash
+pip install -r requirements.txt
+```
+
+
+## Notes
+
+Due to the use of deprecated networkx functions and their removal in the 2.4 version, released while developing, the networkx library is locked to version 2.3
