This repository contains the P4 based implementation of BIER(-FRR) including the distributed control plane.
- Install: Contains the installation script, which installs all required dependencies.
- Controller-Implementation: Contains the Python implementation of the global Controller.
- Local-Controller: Contains the Python implementation of the local controller.
- P4-Implementation: Contains the data plane implementation of BIER(-FRR) in P4.
- protos: Contains the protobuf defintion for the communication between local and global controller.
Inside the Install folder, run ./setup.sh. This will install all required dependencies. The installation process has been verified for Ubuntu 18.0.4.2 LTS.
To start a mininet topology, go inside the P4-Implementation folder and run make run TOP=XXX where XXX is the desired topology, e.g. BIER/simple. The corresponding local controllers are automatically started.
When the mininet topology has started, the global controller can be started. To that end, go inside the Controller-Implementation folder and run ./controller --config ../P4-Implementation/examples/XXX/config.json where XXX is the previously started topology. The configuration file contains the grpc ports of the p4 switches and the configuration for the global controller, e.g. if node protection should be used.
When the mininet topology has started, a xterm session for the hosts can be invoked. Inside the mininet cli type xterm h1 to start a xterm session for the host h1. Inside the xterm session, type ./host_cli/main.py to open the host cli. The host cli features several functions, e.g. the (un-)subscription of multicast groups or to send a packet to a given ip address.
A documentation for the data plane implementation can be found in the repository wiki.
