This repository implements the test cases for congestion control for interactive real-time media described in RFC8867 for the algorithm(s) implemented in Pion.
The current implementation uses vnet.Net from
pion/transport to simulate network
constraints. There are two test applications, one using a simple simulcast-like
setup and the other one using adaptive bitrate streaming with a synthetic
encoder.
To run the simulcast test, you must create three input video files as described
in the bandwidth-esimation-from-disk
example
and place them in the vnet directory.

RFC 8868 describes guidelines to evaluate congestion control algorithms for interactive real-time media. Currently, live statistics can be viewed during the test run via a web interface. In future, we might automate the evaluation.
To run the tests, run go test -v ./vnet/.
The library is used as a part of our WebRTC implementation. Please refer to that roadmap to track our major milestones.
Pion has an active community on the Slack.
