What is RMCAT congestion control, and how will it affect WebRTC?
RMCAT is an IETF Working Group which came out of proposal by myself and Harald Alvestrand, and an associated Congestion Control IAB/IRTF workshop at IETF 84 in Vancouver in 2012. The report from the workshop is RFC 7295.
The RMCAT WG is working to develop new congestion control protocols for realtime RTP traffic to improve on state-of-the-art, to ensure that media streams don’t harm other users of the networks (both non-RTP and other RTP media streams), and to maximize quality. There are several proposed algorithms, and this work will feed back into mainline WebRTC implementations to improve network usage and media quality. (more…)
