Here's our initial attempt at a "circuit breakers" draft for RTCWeb. Comments welcome - this is very much a straw-man for discussion, rather than a final solution. Colin Begin forwarded message:

Title : RTP Congestion Control: Circuit Breakers for Unicast Sessions Author(s) : Colin Perkins Varun Singh Filename : draft-perkins-avtcore-rtp-circuit-breakers-00.txt Pages : 14 Date : 2012-03-05
The Real-time Transport Protocol (RTP) is widely used for telephony, video conferencing, and telepresence applications. These applications are often used over best-effort UDP/IP networks. If congestion control is not implemented then network congestion will deteriorate the user's multimedia experience. This document does not propose a congestion control algorithm. Instead, it specifies a minimal set of "circuit-breakers". Circuit-breakers are conditions under which an RTP flow should cease to transmit media to protect the network from excessive congestion. It is expected that all RTP applications running on best-effort networks will be able to run without triggering these circuit breakers in normal operation.
