RTP Circuit Breaker algorithm published as RFC 8083
Our work to define a circuit breaker algorithm for unicast RTP sessions has finally been published by the IETF as RFC 8083. This RFC defines a minimal set of RTP circuit breakers: conditions under which an RTP sender needs to stop transmitting media data, in order to protect the network from excessive congestion. It does not propose a congestion control algorithm, leaving that for other specifications, such as those under development in the IETF's RTP Media Congestion Avoidance Techniques working group.
The RTP circuit breaker is a realisation of the circuit breaker concept, designed for a particular transport protocol. The more general concept is described in a companion RFC, RFC 8084, that describes the need for circuit breakers in general, and defines requirements for designing a circuit breaker.
