RTP Circuit Breaker algorithm published as RFC 8083
7 March 2017

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.
