Our paper on
Circuit Breakers for Multimedia Congestion Control was presented at
the 20th International Packet Video workshop in San Jose, CA, USA, on
12 December 2013.
The abstract reads: “Real-time multimedia flows comprise a
large, and increasing, fraction of the traffic on the Internet. An
important subset of that traffic, primarily due to interactive
applications, runs over UDP/IP, and requires applications to implement
congestion control to ensure the stability of the network. The IETF is
developing congestion control algorithms for such uses as part of the
new WebRTC standards, but there is no standard algorithm that can be
used at this time. We do not propose a congestion control algorithm.
Rather, we propose a circuit breaker for RTP sessions that can detect
when an application is causing excessive network congestion, and shut
down the transmission. This can be used as an envelope within which
congestion control algorithms can operate, providing a safety net to
prevent congestion collapse. We present the RTP circuit breaker
algorithm, and provide an initial performance evaluation to show that
it performs as desired.”
