This is a minor update only, primarily to update the version of the TCP throughput equation used, and to clarify a few points raised at the last meeting. A more significant update can be expected later in the summer.

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.
