Abstract:
The Real-time Transport Protocol (RTP) is widely used in telephony,
video conferencing, and telepresence applications. Such applications
are often run on best-effort UDP/IP networks. If congestion control
is not implemented in the applications, then network congestion will
deteriorate the user's multimedia experience. This document does not
propose a congestion control algorithm; rather, it defines a minimal
set of "circuit-breakers". Circuit-breakers are conditions under
which an RTP flow is expected to stop transmiting 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. Any
future RTP congestion control specification is expected to operate
within the envelope defined by these circuit breakers.
