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 acts as a safety
measure to prevent starvation of network resources denying other
flows from access to the Internet, such measures are essential for an
Internet that is heterogeneous and for traffic that is hard to
predict in advance. This document does not propose a congestion
control algorithm; instead, it defines a minimal set of RTP circuit-
breakers. Circuit-breakers are conditions under which an RTP sender
needs to stop transmitting media data in order to protect the network
from excessive congestion. It is expected that, in the absence of
severe congestion, all RTP applications running on best-effort IP
networks will be able to run without triggering these circuit
breakers. Any future RTP congestion control specification will be
expected to operate within the constraints defined by these circuit
breakers.
