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 these applications, then network congestion can
lead to uncontrolled packet loss, and a resulting deterioration of
the user's multimedia experience. The congestion control algorithm
acts as a safety measure, stopping RTP flows from using excessive
resources, and protecting the network from overload. At the time of
this writing, however, while there are several proprietary solutions,
there is no standard algorithm for congestion control of interactive
RTP flows.
This document does not propose a congestion control algorithm. It
instead defines a minimal set of RTP circuit breakers: conditions
under which an RTP sender needs to stop transmitting media data, to
protect the network from excessive congestion. It is expected that,
in the absence of long-lived excessive congestion, RTP applications
running on best-effort IP networks will be able to operate without
triggering these circuit breakers. Future RTP congestion control
specifications will be expected to operate within the constraints
defined by these circuit breakers.
