An effective RTP congestion control algorithm requires more fine-
grained feedback on packet loss, timing, and Explicit Congestion
Notification (ECN) marks than is provided by the standard RTP Control
Protocol (RTCP) Sender Report (SR) and Receiver Report (RR) packets.
This document describes an RTCP feedback message intended to enable
congestion control for interactive real-time traffic using RTP. The
feedback message is designed for use with a sender-based congestion
control algorithm, in which the receiver of an RTP flow sends back to
the sender RTCP feedback packets containing the information the
sender needs to perform congestion control.
