RTP Extensions for Transport-wide Congestion Control
M. Flodman, Erik Sprang, Stefan Holmer · 2015
This document proposes an RTP header extension and an RTCP message for use in congestion control algorithms for RTP-based media flows. It adds transport-wide packet sequence numbers and corresponding feedback message so that congestion control can be performed on a transport level at the send-side, while keeping the receiver dumb.
