RTP Control Protocol Feedback for Congestion Control
RFC 8888, “RTP Control Protocol Feedback for Congestion Control”, is a Proposed Standard document published in January 2021 by Z. Sarker, C. Perkins, V. Singh, M. Ramalho. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
