RTP Retransmission Payload Format
RFC 4588, “RTP Retransmission Payload Format”, is a Proposed Standard document published in July 2006 by J. Rey, D. Leon, A. Miyazaki, V. Varsa, R. Hakenberg. The canonical text is published by the RFC Editor.
Abstract
RTP retransmission is an effective packet loss recovery technique for real-time applications with relaxed delay bounds. This document describes an RTP payload format for performing retransmissions. Retransmitted RTP packets are sent in a separate stream from the original RTP stream. It is assumed that feedback from receivers to senders is available. In particular, it is assumed that Real-time Transport Control Protocol (RTCP) feedback as defined in the extended RTP profile for RTCP-based feedback (denoted RTP/AVPF) is available in this memo. [STANDARDS-TRACK]
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.
