RFC 6363 describes a framework for using Forward Error Correction
(FEC) codes to provide protection against packet loss. The framework
supports applying FEC to arbitrary packet flows over unreliable
transport and is primarily intended for real-time, or streaming,
media. However, FECFRAME as per RFC 6363 is restricted to block FEC
codes. This document updates RFC 6363 to support FEC codes based on a
sliding encoding window, in addition to block FEC codes, in a
backward-compatible way. During multicast/broadcast real-time content
delivery, the use of sliding window codes significantly improves
robustness in harsh environments, with less repair traffic and lower
FEC-related added latency.
This document is a product of the Transport Area Working Group Working Group of
the IETF.
This is now a Proposed Standard.
