Methods to Convey Forward Error Correction (FEC)
Framework Configuration Information
Abstract
The Forward Error Correction (FEC) Framework document (RFC 6363)
defines the FEC Framework Configuration Information necessary for the
FEC Framework operation. This document describes how to use
signaling protocols such as the Session Announcement Protocol (SAP),
the Session Initiation Protocol (SIP), the Real Time Streaming
Protocol (RTSP), etc. for determining and communicating the
configuration information between sender(s) and receiver(s).
This document doesn't define any new signaling protocol.

1. Introduction
The FEC Framework document [RFC6363] defines the FEC Framework
Configuration Information that governs the overall FEC Framework
operation common to any FEC scheme. This information must be
available at both the sender and receiver(s).
This document describes how various signaling protocols such as the
Session Announcement Protocol (SAP) [RFC2974], the Session Initiation
Protocol (SIP) [RFC3261], the Real Time Streaming Protocol (RTSP)
[RFC2326], etc. could be used by the FEC scheme (and/or the Content
Delivery Protocol (CDP)) to communicate the configuration information

RFC 6695 FEC Framework Config Signaling August 2012
between the sender and receiver(s). The configuration information
may be encoded in any compatible format, such as the Session
Description Protocol (SDP) [RFC4566], XML, etc., though this document
refers to SDP encoding usage quite extensively.
