Forward Error Correction (FEC) Framework
Abstract
This document describes a framework for using Forward Error
Correction (FEC) codes with applications in public and private IP
networks 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. This framework can be used to define Content Delivery
Protocols that provide FEC for streaming media delivery or other
packet flows. Content Delivery Protocols defined using this
framework can support any FEC scheme (and associated FEC codes) that
is compliant with various requirements defined in this document.
Thus, Content Delivery Protocols can be defined that are not specific
to a particular FEC scheme, and FEC schemes can be defined that are
not specific to a particular Content Delivery Protocol.
