This document generally describes how to use Forward Error Correction
(FEC) codes to efficiently provide and/or augment reliability for data
transport.  The primary focus of this document is the application of
FEC codes to one-to-many reliable data transport using IP
multicast.  This document describes what information is needed to
identify a specific FEC code, what information needs to be
communicated out-of-band to use the FEC code, and what information is
needed in data packets to identify the encoding symbols they carry.
The procedures for specifying FEC codes and registering them with the
Internet Assigned Numbers Authority (IANA) are also described.  This
document should be read in conjunction with and uses the terminology
of the companion document titled, "The Use of Forward Error Correction
(FEC) in Reliable Multicast".

This document is a product of the Reliable Multicast Transport Working
Group of the IETF.
