This document describes a Fully-Specified Forward Error Correction
(FEC) scheme, corresponding to FEC Encoding ID 1, for the Raptor
forward error correction code and its application to reliable
delivery of data objects.

Raptor is a fountain code, i.e., as many encoding symbols as needed
can be generated by the encoder on-the-fly from the source symbols of
a source block of data.  The decoder is able to recover the source
block from any set of encoding symbols only slightly more in number
than the number of source symbols.

The Raptor code described here is a systematic code, meaning that all
the source symbols are among the encoding symbols that can be
generated.  [STANDARDS TRACK]
