This document describes a Fully-Specified 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

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
