A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : Raptor Forward Error Correction (FEC) Schemes for Objects
Author(s) : M. Luby, M. Shokrollahi
Filename : draft-luby-rmt-bb-fec-raptor-object-00.txt
Pages : 41
Date : 2004-10-21
This document describes the Raptor code and its application to reliable
delivery of objects. Two Fully-Specified Forward Error Correction (FEC)
schemes are introduced, one for a non-systematic version of Raptor and
one for a systematic version of Raptor, that supplements the FEC schemes
described in RFC 3452.
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. 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.

In the body type:
"FILE /internet-drafts/draft-luby-rmt-bb-fec-raptor-object-00.txt".
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
Internet-Draft.
