[Rmt] Comment on Reed-Solomon I-D


Hi Vincent and team,

I noted that you only explicitly describe a Reed Solomon type that is not strictly MDS for the various, perfectly valid performance reasons cited.

For NORM purposes, I think it would also be useful for the draft to include a description a strict MDS systematic Reed Solomon algorithm. (Strict MDS makes it easier or more possible for NORM to implement an optimal repair strategy).

My NORM implementation has an unencumbered RS code of this type and I would be happy to help document it as an additional fully-specified Reed Solomon FEC scheme to be included in your document if you think that is appropriate?

best regards,

Brian Adamson

Hello everybody,

An Internet-draft describing a fully specified Reed-Solomon FEC scheme
is now available:

http://www.ietf.org/internet-drafts/draft-lacan-rmt-fec-bb-rs-00.txt


Abstract

   This document describes a Fully-Specified FEC scheme for the Reed-
   Solomon forward error correction code and its application to reliable
   delivery of data objects on the packet erasure channel.

   The Reed-Solomon codes belong to the class of Maximum Distance
   Separable (MDS) codes, i.e, they enable a receiver to recover the k
   source symbols from any set of k received symbols.

   The implementation described here is compatible with the IPR-free
   implementation described in [5].
