Hi,

Thanks,

It would be greatly helpful if that information is included in the document
shepherd writeup when the doc is submitted to the IESG.

Hello David,

You're perfectly right. We did the exercise last year, before accepting
both I-D as WG Items.

1- Concerning LDPC-Staircase codes, you'll find opinions at:

http://www.ietf.org/mail-archive/web/fecframe/current/msg00816.html
http://www.ietf.org/mail-archive/web/fecframe/current/msg00811.html
http://www.ietf.org/mail-archive/web/fecframe/current/msg00810.html

In the meantime LDPC-Staircase codes have been adopted as the
primary AL-FEC scheme for the Japanese ISDB-Tmm standard.
Both open-source and commercial codecs are available. And if you do
want the check by yourself their performance, you can:
http://openfec.org

2- Concerning Reed-Solomon codes, they are so commonly used
that I don't think we need any official support.

Cheers,

   Vincent
