Re: XAUI and 64b/66b
Ariel,
To a certain extent, you are right about the "mother-in-lawish" nature of
some of the comments on this reflector, just as there are is a lot of
"emotional" attachment to certain coding schemes. I just get incensed when
something that I think is past us, keeps showing up again and again under
different names. I would have thought that people would have had more
respect for the participants of this group than to keep doing that.
Thank you for the remider that scamble coding has been successfully used in
the past for Ethernet PHYs. It validates my assertion that different coding
schemes should reflect the requirements of the PHYs, not have a particular
coding scheme define limitations of all of the different potential PHYs.
Thank you,
Roy Bynum
