Tim, et al-

I'm butting in and responding to this just in case Enrique Cuevas doesn't
see it.  As many of you know, this type of "performance mask" is specified
for satellite systems operating above 1.544/2 Mbps by ITU-R S.1062 and
ITU-T G.826 (and maybe some new ones I'm not familiar with).  This is
handled in the ITU-R for satellites by Working Party 4B, of which Enrique
is the US Chairman.  Since that group has formally offered to work with
TCPSAT and IETF on this subject, this might be a very good time to take
them up on it.  It would be really nice, someday, to have performance masks
that were "harmonized" and could support SDH, ATM *and* TCP/IP.

If I'm already "behind the times" let me know;  I just thought it worth
mentioning!

Cheers,
Eric
