I have to chuckle reading this thread.
Attempts to "standardize" inter-NOC communication happened a couple of
times in the early 90's in the IETF, but it got too ugly, with too many
barriers (basically people not wanting to expose dirty laundry). I fear
that attempts to do so now when the providers are *really* competing with
each other (as opposed to back in the old daze when we were all
friends :-) will suffer the same fate, other than on a pairwise basis between
NOCs that cooperate well with each other anyway.
