i believe there are/were only four NAPs, so scheduling should not be a problem.
it seems that many folk do not know that NSF let contracts involving four NAPs, Pennsauken, AADS, PacBell, and MAE-East (i hope bit-rot has not set in so badly i blew that list). those are/were the only NAPs. there are many more excnagne points. the essence of what NSF said was that, to get a transition contract, a provider had to be at the NAPs so others would know where/how to reach them. what they did not say was that the providers had to peer openly and provision sufficient bandwidth; but that's another story. i am sure this is all written down somewhere, which is good as i suffer from increasing bit-rot. i think george santayana had something to say about all this. randy
