Lines: 25 Isn't there a new backbone in Spain, fed by mcvax? I don't understand some of the map. Like, why are ulysses, ubc-cs and vucomp on there, all dead ends (and vucomp a restricted link at that)? I submit that a 'backbone' link is to carry the news fast between other backbone links, and I don't see these sites as doing that (except for their leaf nodes ... hell, everybody does that). By the same token, alberta would have to be looked at. I can't decide what the rutgers-ukma link is. Two paths? Does the '+' mean all the connected sites talk to each other? Although it looks like rutgers is the center of the Usenet universe, some links are triads (rutgers/gatech/mcnc, rutgers/cmcl2/husc6, rutgers/ukma/gatech). Since I assume this is all NNTP traffic, I wonder how much Internet traffic would be cut by dropping some of those links, or making them mostly unidirectional? I also wonder about linus ... we're a hop away from husc6, and I don't see much traffic through linus. Are these maps generated by hand? ..Bob -- Bob Page, U of Lowell CS Dept. page@swan.ulowell.edu ulowell!page
