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). The "+" between ukma, rutgers, gatech and husc6 are all NNTP links that each of us has with the others. At least, ukma has links with the other three and rutgers and gatech are connected, I don't know husc6's links very well. "triad" is probably a bad word. We each have normal type nntp links with each other. >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? That's an interesting thought. There have been a number of backbone sites created soley because of the NSFnet. I know that before we got on NSFnet we were STRUGGLING to find money to pay phone bills and even resorted to making a link with an IBM mainframe over BITNET to even have one full feed. The same has happened all over the country. A thought I had today was whether or not the rapidly increasing traffic loads have anything to do with all this new connectivity that the net is finding. A year ago it took quite a bit of effort on my part (and I'm pretty well motivated as far as Usenet goes) to have that one full feed. A less motivated version of me wouldn't have been able to keep it going and thus this site wouldn't have been able to generate much traffic. Now we've got really reliable news here and there's lots of traffic coming in which is prompting the local users to generate lots of traffic. food for thought ... >I also wonder about linus ... we're a hop away from husc6, and I don't >see much traffic through linus. Yeah, isn't the net a wonderful thing? We set up these links and then can't predict the way messages will propogate. >Are these maps generated by hand? Yes they are. -- <---- David Herron -- The E-Mail guy<---- s.k.a.: David le casse\*' {rutgers,uunet}!ukma!david, david@UKMA.BITNET <---- <---- Goodbye RAH.
