Those are really interesting numbers. When you say "destination AS", are you counting that as "next hop" or "last hop"? I think the 40% number for 701 is counting "all that is reached by 701", i.e. "next hop" as opposed to that which is just within 701 i.e. "last hop"
I mean last hop by that. The next hop numbers depend entirely on who else we are connected to and our routing policy (which, incidentally, is to not transit anything over uunet that we don't have to because they are _so_ slow these days).
I'd be interested, though probably not in this forum, to hear what others have measured using these two different techniques, as it helps us plan our networks better.
check out the cflowd data exporter thing (I can't remember the specifics of it, because we only ran it a short while do to a bug in the experimental IOS release)... it breaks down outbound traffic by destination AS and exports the data, so you can see who you should buy your next connection to, etc. Josh Beck - CONNECTnet Network Operations Center - jbeck@connectnet.com ----------------------------------------------------------------------- CONNECTnet INS, Inc.
