No. There's a difference: computers (routers) handle the O(N^2) routing problem, while people would have to handle the O(N^2) cooperative AS problem. > Yes, one ASN is required per cooperating pair.

However, no two of them have the same other provider. What is gained by us setting up relationships with a bunch of other providers and getting special ASes assigned? What if one of those customers gets a connection to a third upstream, or if they change their upstream? Right now, it doesn't affect us (we don't have to do anything), but in your setup, it would require us to get yet another AS. Only one of our multihoming customers has a connection to someone we already have a connection with, so there's no path between our network and the rest. -- Chris Adams <[email protected]> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
