map-exchanging scheme), three huge churny databases (the mapping of information to URL, the mapping of hostname to IP address and the mapping of IP addresses to paths)
Just for the record, I *was* kidding. I don't actually think I have the time or expertise to make it work. However, I think the idea is worth looking at. Two of the "three huge churny databases" (info to URL, url to IP) already are in place, and I bet the overhead involved in an un-cached IP lookup is a lot more than that of an SPF walk through a BGP tree.
Some people already have a database of IP address to path that is used to more effectively route traffic from caching proxy hierarchies over multiple international connections. ******************************************************** Michael Dillon voice: +1-650-482-2840 Senior Systems Architect fax: +1-650-482-2844 PRIORI NETWORKS, INC. http://www.priori.net "The People You Know.
