RE: Can P2P applications learn to play fair on networks?

Putting middleboxes into an ISP is not the same thing as putting intelligence into the network.

If the work focuses on making a P2P protocol that knows about ASNums and leverages middleboxes sitting in an ISP's network, then you would have a framework that can be used for more than just congestion control. > Host's treat network's as black boxes because they don't > really have any other choice in the matter. A router is a host that learns about the network topology by means of routing protocols, and then adjusts its behavior accordingly. Why can't other hosts similarly learn about the topology and adjust their behavior? --Michael Dillon
