Explore resource management approaches for P2P networks such as port filtering, MAC address filtering, and byte limiting. Address the issue of "abuse of the commons" and the need for responsible use of shared mediums. Consider the advantages of both connection-oriented and connectionless network topologies. Discuss the potential for applying the Internet's end-to-end principle to connection networks. Examine application-based routing in peer-to-peer networks and the concept of user-controlled routing in telephony systems.

P2P is good news“will force us to look for new solutions architectures in resource manegment”
Past approaches to resource management include port filtering, mac address filtering, byte limiting • It is the old problem of “abuse of the commons” on any shared medium • With a shared medium network administrator has to make sure medium is used responsibly • With P2P data flows so large maybe we need to go back to connection oriented topologies
Connection networks are not all bad • Telco business model and ATM gave connection networks a bad name • In future we may need both connection and connectionless networks (both have their advantages) • Two approaches to hybrid network: • QoS over connectionless • Best efforts over connections
Internet was so successful not because it was connectionless but because of the Internet e2e principle that enabled innovation by putting control at the edge • Can we do the same thing with connection networks?? • Peer to peer like Freenet, Fastlane(kazaa) with self organizing routers is application based routing • Routers are “connected” while the traffic is “connectionless”
CA*net 4 is first attempt to put connections under control of user • Working on concepts such like RPON that will extend CA*net 4 concept to individual user • Ultimate objective- peer to peer “telephone calls” but where user controls routing of the telephone switch
