Info

Increasingly Peer-to-Peer z My computers each need addresses all of the time z others get content from me z others can not only put data on my machines, but in many cases I don’t even know (or care) what the data is {in fact, I’d just as soon not know} - data sharing Napster/Gnutella/ICQ/Morpheus, KazAa, … z don’t need a firewall - I want others to use my machines - since they also let me use their machines (does this lead to the Metcalf law for peers, value is proportional to the peers 2 ) z user systems are clients and servers z (more general) Resource sharing - for example CPU sharing (SETI@HOME -- ~25 Teraflops of computing) z Service Sharing - rather than raw cycle or disk blocks, the servers now make higher level services available - a user does not have to know where the service is - it simply is and hence is available
IPv6 z Important transition z facilitate peer-to-peer z reduce costs and efforts for configuration of user’s machines (plug and serve) z importance of ANYCAST addressing But it is not arriving fast enough!
