    • 1. Snow Computing Tinyfool twitter:@tinyfool mail:tinyfool@gmail.com http://code.google.com/p/snow-computing/
    • 2. Snow Computing • I like HuYou( ) • Why the name? • one next step of Cloud Computing • computing model like snow • all P2P in this document is theoretical, is generalized
    • 3. The Internet is a P2P Network • Internet is a graph • No one has all paths • Every node only has a limit routing table • routing table is dynamic • routing table equal to distance calculation
    • 4. KAD • Every node has an ID • A distance calculation algorithm • All nodes form a graph • Every content has an ID, node near the contents keep this contens‘ source information
    • 5. Six Degrees & network • Where the question come from (IM-P2P) ? • Look people as node • Look peoples’ relation as the measuring method of distance • search patten • Chain reaction search • DHT search
    • 6. Chain reaction search
    • 7. Snow Computing Architecture • Base on XMPP, Gtalk/Jabber, early version base on Mac OS X • An enhanced IM client, and plugins • Enhanced access control system base on IM account • Chain reaction search and DHT search
    • 8. Applications of Snow Computing • SNS system base on IM client • MapReduce in P2P • Intelligent agent
    • 9. SNS System Base On IM Client • Strong point • All SNS base on IM client • Traditional web SNS cost lots of resources • Don’t need copy your relationship to SNS database • Decentration, everyone ‘s information store in his IM client, safe and strong • Base on IM client, more power and more interactive than web SNS • Shortcoming • Once IM off line, SNS account/information off line (some sort of cache can provide copys of these information)
    • 10. MapReduce in P2P • Strong point • Base on Internet, can handle lager computing • Score system base on IM • Shortcoming • Big latency, Map better than Reduce • guess sort 1PB beat Google sort 1TB beated
    • 11. Intelligent agent • P2P spider • Distributed search • Some cool document share system • data mining base on P2P
