  2. Contents • Introduction • The Need Peer to Peer • Why JXTA • Walk Through JXTA • Conclusion • References

  3. Introduction • JXTA stands for “juxtapose” that means putting things aside of each other. Simply, Peer-to-Peer

  4. History • JXTA started as JXTA SEARCH in June 2000 when Gene Kan and Yaroslav Faybishenko of Infrasearch created a demo search engine which connected multiple Web servers together using a peer-to-peer (P2P) protocol. • Nearly a year later, the Infrasearch team is now part of Sun’s Project JXTA. The Sun’s Project can be found on the site http://www.jxta.org

  5. Peer-to-Peer (P2P) • The Internet has three valuable fundamental assets • Information which are documents, audios, videos …etc. • Network capabilities ,“Bandwidth”. • Computing resources, such as processing, storage The Utilization Ratio for these assets is low ! Because of low end-user contributions

  6. The Effect of the Traditional Client-Server Computing Model • world produces about 2x1018 bytes of information every year, but only publishes about 3x1012 bytes. Moreover, Google claims that it searches about only 3.8x1010 web pages

  7. Continue • Many new fiber have been installed, the new installed bandwidth gets little use since everyone goes to same pages such as Amazon for books or to eBay for auctions. What happen is, “ hot spots just get hotter while cold pipes remain cold”

  8. JXTA Objective • Interoperability (peer groups, variety of services supported) • Platform Independence (Programming Language, OS, Network technology • Ubiquity (all digital devices, even not invented yet devices)

  9. JXTA Core Building Blocks • Peers • peer groups • Advertisements • Messages • Pipes • Services

  11. JXTA Protocols • Endpoint Routing Protocol (ERP) • The Peer Resolver Protocol • The Rendezvous Protocol • The Peer Discovery protocol (PDP) • The Peer Information Protocol (RIP) • The Pipe Binding Protocol

  12. Rendezvous Peer View • Rendezvous super peers maintains its own rendezvous peer view which is an ordered list of other known rendezvous in the peer group by their peer ID’s. • Rendezvous periodically select a given random number of rendezvous from their local RVP, and send them a random list of their known rendezvous. • Rendezvous check their neighbor rendezvous (+1 or more, -1 or less). • Rendezvous update and clean non-responding rendezvous from their RPV. • Rendezvous might retrieve rendezvous info from a predetermined set of bootstrapping seeding rendezvous.

  13. Edge peer Rendezvous connection • Check its cache for Rdv advertisement. • If No response try to propagate request through possible connections • If No response Try seed Rendezvous • If No response Be a Rendezvous

  14. Conclusion • JXTA considered one of the biggest project in P2P. • A project that unite all works of Peer to Peer • JXTA Open Source License attracts a lot of developers and companies.
