  • 2. P2P Researchers Just Support Piracy? ? P2P = Illegal File Sharing 1999 2000 2001 2002 2003 2004 ≠ illegal file sharing 2005 2006 2007 2008 … KOM – Multimedia Communications Lab 2
  • 3. What is Peer-to-Peer?Client/Server Relationship Peer-to-Peer Relationship 1. 2. 3. For Supervisor from Kalman Kalman Supervisor Kalman Supervisorin Hannover in Darmstadt in Hannover in Darmstadt Challenge! 2. 1. Find where ‘Supervisor’ is Find yourself where and take care that the ‘Supervisor’ is and take care message arrives that the message arrives KOM – Multimedia Communications Lab 3
  • 4. Internet Communication: 1960s and Now Started as a peer-to-peer system…  The early Internet (late 1960s, ARPANET)  Goal: share computing resources SRI UCLA Utah First ARPANET imp log: The first message ever to be sent over the UCSB ARPANET from the UCLA SDS Sigma 7 Host computer to the SRI SDS 940 Host computer. The switch to master/slave or client/server  The explosion of Internet on 1994 brought millions of people on network  People needs just to send e-mail, surf the Web, buy the things  they just request the service and wait for the answer  People are just temporary connected to Internet (via dial-up, DSL)  Shortage of IP addresses (user-to-host name ratio ≈ 5) KOM – Multimedia Communications Lab 4
  • 5. Example of Client-Server Communication KOM – Multimedia Communications Lab 5
  • 6. Client-Server Communication: Drawbacks + + bottleneck - + - scalable? € -+ - costs - - - single-point-of- failure + + + KOM – Multimedia Communications Lab 6
  • 7. Peer-to-Peer Communication - + + - - - Share resources  Share costs + +  Avoid bottlenecks + + - - - + KOM – Multimedia Communications Lab 7
  • 8. Research & Development ofNew (Peer-to-Peer) Applications? Problem StatementRESEARCH What to research? Review of the State of the Art What is already done? Specification SolutionDEVELOPMENT What to make? Inventing! Design Evaluation How to make it? Does the idea work? Implementation Make it! Testing Does it work? Hard, risky, slow!
