What is Peer-to-Peer?Client/Server Relationship Peer-to-Peer Relationship 1.2.3.For Supervisor from Kalman KalmanSupervisor Kalman Supervisorin Hannover in Darmstadt in Hannoverin Darmstadt Challenge! 2. 1.Find where Supervisor is Find yourself whereand take care that the Supervisor is and take caremessage arrivesthat 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 resourcesSRI UCLA UtahFirst ARPANET imp log:The first message ever to be sent over the UCSB ARPANET from the UCLA SDS Sigma 7 Hostcomputer to the SRI SDS 940 Hostcomputer. 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.
