Live Streaming System Based On P2p Architecture Design And Realization

P2P(Peer-to-Peer) technology becomes more and more attractive these years , and is used in all fields of Internet, especially in streaming media ,file sharing and file searching.P2P is a type of Internet network allowing a group of computer users with the same networking program to connect with each other to share files instead of having to go through a central server .Decentralization is the primary feature of P2P, with which P2P takes large numbers of separate normal nodes to balance the load of whole network, so can minimize the cost and improve the capability of calculating.In this thesis, the recent advances of P2P network are introduced. Firstly, the common P2P systems in Internet and their disadvantages are introduced. Secondly, the project is to design and carry out a streaming media system which is based on the principle of decentralization and centered topology searching method ,the same as Napster system. At last, the security problems in P2P systems are discussed and the future is pointed out.
