Research And Implementation Of Streaming Media System Base On P2P

With the development of network,Internet become one part of our life gradually.More and more Telecom service providers around the world pay attention to the value-added service.Especially the service of IPTV which base on streaming has a brighter future. In the past,the service of IPTV adopt the standard structure of C/S (Client/Server) .The structure of C/S has a fatal limitation that likely to get overloaded and has a single point of effectiveness which affected by the limitative processing capability of server and the bandwidth.The structure of Peer-to-Peer changes the mode of server-centric and makes every Peer equivalent in the network. Every Peer offers service for other Peers at the same time enjoys the services provided by other Peers. So IPTV based on P2P solve the problem of traditional IPTV service, and greatly boosts the application and development of IPTV.This paper recommends the anciently structure and technic character of P2P and the knowledge of streaming firstly. Then focus on the system composition and the protocol of Bittorrent. Then improve the piece-picker arithmetic of Bittorrent according to the feature of streaming. Ultimately unify the merit of traditional Content Distribution Network and P2P, produces an IPTV system great at deployment and operation. For the sake of transplanting to the set-top box, the system base on ACE that support for Linux, Windows, Solaris systems.
