分组P2P网络模型分包传输策略分析

Internet的飞速发展使对等网络（P2P）及其相关领域的研究成为热点,但是当前P2P网络的结构并不完善.文中介绍了几种P2P模型,并在综合这几种模型优点的基础上,针对P2P网络的动态特性提出了一种分组P2P模型.P2P的网络应用在正不断发展,P2P中的一个重要核心思想是分包传输,它所采用的分包算法对于我们开发P2p软件具有重要的参考价值.我们在本文中分析它的分包传输算法,并且结合参考Coolstreaming和沸点网络电视系统中的策略,对在P2P网络中进行视频、音频等多媒体流数据的传输的方法和性能进行分析.

A Study Of The P2P Architecture and Transfer Strategy

With the rapid development of Internet, study about peer to peer networks becomes hot , but the structure of P2P network is notperfect. P2P network application is growing, one of the core method of P2P is Segments Assignment and transfer stragety, Bittorrent is a very excellent P2P privacy protocol,In this paper we will analysis its algorithm,and reference the strategy of the CoolStreaming and Feidian P2P Network TV system,and analysis the method and performance of transfering the audio and video data stream in the P2P network.
