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。
The rapid development of the Internet has made the study of P2P and its related fields become a hot spot, but the structure of P2P networks is not perfect at present. In this paper, several P2P models are introduced, and based on the advantages of these models, a P2P model is proposed for the dynamic characteristics of P2P networks. P2P network applications are evolving, P2P is an important core idea of sub-transmission, which uses the sub-algorithm for the development of P2P software we have an important reference value in this paper we analyze its sub-transmission algorithm , And combined with the reference Coolstreaming and boiling point network television system strategy, in the P2P network for video, audio and other multimedia streaming data transmission methods and performance analysis.
