摘要:

本文提出了一种基于P2P技术的多媒体网络会议设计模型,该模型采用Chord协议组织节点和实现节点路由定位,将服务器的职能分布到P2P Overlay的各节点上,并根据节点的异构性将它们分为普通节点和超级节点,各节点根据自身能力各尽所能,使网络资源得到充分利用,可有效解决C/S模式下中央服务器带来的性能瓶颈问题。仿真实验表明该网络会议系统模型具有负载均衡、易于扩展和高效的资源定位等特点。

Abstract:

This paper proposed a conference model based on P2P technology,which adopted Chord protocol to distribute the server function to many nodes in the network. Meanwhile,the system divided nodes into two parts:super nodes and ordinary nodes according to their ability,so as to take advantage of their abilities and eliminate the problem of server bottleneck in C/S structure. Simulation proved the advantage of load balancing,tolerance of fault and high scalability.

Key words: Internet conference, Chord, peer-to-peer network, P2Psim
