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。
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.
