摘要 针对CDN网络中海量数据分发的要求,设计了一种基于CDN服务器P2P服务的高效数据分发机制,通过对分割后的海量数据分别执行P2P数据分发,克服了现有CDN服务器P2P服务不能根据Internet网络带宽和CDN服务器负载动态变化自适应地调整数据分发过程的缺点。仿真结果表明,提出的海量数据分发机制提高了网络带宽波动对数据分发的性能,能够较好地满足实际CDN网络中海量数据分发的需求。 In order to meet requirement of high volume data distribution in CDN environment,the paper proposes a new P2P based high efficient data distribution mechanism,it does P2P data distribution to split data,it has no shortcoming of current P2P distribution method in CDN server,which can't adaptively adjust data distribution process according to Internet bandwidth variation and CDN servers'load variation.The simulation results gives that,the high volume data distribution mechanism proposed by this paper improves data distribution performance in real network environment,and can meet high volume data distribution requirement.
