摘　　要：流媒体应用在近年来获得了飞速的发展,流媒体服务器在用户并发度和存储容量两个方面的需求日益增高,在这种背景下,集群式流媒体服务器逐渐成为高端流媒体服务器的主流.集群式流媒体服务器的研究工作非常需要科学的仿真工具来协助,一方面能够测试算法的性能和普适性,另一方面可以通过仿真分析对服务器的硬件资源进行优化配置.本文在介绍集群式流媒体服务器的体系结构和性能分析的基础上,设计并实现了一套分布式流媒体仿真工具和集群式流媒体服务器实验床.最后基于仿真实验的数据,得到一些提高集群式流媒体服务器性能和资源优化配置的有益结论.In recent years, with the rapid development of streaming media applications, the requirement of both user concurrency and storage capacity of streaming media server is growing ; in this context, cluster streaming media server gradually becomes the mainstream of high-end streaming media server. The research work about cluster streaming media server much requires simulation tool to test its performance and optimize the allocation of hardware resources. Based on the analysis of cluster streaming media server＇s architecture and performance, this paper designs and implements a distributed simulation tool and a cluster streaming media server test bed. At last, some useful conclusions, which can increase cluster performance and optimize the allocation of resources, have been draw based on the simulation data.
