数据分配是P2P流媒体系统的关键技术之一。多种分配算法亟须进行统一的评价。文章搭建了一个研究平台来模拟P2P流媒体系统的数据分配和下栽，并设计了不同带宽类型的供应节点带宽生成算法，对各种主流的数据分配算法进行了仿真对比测试。实验结果表明，该平台能够为全面衡量算法及发现系统参数变化对系统性能的影响提供有力的工具。%Data allocation is one of the key problems in Peer-to-peer Media streaming system. Various allocation algorithms urgently needed a unified evaluation. This paper built a research platform to simulate data distribution and downloading, and also designed the generation algorithms for different types of supplying peers＇ bandwidth. Experimental results show that the platform provides a powerful environment that can measure algorithms comprehensively and find out the algorithm parameters＇ impact on the system performance.
