中文摘要：

针对云计算数据中心网络（DCN）环境下，P2P流媒体服务器集群部署引起的较高带宽占用问题，提出了一种基于云计算的P2P流媒体服务器集群部署方法。该方法将P2P流媒体服务器集群部署建模为一个二次分配问题，并基于蚁群算法，寻找每个虚拟流媒体服务器与每个部署点之间的映射关系，实现基于云计算的P2P流媒体服务器集群部署。通过仿真实验证明，基于云计算的P2P流媒体服务器集群部署算法可以有效地减少云计算平台DCN网络带宽占用。

英文摘要：

Concerning the high bandwidth occupation problem caused by deploying the P2P （Peer-to-Peer） streaming media server cluster on the Data Center Network （DCN） in cloud, a P2P streaming media server cluster deployment algorithm based on cloud computing was proposed. This algorithm modeled the P2P streaming media server cluster deployment as a quadratic assignment problem, and sought the mapping relationship between each virtual streaming media server and each deployment point to realize the P2P streaming media server cluster deployment based on cloud computing. The simulation experiment demonstrates that the P2P streaming media server cluster deployment algorithm based on cloud computing can effectively reduce the bandwidth usage of DCN in cloud.
