摘　　要：在P2P流媒体点播系统中,节点可能收到过多的数据请求造成自身过载,导致网络节点负载的不均衡,影响了系统的整体性能。为了平衡节点间的负载,通过建立节点的信息列表管理节点的动态负载信息,设计了一种基于请求迁移的负载均衡(LBRM)算法。实验结果表明,LBRM算法解决了网络节点负载不均衡,提高了播放质量。In P2 PVoD systems,the nodes may receive too many data request and result in overload,this phenomenon leads to the imbalance of network load of nodes and affects performance of the system.In order to balance the load between nodes,a management list of the nodes information is established to manage the dynamic load information of nodes.Based on the load information,a load balancing algorithm based on request migration（LBRM）is proposed.Experimental result indicates that LBRM can solve load imbalance of nodes in network and improve play back quality.
