摘　　要：提出了基于对等网络的流媒体接纳控制算法,针对不同节点有不同的入口带宽和出口带宽,优先选择贡献率大的请求节点.网络中所有节点的入口带宽都相同时,该算法可取得与distributed DACP2P(differentiated admission contorl)protocol算法相同的系统容量;所有节点的入口带宽不同时,该算法可取得比DACP2P算法更高的系统容量.An admission control algorithm based on peer-to-peer for streaming media was proposed. For different peers had different in-bound bandwidth and out-bound bandwidth, the algorithm chooses the requesting the biggest contributed rate peer. When all peers＇ in-bound bandwidths are the same, the system capacities that were gained by the algorithm and distributed DACp2p （differentiated admission contorl） protocol algorithm, respectively, would be the same. When all peers＇ in-bound bandwidths were not the same, the system capacity that was gained by the algorithm would be bigger than that gained by the DACp2p algorithm.
