摘　　要：针对BitTorrent(BT)系统中对等连接消耗大量骨干网络带宽导致网络拥塞的问题,提出基于网络距离度量和网络分簇的节点分配策略。仿真实验表明,在不影响BT客户端下载性能的情况下,该分配策略能够将更多的数据流量限制在网络簇内部,提高数据流量的局部性,有效地减少BT系统对骨干网络带宽的消耗。Due to large amount of backbone bandwidth consumed by Peer-to-Peer（P2P） connections in BitTorrent（BT） system, centralized management and peer-node clustering to globally manage P2P traffic is proposed. Through the network distance measurement, all nodes with their neighboring nodes are put in one group. The experimental result shows that the strategy can greatly increase proportion of local area network traffic while download time of BT is not apparently affected, and restrictions on the data flow within the local area network is a good way to reduce backbone load.
