This paper analyzes the most popular Peer-to-Peer(P2P) software currently,BitTorent(BT) working methods,and finds that the content distribution algorithm makes document fragments distribute uneven among the network nodes,which impacts on the efficiency of the system. It proposes an algorithm to control the content distribution of the seeds. This algorithm can effectively avoid the document fragments to be distributed uneven in the network,so that all nodes have the similar number of fragments. This paper compares the new system with the old system from the aspects of distributed time,content diversity of the nodes and average download time of all the nodes. Simulation results show that the new system reduces the average download time and improves the robustness and efficiency of the whole system.
