摘要： 在P2P媒体分发网络中，当一个节点同时从若干个其他节点获取数据时，为了按时完成更多的下载任务，需要对数据下载任务进行合理调度，为此该文提出了一种基于多任务关联的数据下载调度策略，通过统筹调度一段时间内的下载任务，可有效提高系统的并发服务能力。实验结果表明该策略能提高约10%的并发处理能力。

Abstract: When a node of Peer-to-Peer(P2P) media distribution network downloads data from a number of other nodes at the same time, it needs to schedule the downloading tasks rationally in order to complete as many tasks as possible on time. As a solution for this problem, a scheduling schema based on multi-task association is proposed. By taking all requests in a period into account and scheduling them as a whole, the schema can effectively improve service performance of this system. The simulation results show that it can improve the concurrent processing capacity by about 10 percent.
