Abstract: This paper proposed a new method to solve the problem of rooting hotspot. It includes the duplication selection strategy and the duplicate-using strategy. The duplication selection strategy takes the neighbor node as the duplication selection object and caculates the node performance appraisal functional value according to the node performance appraisal functional, then selects the nodes that with long on-line time, spacious belt, short network delay from the neighbor node according to the iteration algorithm. The duplicate-using strategy proposes a redirection algorithm to control the flow so as that the point will not over loading and the duplication be effectively used. The experiment uses the Java language to simulation the entire strategy. The experimental result indicated this method is effective, reliable, and is worth to promote in the present P2P network.

摘要： 本文提出了一种新的解决P2P网络路由热点问题的方法，它包括复制点选取策略和副本使用策略。复制点选取策略以节点的邻居节点为复制点选取对象，按照迭代算法，选取邻居节点中在线时间长、带宽大、网络延迟小的点作为放置副本复制点；副本使用策略提出一种重定向算法对热点进行流控，使得节点不会过载，副本被高效使用。实验采用Java语言模拟整个策略，实验结果表明该方法具有高效性，可靠性，值得在目前的P2P网络中加以推广。
