摘要
分析了BitTorrent文件共享系统的工作流程,指出了在种子节点选取和连接方式上的缺点。介绍了网络定位技术GNP,详细分析了GNP的工作流程,说明了它在网络中定位主机的优越性能。提出了一种S-RTT策略,进行种子节点选取和连接。将此策略引入BitTorrent文件共享系统中,使得BitTorrent系统能够灵活选择优质的种子节点、控制信息流量,有效改善了BitTorrent网络性能。
In this paper, we analyzed the workflow of BitTorrent file-sharing system, and pointed out the shortcomings in ways of choosing and linking seed. The GNP technology was recommended, its workflow was analyzed in detail, and the superiority of it was shown in locating mainframe. This article described one kind of BitTorrent file-sharing model based on S- RTT strategy that led S-RTT strategy into BitTorrent system. It enables BitTorrent system to choose the good seeds flexibly and control network flow, and improves the network function of BitTorrent system effectively.
