摘要 BitTorrent是目前互联网上广泛使用的一种基于P2P的文件共享协议。它使用了动态端口,这给BitTorrent流量控制带来了很大的困难。该文在分析BitTorrent协议基础上,给出了一种基于应用层特征匹配的BitTorrent流量控制方法。首先提取出BitTorrent流的应用层特征,利用Linux的Netfilter/Iptables扩展架构实现数据包的应用层特征匹配。并利用TC实现对它的流量控制。 BitTorrent as a kind of P2P application for file-sharing is growing dramatically in recent years.BitTorrent application used dynamic port,So it become more difficult to control BitTorrent traffic.In this paper,a approach based on application level signatures,which detects and control BitTorrent traffic is described.Firstly analysis the application level signatures of BitTorrent,implement a method of detect the application level signatures of BitTorrent based on expansion of Netfilter/iptables of Linux.And implement the flow control of BitTorrent using TC.
