摘　　要：以BitTorrent为代表的对等网络(P2P)应用已经成为最流行的网络信息共享工具,测量与分析对等网络的流量特性对于认识和提升该网络的性能具有重要的意义,如何准确地在Internet流量中识别出BT流量成为此研究的关键问题。在对BitTorrent的流量识别分析过程中,就基于应用层特征的流量识别方法进行了研究,并采用VC++工具在WinPcap网络工具包的基础上,实现了BT流量的测量系统,并根据实验结果验证了此系统的有效性。BitTorrent has become the most popular network information sharing tool,which is as a representative of the P2P applications. Measuring and analysing the traffic characterictics of P2P network has great significance in realizing and improving performance of the network. It becomes a key problem that how to indentify BT flow from Internet traffic. During in the course of studying in identify BT flow,the recognition methods based on the application layer characteristic is researched. BT flow measurement system based on VC^＋＋ and WinPcap is implemented. At last,this paper shows the effectiveness of this system based on some experimental results.
