| 摘 要： | 为提高现有BT流量识别技术的准确性，通过分析BT协议和BT实际传输数据，找出BT传输过程中必会出现的各种固定字串，以之作为特征字串，从而利用增加特征字串个数来提高识别准确性。实验表明，对比现有的技术，该方法能提高识别的准确性，克服因未捕获握手包而无法识别数据流的缺陷。

| Abstract: | To enhance the accuracy of the existing technologies for identifying BitTorrent (BT) traffic, the fixed strings that appeared in BT transmission process without failure were found out by analyzing BT protocol and BT transmission data, and set to be characteristic strings, consequently enhanced the accuracy by increasing the number of characteristic strings. Compared with the existing technologies, the method can enhance the accuracy of identification and overcome the limitation that data traffic cannot be identified because of missing hand-shake packet. |

| Keywords: | network traffic protocol identification characteristic string |
