摘要

摘要: 为了对TCP数据流进行及时、快速并准确的识别,本文提出一种TCP流量早期识别方法. 该方法以TCP流初期的3 个数据包的载荷大小和服务器端口作为特征,利用支持向量机进行分类. 实验结果表明,根据提取的特征,采用无偏训练样本能快速而有效地识别WEB、MAIL、P2P中的BitTorrent和eMule等流量.

Abstract

In order to identify classification quickly and accurately, an early traffic classification method (ETCM) is proposed. The method uses the payload size of three early packets and the server port number obtained from the TCP flow as flow feature, and classifies the traffic based on support vector machine (SVM). The results show that ETCM meets the following conditions: extracted features used, training samples selected without bias, Internet traffic related to WEB, MAIL, BitTorrent and eMule can be identified efficiently and quickly.
