摘要
为了对DVB-S中即时通信的语音流量进行监控,分析了3种主流即时通信软件MSN,QQ和ICQ的通信协议,重点研究了语音会话连接过程中的消息特征和语音数据包特征,提出了一种基于协议流程与深度包检测的即时通信语音流量识别算法,实现了对上述3种即时通信的语音流量识别。
Communication protocol of the popular instant messenger client software MSN, QQ and ICQ are analyzed in order to monitor instant messenger＇s voice traffic of DVB-S. Focusing on voice messages during the session connection characteristics and the characteristics of voice and packets, a voice traffic recognition algorithm based on protocol process and deep packet inspection is proposed. The three kinds of instant messenger＇s voice traffic identification are realized.
