摘要： 音视频类型的应用程序是应用市场中下载的热点,针对传统互联网的协议识别技术已经相对成熟,但对于移动网络中的音视频应用的识别研究还刚开始受到关注,通过对此类应用识别,运营商可以收集用户在线观看音视频等行为习惯,进而为提供用户差异化服务,也可以服务于对应用的安全审计。文章主要研究了移动互联网音视频类协议识别技术,从对应用协议数据的分析中获取应用特征值,利用特征值实现协议识别;通过开发识别程序和大量实验,实现了对移动互联网音视频类协议的自动识别,并进一步提高识别的准确率及效率。

Abstract: The Audio-Video(AV) type apps is a hot topic in app markets. Comparing with the traditional Internet protocol identification which is thoroughly studied, studying AV protocol identification in mobile network is preliminary. Carriers can provide differential services and security profiling by recognizing different apps from collected users’ online watching behaviors. In this paper, we study the protocol identification technology for AV apps in mobile network. We get application signatures through protocol payloads. The obtained signatures are used to classify protocols. By setting up a large number of experiments and developing identification programs, I proposed a new method that can automatically identify AV protocols in mobile network. In addition, the accuracy and efficiency are further improved.
