基于DPI技术的语音视频流量监控系统设计与实现

摘要

The method of combining software and hardware is used to propose the voice video traffic monitoring system with monitoring architecture,which is based on the protocol commonly used in voice video network recognized by hardware,network protocol recognizing network complexity by software,and recognition scheme combining port,statistics and various recognition tech?nologies. The design of system architecture and related modules are analyzed in detail. The system performance was verified in the practical experiment environment. The results show that the client recognition rate of the voice video traffic monitoring system is higher than 91%,the system has no false alarm,and the recognition performance of the system can satisfy the users′requirement.%采用软硬件相结合的方法，将硬件识别语音视频网络常见的协议，软件识别网络复杂的网络协议，并结合端口、统计等多种识别技术的识别方案，提出语音视频流量监控架构的监控系统；详细对系统的架构和相关模块的设计进行分析，并通过实际试验环境对系统性能进行验证，结果表明该系统的语音视频流量监控客户端识别率都大于91%，没有误报，表明系统的识别性能可以满足用户需求。
