摘　　要：本文基于一种广电网络IP化检测系统整体架构,通过对系统中采集现有网络数据的不对称性成因进行分析,提出一种利用同源同宿处理的深度分组解析(DPI)识别技术对报文进行分组级整包分析、流级别还原、内容级筛查。实现检测系统内针对终端和用户标识、业务流量特征的精确识别与控制,以及实现信息保障能力,为广电网络的运营维护提供技术支撑。Based on an overall architecture of IP-based detection system for radio and television networks,this paper analyses the causes of asymmetry in collecting existing network data,and proposes a method of packet analysis,stream restoration and content screening using homology processing based deep packet analysis(DPI)identifcation technology.Accurate identifcation and control of the terminal and user identifcation,traffc characteristics and information support capability are realized in the detection system,which can provide a reference for the system analysis in the network operation.
