摘要: 由于ADSL(Asymmetric Digital Subscriber Line)端到端的通讯结构,传统的监听技术很难进行,在分析了ADSL数据承载方式和用户认证的基础上,设计了一种基于DSLAM(Digital Subscribe Loop Access Multiplexer)技术模式的监听网关。详细描述了IP数据的获取以及ATM通道的映射,实现了对ADSL用户网络层数据的在线监听。

Abstract: Traditional interception is hard to be implemented in Asymmetric Digital Subscriber Line(ADSL) because of its end-to-end architecture.Analyzing the encapsulating methods ADSL carrying network traffic and user authentication,the gateway based on Digital Subscribe Loop Access Multiplexer(DSLAM) technology is designed.This paper describes the picking-up of IP packages and the mapping of ATM channels in detail and the user’s network traffic is online intercepted.

Key words: Asymmetric Digital Subscriber Line(ADSL), Digital Subscribe Loop Access Multiplexer(DSLAM), Asynchronous Transfer Mode(ATM), interception
