一种宽带网中基于端口侦听的上网监控系统

A Watch System in Wind Bind Based on Port Interception

讨论了一种宽带网的上网监控系统（WebEye），它可以监控用户上网行为，屏蔽Internet色情、暴力等不良网站，对用户访问的目标地址（URL）进行分类，根据网站类别或关键词进行过滤；它具有很广泛的应用。从技术角度对该系统的可行性作了分析，具体分析了它的系统结构、网络结构与逻辑结构，并对各模块进行了划分并且阐述了它的实现手段。

The watch system in wind bind based on port interception (WebEye) watches the net action of user,shields the unhealthy internet Web stations,classes the URL, filtrates them based on the class or key word of the Web stations. This thesis analyses on the feasibility, relational technology, structure of the system, and puts forward the schemes of most necessary modules in the system.
