IP路由器体系结构分析及其发展趋势

作者对路由器的逻辑体系结构进行了深入分析,指出构成路由器的三大模块是:网络接口模块、搜索引擎模块和协议配置与控制模块;重点分析了路由器体系结构发展过程,对目前的六类体系结构进行了较为详细的分析;指出路由器的结构已由基于软件的共享总线式的特殊计算机逐渐发展威为基于硬件的多总线或交换背板式的交换式的路由器.

Analysis and Development on Architecture of IP Router

The writer analyzes the logic architecture of router and makes a point that the router is made up of three models: net interface model, searching routing model and configuration and control model. The process of architecture of router has been discussed deeply and six kinds of typical architectures have also been presented. The developing tendency of router has been drawn a conclusion .
