摘　　要：IP路由技术最初是采用单CPU路由器,全部功能用软件实现;后来采用了在ATM网上运行IP的方法,解决了传输速度问题,并可以通过配置永久虚电路监控流量;吉(太)位线速路由交换机则在根本上解决了速度问题,由CPU运行软件及专用集成电路硬件来分别完成计算、控制等非实时任务及包转发等实时任务.现代路由技术有L2,L3,L4交换一体化及局域网、城域网和广域网技术趋同的发展趋势,线速路由交换机也将与多协议标记交换技术、密集波分复用技术结合.The evolution and development trends of IP routing technology are described in this article. Firstly, the conventional router and its limitation are introduced. Then IP over ATM is presented. After that, Gigabit ( Terabit) wire speed route switch is introduced to solve the rate problem of conventional router. Finally, the evolution and development trends of contemporary route switch technologies are analyzed .
