摘　　要：提出了第三层交换技术的概念、实现过程及在网络中应用的优点,并对"交换"和"路由"在网络中不同层次的工作原理进行简述。路由器在100M以上的局域网络中进行数据转发时,极易造成网络的瓶颈,而在传统帧交换技术基础上发展起来的第三层交换技术解决了大规模局域网中各子网段之间网络信息传输的瓶颈问题,取代了昂贵的路由器,成为一种实用、经济的组网技术而得到应用。The thesis indicated the concept of third- stage exchange technology, realization process and advantages in network application. Further more, it explained the working principle of ＂exchange＂and＂router＂in different layers of network briefly. While the router is transferring data in lacal area network （LAbl） above 100M, it often results in the problem of network bottleneck. Third-stage exchange technology based on the traditional backbone network exchange settles the bottleneck problem in individual network information transferring of LAN, replaces the expensive router, and it is applied as practical and economic technology of entire network.

关 键 词：第三层交换 路由器 三层交换机
