摘　　要：随着网络技术的发展,三层交换机开始取代路由器,成为内部网完成三层转发的核心设备。介绍了千兆三层交换机SW1200软件系统的设计。首先介绍了SW1200的硬件结构和软件平台,接着采用网络层次模型分析系统的软硬件关系,给出软件系统框架的设计,最后论述框架内各个功能模块的设计,重点是实现三层交换的核心驱动和三层任务。With the development of network technology, layer3 switches have taken the place ofrouters in intranet as devices performing layer3 forwarding. The software system of SW1200, a gigabit layer3 switch is introduced. At first hardware structure and software platform of SW1200 are presented. After analyzing the relationship between hardware and software using network layering model, the architect of software system was given. Finally, all the software components were discussed and the emphasis was focused on the core driver and layer3 tasks which realized layer3 switching.
