摘　　要：文章介绍了嵌入式Linux下的路由器数据链路层子系统的设计原理。该系统利用守护进程对路由器数据链路层功能进行管理和维护,并采用软硬件相结合的方案实现与其他进程的通信接口。克服了传统开发方式系统性不强的缺点,并具有维护灵活、扩展方便的特点。该实现已应用于高速宽带路由器的研发项目中。An sub-system of the data link layer in the router is introduced.The design and implementation in the embedded Linux are analyzed.The sub-system makes use of the principle of the Daemon to maintain and manage the function of the data link layer in the router.The realization of the system takes the advantage of the cooperation of the software and the hardware.It overcomes the shortcoming of the traditional development methods that are systemless and has the characteristics of flexibility and scalability.This scheme has been adopted by the project“Research and Development of High-speed Broad-band Router”.
