Abstract: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”.
Keywords:router  daemon  embedded Linux
