[Abstract]:The wide application of Internet promotes the development of network communication equipment. As the key equipment of communication network, router's reliability and expansibility have important influence on communication network. Modular router has high scalability and reliability due to its modular design, which is especially suitable for the current complex communication network environment. Function module is a key component in modular router, which has an important impact on the performance of modular router. Therefore, it is of great significance to study the initialization and hot-plug technology of router function module for improving the reliability of router. Based on a one-year internship experience in a well-known network equipment company, this paper studies the initialization and hot-plug technology of router function modules, and analyzes the shortcomings in the initialization process of existing function modules. A new initialization method of router function module is proposed. At the same time, the hot swapping process of the function module is analyzed, and the initialization and hot plug function of the function module are realized. The main work of this paper is as follows: 1 the initialization and hot-plug process of router function module are analyzed, and the related software and hardware technologies are studied. The key points in the software and hardware requirements are analyzed. 2 the initialization scheme of the existing router function module is analyzed to find out the shortcomings in the scheme. The initialization scheme of function module is improved from two aspects of software and hardware. A new initialization scheme of function module is put forward, and the design of the scheme is completed. The initialization scheme of the function module designed in this paper can obviously improve the startup speed of the router. 3 combined with the initialization scheme of the function module designed in this paper, the application scene of the hot plug technology of the function module is analyzed. The hot swapping function of the function module is designed and realized. 4 combining with the actual application scene analysis, the influence of initialization and hot plug on the power on the router is analyzed, and a reasonable power management scheme is designed. Realize the power management function of the router, ensure the power stability of the function module in the process of initializing and hot-plugging, To improve the stability and reliability of routers. 5 the main functions of initialization and hot-plug of the functional modules designed and implemented in this paper are tested. The final test results prove that the router function module initialization and hot-plug function designed and implemented in this paper can reduce the use of CPU resources on the main board when the function module is initialized, and accelerate the router startup speed. It also supports the power management function of routers, which can effectively improve the reliability of routers.
