[Abstract]:With the rapid development of modern computer networks, the performance, stability, reliability and power consumption of routers are becoming more and more important. In the construction of special network in some areas of our country, the router based on special network is more demanding. The router based on special network should not only meet the high performance requirements of ordinary router, but also meet the special interface. Multi-network convergence, routing optimization, integrated services and other aspects of the requirements. Aiming at the above problems, this paper focuses on the design and implementation of router based on special network. Based on the research on the theory and technology of routers, the key technologies in the design and implementation of routers based on special network are discussed and studied in detail in this paper. The following article mainly completes the content: 1. In order to solve the problems of high-speed radio access, ultrashort wave radio and short-wave radio access, the high-speed radio access technology and the radio access technology are studied, and the solutions are put forward. In order to solve the problem that routers based on special network realize channel transmission via radio station and narrowband cable, the transmission capacity is very limited, and the network is prone to congestion, which leads to the network communication becoming unreliable, end-to-end delay, jitter and packet loss rate increasing. A two-stage flow control method based on rate flow control is designed. The router scheme based on special network is designed, some hardware design methods are explored, the circuit schematic design of router based on special network is completed, and the design of PCB is realized. The programmable logic design of router based on special network is completed, and several system design methods of programmable logic are put into practice. The design and implementation of some software of router based on special network are completed, and the integration debugging is carried out. Finally, the router based on special network has been tested on single machine and multi-unit network, and the test results have been obtained. Through the test results, the router prototype based on special network has completed the task of this paper. The function and performance of router based on special network are realized. Among them, the pass rate of function and performance index is 100 and the power consumption is reduced to 9.6 W. The router prototype based on special network can provide the functions of integrated networking, routing optimization, access control, equipment interconnection and so on, which meets the requirements of special network.
