【Abstract】 In recent years, with the rapid development of satellite application technique, satellite network building projects have been widely applied in many fields and play an important role in both military and civilian communication. In the study field of satellite communication, the important research contents are how to choose technologic system of satellite communication, to define available operations and entrance modes of operations, to program satellite resource application strategy, and to ensure quality of service. Based on some satellite communication network project, the problem of how to design and realize the network administration and control system for a full-IP application satellite communication system is studied and discussed.According to the actual demand of the project, the network administration and control system for some FDMA/DAMA satellite system is mainly studied in this paper. To connect into the network administration and control system, all of the actual operations are all IP mode. In this paper, the available collectivity frame scheme for the network administration and control system is provided, and the basic working flow of the system and the key techniques are analyzed. The main content of this paper is outlined as follows:(1) The function architecture on both the network control system and network administration center is studied and discussed. The design of network administration and control system is provided;(2) The key techniques about how to realize the system software are analyzed. The application ensureness technique is discussed for Pure-ALOHA system, and the simulation test is given.(3) The user-machine interface software of network administration center is designed and realized, which satisfied the application requirements for the network administration and control system.The network administration and control system is studied and discussed in this paper. It has been tested under the strict conditions. The results show that the system can run steadily and reliably. The research in this paper can provide some stated ideas and consultable experience for future similar system’s design and realization.更多还原
