Research And Implementation Of Accounting In Network Management System Of Broadband Multimedia Satellite Network

With the rapid development and application of spaceflight technology and information technology, satellite network plays a more and more important role in politic, economy and military area. The relationship between satellite system such as meteorological satellite and our life is closer and closer. In this situation the new generation broadband multimedia communication satellite system emerge as the time require, the civil communication satellite project is an important one in the" Eleventh five" year plan. Because of the special network element and operating characteristic, traditional network management technology isn't applicable. To ensure that the system work autonomic and efficiently and the information can be transferred safely or dependably, the research of broadband multimedia satellite network management system has to be done. At the same time, to ensure that the rational utilization of network resources and take into account the interests of consumers and operators, the research of accounting management has to be done.In the paper, Accounting management is divided into accounting on ATM and accounting on operation. By analyzing and discussing the existent common accounting scheme, for this two kinds accounting, we emphatically research on the following three aspects:accounting scheme, data collection and accounting management. This paper proposes accounting formula and accounting scheme for user based on the QoS strategy on the layer of ATM. To each multimedia operation that multimedia communications satellite emphatically supports, we also make a relative reasonable accounting strategy based on each operation characteristic combined with common broadband network accounting method. Finally, we design and accomplish the broadband multimedia communication satellite accounting center platform. This platform implemented the following functions:system management, accounting on ATM, accounting on operation, statistics analysis and self-service management. All the function has tested in network management system simulation platform, the result show that accounting center is user-friendly, easy to operate and function is perfect.
