Long-Distance Exchange Of Network Management System Optimization Study And Implementation

Through years of development, long-distance exchange network capacity has been rapidly expanded and many problems are exposed in its management system, function of it's management is aged; Process capacity of it is inadequate; and both of the two defects are lagging technology development. Therefore, it is very important for China Netcom to development a set of network management system.This paper is a feasibility study on the project of long-distance network management system reconstruction. It is in-depth study focus on the interface specification and the new requirements of the network management system equipment options. This paper also developments three options on optimization of long-distance network management, and compared and verified among the three from the security, difficulty of implement, network structure, network performance other aspects It developments the eventual implementation program on solving problems in network management system's limited scope and lack of management capacity .Finally NMS improved the overall structure. According to the long-distance switching network characteristics, NMS development exchange of interface standards and solve non-standard interface problems. In addition, to improve the performance of NMS, scientific analysis and calculations on equipment selection is necessary. So after a great deal of analysis and research of outstanding works from the past experience, and the combination of long-distance exchange network status and development law By analyzing network management system database server and application server mainframe processing capability, the Treasury data through dialogue, Alarm data, log data and the statistical cycle storage cycle, the paper work out a elaborating data about NMS major equipment performance and process capability. The paper also provide proposal on equipment selection. Enhanced network management system implementation feasibility is improved.It takes one year to renovate China Netcom long-distance network management system. The NMS basically completed and achieved expected effect by the end of 2006. The NMS laid a good foundation for long-distance network' renovation. Through the implementation of the program, to a large extent, the system performance is improved and Netcom Corporation in the market competitiveness is increased indirectly. And the creation of enterprises benefits is achieved.
