Abstract


With the ALL-IP business development, packet transport network is gradually replacing the current mature SDH network , the backbone network in the major role to play wider , to larger commercial stage . Packet transport network compared to traditional transmission network with better QoS guarantee , richer OAM management , more reliable protection, better able to improve network reliability , in particular the protection function is designed for the network operation and maintenance and high-quality services provide a guarantee. While improving network management system development and design , to more efficient network equipment monitoring and maintenance to ensure the normal operation of the network and equipment , to provide users with a simpler and more friendly operation and services. This paper analyzes the advantages and disadvantages of various software development framework , selection will be based on J2EE three-tier C / S architecture applied to the NMS system . After a detailed analysis based on this architecture firm level - subnetwork layer - Multiservice PTN network management system design ideas, the system is divided into different levels , and with reference to TMN model of the system function modules specific and detailed design partitioning , identified NMS system possess management functions . This article also discusses in depth at all levels of the specific design and development, analysis of the various levels of communication mechanism design ideas, and briefly describes several key technologies in the system specific application layers , gradually refined network management system development . Protection is a packet transport network survival function, so the network management system in perfect protection function is particularly important , this article will focus on the protection of design and implementation. In this paper, based on equipment needs , focusing on analysis of the LAG protection , MSP protection and LSP protection mechanism to protect these three characteristics, and made ​​reference to the network management system -level design of these three protective mechanism design. After the design ideas for the front , SBI layer from the client to complete all levels of the specific code, and shows the network management system to run and test results. Finally a summary of the entire study proposed system deficiencies.
