The telecommunication network has been providing services to the public since its emergence, and the management of telecommunication network has been very important in order to guarantee the business quality. With the development of network technology, the equipment of telecommunication network is becoming more and more diversified and complicated.
These factors determine the effective, reliable, safe and economical management of modern telecommunications networks. For this, the international Telecommunication union Telecommunication standardization sector (itu-t a T) is a standard protocol, interface and system structure of Network Management, telecommunications Management Network (Telecommunication Management Network, TMN), as the Management characteristics of modern Telecommunication Network.
Since the 1980s, ITU has been conducting interoperation of network management systems. In the process of research, it is found that the interoperation of network management system is not only a problem in the construction of network management system, but also some other problems in the construction of network management system are urgently needed to be solved. Such as the sustainable construction of the network management system, the quality of the network management system, the capacity of the network management system, the system structure of the network management system, the evolution of the network management system, the use of the network management system, etc. In addition, it is further found that each of these problems, are not exist in isolation, and other problems have all kinds of relations, studies on each problem cannot be separated and other problem, it should be in the environment of network management system for the comprehensive research, is likely to get a better solution. Based on the above considerations, the people of the main issues for the construction of network management system, unified consideration in the network environment, hope to get a comprehensive solution to the problem of the TMN is such a solution to the problem of the network management system construction.
