Transmission Network Management System

In recent few years, with the rapid development of the telecommunication industry in China, the capacity of the telecom network is becoming larger and larger, more and more kinds and numbers of network equipments are existed in the network which makes the network more and more complex. With the rapid progress of telecom network and request of service quality, the existing technology of network management can't satisfy the require of network management and make the construct of network management system more difficult.At present, each level of network management system is isolated, which makes the circuit configuration, network guard and optimize more difficult. Based on current telecom network condition and the progress of the development of the network management system, with the demand of integrating of the network management, improving the network efficiency and reducing the maintenance cost, China Unicom plans to develop integrated network management system, maintain and manage the network in a unified way.TMN is a most commonly used network management technology and it is a good approach for the development of integrated network management system, but it does not address more detail on how to construct the management system and how to implement the interoperation among the management system. How to fulfill interface has become the most complicated problem in developing integrated network management system. CORBA is a relative mature distributed Object Oriented technology and very suitable for management systems which are on different environment and different computer, fulfill the ideal link of different object.Based on this, the most perfect integrated network management solution is the combination of TMN and CORBA, this article will take the construction of China Unicom's integrated network management system as the background andimplementation of China Unicom's northbound interface as research process, to broad the eye of development of the network management system.
