哈尔滨工业大学工程硕士学位论文 哈尔滨工业大学工程硕士学位论文 Abstract 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 complex than ever. With the rapid progress of telecom network and request of service quality, the existing technology of network management cannot satisfy the requirement 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, Heilongjiang Unicom plans to develop integrated network management system, maintain and manage the network in a unified way. The characteristics of CORBA and TMN are analyzed in this article. 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 detailedly 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 relatively mature distributed object oriented technology and it is very suitable for management systems which are on different environment and different computers to fulfill the ideal link of different object. The core technology of COBRA is analyzed systematically for transport integrated network management and furthermore, the comparison and analysis among these distributed component objects standards (COBRA, DCOM and Ja
