| Nowadays, the telecom business volume is growing, along with exponentially increase the number of telecommunications equipment, management and maintenance of telecommunications equipment are becoming increasingly complex. Therefore, how to effectively manage the growing number of devices has become a major problem for the telecommunications network maintenance personnel. Telecommunications Management Network, named TMN, plays a crucial role in solving such issues. In which, network management level and the northbound interface technology are particularly critical.As a relatively mature and complete distributed object-oriented technology, CORBA has been widely used in the telecom field now. Using its distributed object-oriented, cross-platform and extensible features, we can solve a series of problems that exist in the large-scale network management network. So this thesis chooses CORBA as the design basis of China Mobile PON Network Management System Alarm North Interface.Firstly, this thesis briefly describes the characteristics of the TMN and CORBA technology. Based on the requirements for network management alarm interface, the paper carries out a detailed needs analysis, and presents an alarm receiving plan. Then, a series of alarm interfaces, such as alarm filtering, alarm synchronization, etc., are designed. The corresponding test plan for functional test is put forward, and the test results show the correctness and reliability can be guaranteed.The design of this paper has been put into use in the enterprise and has achieved good effect. The result shows that the CORBA-based network management alarm interface can meet the requirements for the management of network equipment, and significantly improve the management efficiency of the telecommunication network. |
