The Design And Implementation Of TMN Performance Management System Based On CORBA Technology

With the opening of the telecommunication market, the relationship of network elements, telecommunication related management information, and TMN management entities is distributed logically and physically, and changes dynamically. This trait decides the telecommunication network is difficult to be managed. However, we can solve this problem with CORBA.In this paper, I first introduce the principle of TMN and the theory of CORBA, and give a schema of a uniform network element platform based on them. Then, I provide the design of the system structure, processing flow, and system reliability of the CORBA subsystem in the uniform network element platform. In the end, I describe the design philosophy and the schema of the CORBA-based performance management subsystem, and the key technology used--data collecting. In this paper, we use improved date compressing algorithm and data caching algorithm in exchanging data between front-side program and back-side program, and the upper level and lower level. These algorithms greatly reduce the size of data, improve the speed of data transport, and promise data integrity.It has been proved that this system has good stability, reliability, and is easy to be developed and maintained.In the future, the network performance management is going towards intelligence decision. I will do some search in that area in the future.
