Design And Implementation Of The Command Management Subsystem In Union Network Management System

Fast developing telecommunication industry requires excellent telecommunication network management. Well designed TMN (Telecommunications management network) simplifies management mode in the networks of multi-equipment providers, reduces telecommunication carriers' cost and plays an important role in telecom_coporation enterprises'growth.A good telecommunication management network not only is decided by the hardware system structure, more is decided by the software system structure.The work of this article is to propose UEMC(Union Equipment Management Center)system structure, and to detailed discuss design and implementation of the command management subsystem in union network management system.In the overall design of command management subsystem,combined to actual demand of command mangement subsystem,the author adopts dynamic factory pattern which is a combination of factory design pattern and reflection mechanism;And based on analysis to format file of old command mangement subsystem and reference to successful application experience of XML technology in software design aspect, specially in telecommunication software domain,this paper applies XML to command management subsystem, which will enable to fast and flexibly develop application system above it for different equipment and different management function, and reduces maintenance and development cost of UEMC. At last analyzes the advantage and deficiency of UEMC, looks forward to its prospect in the future at the same time.
