Corba-based Middleware In Telecommunications Network Management Applications

There are so many new technologies emerge with the development of telecommunication. Traditionarily, the network management technologies TMN base on OSI protocol stack is too complex to implement, it is hard to meets the requirements of customer more and more. However, ITU-T introduces the CORBA to slove this kind of problem recently. This paper addresses how to introduce the CORBA techologies into the TMN, meanwhile, it also addresses the possible applicatioin of CORBA in TMN. Finally, this paper also introduces the detail design of how to apply a CORBA middleware TAO into Alcatel's Forth Generatioin project, using CORBA as the network management interface between the QAF and NEF, the functions in TMN.This paper especially pays attention to the detail design of the netowrk management's softweare framework, managed object class and notifciation management, try to find a more elegant design pattern in network management development.
