CORBA Navigator, A Versatile CORBA Client and its application to Network Management
Taichi Yata, Kouji Iwashita · 2003
We have developed the versatile CORBA client that we call CORBA Navigator. CORBA Navigator can instantly access any CORBA server, and its access (operation) order can be specified by a UML diagram. CORBA (Common Object Request Broker) is being widely used in a variety of fields. It is playing an important role in telecommunication management. The international standards for telecommunication management used to be based upon CMIP (Common Management Information Protocol). However, CORBAbased telecommunication management standards are now emerging. Unfortunately, CORBA is still too complex. For the network carrier companies to adopt an CORBA-based EMS (Element Management System), it is important to have the tools that provide easy access to the CORBA-based EMS. Existing client systems are EMS specific and so are rather inflexible. In this paper, we describe the features of CORBA Navigator, show what prevents the realization of versatile CORBA client, and how we solved these problems. We also show how we applied the CORBA Navigator to the new telecommunication management standard for B-PON (Broadband Passive Optical Network), which adopts CORBA and UML.
