An Efficient Naming Service for CORBA-based Network Management

There have been growing research interests for the realization of CORBA-based network management system for telecommunication network, and several methods have been devised to apply CORBA technology to telecommunication management network. We concern about the pure CORBA-based network management system. In this system, there is no conventional CMIP agent in a managed system. Otherwise, a managed system contains CORBA-based managed objects with which CORBA-based managing objects interact and perform the management task. To represent the containment relationship between CORBAbased managed objects in a managed system, naming tree is used. To form the tree, CORBA naming service is utilized. However, OMG’s CORBA naming service requires the entire CORBA-based management objects to be instantiated at all the time. Since network elements usually do not have sufficient system resources, the applications running on them may experience severe degradation in performance. In this paper, we design a new CORBA naming service. By modifying the OMG’s naming service and adding an IDL definition for the new naming service, it can efficiently construct a naming tree without instantiating all the managed objects all at once. CORBA IDL is defined for the new naming service, and performance of the implementation is evaluated to demonstrate its efficiency.
