Corba-based Multi-protocol Adapter Gateway Design And Implementation

The rapid development of the third-generation mobile telecommunication technology has taken revolutionary challenge to telecommunication network management. The TMN integrated network management system based on CORE A will surely make key action for the telecommunication management's conversion to be open and distributed, resolving diverse network management system's intercommunication, and making foundation of interconnection and interoperation among diverse network management system.The TMN integrated network management system based on CORBA is essentially a typical distributed and heterogeneous system. It provides the exchange and share of information, unified performance and fault management, etc. Consequently, we designed a multiple-protocol adapter gateway system based CORBA, which provides a uniform CORBA interface to upper layer.Multiple-protocol adapter gateway deals with two critical technologies: Interface information model definition and gateway's architecture. Interface information is the key of improving interoperation of a standard network management frame and information exchange capability among network management system of different equipment provider. This system used CORBA/IDL describe the information model, and implemented the intercommunication among information model of different management frame. As for gateway's architecture, this system makes full use of CORBA technology and common object service in distributed environment to complete every object naming in information network management supported, and notification filtering function rather than redefine the interface in next use, and which make information model more simple, even with interoperation; through analyzing the existing design pattern in multiple-protocol adapter technology, we not only summarized the common characteristics and nomal architecture, but also abstracted the idea in these innel law, and formed a set of supported service that can be reuse in network management software; deeply researched ACE striding platform mechanism, implemented striding platform function of multiple-protocol adapter gateway, and provided strong theory foundation and rich practicing experience. This thesis explains detailedly how to build flexible frame architecture of multiple-protocol adapter gateway and a reusable development platform.
