The Design And Implementation Of CORBA Based Distributed VOIP Configuration Management

With the continuous development of telecommunication informalization, a large quantity of equipment supplier have developed the own Element Management system, which have greatly prompted the level of OSS informalization. Traditional Element Management system mainly adopts 2-tier architectur(eC/S model). C/S model is a good method to build software system in a specific and independent environment,but with the enlargement of EMS and the request of Internet development, nowadays the software architecture of the enterprise management information system is distributed multitiers software architecture.The thesis is according to the development of the high requirement and the new technology of the NMS, put forward and designs a model of distributed integration Network Management Configuration System, set up a distrituted, Object-Oriented network configuration management modue.The main innovation is to design and implement Network Management Configuraiton System, which is based on CORBA,Object-Oriented and distributed,and modularize the function block inside the system according to the softbus idea, which makes the module become a standard component and furthermore make it easier to reuse in the other network management CM system. The thesis mainly analysis the character of the structure and function of the system, set up a integrated solution, implement the design of the distributed system, MO manager module and Adapter module. Based on the idea of high congruence and loose coupling, it adapt stadard IDL definition between module interfaces.Secondly, based on the distributed CORBA platform, by POA realizing the object distributed request, the thesis give an abstract data module of the network element, and describes the data structure by using IDL, which is usefull to other network data module.Lastly, fully considering the SNMP's advantage of being widely supported, the thesis puts forward a kind of Network Management framework based on CORBA/SNMP adapter, who transfers the SNMP language into IDL in CORBA, by using the map between the SNMP and CORBA.The method will provide a solution for unifying the interface in Network Management.
