Research And Application Of SDH Communication Training System Based On CORBA

With the development of telecommunication and computer technology, the demand of modern information society for talent increases rapidly. Traditional system for training does not match up to the requirement of society in telecom field. It is necessary to take the network communication equipments to course for training talent. But these equipments have the same flaw, it is impossible to use the equipments for users at the same time. How to overcome the disadvantage effectively has become an important theme.The thesis is based on the research for the advantage of communication training system and related technology. It addresses and designs a model of distributed SDH transmission training system which accord to specification of RUP. It is a good method to develop an application system based on distributed technology. This system can conceal the characteristic of the equipment so as to achieve the goal of training. The research work mainly includes the following several aspects.Firstly, accord to the specification of RUP, the system is developed in the way of iteration and increment. According as business flow of the system, the requirement of system is captured and the use case is confirmed. After that, mainframe architecture and the model of the system are designed. Every function module of the system are analyzed and designed in detail.Secondly, based on the result above, the system is implemented by the middleware technology of CORBA. Accord to the research of CORBA and the characteristic of the system, the application system based on the technology of CORBA is analyzed and designed in detail. The design and implementation of the client module and server module is presented in particular.At last, the system is tested incessantly in the way of strictness and high efficiency, then the result of run is showed in the thesis and the development orientation of this system is also presented. Now, the system is used by many campuses, the feedback of these campuses is right. The fact shows that the system has a good application prospect.
