The Application And Research Of Distributed Interactive Simulation's Common Infrastructure

The distributed object technique is one focus of software development. Using this technique, the developer can realize the transparent call between the objects that are on different computer without thinking about the network communication, then the object oriented technique can be used to design the distributed system. The most widely recognized specification are COM and CORBA, they both have widely support, they have been successfully used in Client/Server application and internet application. In simulation system, with the coming up of High Level Architecture (HLA), the distributed object technique play more and more important role, its runtime infrastructure is usually developed under CORBA specification.The project background of this paper is the simulation of ship campaign system, it is a special DIS system. As an ripe specification of component object interact, COM play an important role in Windows抯 desktop application. This paper apply COM technique to the simulation of ship campaign system抯 command console and make it as an common infrastructure of the distributed interactive system. Based on the infrastructure the application can realize the transparent interact between different computer抯 object. In the end of the paper, the writer applied this method to the whole simulation system and put forward an design scheme, and then analyzed the problems of the scheme.
