Application of Network Middleware in Distributed Simulation System

For simplifying the exploitation of distributed simulation experiment system, and making it stronger, more expansive, and more usable, this paper puts forward a method of making use of the network middieware in dis-tributed simulation experiment system. Firstly, the paper analyses the structure and workflow of distributed simulation experiment system, and points out that using network middleware can realize monitoring and controlling in distributed simulation experiment system. Then it expatiates the configuration and system function of the network middleware in distributed simulation experiment system according to work principle and design need of distributed simulation experi-ment system. At the same time, this paper elaborates on the mechanism of the address management, instruction per-form, news feedback and analysis module. Finally, this paper summarizes the characteristics and the developmental trend of the network middleware for making the reader understand fully the network middleware.
