The Research of Control Technology Based on OPNET for Communication Simulation System

With the development of computer science, large-scale distributed simulation is becoming mature. As an outstanding network simulation software, OPNET can simulate on single machine. In order to be one of large-scale distributed simulation,it need to be controlled. HLA can construct new complicated simulation applications with the reusable simulation module conveniently according to communication simulation system.So it´s necessary to study the modeling of the mechanism and the simulation based on the steps. The Controller and OPNET federates is proposed. The parameters of OPNET can be changed and the federation time can be advanced.Simulation results verify that the method is feasible, the method could make contribution to construct the large-scale military simulation applications.
