A Method of Implementing Gateway Model Utilizing Remote Interrupts for Interworking of a Simulator with Multiple Real Systems

This paper suggests a method to implement a gateway model that enables an OPNET simulator to interwork with multiple real systems. In general, for two or more real systems to interwork with a simulator, the real systems need to be connected to a switch to form a link to the simulator. This method, however, is useful only when the models in the simulator represent the real systems that have transceivers and have no mobility. Otherwise, the method is not applicable for interworking of multiple real systems. A method to implement a gateway for the case is presented in the paper. The method includes modules that process packets transmitted via remote interrupts.
