| Abstract: | The real-time characteristic of the LAN-Distributed Real-Time Simulation System (LDRSS) was analyzed in detail. The quantitative analysis of real-time was given and the necessary and sufficient conditions satisfying the real-time requirements were presented. The real-time performance of LDRSS was described by the defined Real-time Simulation Redundancy. The real-time characteristics of general network transfer modes, Broadcast, Unicast and Multicast were contrastively analyzed and Multicast mode was regarded as the best selection for the LDRSS. Finally, the above-mentioned theory of LDRSS was successfully applied to analyze the real-time performance of an aircraft simulation system. |
