Information exchange between heterogeneous systems based on extensible layered architecture

Large-scale distributed real-time simulation environment is needed in the background of joint test and training. Simulation architectures focus on interoperability modeling and reuse except real-timing and scalability, so they cannot meet the requirement of real-time simulation systems. Layered simulation architecture is presented based on data distribution service (DDS), which can boost the performance of real-time simulation systems. The mapping relationship is set up between latency simulations, the exchanged information and data centric-publish-subscribe (DCPS) entities, based on which publish/subscription is rebuilt to realize the data exchange between simulation systems. DCPS defines that the publish/subscription relationship can be specially built between the publishers and subscribers belonging to the same data space. The information exchange is done using the Domain bridge through topic mapping, which improve the performance and scalability of the simulation architecture. Finally, the relationship between the mapping model and the performance of the real-time system is found and the function of the Domain bridge is validated, through two prototype systems testing. ©, 2015, Chinese Institute of Electronics.
