Distributed Interactive Simulation Data Service Bus Management Studies

Now, distributed operational simulation which is based on network infrastructurehas become the trend of simulation development. Quality of data interaction is the keyto running system smoothly, especially during the real-time, remote and distributedsimulation. There are some reasons for low efficiency of data action, such as differentnetwork infrastructure states and a variety of transmission links； the type and quantityof service interaction request are very different； distribution of resources does not obeyparticular rules. As a result some problems occur, such as single point failure, loadimbalance, network congestion, not timely response for emergency situations and so on.In order to adapt to the complex network environment, meet the needs of large-scaleremote geographically distributed combat simulation, realize the automation of the busin the military system simulation management, can reduce the artificial control of thebus system, and can monitor the bus operation, reduce the massive military simulationcoordination difficult.The article is based on the "public platform of military information system", in thedistributed simulation is introduced, the study of distributed simulation resourcemanagement, on the basis of irm information system application requirements and thechallenges faced by the bus management, puts forward the structure of the data bus(DESB) interactive services system, bus management way and the modeling conditionsare analyzed, and on this basis, the overall structure of the bus, bus concept model is putforward, the bus management functions require automatic perception is decomposedinto resources, resource load balancing, service status synchronization, data formatunification and the bus five easy extension, on the basis of the bus managementstructure model analysis, the method of using bus management, adopt the structure andfunction of module, and discusses the management of distributed data interactive way.Combined with model platform of interactive demand, for each bus managementfunction requirements for design and analysis, and preliminary realized its functionfrom the project. Request for bus service interaction of different state, to a variety ofautomated management under the condition of test, the results showed that in thenetwork environment under the condition of complicated, link is varied, cansignificantly improve the quality of service interaction, has provided the safeguard forthe normal operation of the model of platform.In the research, fully absorb the advanced grid, cloud and SOA, RTI software architecture ideas, research results and valuable experience, considering the flexibilityand complexity of the system implementation, on the premise of guarantee the feasibleand mainly analyzes the design and implementation of bus management method.System design process, prototyping, rapid forming a satisfy the function of theprototype system. Then, a prototype of the improvement, perfect design, addingauxiliary tool, further improve the functionality and performance, formally integratedsystem. Technical implementation, will use the component-based software developmentmethods, implementation of composite component composition, from the developmentof the components to realize the management of the bus.
