面向虚拟仿真环境的RTI性能测试研究

针对虚拟仿真环境中RTI的性能需求设计测试指标,测试指标包括对RTI能够支持多大规模的分布式虚拟仿真进行的规模支持能力测试;属性更新延迟和交互的延迟更新;反映系统在单位时间内能够处理的最大容量的数据包的吞吐量测试;在联邦成员连续请求时间推进的情况下,RTI对其请求的响应时间的时间推进请求响应测试;联邦成员在占用一定的计算时间时,对系统其它性能指标的影响的基于盟员负载的真实仿真测试。对于上述测试指标,提出了相应的测试方案,通过对测试数据的分析比较不同RTI和盟员开发的实现方案如:RTI的体系结构、本地线程方式、数据传输的打包方式对RIT性能指标影响的定量分析,进一步提出得到满足分布式虚拟仿真环境要求的实时性RTI的技术实现方案。

RTI Benchmark Test for Virtual Simulation Environment

The Benchmark Test Index was designed based on the requirement of the performances of RTI in the virtual simulation environment based on HLA.The Test Index included the scale index of federation of the RTI support,the latency index of an update or interaction between two federates,the update throughput index between two or more federates,the time index needed to advance time a specified number of units and the index above the federate in the real load run time.The test method was designed based on the designed index system.By analyzing the Benchmark Test result data that adopted the different RTI and federate development method,such as RTI architecture,threading model and pack style of data to the performances of RTI,how the different technique impacted the performances of RTIwas got and the techniques of real-time RTI were got that met to the distributed virtual simulation environment.
