大规模虚拟试验网间信息传输评价模型研究

Research on Evaluation Model of Information Transferring between Heterogeneous Networks in Large Scale Virtual Testing System

大规模虚拟试验系统往往需要基于异构网络环境互连的方法搭建,以满足不同试验实体间通信的实时性要求。针对不同互连方法多为经验总结、缺乏理论分析的现状,在已有的同构网络虚拟试验信息传输延迟理论基础上,建立了大规模虚拟试验系统网间实体信息传输延迟模型,定义了以实时感知度和高频感知度为尺度的大规模虚拟试验网间通信评价指标。对典型的四种实时网络与RTI跨协议互连方案分别进行分析,为具体的试验系统搭建提供依据。应用结果表明,该方法对大规模虚拟试验系统的跨协议互连方案的分析与选取具有指导意义。

To meet different real-time requirements between various testing entities, a large scale virtual testing system was constructed on heterogeneous networks environment. Aiming at the many interconnection strategies were made on experience, latency model of information transmission between heterogeneous networks was proposed; real-time perceiving level and high frequency perceiving level were defined to appraise information transferring between heterogeneous networks in the large scale virtual testing system. Four kinds of interconnection ways between real-time network and RTI were analyzed for building a testing system. The test and application show that this model is feasible for analyzing and selecting of interconnection ways in the large scale virtual testing system.
