Research on evaluation model of information transferring between heterogeneous networks in large scale virtual testing system

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.
