Performance analysis for interconnection ways in complex virtual testing system

To meet real-time requirements of communication between various testing entities, complex virtual testing system is constructed base on heterogeneous networks environment. Bridge method is the main approach for HLA-DIS interprotocol connection. It solves the problems of interoperation but becomes the bottom-neck of the whole testing system. In application environment, the performance analysis method must be used to pickup the best plan out of many bridge designs. An experimental model and a mathematic model based on classical queuing theory are incorporated in the approach to make the analysis. Finally, the experiment in the interconnection of HLA/RTI and real-time network validates the study.
