摘　　要：针对虚拟试验分层系统中对可靠性的不同要求,为了解决异构网络的通讯问题,借鉴了虚拟共享内存特性,分别设计和实现了反射内存网中间件VMICVSM、以太网中间件EVSM和桥接网关;结合某飞行器系统的分布式仿真试验,给出了分层网络的设计方案,对两种中间件及网关的实时传递性能进行了测试,满足了应用中不同实时性的要求。To the various requirements of Virtual Testing systems layered for reliability and in order to solve the communication problems in heterogeneous network, drawing lessons from virtual shared memory characteristics ,we designed and implemented the Reflective Memory Network middleware VMICVSM,Ethernet middleware EVSM and the Gateway Bridge. Based on a distributed simulation of aerocraft？system testing, the design of hierarchical network is given. Aiming at the two kinds of middleware and gateway, the real-time transmission performance of them has been tested, and the results meet the different application requirements m real time.
