摘　　要：针对复杂虚拟试验分层实时系统中对实时性、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;结合某导弹系统的分布式仿真试验,给出了分层实时网络的设计方案,对两种中间件及网关的实时传输性能进行了测试,满足了应用中不同实时性的要求。To the various requirements of Complex Virtual Testing real-time systems layered for real time, 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 missile system testing, the design of hierarchical real-time network is given. Aiming at the two kinds of middleware and gateway, the realLtime transmission performance of them has been tested, and the results meet the different application requirements in real time.
