摘　　要：在虚拟试验系统中,针对以太网和VMIC反射内存网不能直接通信的问题,提出了一种基于层次MAP的互操作协议方案;在引入网关节点连接以太网和VMIC反射内存网的基础上,提出了VMIC反射内存的三层内存划分方案,利用层次MAP实现了反射内存的分配和释放算法,完成了以太网数据和反射内存网数据的相互映射,从而实现了虚拟试验系统的互操作;试验表明,该互操作协议方案能够有效实现以太网和VMIC实时网之间的数据交换和共享,较好地满足了虚拟试验系统的实时性要求。Aiming at the problem that Ethernet and VMIC reflective memory network cannot communicate directly in virtual test system,an interoperability protocol scheme based on hierarchical MAP is proposed.Based on the introduction of gateway node which connects Ethernet and VMIC reflective memory network,we propose three-tier memory division scheme of VMIC reflective memory,achieve the distribution and release algorithms of reflective memory by hierarchical MAP,complete the mutual mapping between Ethernet data and reflective memory data,thus achieving interoperability protocol of virtual test system.Tests show that the interoperability protocol can effectively exchanges and shares data between Ethernet and VMIC real-time network,and satisfies the real-time request of virtual test system.
