基于网关的LVC互操作研究

摘要

Simulation architectures have achieved the interoperation of simulations in their own community and interoperation between architectures is an effective approach to interoperating multiple simulation resources.As the existing protocols,middleware and obj ect models are differ-ent interoperation between architectures is not possible.The common features between architec-tures are the basis for making interoperation possible.The mapping between obj ect models of ar-chitectures with common data exchange model is presented and the interoperation is achieved through model transformation.Finally the property of common gateway is presented after the la-tency comparison between“end-to-end”gateway and common gateway.%仿真体系结构解决了各自领域内仿真资源的互操作问题，而体系结构间的互操作是解决多种仿真资源互操作的有效方法。由于通信协议、中间件和对象模型的不同，体系结构间不能直接进行信息交互。对象模型间的相同点是异构仿真系统间互操作的基础。建立异构系统对象模型与通用数据交换模型的映射关系，通过模型转换实现各异构系统间的数据交互，最后通过“点对点”和通用网关间的时延比较，总结了通用网关的性能特点。
