摘要
采用数据分发服务(DDS)技术并增加组播机制,引入服务质量(Qo S)和编译式中间件技术,在DDS中采用接口本地化、可扩展传输架构等方法,对公共对象请求代理体系结构(CORBA)实时中间件通信底层进行改造,来优化和提高中间件实时性,并得到试验验证。研究结果表明,扩展后的中间件在实时性扩展(RTX)环境中传输延迟1 ms左右,实时性得到极大的提高,为实时性要求较高的大规模靶场分布式仿真试验提供了一个切实可行的新方法。
By using the data distribution service （DDS） technology, adding the multicast mechanism, importing the quality of service （QoS） and middleware compiled technology and localizing the interface in DDS, the middleware performance was improved by the transformation of common object request broker architecture （CORBA） real-time middleware communication layer with scalable transmission architecture and other methods. The experiment verified that the delay in the middleware expanded is about 1 ms in real-time extension （RTX） environment. The results indicate that real-time performance in live virtual and constructive （LVC） test is greatly improved and a new practical and feasible method is provided for large-scale distributed simulation test with high real-time requirement.
