摘　　要：在机载分布式异构网络中,系统间的通信面临着复杂的网络环境。为了实现高效、可靠、安全的信息传输,需要通信中间件的支持。以数据分发服务(DDS)为基础,对发布订阅模型进行研究,将不同网络间的通信映射为数据分发服务中的跨域通信,引入路由服务实现跨域通信,扩展DDS原有的传输插件,用以支持不同的网络,实现了机载分布式异构网络通信中间件。通过实验对跨网络通信的时间延迟进行了测试,结果表明,通信中间件能够适应机载分布式应用的要求。In airborne heterogeneous network environment,system communication face a Complex network environments. To achieve efficient reliable and safe transformation of information,the support of communication middleware is needed. This article,based on DDS,research Publish- Subscribe model,map communication between different network into cross- domain communication in DDS,realize cross- domain communication through introducing Routing Service,extend transport plugin of DDS using to support different network,form the airborne distributed heterogeneous network communication middleware. Finally,test the network time delay of cross- network communication,indicating that the middleware can effectively meet the demand of airborne distributed application.
