摘要
传统基于注册中心的服务使用模式难以适应恶劣的战术通信环境。为了在无中心化环境中实现服务的可靠发布和按需发现,提出了一种基于数据分发服务(DDS)的战术服务框架。基于DDS订阅/发布的通信模型优化了自组网中服务发布、寻址和远程调用的实现流程与交互机制;构建了非阻塞服务接入模型,提升了服务框架的并发访问性能。
It′s difficult for the traditional service application mode based on the registry center to adapt to the bad tactical communication environment.To realize the services′reliable publishing and on-demand discovery in the no centralized environment,a tactical service framework based on the data distribution service(DDS)is proposed.The communication model based on the DDS subscribe-publish can optimize the implementation process and the interaction mechanism of service publishing,service addressing and service remote invoking in the Ad-hoc network.A non-blocking service access model is constructed,and the concurrent access performances of the service framework are enhanced.
