机载时间敏感网络关键技术研究

Research on Key Technologies of Airborne Time sensitive Network

现有的机载网络受限于特定协议与支持的信息流种类,难以为航空电子系统提供混合安全、灵活配置的多业务通信服务统一网络,应运而生的时间敏感网络能够满足下一代航空电子系统网络的发展要求。针对下一代机载网络需求,对时间敏感网络进行研究,主要从时间同步、流量调度、可靠性提高和网络配置四个方面进行了论述,重点阐述各个关键技术的解决方法,为研发下一代时间确定性、低传输延时、高可靠性和高安全性机载网络提供了可借鉴的技术途径。

The existing airborne networks are limited by specific protocols and supported information flow types,so it is difficult to provide a hybrid,secure and flexible multi service communication service unified network for avionics system.The time sensitive networks emerged at the historic moment can meet the development requirements of the next generation avionics system networks.In view of the next generation of airborne network demand,this paper study of time sensitive network,mainly from the time synchronization,traffic scheduling,improve the reliability and the network configuration has carried on the elaboration from four aspects,expounded the key technology solutions,to develop the next generation time uncertainty,low transmission delay,high reliability.
