摘要
时间敏感网络是新一代确定性网络技术,其主要面向工业物联网,工业自动化,车载网络以及航空航天电子系统网络等安全关键领域.该技术以标准以太网为基础,扩展了时间同步、时间感知流量调度和流无缝冗余传输的能力,支持实时数据和非实时数据共网传输,可实现信息网络与控制网络的融合.本文调研了近年来时间敏感网络技术的研究现状并进行了系统的梳理和总结,首先阐述了时间敏感网络技术产生的背景和发展历程,然后对时间敏感网络的核心技术进行了介绍,包括时钟同步技术、流量整形技术、网络管理配置技术和流可靠性技术,并对当前国际上重要的企业、高校和研究机构的时间敏感网络技术相关研究成果进行了详细的分析和讨论,此外,还对时间敏感网络的仿真和应用的相关研究进行了详细分析.在此基础上,总结出目前时间敏感网络技术在实际工程应用中所面临的挑战.最后,讨论了时间敏感网络技术未来的发展趋势.
Time-Sensitive Networking(TSN)is a new generation deterministic network technology for the coexistence of the information and operation technology,which targeted to Industrial Internet of Things(IIoT),industrial automation,in-vehicle networks and aerospace electronic system networks.Time-Sensitive Networking based on standard Ethernet provides time-critical traffics with deterministic transmission services through extending capabilities of time synchronization,time-aware flow scheduling and seamless flow redundancy transmission,which enable real-time traffics and non-real-time traffics transmission can share the same network.In this paper,we firstly introduce the development history and background of TSN.Secondly,we survey the research state-of-the-art of TSN,focusing on their research topics.This survey covers three research areas:TSN core function,including time synchronization,traffic scheduling shapers,network resource management and configuration,flow reliability,TSN simulator/framework,and TSN use case study.Finally,through the analysis of these research in the three areas,research challenges and potential research directions are discussed to break the limits of TSN for real-world deployment.
