摘　　要：随着工业物联网(industrial internet of things,IIoT)的快速发展,越来越多的应用场景对网络的服务质量提出了更高的要求。确定性网络作为一种能够提供低延迟、低抖动和高可靠性数据传输的技术,已成为未来工业互联网的核心技术之一。该文介绍了确定性网络的主要技术,包括时间敏感网络(time-sensitive networking,TSN)、无线与有线网络融合的5G-TSN和确定性网络(deterministic network,DetNet);从控制层面、数据层面和应用层面分析了确定性网络的架构,阐述了其各层次的功能与实现方式;探讨了确定性网络在电力系统差动保护、工业自动化、自动驾驶、远程医疗等领域的典型应用场景,为进一步研究和应用提供参考。With the rapid development of the industrial internet of things(IIoT),an increasing number of application scenarios are placing higher demands on network service quality.Deterministic networks,which can provide low latency,low jitter,and high reliability data transmission,have become one of the core technologies for the future of industrial internet.This paper introduces the main technologies of deterministic networks,including time-sensitive networking(TSN),5G-TSN,and deterministic networks(DetNet)that integrate wireless and wired networks.The architecture of deterministic networks is analyzed from the perspectives of the control layer,data layer,and application layer,detailing their functions and implementation methods at each level.Additionally,the typical application scenarios of deterministic networks in fields such as power system differential protection,industrial automation,autonomous driving,and telemedicine are explored,providing a reference for further research and application.
