摘要
工业互联网是工业4.0的关键使能技术,而网络是工业互联网的基础。首先分析了典型工业互联网业务流量类型和需求,以及时间敏感网络(TSN)和5G-U作为工业互联网网络的适配性;接着探讨了5G-U与TSN融合的4种架构模式:5G-U作为TSN的网络、链路、网桥/交换机模式,及TSN作为5G-U承载网络模式;然后研究了5G-U与TSN融合的关键技术,包括时间同步平面的融合、数据平面流量QoS框架与可靠桥接机制的融合以及管控平面的融合;最后讨论了5G-U与TSN融合的研究挑战和发展趋势。
Industrial Internet is one of enabling technologies for Industry 4.0.Networking is one indispensible technology of industrial Internet.The traffic types and communication requirements of typical industrial services were analyzed first.TSN(time-sensitive networking)and 5 G-U(5 G unlicensed)were considered as the promising wireline and wireless solutions for industrial Internet,respectively.The integration network architectures of 5 G-U and TSN were presented based on four models,which included 5 G-U as TSN networks,links,bridges/switches,and TSN as transport networks of 5 G-U.The key technologies of the integrated architectures were integrations of time-synchronization plane,data plane,and control plane.Finally,research challenges and potential research directions in the filed were discussed.
