Abstract: Ultra Reliable Low Latency Communications (URLLC) is the key demand of digital transformation of vertical industry, and the requirements of 5G deterministic network for Smart Grid and industrial Internet vertical industry applications are emphatically analyzed. In this paper, the key deterministic network technologies of Flex Ethernet (FlexE), Time Sensitive Networking (TSN) and Deterministic Networking (Detnet) are also studied. It is considered that TSN/Detnet is the development direction of following deterministic bearing technology.
