Flex ethernet technology and application in 5G mobile transport network

With the advent of 5G era, the rise of cloud services, virtual reality/virtual reality (AR/VR), vehicle networking and other technologies has put forward new requirements for the bandwidth and delay of the bearer network. Traditional Ethernet technology cannot meet the new requirements very well. Flex Ethernet (FlexE) technology has emerged as the times require. This paper introduces the background, standardization process, functional principle, application mode and technical advantages of FlexE technology, and finally analyses its application prospects and shortcomings in 5G mobile transport network.
