| Abstract: | 5G puts forward higher demand for bandwidth,delay,slicing and reliability of bearer network.FlexE technology reuses the existing physical layer standard of IEEE 802.3 Ethernet,and it adds Flex Shim layer in MAC layer and PCS layer to realize network flexibility,multi-rate and rigid interface.Its functions such as bonding,channelization and sub-rate can be well docked with IP/Ethernet technology,which greatly promotes the development of 5G bearer network and guarantees the application of 5G technology.With the continuous development and improvement of 5G industry,FlexE technology will be widely used. |
