FlexE interfaces refer to FlexE clients, which correspond to various externally observed user interfaces on networks. Each FlexE client can be flexibly allocated bandwidth from a group resource pool, and the bandwidth can be adjusted. In VS mode, this feature is supported only by the admin VS.
The need for higher mobile bearer bandwidth is increasing as 5G networks continue to evolve. In addition, customers want a unified network to transmit various services, such as home broadband, leased line access, and mobile bearer services. These factors place increasingly higher requirements on telecommunication network interfaces. FlexE isolates services by isolating the bandwidth resources of interfaces. FlexE interfaces are isolated from each other so that traffic is isolated at the physical layer and network slicing is performed for services on the same physical network.
FlexE applies to the access, aggregation, and core layers. As 5G services transition through the initial, development, and maturity phases, the service volume increases gradually. FlexE allows the bearer network to be smoothly upgraded.
