Flexible ethernet switching systems and methods
A switch system configured to switch Flexible Ethernet (FlexE) client services includes interface circuitry configured to ingress and egress FlexE clients; and switch circuitry communicatively coupled to the interface circuitry and configured to switch portions of the FlexE clients utilizing a cell switch and Optical Transport Network (OTN) over Packet (OPF) techniques. A method of switching Flexible Ethernet (FlexE) client services includes ingressing and egressing FlexE clients via interface circuitry; interfacing the FlexE clients with switch circuitry communicatively coupled to the interface circuitry; and switching portions of the FlexE clients with the switch circuitry utilizing a cell switch and Optical Transport Network (OTN) over Packet (OPF) techniques.
