摘要： 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.

摘要： A Flexible Ethernet (FlexE) switch system configured to switch a FlexE client service includes interface circuitry configured to ingress and egress a plurality of FlexE clients; and switch circuitry configured to switch portions of the FlexE clients based on 64 b/66 b block boundaries between the interface circuitry. A node configured to switch a Flexible Ethernet (FlexE) client service in a network includes one or more line cards configured to ingress and egress a plurality of FlexE clients; and one or more switch fabrics configured to switch portions of the FlexE clients based on 64 b/66 b block boundaries between the one or more line cards.

摘要： A switch system includes interface circuitry configured to ingress and egress clients each including a stream of encoded blocks; and switch circuitry configured to switch the clients between the interface circuitry based on block boundaries of the stream of encoded blocks. The stream of encoded blocks can include 64 b/66 b encoding. Each block in the stream of encoded blocks can be switched intact.
