OTN transport over a leaf/spine packet network

Abstract:

A network element (16) includes ingress optics (22) configured to receive a client signal; egress optics (30) configured to transmit packets over one or more Ethernet links (20) in a network (12); circuitry (26, 28) interconnecting the ingress optics (22) and the egress optics (30), wherein the circuitry is configured to segment an Optical Transport Network (OTN) signal from the client signal into one or more flows; and provide the one or more flows to the egress optics for transmission over the one or more of Ethernet links (20) to a second network element (18) that is configured to provide the one or more flows into the OTN signal.
