Abstract
A data center network includes a plurality of packet-optical switches each at a location in the data center network and each including a switch fabric comprising both a Layer 1 fabric and a packet fabric communicatively coupled to one or more line ports; wherein the plurality of packet-optical switches are communicatively coupled to one another in a topology to form data connectivity in the data center network, and wherein each of the plurality of packet-optical switches is configured to provide the data connectivity through the Layer 1 switch bypassing the packet fabric when the location does not require Layer 2 forwarding in the topology, and provide the data connectivity through the Layer 1 switch and using the packet fabric to provide the data service with multi-point connectivity when the location requires Layer 2 forwarding in the topology.
