Abstract
An optical network includes an optical ring, a plurality of local nodes, and a data center node. The plurality of local nodes are coupled to the optical ring and each local node is capable of receiving traffic from a local client and associating a transmitter tag with the traffic. The transmitter tag identifies a virtual network of the local client. The local node is further capable of transmitting the traffic on the optical ring. The data center node is also coupled to the optical ring and is capable of receiving traffic transmitted by one of the local nodes and determining a receiver tag for the traffic, based on the transmitter tag associated with the traffic and the local node that transmitted the traffic. The data center node is also capable of associating the selected receiver tag with the traffic and transmitting the traffic on the optical ring.
