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.
An optical network, comprising:
The optical network of Clam 1, wherein the data center node is operable to transmit the traffic on the optical ring at a receiving wavelength, and wherein each of the local nodes is operable to transmit the traffic on the optical network at one of a plurality of transmitting wavelengths that are different from the receiving wavelength.
A method for communication on an optical network, comprising:
The method of claim 13, further comprising transmitting a unique receiver mapping table to each of the local nodes prior to transmitting the traffic on the optical ring, wherein the receiver mapping table identifies a particular virtual network associated with each of a plurality of receiver tags.
The method of claim 13, wherein receiving the traffic comprises receiving the traffic from among traffic transmitted at a plurality of transmitting wavelengths, the traffic having been transmitted at a particular transmitting wavelength assigned to the local node that transmitted the traffic;
A optical communication device, comprising:
The optical communication device of Clam 14, wherein the transmitters are operable to transmit the traffic at one or more receiving wavelengths, and wherein the receivers are operable to receive the traffic at a plurality of transmitting wavelengths that are different from the receiving wavelengths.
