An optical switch for a network having a plurality of nodes, includes a switch coupled to communications links used for input and output in which a plurality of wavelengths are used to carry traffic on a communications link, and a controller, coupled to the switch, for controlling the operation of the switch by implementing a routing protocol, and implementing a labeling protocol to associate a wavelength with a route table destination. The controller controls the switch to direct the various wavelengths of traffic from an input link to an appropriate output link as determined by the routing protocol and the labeling protocol. |

DETAILED DESCRIPTION In view of the foregoing problems, drawbacks and disadvantages of the conventional systems and methods, an object of the present invention is to provide a system and method for eliminating much of the processing of the data on the path through a router.
Another object is to eliminate all of the electronics (or at the very least significantly reduce the electronics) on the data path so that an "electronic bottleneck" is avoided and the capacity of the optical fiber can be advantageously exploited.
In a first aspect, an optical switch for a network having a plurality of nodes, includes a switch coupled to communications links used for input and output in which a plurality of wavelengths are used to carry traffic on a communications link, and a controller, coupled to the switch, for controlling the operation of the switch by implementing a routing protocol and implementing a labeling protocol to associate a wavelength with a route table destination.
The controller controls the switch to direct the various wavelengths of traffic from an input link to an appropriate output link as determined by the routing protocol and the labeling protocol.
In a second aspect, an optical switch for a network having a plurality of nodes, includes a switch coupled to communications links, which the switch can use for input or output, on the communications links a plurality of wavelengths existing representing traffic thereon, and a controller coupled to the switch for controlling an operation of the switch by implementing a routing protocol and exchanging routing information with other nodes, implementing a network protocol and forwarding the traffic to a next hop, and implementing a labeling protocol to associate a wavelength with a route table destination.
The controller controls the switch to connect the various wavelengths of traffic on an input link to an appropriate output link.
Further, the invention provides a network incorporating the inventive switch, a method of communicating, and a signal-bearing medium storing the inventive method
