Abstract
A method for distributed allocation of data paths in an optical network (100) including optical switches (30, 32, 130) connected by optical links (44, 140), includes receiving a request for a data path for connecting a source node (10) and a destination node (20). In in response to the request, one or more queries are sent, the queries corresponding to one or more candidate optical circuits that connect the source node and the destination node, the queries requesting one or more processors (230) to configure the optical switches along the candidate optical circuits to reserve optical channels on the optical links of the candidate optical circuits for the requested data path. An optical circuit is identified from among the candidate optical circuits, in which all the optical channels for the requested data path have been reserved successfully. The requested data path is established over the identified optical circuit.
