Abstract:
1. A method for creating a bypass in an optical network including a plurality of source nodes, a plurality of cross connect nodes (XCs) and a plurality of destination nodes, comprising the steps of: constructing a traffic demand matrix for each possible pair of combinations of the source nodes and the destination nodes, wherein the traffic demand matrix is constructed from fractional demands between each pair of the nodes and wherein, each traffic demand between each pair of nodes is normalized to a line rate R of an optical link between the pair of nodes; applying a floor operation to each normalized traffic demand to obtain the fractional demands; determining a first energy reduction metric for creating the bypass between the source node and any XC node based on the traffic demand matrix; determining a second energy reduction metric for creating the bypass between any XC node and the destination node using the traffic demand matrix; and creating a bypass that terminates at one of the XC nodes that has a largest energy reduction metric, wherein the steps are performed in a processor.
