Title:
METHODS FOR CREATING BYPASS IN OPTICAL NETWORKS
Document Type and Number:
Japanese Patent JP2012142933
Kind Code:
A
Abstract:
To provide methods for determining energy efficient routes in optical networks.
An optical network includes multiple source, cross-connect (XC), and destination nodes. A traffic demand matrix is constructed for each possible pair of combinations of the source nodes and the destination nodes. A first energy reduction metric is determined for creating a bypass between the source node and any XC node based on the traffic demand matrix, and a second energy reduction metric is determined for creating the bypass between any XC node and the destination node using the traffic demand matrix. Then, a bypass that terminates at one of the XC nodes that has a largest energy reduction metric is created.
