Title: METHOD AND SYSTEM FOR ASSIGNING RESOURCES IN OPTICAL TRANSPORT NETWORKS
Abstract:
The proposed invention is in the area of managing resources in optical transport networks, for example in the area of in-operation media channel format and spectrum management. For this purpose, the type of Media Channel Format is determined for each of a plurality of candidate paths, wherein each candidate path connects a pair of nodes in an optical transport network. Then, the expected weight describing traffic volume of each of the candidate paths is determined, and a spectrum share is assigned to each link of each of the candidate paths based on the determined Media Channel Formats and determined weights. In this way, spectrum shares assigned to different links and candidate paths can be used for efficiently assigning a band spectrum to each of the Media Channel Formats of the candidate paths.
