A set of media channel (MCh) widths is determined for an optical network. Based on a topology of the network, a first set of original MCh widths are computed for tentative use in the optical network, the first set of original MCh widths defining a target spectral efficiency. A reduced set of new MCh widths are generated from the first set of MCh widths by respectively mapping each of the original MCh widths of the first set of original MCh widths to a corresponding, or respective, new MCh width. An optimization algorithm is used in an example embodiment to facilitate the mapping.

Method and system for media channel format set management in optical transport networks

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.
