Abstract
A wavelength reallocation assisting method provides information relating to wavelength allocation to optical lines in a wavelength division multiplexing optical network in which a plurality of nodes are connected by optical fibers. The wavelength reallocation assisting method includes: outputting first allocation state information that indicates a sum of bandwidths of respective wavelength slots used by at least one of the optical lines among a plurality of wavelength slots that are available in the wavelength division multiplexing optical network; and outputting second allocation state information that indicates a maximum value of individual used bandwidths obtained with respect to the respective optical fibers, each of the individual used bandwidths indicating a sum of bandwidths of wavelength slots allocated to corresponding optical lines established in a corresponding optical fiber.
