Abstract
A wavelength allocation device includes a decision unit, a determination unit, and an evaluation unit. The decision unit decides whether a wavelength bandwidth of an optimum route for a demand has a free bandwidth to which the demand can be allocated. The determination unit allocates the demand to a bypass route, in the case that the wavelength bandwidth of the optimum route does not have the free bandwidth in the decision unit. The evaluation unit integrates the degree of influence of a section on the optimum route, which becomes a bypass factor, based on a difference in a route cost between the optimum route and the bypass route for the demand.
