METHOD OF ALLOCATING WAVELENGTH AND WAVELENGTH ALLOCATION DEVICE

摘要

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.

1. A method of allocating a wavelength, the method comprising:
deciding whether a wavelength bandwidth of an optimum route for a demand has a free bandwidth to which the demand is able to be allocated; allocating the demand to a bypass route when the wavelength bandwidth of the optimum route does not have the free bandwidth; and integrating the degree of influence of a section on the optimum route, the section not having the free bandwidth, based on a difference in a route cost between the optimum route and the bypass route for the demand.
