OPTICAL PATH DESIGN DEVICE AND OPTICAL PATH DESIGN METHOD

摘要

The present invention addresses the problem of a sharp increase in the time required for optical path optimization due to design parameter increases and dynamic changes in a wavelength-multiplexed optical communication network. An optical path design device of the present invention comprises: a design result acquisition means which acquires an optical path design result in which a parameter factor that is a factor each of a plurality of design parameters for an optical path could take and a characteristic value indicating a characteristic of an optical path designed using the parameter factor are associated with each other; a correlation calculation means which, with respect to one design parameter including a modified-parameter factor obtained by adding an additional factor to the parameter factor which is not included in the optical path design result, calculates a correlation between modified-parameter factors by using the modified-parameter factor as an index; and a re-design parameter determination means which, by estimating from the optical path design result and the correlation a re-design characteristic value which is a characteristic value with respect to the additional factor, determines a re-design parameter factor which is a parameter factor of another design parameter providing the re-design characteristic value.
