Abstract
An optical path design device includes a scheduling unit configured to generate, according to demand information, including information on a frequency bandwidth required for communication between a first node device at a start point of an optical path and a second node device at an end point of an optical path, and including information on a future time zone in which the communication will be executed, allocation content including information on a route connecting the first node device and the second node device and information on a center frequency of the frequency allocated to the communication corresponding to the demand information and determine the start time and the end time of the allocation of the allocation content, and a queue for adjusting a timing of allocation of the allocation content in the future time zone based on the start time and the end time of the allocation in a case where the allocation content cannot be allocated to the communication corresponding to the demand information with the current time as the start time of the allocation.
