Optical path design apparatus, optical path design method and program

An optical path designing method executed by an optical path design device, the method comprising:

• generating, 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, an allocation content including information on a route connecting the first node device and the second node device and information on a center frequency of a frequency band allocated to the communication corresponding to the demand information and determining a start time and an end time of an allocation of the allocation content;
• and
• 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;
• wherein the allocation content added to the queue is reallocated to a demand for the optical path,
• wherein in a case where an allocation request for the optical path is rejected, the allocation content added to the queue is reallocated to the demand for the optical path.
