PROBLEM TO BE SOLVED: To provide an accommodation determination device for determining accommodation of a path by a subband in an optical communication network using an optical signal including a plurality of subbands.SOLUTION: An accommodation determination device comprises: determination means for determining presence of optical signals able to accommodate a path from a starting point of the path sequentially; and determination means which, when the determination means determined that there is not an optical signal able to accommodate the path, sets a new optical signal in a section between an endpoint of an optical signal able to accommodate the path at the last and an endpoint of the path, and determines to accommodate the path. |
