Communication route allocation device, communication route allocation method, and program

A communication route allocation method comprising:

• extracting connectable possible routes on the basis of utilization condition information of a network from among optical path routes connecting start points to end points of optical paths accommodating communication demand in the network;
• selecting a core, a link, and an optical path route to accommodate optical paths by leveling wavelength utilization conditions over the entire network on the basis of utilization condition information of multicore fibers of all links in the network or the possible routes, the wavelength utilization conditions being the number of wavelengths arranged for each core on a multi-core erbium-doped fiber amplifier (MC-EDFA);
• and
• selecting a wavelength to be used for the core, the link, and the optical path route that have been selected.

A non-transitory computer readable storage medium storing a program that causes a computer to function as a communication route allocation device comprising:

• a route possibility extraction unit configured to extract connectable possible routes on the basis of utilization condition information of a network from among optical path routes connecting start points to end points of optical paths accommodating communication demand in the network;
• a core selection unit configured to select a core, a link, and the optical path route to accommodate the optical paths by leveling wavelength utilization conditions over the entire network on the basis of utilization condition information of multicore fibers of all links in the network or the possible routes, the wavelength utilization conditions being the number of wavelengths arranged for each core on a multi-core erbium-doped fiber amplifier (MC-EDFA);
• and
• a wavelength selection unit configured to select a wavelength to be used for the core, the link, and the optical path route selected by the route possibility extraction unit and the core selection unit.
