Abstract:
1. An optical transmission device that is connected to transmission paths of a network, that performs optical communication according to a wavelength division multiplex format and that transmits optical signals over the transmission paths according to each path type that has been set to each of wavelengths of the optical signals, said path type being any one of an add, a drop, or a through for an optical signal to a transmission path to which the optical transmission device is connected, comprising: an upper limit value storage section that stores an upper limit value of the number of operational wavelengths that is the number of wavelengths to which said path types are set; an acceptance section that accepts a changing request that requests that said number of operational wavelengths be changed; and a license determination section which newly sets the changed number of wavelengths for the number of operational wavelengths if the number of wavelengths that has been changed according to said accepted changing request is equal to or smaller than said stored upper limit value.
