Title:
OPTICAL TRANSMISSION SYSTEM AND WAVELENGTH ALLOCATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/039965
Kind Code:
A1
Abstract:
[Problem] In a disaggregation-type optical transmission system in which bases, which have various types of transmission devices of different vendor specifications, are connected through an optical fiber, the present invention easily sets wavelength information to the transmission devices in both bases of the optical fiber so that requested wavelengths are allocated to the optical fiber. [Solution] An optical transmission system 30 is provided with at least: a facility DB 34 which stores information about an NW configuration in which prescribed wavelengths of an optical signal are allocated to an optical fiber 17; a wavelength allocation unit 32f which, when there is not, in the facility DB 34, information about an NW configuration that is identical to the NW configuration caused by the request for allocating wavelengths to the optical fiber 17 between the bases, associates, on the basis of vender information in which vender management numbers are associated with wavelengths, a management number to a wavelength that can be commonly used by different vendors, and when this wavelength can be allocated to the optical fiber 17, instructs a wavelength allocation by means of the management number; and a wavelength setting unit 33 which performs wavelength allocation setting on the transmission devices in both bases of the optical fiber 17 according to the wavelength allocation instruction.
