SPECTRUM RESOURCE ALLOCATION METHOD AND DEVICE BASED ON FLEXIBLE GRID LABEL

摘要

Provided are a spectrum resource allocation method and device based on a flexible grid label. The method comprises: acquiring an identifier of a wavelength channel which is used for sending flexible grid label information; classifying, according to the identifier, each subcarrier which is used for bearing the flexible grid label information; in the wavelength channel corresponding to the identifier, determining a frequency range of the wavelength channel according to information about the each subcarriers classified; and allocating spectrum resources for one or more other wavelength channels except for the wavelength channel according to the frequency range, wherein the above-mentioned wavelength channel and the one ore more other wavelength channels are jointly used for sending the flexible grid label information. By adopting the technical solution provided in the present disclosure, the technical problems which have not been effectively solved in the related art are solved, such as the problem that it is hard to determine the channel range caused by the continuity of flexible grid channel subcarrier, thereby implementing the sending of information about a flexible grid label.
