SPECTRUM RESOURCE ALLOCATION METHOD AND DEVICE BASED ON FLEXIBLE GRID LABEL

摘要

The present invention provides a method and apparatus for allocating spectrum resources based on a flexible grid label, wherein the method acquires an identifier of a wavelength channel for transmitting flexible grid label information, and the flexible grid label information based on the identifier Classify each subcarrier for loading, and determine the frequency range of the wavelength channel based on the subcarrier information after classification in the wavelength channel corresponding to the identifier, and to the other wavelength channels except the wavelength channel based on the frequency range. And allocating spectral resources, and both the wavelength channel and other wavelength channels are used for transmission of flexible grid label information. According to the present invention, a solution that effectively solves a technical problem such as difficulty in determining a passage range due to a continuous problem of a subcarrier of a flexible grid passage in related technologies is solved, and information of the flexible grid label is transmitted. can do.
