<p>The embodiments of the present invention disclosed a wavelength label conflict detection method and device and a wavelength label receiving device to perform spectrum analysis on received wavelength label signals, and determine that wavelength labels conflict when judging that at least one of the following two conditions is met: there are N successive time windows in M time windows whose corresponding wavelength label signals are wavelength label signals transmitted by loading a wavelength label frequency, and the maximum different value between the amplitude values of the wavelength label signals corresponding to the N time windows is smaller than a preset amplitude threshold value, and none of the amplitude values thereof belong to a normal reference amplitude range; the maximum difference value between the amplitude values of the wavelength label signals corresponding to the N time windows is smaller than a preset amplitude threshold value, and the maximum difference value between the phase values thereof is smaller than a preset phase threshold value and none of the phase values thereof belong to a reference phase range; both M and N are integers greater than 1.</p> |
