Provided are a method, system and device for managing an optical layer in a wavelength-division network. The method comprises: determining, by a device in the wavelength-division network, whether a performance value in a subnet for indicating a service performance of a service exceeds a threshold corresponding to the service performance; and if so, adjusting, by the device, the performance value to be less than the threshold. The present invention addresses the problems of low management efficiency and poor reliability of an optical layer in a wavelength-division network, thus increasing operation and maintenance efficiency and reducing the cost. |
