Abstract
The present document discloses a method and a system for restoring an optical layer service. The method includes: determining wavelength resource occupancy information of an inner-link of the node and an optical layer link where the node is located; herein the wavelength resource occupancy information includes resource occupancy state information of a wavelength resource corresponding to a Hold Priority; and flooding the wavelength resource occupancy information in a network where the node is located.
