Abstract: The present application provides a method for planning a recovery resource for resisting N-time faults and an optical transmission device, and the method includes: planning, on an optical transmission device according to preset network planning information, a recovery resource for resisting (N−1)-time faults for preset (N−1)-time faults, and the recovery resource for resisting (N−1)-time faults is an optimal recovery resource corresponding to each interrupted service during the preset (N−1)-time faults; and planning, by the optical transmission device according to the network planning information and the recovery resource for resisting (N−1)-time faults, a recovery resource for resisting N-time faults for preset N-time faults, where the recovery resource for resisting N-time faults is a network-wide optimal recovery resource corresponding to interrupted services during the N-time faults. According to the present application, recovery resource costs can be reduced, and recovery resource planning reliability can be improved.
