Provided are a protection switching method, a node and a control device. The method comprises: receiving an indication message including a fault confirmation time, wherein the indication message is used for indicating to perform protection switching according to the fault confirmation time; when a first path is detected to be faulty, or the fault of a second path is detected to have disappeared, starting up a timer the timing time of which is the fault confirmation time; when the timer is determined to have timed-out, re-detecting the state of the first path and the second path; and determining whether protection switching is performed according to the re-detected result of the first path and the second path. The protection switching method, node and control device of the embodiments of the present invention can effectively avoid invalid protection switching, so that the efficiency of protection switching can be improved. |
