<p>Embodiments of the present invention provide a synchronization method, device, and system, and relate to the field of communications, so that a device deployment cost may be reduced and the stability of device synchronization may be improved. The method includes: acquiring, by a switching node, synchronization time from a main control node; and sending, by the switching node, the synchronization time to each controlled node that is connected to the switching node, so as to perform time synchronization between each controlled node and the main control node.</p> |
