Abstract: The present disclosure provides a clock synchronization method and a clock synchronization apparatus. Herein the method includes: a physical layer device acquires a synchronization message used for a device to be synchronized to implement clock synchronization; and the physical side device transmits the synchronization message to the device to be synchronized. By means of the abovementioned technical solution provided by the present disclosure, the problems of small user capacity of the load and high synchronization cost resulted from the clock synchronization method in existing technologies are solved, the insufficient user capacity of the load caused by the limit of the CPU architecture is avoided, and the bandwidth resource of the Ethernet is utilized to the maximum extent.
