<p>Disclosed are a synchronization network clock maintenance method and device. In the above method, a query request is regularly sent to the clock units of all the devices in a network; operating state data from each clock unit is received; and a judgment is made, on the basis of the received operating state data, about whether abnormalities exist in the clock units. By way of the present invention, the following technical effects are realized: the clock performance condition of the clock units of all the devices in a network can be effectively monitored, and clock performance degradation can be communicated to the network maintenance personnel for processing before it affects a service; and at the same time, the present invention is easy to implement, only using the existing input clock signal to detect the clock performance of the clock units, and not requiring additional devices, thereby effectively enhancing the maintainability of the synchronization network clock.</p> |
