Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for configuring a clock time synchronization source. Background technique [0002] With the rapid development of network informatization, the network composed of a large number of devices is getting larger and more complex. Corresponding to the network scale of hundreds of node network elements, the clock time synchronization source configuration of a single network element can no longer meet the requirements of the project. Applications, especially when the network is very complex, require simple and efficient clock time configuration. [0003] In related technologies, in the network operation, a manual single network element is generally used to configure the clock time synchronization source point by point. As the number of clock transmission link network elements is limited, the clock time network needs to be carefully planned, and special attention is a...
