Description

technical field [0001] The present invention relates to the field of communication, in particular to a clock time synchronization source configuration method and device. Background technique [0002] With the rapid development of network informatization, the scale of the network composed of a large number of devices is becoming larger and more complex. Corresponding to the network scale of hundreds of nodes, the configuration of the clock and time synchronization source of a single network element cannot meet the requirements of the project. Applications, especially when the network is very complex, require a simple and efficient clock time configuration. [0003] In related technologies, during network operation, a manual single network element is generally used to configure the clock time synchronization source point by point. Since the number of clock transmission link network elements is limited, it is necessary to carefully plan the clock time network, and special atten...
