Abstract
A time source signal determination method and apparatus, a network device, and a storage medium are provided. The method is performed by the network device, and includes: obtaining respective data sets of at least two time source signal, wherein the data sets include at least one type of information among following types of information corresponding to the time source signals: a grandmaster clock identifier, a grandmaster clock quality parameter, and path time accuracy; comparing the at least one type of information in the data sets of the at least two time source signals, and determining a better time source signal based on a result of the comparison.
