Abstract: A method for selecting a clock source includes a first network device that obtains synchronization offset data between the first network device and a second network device through a first port in a clock synchronization failed state. The first network device determines, based on the synchronization offset data, whether to refer to, during clock source selection, clock information received by the first port.

Abstract: A method includes: a first network device obtains a synchronization mode indication and synchronization information, where the synchronization mode indication indicates a target network device to perform synchronization based on the synchronization information. The first network device sends the synchronization mode indication and the synchronization information through a network that supports FlexE. A second network device receives the synchronization mode indication and the synchronization information through a network that supports FlexE. The second network device performs synchronization based on the synchronization mode indication and the synchronization information.

Abstract: After a first network device traces a clock of a second network device, when the first network device cannot trace the clock of the second network device, the first network device modifies a parameter value corresponding to a synchronization source selection parameter of the first network device to a first parameter value, where the first parameter value is superior to a parameter value corresponding to a synchronization source selection parameter of the second network device.

Abstract: A method and an apparatus determines a network device receiving a first signal and at least one second signal, wherein the first signal carries data to be sent through a first flexible Ethernet interface. A first physical layer clock is determined based on the first signal. A second physical layer clock is determined based on the at least one second signal or the first physical layer clock and the at least one second signal. The first physical layer clock or the second physical layer clock is used as a sending clock of a non-flexible Ethernet interface. The network device includes the first flexible Ethernet interface and the non-flexible Ethernet interface.

Abstract: This application discloses a time synchronization fault processing method, apparatus, and system, and belongs to the communication field. The method includes: When time of a first translator in a first network is not synchronized with a clock source in the first network, the first translator stops communicating time information with at least one other translator in the first network than the first translator, where the time information is used for obtaining time synchronized with a clock source in a second network.
