A method for locating a clock fault includes that a network device locates a clock fault source based on whether first frequency offsets between a plurality of input clocks and a local clock exceed a frequency offset threshold, or based on whether second frequency offsets between the input clocks exceed a relative frequency offset threshold.

Method and network device for locating clock fault

A clock port attribute recovery method includes a network device setting a value of a port attribute of a clock port of the network device to a first value based on the clock port not receiving any one of three types of clock messages: N synchronization messages, follow-up messages, and delay response messages within a timeout interval, where the first value indicates that a message is lost on the clock port. Based on a case that a recovery condition is met, the network device sets the value of the port attribute of the clock port to a second value, where the second value indicates that a status of the clock port is that the message is not lost.

A method for synchronizing a network device includes: receiving, by the network device, a first SSM and a second SSM, where the first SSM carries a first SSM code for indicating a quality level of a first clock source and a first eSSM code for indicating the quality level of the first clock source, and the second SSM carries a second SSM code for indicating a quality level of a second clock source and a second eSSM code for indicating the quality level of the second clock source. When a value of the first SSM code is less than a value of the second SSM code, the network device calibrates a frequency of the network device based on a timing signal of the first clock source.

A time synchronization method includes, a boundary device of a third-party network side receives a synchronization packet carrying a time synchronization offset and is delivered by a boundary device of an upstream network side on the basis that boundary devices in an entire network are all boundary clock (BC) devices, where the time synchronization offset is a time offset between a time domain of the upstream network and a time domain of the third-party network, and the boundary device of the third-party network side transparently transmits the synchronization packet carrying the time synchronization offset to a boundary device of a downstream network side such that the boundary device of the downstream network side performs time synchronization with the boundary device of the upstream network side according to the time synchronization offset. Thus time synchronization among multiple time domains in a network.

Embodiments of the present disclosure disclose a method for transmitting a clock packet. The method includes: a first network element generates a first clock packet, where the first clock packet includes a first source identity and first clock information, and the first source identity is used to indicate a device that provides the first clock information. The first network element sends the first clock packet to a second network element forming a ring network with the first network element. The first network element receives a second clock packet sent by the second network element, where the second clock packet includes a second source identity and second clock information, and the second source identity is used to indicate a device that provides the second clock information. The first network element skips tracking the second clock information after determining that the second source identity is the same as the first source identity.
