Abstract: 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.
