Abstract: A packet processing method is disclosed. According to the method, a first network device receives a first packet sent by a second network device, where the first packet includes a first group identifier corresponding to a VPN on the second network device, a first source device corresponding to the first packet belongs to the VPN, and the first source device is connected to the second network device. The first network device obtains a second group identifier based on a destination address of the first packet, where the second group identifier corresponds to the VPN on a third network device, a first destination device corresponding to the destination address of the first packet belongs to the VPN, and the first destination device is connected to the third network device. The first network device processes the first packet based on the first group identifier and the second group identifier.

Abstract: 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.

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.
