摘要： This application provides a clock synchronization packet exchanging method and an apparatus. The clock synchronization packet exchanging method includes: sending, by a first device in a FlexE group, a first FlexE instance at a first PHY, where the first FlexE instance includes a clock synchronization packet, and a second FlexE instance sent by the first device in the FlexE group at a second PHY also includes a clock synchronization packet. In the technical solution provided in this application, the clock synchronization packets are carried in a plurality of flexible Ethernet (FlexE) instances transmitted between a transmit end and a receive end in the FlexE group, so that reliability of clock synchronization between the transmit end and the receive end in the FlexE group can be improved.

摘要： A communication method, a related apparatus, and a storage medium are provided, to resolve transparent transmission of clock frequency information of a service. In this application, a first communication apparatus receives a first service data stream, generates a first code block stream based on the first service data stream, and sends the first code block stream. The first code block stream includes first clock frequency information, and the first clock frequency information indicates transmission duration of k first data frames of the first service data stream, and/or a moment at which the k first data frames of the first service data stream are received. In this way, a second communication apparatus may send the k first data frames based on the first clock frequency information, so that a clock frequency of the k first data frames sent by the second communication apparatus are basically consistent with a clock frequency of the k first data frames received by the first communication apparatus. This can resolve transparent transmission of clock frequency information of a service.

摘要： 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. This application avoids obtaining incorrect time.

摘要： This application discloses a synchronization method, apparatus, and device, and a storage medium. The method includes: obtaining a first timestamp difference of a packet on a target link, where the first timestamp difference is a difference between a sending timestamp and a receiving timestamp of the packet at a first moment; performing packet selection based on the first timestamp difference to obtain a second timestamp difference; obtaining a delay prediction value of the target link at the first moment, compensating for the second timestamp difference based on the delay prediction value to obtain a compensated timestamp difference; and performing time and/or clock synchronization based on the compensated timestamp difference. The second timestamp difference is compensated for based on the delay prediction value, that is, PDV noise introduced to the target link is compensated for. In this way, the PDV noise is reduced, and the compensated timestamp difference more directly reflects frequency offset and phase offset information of a crystal oscillator relative to a frequency reference source, thereby improving synchronization precision and improving synchronization performance.
