Abstract: A communication method, a related apparatus, and a storage medium are provided. 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.

Abstract: A method of data processing is applied to a communications device including a first sublayer. A physical sublayer is added above a physical coding sublayer (PCS) of a physical layer, and the physical sublayer is connected to media independent interfaces (xMIIs) with different Ethernet rates. Data signals from different media access control clients (MAC) are interleaved using the physical sublayer. Then, a tx_cmd command is used to instruct the PCS to correspondingly encode an xMII signal. Finally, an encoded xMII signal is sent through a port. According to this method, an encoding function of the PCS may continue to be used, to decouple interleaving from encoding and perform the interleaving through an xMII interface. In this case, port channelization can be implemented for ports with multiple rates, and transmission of a high-priority service is ensured when there is an excessively large quantity of service flows in a transmission process.

Abstract: This application provides an example delay measurement method and an example network device. The method includes receiving, by a first network device, a first service flow. The method also includes determining, by the first network device, a first delay value based on a first measurement code block in the first service flow. The first delay value is a time difference between a first moment at which the first measurement code block is detected in the first network device and a second moment at which the first measurement code block is detected in the first network device.

Abstract: The present disclosure relates to flexible-Ethernet data processing methods and devices. One example method includes acquiring a to-be-switched first client service flow, where the first client service flow is a service flow suitable for transmission on a flexible Ethernet, performing first rate adaptation from a source clock domain to a target clock domain on the first client service flow to obtain a second client service flow that matches the target clock domain, and performing serial-to-parallel conversion on the second client service flow in the target clock domain to obtain a parallel client slot flow.
