Abstract: A block generation method and apparatus, and a block receiving method and apparatus are disclosed. The block generation method includes: generating a first block and a second block, where the first block includes a first block unit, the second block includes a second block unit, a first indicator is configured in the first block unit, and the first indicator is used to indicate whether the second block unit is a control code; and sending the first block and the second block. According to this method, an indicator is configured in a block unit in the first block to indicate whether an adjacent block is a control code, so that a boundary between a control code and a data code is determined, thereby avoiding extra indication information for an indication and reducing overheads of the indication information.

Abstract: This application provides a data transmission method and a device. The method includes: adding data of at least one first device to a slot in a slot group, where the slot group includes N slots, a first slot is any slot in the slot group, the first slot includes M subslots, sequence information of the M subslots is located in any one of the M subslots, and both M and N are positive integers; and sending the data of the at least one first device to a second device by using the slot group. Sequence information of subslots of a slot is placed in any subslot of the slot, instead of being placed in an overhead frame, and therefore a receive end can learn of information about a sequence relationship in a relatively short time, reducing a time interval.

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.

Abstract: Embodiments of this application provide a method. A receiving device determines that a first PHY needs to be added to a first FlexE group in a working state; performs deskew on the first PHY or each PHY in the first FlexE group based on a received data stream corresponding to the first PHY and a received data stream corresponding to each PHY in the first FlexE group, and restores a data stream corresponding to a client from a PHY in the first FlexE group; and if skew between the data stream corresponding to the first PHY and the data stream corresponding to each PHY in the first FlexE group after the deskew is performed is zero, restores a data stream corresponding to a client from a PHY in a second FlexE group. Flexibility of adjusting a PHY in a FlexE group in a working state is improved.
