    Abstract: An embodiment of the present invention discloses a data sending and receiving method. A first FEC unit of a sending device sends, by using a first channel, a first data stream on which first FEC encoding has been performed; a second FEC unit of the sending device sends, by using a second channel, a second data stream on which second FEC encoding has been performed; and the sending device performs interleaving on the first data stream and the second data stream, to obtain an output data stream, and sends the output data stream to a receiving device and error correction capability of a receiving device could be improved. In addition, in the present invention, an operation of writing by row and reading by column does not need to be performed. Therefore, no delay is generated.

    Abstract: A method includes a network device receiving a plurality of fragments of an Ethernet frame, where the plurality of fragments include an initial fragment and a first fragment, and where the initial fragment includes a destination media access control (MAC) address field. In response to an error occurring in the Ethernet frame, the first fragment is changed to a second fragment, where the second fragment includes second type indication information (TII) and second to-be-transmitted data (TBTD), where the second TII indicates that a type of the second TBTD is a control character, where a value of first TBTD is different from a value of the second TBTD, and where the second TBTD indicates that an error occurs in the Ethernet frame. The network device sends the second fragment to a destination device.

    Abstract: This disclosure provides a method for sending and receiving a clock synchronization packet in FlexE. The method includes: generating, by a sending apparatus, indication information and a plurality of data blocks, where the plurality of data blocks are obtained by encoding a first clock synchronization packet, the indication information is used to indicate a first data block, and the first data block is a data block used for timestamp sampling in the plurality of data blocks; determining, by the sending apparatus, according to the indication information, a moment at which the first data block arrives at a medium dependent interface MDI of the sending apparatus, and generating a sending timestamp, where the sending timestamp is used to record a sending moment of the first clock synchronization packet; generating a second clock synchronization packet carrying the sending timestamp; and sending, by the sending apparatus, the second clock synchronization packet.
