Abstract: A sending method, a receiving method, an apparatus, a system, a device, and a storage medium. The receiving method includes: obtaining an encoded data block, where the encoded data block includes a plurality of data blocks, a plurality of first parity bits, and an FEC parity bit, the plurality of first parity bits are in one-to-one correspondence with the plurality of data blocks, and the FEC parity bit corresponds to the plurality of data blocks; and then checking the corresponding data blocks based on the plurality of first parity bits and/or the FEC parity bit, to obtain a decoding result of the encoded data block.

Abstract: This application discloses a data transmission method. The method includes: performs bit multiplexing to obtain a plurality of third data streams based on a plurality of first data streams and a plurality of second data streams, where the first data stream and the second data stream belong to different virtual lane groups; and transmits the plurality of third data streams to a second module, to enable the second module to obtain a plurality of fourth data streams based on the plurality of third data streams, where any fourth data stream is obtained by performing bit multiplexing on any second quantity of third data streams in the plurality of third data streams. Bit multiplexing is performed on the obtained data streams, so that the method can improve a transmission rate of the data stream and reduce a frame loss ratio of a system.

Abstract: Embodiments of this application disclose a synchronization method and a device. First, a device marks, based on a preset period, a periodic code block in a data bitstream to be sent from a MAC layer to a PHY layer, then sends the data bitstream to a peer device through the PHY layer, records a sending time of each periodic code block as a first timestamp during sending, and returns the first timestamp to the MAC layer. To be specific, by marking a timestamp for the periodic code block received from the MAC layer, the device sets a PHY-layer-based time reference scale (namely, the first timestamp) at the PHY layer.
