Embodiments of this application disclose a synchronization method and a device. 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. The device 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. 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.

This application discloses example data sending methods and apparatuses, and an example FlexE switching system. In one example, when slice packets received include a SOP flag and an EOP flag of a same data packet, immediately data packet slices is restored in the slice packets to a FlexE data stream and the FlexE data stream is sent, or the data packet slices are restored in the slice packets to the FlexE data stream and the FlexE data stream is sent when a latency is greater than or equal to a first present duration. When the slice packets received include the SOP flag but do not include the EOP flag of a data packet, the data packet slices are restored in the slice packets and the FlexE data stream is sent when the latency reaches a second preset duration. The first preset duration is less than the second preset duration.
