Abstract: This application discloses a data sending method and apparatus, and a FlexE switching system. When slice packets received by a sending module include a SOP flag and a EOP flag of a same data packet, it indicates that the sending module receives a complete data packet, and immediately sends data packet slices, or sends the data packet slices after a latency of first preset duration. In this way, a stream inside the data packet is not interrupted, a data sending latency is reduced, and transmission efficiency is improved. When the slice packets received by the sending module include a SOP flag of a data packet but do not include a EOP flag of the data packet, it indicates that the sending module has not received a complete data packet, and then sends data packet slices after a latency of second preset duration longer than the first preset duration.
