Abstract: The present disclosure discloses a data transmission method, apparatus, device, and system, and a computer-readable storage medium. The data transmission method includes: A first chip obtains first data produced through coding data using a first FEC code type; determines a second FEC code type based on a reference clock frequency of the first chip and an output rate corresponding to the first FEC code type; codes the first data based on the second FEC code type to produce second data; and transmits the second data. A third chip receives the second data, and decodes the second data based on the second FEC code type, to produce decoded data.

Abstract: A forwarding table generation method is provided. The method includes: determining, by a forwarding device, a first timeslot set, where the first timeslot set includes multiple timeslots during which the forwarding device sends, to a first device by using a first flexible Ethernet group, multiple encoded data blocks generated by a physical coding sublayer; determining, by the forwarding device, a second timeslot set, where the second timeslot set includes multiple timeslots during which the forwarding device receives, by using a second FlexE group, the multiple encoded data blocks sent by a second device; and generating, by the forwarding device, a forwarding table, where the forwarding table includes a mapping relationship between the second FlexE group and the multiple timeslots included in the second timeslot set, and between the first FlexE group and the multiple timeslots included in the first timeslot set.
