Abstract: A data sending method, where the method includes receiving, by a forwarding device using a first flexible Ethernet (FlexE) group and in multiple timeslots included in a first timeslot set, multiple first encoded data blocks from a physical coding sublayer (PCS), determining, by the forwarding device according to the timeslots included in the first timeslot set and the first FlexE group, a second FlexE group and multiple timeslots included in a second timeslot set, and sending, by the forwarding device, the first encoded data blocks using the second FlexE group and in the timeslots included in the second timeslot set. The forwarding device does not need to process the first encoded data blocks in a conventional layer 2 or layer 3 forwarding mode. Therefore, a processing delay can be reduced, and a transmission delay can be reduced.
