Data sending method and forwarding device

A forwarding device, comprising:

• a computer-readable storage medium storing a program comprising instructions;
• and
• a processor coupled to the computer-readable storage medium, the instructions causing the processor to be configured to:
• receive, from a sending device, using a first flexible Ethernet (FlexE) group and in a plurality of timeslots comprised in a first timeslot set, a plurality of first encoded data blocks from a physical coding sublayer (PCS), wherein the first encoded data blocks are in a one-to-one correspondence with the timeslots in the first timeslot set, wherein the first FlexE group comprises at least one send physical layers (PHYs) and at least one receive PHYs, wherein the at least one send PHYs is bonded to the at least one receive PHYs in the first FlexE group, wherein the forwarding device comprises the at least one receive PHYs in the first FlexE group, and wherein the forwarding device is a next-hop device of the sending device;
• determine, based on a mapping relationship between the first FlexE group and timeslots comprised in the first timeslot set, a second FlexE group and a plurality of timeslots comprised in a second timeslot set, according to the timeslots comprised in the first timeslot set and the first FlexE group, wherein the second FlexE group and the plurality of timeslots are comprised in a second timeslot set;
• and
• send, to a receiving device, the first encoded data blocks using the second FlexE group and in the timeslots comprised in the second timeslot set, wherein the second FlexE group comprises at least one send PHYs and at least one receive PHYs, wherein the at least one send PHYs is bonded to the at least one receive PHYs in the second FlexE group, wherein the forwarding device comprises the at least one send PHYs in the second FlexE group, and wherein the receiving device is a next-hop device of the forwarding device.

A non-transitory computer-readable medium that stores therein a program causing a computer to:

• receive, from a sending device, using a first flexible Ethernet (FlexE) group and in a plurality of timeslots comprised in a first timeslot set, a plurality of first encoded data blocks from a physical coding sublayer (PCS), wherein the first encoded data blocks are in a one-to-one correspondence with the timeslots in the first timeslot set, wherein the first FlexE group comprises at least one send physical layers (PHYs) and at least one receive PHYs, wherein the at least one send PHYs is bonded to the at least one receive PHYs in the first FlexE group, wherein a forwarding device comprises the at least one receive PHYs in the first FlexE group, and wherein the forwarding device is a next-hop device of the sending device;
• determine, based on a mapping relationship between the first FlexE group and timeslots comprised in the first timeslot set, a second FlexE group and a plurality of timeslots comprised in a second timeslot set, according to the timeslots comprised in the first timeslot set and the first FlexE group, wherein the second FlexE group and the plurality of timeslots are comprised in a second timeslot set;
• and
• send, to a receiving device, the first encoded data blocks using the second FlexE group and in the timeslots comprised in the second timeslot set, wherein the second FlexE group comprises at least one send PHYs and at least one receive PHYs, wherein the at least one send PHYs is bonded to the at least one receive PHYs in the second FlexE group, wherein the forwarding device comprises the at least one send PHYs in the second FlexE group, and wherein the receiving device is a next-hop device of the forwarding device.
