Abstract

A data sending 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.

First claim

What is claimed is:

1. A data transmitting method, implemented by a forwarding apparatus, comprising:
receiving, from a sending device in a first timeslot occupied by a Flexible Ethernet (FlexE) client, a first encoded data block of the FlexE client using a first FlexE group, wherein the first FlexE group comprises at least one first send physical layers (PHYs) and at least one first receive PHYs, wherein the at least one first send PHYs is bonded to the at least one first receive PHYs in the first FlexE group, wherein the forwarding apparatus comprises the at least one first receive PHYs, and wherein the forwarding apparatus is a next-hop device of the sending device;
mapping the first encoded data block received in the first timeslot into a second timeslot occupied by the FlexE client in a second FlexE group; and
sending, to a receiving device in the second timeslot and without performing layer 2 processing and layer 3 processing on the FlexE client between receiving the first encoded data block and sending the first encoded data block, the first encoded data block using the second FlexE group,
wherein the second FlexE group comprises at least one second send PHYs and at least one second receive PHYs,
wherein the at least one second send PHYs is bonded to the at least one second receive PHYs in the second FlexE group,
wherein the forwarding apparatus comprises the at least one second send PHYs in the second FlexE group, and
wherein the receiving device is a next-hop device of the forwarding apparatus.

2. The data transmitting method of claim 1 , wherein before sending the first encoded data block, the data transmitting method further comprises determining the second FlexE group and the second timeslot based on a mapping relationship between the first timeslot and the second timeslot.

3. The data transmitting method of claim 2 , wherein the forwarding apparatus comprises a first mapping table comprising the mapping relationship between the first timeslot and the second timeslot.

4. The data transmitting method of claim 1 , further comprising:
receiving, using the first FlexE group, a plurality of second encoded data blocks;
generating an Ethernet frame based on the second encoded data blocks; and
performing the layer 2 processing on the Ethernet frame.

5. The data transmitting method of claim 1 , further comprising:
receiving, using the first FlexE group, a plurality of second encoded data blocks;
generating an Ethernet frame based on the second encoded data blocks; and
performing the layer 3 processing on the Ethernet frame.

6. A forwarding apparatus, comprising:
a non-transitory computer-readable storage medium configured to store instructions;
a communication interface;
a processor coupled to the non-transitory computer-readable storage medium and the communication interface and configured to execute the instructions to:
receive, from a sending device in a first timeslot occupied by a Flexible Ethernet (FlexE) client, a first encoded data block of the FlexE client using a first FlexE group, wherein the first FlexE group comprises at least one first send physical layers (PHYs) and at least one first receive PHYs, wherein the at least one first send PHYs is bonded to the at least one first receive PHYs in the first FlexE group, wherein the forwarding apparatus comprises the at least one first receive PHYs in the first FlexE group, and wherein the forwarding apparatus is a next-hop device of the sending device;
map the first encoded data block received in the first timeslot into a second timeslot occupied by the FlexE client in a second FlexE group; and
send, to a receiving device in the second timeslot and without performing layer 2 processing and layer 3 processing on the FlexE client between receiving the first encoded data block and sending the first encoded data block, the first encoded data block using the second FlexE group,
wherein the second FlexE group comprises at least one second send PHYs and at least one second receive PHYs,
wherein the at least one second send PHYs is bonded to the at least one second receive PHYs in the second FlexE group,
wherein the forwarding apparatus comprises the at least one second send PHYs in the second FlexE group, and
wherein the receiving device is a next-hop device of the forwarding apparatus.

7. The forwarding apparatus of claim 6 , wherein before sending the first encoded data block, the processor is further configured to execute the instructions to determine the second FlexE group and the second timeslot based on a mapping relationship between the first timeslot and the second timeslot.

8. The forwarding apparatus of claim 6 , wherein the forwarding apparatus is a router, a switch, or a chip.

9. The forwarding apparatus of claim 6 , wherein the processor is further configured to execute the instructions to:
receive, using the first FlexE group, a plurality of second encoded data blocks;
generate an Ethernet frame based on the second encoded data blocks; and
perform the layer 2 processing on the Ethernet frame.

10. The forwarding apparatus of claim 6 , wherein the processor is further configured to execute the instructions to:
receive, using the first FlexE group, a plurality of second encoded data blocks;
generate an Ethernet frame based on the second encoded data blocks; and
perform the layer 3 processing on the Ethernet frame.

11. A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable medium that, when executed by a processor, cause a forwarding apparatus to:
receive, from a sending device in a first timeslot occupied by a Flexible Ethernet (FlexE) client, a first encoded data block of the FlexE client using a first FlexE group, wherein the first FlexE group comprises at least one first send physical layers (PHYs) and at least one first receive PHYs, wherein the at least one first send PHYs is bonded to the at least one first receive PHYs in the first FlexE group, wherein the forwarding apparatus comprises the at least one first receive PHYs in the first FlexE group, and wherein the forwarding apparatus is a next-hop device of the sending device;
map the first encoded data block received in the first timeslot into a second timeslot occupied by the FlexE client in a second FlexE group; and
send, to a receiving device in the second timeslot and without performing layer 2 processing and layer 3 processing on the FlexE client between receiving the first encoded data block and sending the first encoded data block, the first encoded data block using the second FlexE group,
wherein the second FlexE group comprises at least one second send PHYs and at least one second receive PHYs,
wherein the at least one second send PHYs is bonded to the at least one second receive PHYs in the second FlexE group,
