Abstract

An example first device may include a processor to establish a plurality of links associating between the first network device and a second network device, the plurality of links corresponding to a plurality of virtual local area networks (VLANs) that a plurality of client devices associated with the first network device belong to; create a mapping between the plurality of links and the plurality of VLANs; and forward data received from a particular client device among the plurality of client devices in a particular VLAN of the plurality of VLANs to the second network device via a particular link corresponding to the particular VLAN based on the mapping.

Claims

1. A first network device comprising a processor to:

establish a plurality of links associating between the first network device and a second network device, the plurality of links corresponding to a plurality of virtual local area networks (VLANs) that a plurality of client devices associated with the first network device belong to;

create a mapping between the plurality of links and the plurality of VLANs; and

forward data received from a particular client device among the plurality of client devices in a particular VLAN of the plurality of VLANs to the second network device via a particular link corresponding to the particular VLAN based on the mapping.

2. The first network device of claim 1, wherein the processor is further to:

select the corresponding one of the plurality of links by looking up the mapping, in response to receiving the data from the client device in the particular VLAN.

3. The first network device of claim 1, wherein the processor is further to:

determine the VLAN that the client device corresponding to the data belongs to, by looking up the mapping, in response to receiving the data from the second network device via a particular link of the plurality of links.

4. The first network device of claim 1, wherein the processor is further to:

receive service set identifiers (SSIDs) corresponding to the plurality of VLANs from the second network device.

5. The first network device of claim 1, wherein the processor is further to:

establish a link associating between the first network device and the second network device and corresponding to the VLAN that the first network device belongs to.

6. The first network device of claim 5, wherein the processor is further to:

receive an IP address assigned for the first network device from the second network device via the link corresponding to the VLAN that the first network device belongs to.

7. The first network device of claim 1, wherein the network device comprises an access point (AP), and the neighbor network device comprises another AP.

8. A method comprising:

establishing, by a processor of a first network device, a plurality of links associating between the first network device and a second network device, the plurality of links corresponding to a plurality of virtual local area networks (VLANs) that a plurality of client devices associated with the first network device belong to;

creating, by the processor, a mapping between the plurality of links and the plurality of VLANs;

forwarding, by the processor, data received from a particular client device among the plurality of client devices in a particular VLAN of the plurality of VLANs to the second network device via a particular link corresponding to the particular VLAN based on the mapping.

9. The method of claim 8, further comprising:

selecting, by the processor, the corresponding one of the plurality of links by looking up the mapping, in response to receiving the data from the client device in the particular VLAN.

10. The method of claim 8, further comprising:

determining, by the processor, the VLAN that the client device corresponding to the data belongs to, by looking up the mapping, in response to receiving the data from the second network device via a particular link of the plurality of links.

11. The method of claim 8, further comprising:

receiving, by the processor, service set identifiers (SSIDs) corresponding to the plurality of VLANs from the second network device.

12. The method of claim 8, further comprising:

establishing, by the processor, a link associating between the first network device and the second network device and corresponding to the VLAN that the first network device belongs to.

13. The method of claim 8, further comprising:

receiving, by the processor, an IP address assigned for the first network device from the second network device via the link corresponding to the VLAN that the first network device belongs to.

14. A non-transitory computer readable storage medium storing instructions that, when executed by a processor of a first network device, causes the processor to:

establish a plurality of links associating between the first network device and a second network device, the plurality of links corresponding to a plurality of virtual local area networks (VLANs) that a plurality of client devices associated with the first network device belong to;

create a mapping between the plurality of links and the plurality of VLANs; and

forward data received from a particular client device among the plurality of client devices in a particular VLAN of the plurality of VLANs to the second network device via a particular link corresponding to the particular VLAN based on the mapping.

15. The non-transitory computer readable storage medium of claim 14, wherein instructions that, when executed by the processor, further cause the processor to:

receive service set identifiers (SSIDs) corresponding to the plurality of VLANs from the second network device.
