Abstract

Methods and systems associated with fabric tunnels may assist in traffic flow through a tunnel that aggregates a plurality of virtual local area networks across a core network.

Claims (37)

1. A network switch comprising:

a processor; and

a memory coupled with the processor, the memory comprising executable instructions that when executed by the processor cause the processor to effectuate operations comprising:

receiving first data from a layer two switch, wherein the first data is from a port on a first virtual local area network (VLAN);

receiving second data from the layer two switch, wherein the second data is from the port on a second VLAN;

relating the first data and the second data to a tunnel context of a virtual private network (VPN) tunnel;

normalizing the first data and the second data for transport over the VPN tunnel, wherein normalizing comprises mapping the received VLANs to another respective VLAN number, wherein the received VLANs comprise the first VLAN and the second VLAN; and

forwarding the first data and the second data through the VPN tunnel based on the tunnel context.

2. The network switch of claim 1 , wherein the VPN tunnel has integrated pseudowire-headend that is terminated on a layer three provider edge.

3. The network switch of claim 1 , wherein the VPN tunnel terminates on a virtual layer three provider edge.

4. The network switch of claim 1 , wherein the network switch is connected with a multi-protocol label switching network.

5. The network switch of claim 1 , wherein the VPN tunnel terminates on a layer two provider edge.

6. The network switch of claim 1 , wherein the VPN tunnel terminates on a layer two switch.

7. The network switch of claim 1 , wherein the VPN tunnel terminates on a router.

8. A computer readable storage medium comprising computer executable instructions that when executed by a computing device cause the computing device to effectuate operations comprising:

receiving first data from a layer two switch, wherein the first data is from a port on a first virtual local area network (VLAN);

receiving second data from the layer two switch, wherein the second data is from the port on a second VLAN;

relating the first data and the second data to a tunnel context of a virtual private network (VPN) tunnel;

normalizing the first data and the second data for transport over the VPN tunnel, wherein normalizing comprises mapping the received VLANs to another respective VLAN number, wherein the received VLANs comprise the first VLAN and the second VLAN; and

forwarding the first data and the second data through the VPN tunnel based on the tunnel context.

9. The computer readable storage medium of claim 8 , wherein the VPN tunnel has integrated pseudowire-headend that is terminated on a layer three provider edge.

10. The computer readable storage medium of claim 8 , wherein the VPN tunnel terminates on a virtual router.

11. The computer readable storage medium of claim 8 , wherein the switch is connected with a multi-protocol label switching network.

12. The computer readable storage medium of claim 8 , wherein the VPN tunnel terminates on a virtual broadband network gateway.

13. The computer readable storage medium of claim 8 , wherein the VPN tunnel terminates on a layer two switch.

14. The computer readable storage medium of claim 8 , wherein the VPN tunnel terminates on a router.

15. A method comprising:

receiving first data from a layer two switch, wherein the first data is from a port on a first virtual local area network (VLAN);

receiving second data from the layer two switch, wherein the second data is from the port on a second VLAN;

relating the first data and the second data to a tunnel context of a virtual private network (VPN) tunnel;

normalizing the first data and the second data for transport over the VPN tunnel, wherein normalizing comprises mapping the received VLANs to another respective VLAN number, wherein the received VLANs comprise the first VLAN and the second VLAN; and

forwarding the first data and the second data through the VPN tunnel based on the tunnel context.

16. The method of claim 15 , wherein the VPN tunnel has integrated pseudowire-headend that is terminated on a layer three provider edge.

17. The method of claim 15 , wherein the VPN tunnel terminates on a virtual layer three provider edge.

18. The method of claim 15 , wherein the switch is connected with a multi-protocol label switching network.

19. The method of claim 15 , wherein the VPN tunnel terminates on a layer two provider edge.

20. The method of claim 15 , wherein the VPN tunnel terminates on a router.
