Cell site gateway

1. A method comprising:

receiving, by a cell site gateway located at a cell site of an access network:

one or more first packets, from a network gateway, via a first interface of the cell site gateway;

one or more second packets, from a cellular base station, via a second interface of the cell site gateway; and

control information, from a control server, via a third interface of the cell site gateway, wherein the control information is for a forwarding layer of the cell site gateway, the control information comprising a first flow entry comprising a first match field and a second flow entry comprising a second match field;

transmitting, to the cellular base station via the first interface, first packets based on the first packets matching the first match field; and

transmitting, to the network gateway via the second interface, second packets based on the second packets matching the second match field.

2. The method of claim 1 , wherein the forwarding layer is further configured to swap at least one label on a plurality of packets.

3. The method of claim 1 , wherein the cell site gateway comprises a path computation engine.

4. The method of claim 1 , wherein the cell site gateway is configured to exchange the control information employing resource reservation protocol-traffic engineering (RSVP-TE).

5. The method of claim 1 , wherein the cell site gateway is configured to exchange the control information employing multi-protocol label switching-transport profile (MPLS-TP).

6. The method of claim 1 , wherein the cell site gateway is configured to exchange the control information employing a label distribution mechanism.

7. The method of claim 1 , wherein the cell site gateway is configured to route functionality supporting a link state routing protocol.

8. A cell site gateway, located at a cell site of an access network, comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the cell site gateway to:

receive:

one or more first packets, from a network gateway, via a first interface of the cell site gateway;

one or more second packets, from a cellular base station, via a second interface of the cell site gateway; and

control information, from a control server, via a third interface of the cell site gateway, wherein the control information is for a forwarding layer of the cell site gateway, the control information comprising a first flow entry comprising a first match field and a second flow entry comprising a second match field;

transmit, to the cellular base station via the first interface, first packets based on the first packets matching the first match field; and

transmit, to the network gateway via the second interface, second packets based on the second packets matching the second match field.

9. The cell site gateway of claim 8 , wherein the forwarding layer is further configured to swap at least one label on a plurality of packets.

10. The cell site gateway of claim 8 , wherein the cell site gateway comprises a path computation engine.

11. The cell site gateway of claim 8 , wherein the cell site gateway is configured to exchange the control information employing resource reservation protocol-traffic engineering (RSVP-TE).

12. The cell site gateway of claim 8 , wherein the cell site gateway is configured to exchange the control information employing multi-protocol label switching-transport profile (MPLS-TP).

13. The cell site gateway of claim 8 , wherein the cell site gateway is configured to exchange the control information employing a label distribution mechanism.

14. The cell site gateway of claim 8 , wherein the cell site gateway is configured to route functionality supporting a link state routing protocol.

15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a cell site gateway, cause the cell site gateway to:

receive:

one or more first packets, from a network gateway, via a first interface of a cell site gateway;

one or more second packets, from a cellular base station, via a second interface of the cell site gateway; and

control information, from a control server, via a third interface of the cell site gateway, wherein the control information is for a forwarding layer of the cell site gateway, the control information comprising a first flow entry comprising a first match field and a second flow entry comprising a second match field;

transmit, to the cellular base station via the first interface, first packets based on the first packets matching the first match field; and

transmit, to the network gateway via the second interface, second packets based on the second packets matching the second match field.

16. The non-transitory computer-readable medium of claim 15 , wherein the forwarding layer is further configured to swap at least one label on a plurality of packets.

17. The non-transitory computer-readable medium of claim 15 , wherein the cell site gateway comprises of a path computation engine.

18. The non-transitory computer-readable medium of claim 15 , wherein the cell site gateway is configured to exchange the control information employing resource reservation protocol-traffic engineering (RSVP-TE).

19. The non-transitory computer-readable medium of claim 15 , wherein the cell site gateway is configured to exchange the control information employing multi-protocol label switching-transport profile (MPLS-TP).

20. The non-transitory computer-readable medium of claim 15 , wherein the cell site gateway is configured to exchange the control information employing a label distribution mechanism.
