Abstract

In various embodiments, the data plane may be abstracted from a control plane in a wireless network such as WiMax, WiFi, LTE or the like. In some embodiments, a method comprises a receiving control data at a control server from a source device, generating routing instructions at the control server regarding routing network data based on the control data, providing the routing instructions to a routing device, configuring the routing device based on the routing instructions, receiving network data from the source device, and routing the network data from the source device to a target device using the configured routing device.

Claims

1. A method comprising:

receiving control data at a control server from a source device;

generating routing instructions at the control server regarding routing network data based on the control data;

providing the routing instructions to a routing device;

configuring the routing device based on the routing instructions;

receiving network data from the source device; and

routing the network data from the source device to a target device using the configured routing device.

2. The method of claim 1, wherein the control server is a WiMAX server.

3. The method of claim 1, wherein the control server is an LTE server.

4. The method of claim 1, wherein the control server is an access server network (ASN) server and wherein providing the routing instructions comprises providing the routing instructions from the ASN server over an R7 interface to the routing device.

5. The method of claim 1, wherein the routing instructions comprise instructions to forward matching incoming traffic arriving on a specific ingress interface to a specific egress interface.

6. The method of claim 5, wherein the ingress interface comprises a specific generic routing encapsulation (GRE) tunnel and the egress interface comprises an IP to IP tunnel.

7. The method of claim 1, wherein the routing instructions comprise instructions to drop matching incoming traffic arriving on a specific ingress interface.

8. The method of claim 1, wherein the routing instructions comprise instructions to duplicating outgoing traffic to two or more egress interfaces.

9. The method of claim 1, wherein the routing instructions comprise instructions to buffer packets at an egress interface according to hierarchical quality of service (QoS) policies.

10. The method of claim 1, further comprising matching network data using packet classification rules to determine a routing function.

11. A system, comprising:

a control server configured to receive control data from a source device, generate routing instructions regarding routing network data based on the control data, and provide the routing instructions to a routing device; and

a routing device configured based on the routing instructions to receive network data from the source device, and route the network data from the source device to a target device based on the routing instructions.

12. The routing device of claim 11, wherein the control server is a WiMAX server.

13. The routing device of claim 11, wherein the control server is an LTE server.

14. The routing device of claim 11, wherein the control server is an access server network (ASN) server and the routing device communicates with the ASN server over an R7 interface.

15. The routing device of claim 11, wherein the routing instructions comprise instructions to forward matching incoming traffic arriving on a specific ingress interface to a specific egress interface.

16. The routing device of claim 15, wherein an ingress interface comprises a specific generic routing encapsulation (GRE) tunnel and the egress interface comprises an IP to IP tunnel.

17. The routing device of claim 11, wherein the routing instructions comprise instructions to drop matching incoming traffic arriving on a specific ingress interface.

18. The routing device of claim 11, wherein the routing instructions comprise instructions to duplicating outgoing traffic to two or more egress interfaces.

19. The routing device of claim 11, wherein the routing instructions comprise instructions to buffer packets at an egress interface according to hierarchical quality of service (QoS) policies.

20. The routing device of claim 11, wherein the routing device is further configured to match network data using packet classification rules to determine a routing function.

21. Computer readable medium comprising instructions, the instructions executable by a processor to perform a method, the method comprising:

receiving control data at a control server from a source device;

generating routing instructions at the control server regarding routing network data based on the control data instructions;

providing the routing instructions to a routing device;

configuring the routing device based on the routing instructions;

receiving network data from the source device; and

routing the network data from the source device to a target device using the configured routing device.
