Abstract

Techniques for extending local cellular WAN capabilities to a connected device are disclosed. In some embodiments, a system, a process, and/or a computer program product for extending local cellular wide area network (WAN) capabilities to a connected device includes selecting a first network communication device associated with a software-defined wide area network (SD-WAN) for policy enforcement, wherein the policy enforcement includes SD-WAN path selection; monitoring cellular network status information associated with a second network communication device of the SD-WAN; and synchronizing the cellular network status information associated with the second network communication device of the SD-WAN with the first network communication device associated with the SD-WAN, wherein the first network communication device associated with the SD-WAN uses the network status information for the policy enforcement.

Claims (32)

1 . A system, comprising:

a processor configured to:

select a first network communication device associated with an SD-WAN for policy enforcement, wherein the policy enforcement includes SD-WAN path selection;

monitor cellular network status information associated with a second network communication device of the SD-WAN; and

synchronize the cellular network status information associated with the second network communication device of the SD-WAN with the first network communication device associated with the SD-WAN, wherein the first network communication device associated with the SD-WAN uses the network status information for the policy enforcement, wherein the first network communication device associated with the SD-WAN includes a dual SIM and single radio for cellular network access, and wherein the second network communication device associated with the SD-WAN includes a non-cellular network communication access, and wherein the second network communication device can utilize cellular access via the first network communication device, and wherein the SD-WAN path selection is based at least in part on application/network reachability; and

a memory coupled to the processor and configured to provide the processor with instructions.

2 . The system of claim 1 , wherein the policy enforcement includes routing of traffic associated with the first network communication device associated with the SD-WAN.

3 . The system of claim 1 , wherein the policy enforcement includes traffic steering of traffic associated with the first network communication device associated with the SD-WAN.

4 . The system of claim 1 , wherein the policy enforcement includes monitoring traffic associated with the first network communication device associated with the SD-WAN and the second network communication device associated with the SD-WAN for a cloud security service.

5 . The system of claim 1 , wherein the first network communication device associated with the SD-WAN and the second network communication device associated with the SD-WAN are a high availability (HA) pair.

6 . The system of claim 1 , wherein the first network communication device associated with the SD-WAN and the second network communication device associated with the SD-WAN are a high availability (HA) pair for the SD-WAN, wherein the second network communication device is in a standby mode for the first network communication device.

7 . The system of claim 1 , wherein the first network communication device associated with the SD-WAN and the second network communication device associated with the SD-WAN are a high availability (HA) pair for the SD-WAN, wherein the second network communication device is in a standby mode for the first network communication device, wherein the first network communication device includes a first cellular radio, and wherein the second network communication device includes a second cellular radio.

8 . The system of claim 1 , wherein the SD-WAN path selection is based at least in part on application/network reachability.

9 . The system of claim 1 , wherein the processor is further configured to:

synchronize network status information associated with the first network communication device associated with the SD-WAN with the second network communication device associated with the SD-WAN.

10 . A method, comprising:

selecting a first network communication device associated with an SD-WAN for policy enforcement, wherein the policy enforcement includes SD-WAN path selection;

monitoring cellular network status information associated with a second network communication device of the SD-WAN; and

synchronizing the cellular network status information associated with the second network communication device of the SD-WAN with the first network communication device associated with the SD-WAN, wherein the first network communication device associated with the SD-WAN uses the network status information for the policy enforcement, wherein the first network communication device associated with the SD-WAN includes a dual SIM and single radio for cellular network access, and wherein the second network communication device associated with the SD-WAN includes a non-cellular network communication access, and wherein the second network communication device can utilize cellular access via the first network communication device, and wherein the SD-WAN path selection is based at least in part on application/network reachability.

11 . The method of claim 10 , wherein the policy enforcement includes routing of traffic associated with the first network communication device associated with the SD-WAN.

12 . The method of claim 10 , wherein the policy enforcement includes traffic steering of traffic associated with the first network communication device associated with the SD-WAN.

13 . The method of claim 10 , wherein the first network communication device associated with the SD-WAN and the second network communication device associated with the SD-WAN are a high availability (HA) pair.

14 . The method of claim 10 , wherein the first network communication device associated with the SD-WAN and the second network communication device associated with the SD-WAN are a high availability (HA) pair for the SD-WAN, wherein the second network communication device is in a standby mode for the first network communication device.

15 . A computer program product embodied in a non-transitory computer readable medium and comprising computer instructions for:

selecting a first network communication device associated with an SD-WAN for policy enforcement, wherein the policy enforcement includes SD-WAN path selection;

monitoring cellular network status information associated with a second network communication device of the SD-WAN; and

16 . The computer program product of claim 15 , wherein the policy enforcement includes routing of traffic associated with the first network communication device associated with the SD-WAN.

17 . The computer program product of claim 15 , wherein the policy enforcement includes traffic steering of traffic associated with the first network communication device associated with the SD-WAN.

18 . The computer program product of claim 15 , wherein the first network communication device associated with the SD-WAN and the second network communication device associated with the SD-WAN are a high availability (HA) pair.

19 . The computer program product of claim 15 , wherein the first network communication device associated with the SD-WAN and the second network communication device associated with the SD-WAN are a high availability (HA) pair for the SD-WAN, wherein the second network communication device is in a standby mode for the first network communication device.

20 . The method of claim 10 , wherein the SD-WAN path selection is based at least in part on application/network reachability.
