Abstract

Methods, systems, and computer readable media for mitigating traffic storms are provided herein. In some aspects, a system for mitigating traffic storms includes a traffic storm detector configured to detect an indication of a traffic storm. The system may also include a software defined network (SDN) controller configured to generate and send SDN commands to a controllable network entity for mitigating the traffic storm. In some aspects, a method for mitigating traffic storms includes detecting an indication of a traffic storm, wherein the traffic storm includes a burst of message traffic in a network. The method further includes sending one or more SDN commands to a controllable and/or controlled network entity to mitigate the traffic storm.

Claims

1. A method for mitigating traffic storms, the method comprising:

detecting an indication of a traffic storm, wherein the traffic storm includes a burst of message traffic in a network; and

in response to detection of the indication of the traffic storm, sending one or more software defined network (SDN) commands to a controlled network entity to mitigate the traffic storm.

2. The method of claim 1, wherein detecting an indication of a traffic storm occurs at an SDN controller.

3. The method of claim 2, wherein the SDN controller comprises an OpenFlow controller and wherein the controlled network entity comprises an OpenFlow compatible switch.

4. The method of claim 2, wherein the SDN controller includes a stand-alone node.

5. The method of claim 2, wherein the SDN controller is integrated within a policy and charging rules function (PCRF).

6. The method of claim 1, wherein the SDN commands instruct the controlled network entity to allocate additional resources to mitigate the traffic storm.

7. The method of claim 1, wherein the SDN commands instruct the controlled network entity to route traffic to alternate networks or service nodes.

8. The method of claim 7, wherein the alternate networks include one or more dynamically created networks.

9. The method of claim 7, wherein the alternate networks include one or more pre-existing networks offered by an alternate carrier.

10. The method of claim 1, wherein the SDN commands partition traffic based upon a class of traffic, an emergency indicator, a destination, an address, an IP prefix, an IP address, one or more QoS rules, or one or more policy rules.

11. The method of claim 1, wherein the traffic storm includes registration traffic following a service outage.

12. A system for mitigating traffic storms, the system comprising:

a traffic storm detector for detecting an indication of a traffic storm, wherein the traffic storm comprises a burst of message traffic in a network; and

a software defined network (SDN) controller configured to generate and send SDN commands to a controlled network entity to mitigate the traffic storm.

13. The system of claim 12, wherein the controlled network entity comprises an OpenFlow compatible switch.

14. The system of claim 12, wherein the SDN controller includes a stand-alone node.

15. The system of claim 12, wherein the SDN controller is integrated with a policy and charging rules function (PCRF).

16. The system of claim 12 wherein the SDN commands instruct the controlled network entity to allocate additional resources to mitigate the traffic storm.

17. The system of claim 12, wherein the SDN commands instruct the controlled network entity to route traffic to alternate networks or service nodes.

18. The system of claim 17, wherein the alternate networks include one or more dynamically created networks.

19. The system of claim 17, wherein the alternate networks include one or more pre-existing networks offered by an alternate carrier.

20. The system of claim 12, wherein the SDN commands partition traffic according to a class of traffic, an emergency indicator, a destination, an address, an IP prefix, an IP address, one or more QoS rules, or one or more policy rules.

21. The system of claim 12, wherein the traffic storm includes registration traffic following a service outage.

22. A non-transitory computer readable medium having stored thereon computer executable instructions embodied in a computer readable medium and when executed by a processor of a computer performs steps comprising:

detecting an indication of a traffic storm, wherein the traffic storm includes a burst of message traffic in a network; and

in response to detection of the indication of the traffic storm, sending one or more software defined network (SDN) commands to a controlled network entity to mitigate the traffic storm.
