Methods, systems, and computer readable media for mitigating traffic storms
First Claim
1. A method for mitigating traffic storms, the method comprising:
- providing a traffic storm detector at a controlled network entity associated with a first network, wherein the controlled network entity is configured to route message traffic to a first node in the first network;
detecting, at the traffic storm detector, an indication of a traffic storm, wherein the traffic storm includes a burst of message traffic directed towards the controlled network entity;
communicating the indication of the traffic storm to a separate controller that is remotely located with respect to the traffic storm detector;
in response to receiving the indication of the traffic storm at the controller, sending, by the controller, one or more software defined network (SDN) commands to the controlled network entity to mitigate the traffic storm; and
in response to receiving the one or more SDN commands at the controlled network entity, routing some of the message traffic to the first node in the first network and dynamically re-routing at least some of the message traffic to a second node in a second network.

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.

12. A system for mitigating traffic storms, the system comprising:
-
a traffic storm detector disposed at a controlled network entity for detecting an indication of a traffic storm, wherein the traffic storm comprises a burst of message traffic directed towards the controlled network entity, and wherein the controlled network entity is configured to route message traffic to a first node in a first network; and a software defined network (SDN) controller configured to receive a communication from the traffic storm detector regarding the indication of the traffic storm, wherein the SDN controller is remotely located with respect to the traffic storm detector, and wherein the SDN controller is configured to generate and send SDN commands to the controlled network entity to mitigate the traffic storm; wherein, in response to receiving the one or more SDN commands at the controlled network entity, the controlled network entity is configured to route some of the message traffic to the first node in the first network and dynamically re-route at least some of the message traffic to a second node in a second network. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

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 via a traffic storm detector provided at a controlled network entity, wherein the controlled network entity is configured to route message traffic to a first node in a first network, and wherein the traffic storm includes a burst of message traffic in the first network directed towards the controlled network entity; communicating the indication of the traffic storm to a separate controller that is remotely located with respect to the traffic storm detector; in response to receiving the indication of the traffic storm at the controller, sending, by the controller, one or more software defined network (SDN) commands to the controlled network entity to mitigate the traffic storm; and in response to receiving the one or more SDN commands at the controlled network entity, routing some of the message traffic to the first node in the first network and dynamically re-routing at least some of the message traffic to a second node in a second network.
