SECURING SOFTWARE DEFINED NETWORKS VIA FLOW DEFLECTION

摘要

A flow deflection capability is provided for deflecting data flows within a Software Defined Network (SDN) in order to provide security for the SDN. A flow forwarding rule is generated for a first network element of the SDN based on detection of a condition (e.g., TCAM utilization condition, CPU utilization condition, or the like) associated with the first network element. The flow forwarding rule is generated by a control element of the SDN or the first network element of the SDN. The flow forwarding rule is indicative that at least a portion of new flow requests received at the first network element are to be forwarded from the first network element to a second network element of the SDN. The flow forwarding rule may specify full flow deflection or selective flow deflection.

1. An apparatus, comprising:
a processor and a memory communicatively connected to the processor, the processor configured to:
receive, at a first network element of a software defined network from a second network element of the software defined network, a new flow request; andpropagate the new flow request from the first network element of toward a control element of the software defined network.
