Abstract
A novel technique is shown for throttling control traffic in a Software Defined Network (SDN) between a controller and network switches when the controller and/or one or more control channels are congested. In this technique, the controller's processing power and the limited control channel bandwidth are more efficiently managed by drastically cutting down the control traffic during times of congestion.
