Software Defined Networks (SDN) has an emerging network architecture with a logically centralized control and a simple role of a forwarding plane. Its main distinguishing feature from tradition network is the separation of the data plane and the control plane. SDN controllers that are compact with multiple controllers called distributed controllers. The cluster of the controller provides availability and scalability, especially for a large-scale network operation such as data center. In this paper, we proposed a solution for a single point failure using clustering method and providing authentication-based access to the controller.
