Performance Evaluation of the Controller in Software-Defined Networking

Classical Internet architecture plays major obstacles in IPV6 deployment. There exits different reasons to extend classical approach to be more polished. Next generation of future Internet demands for routing not only within the same network domain but also outside the domain. Along with this, it offers many attributes such as network availability, end-to-end network connectivity, QoS management dynamically, and many more. The application area extends from small network size to big data center. To take in hand all these concerns, software-defined networking (SDN) has taken the major role in current situations. SDN separates the control plane and data plane to make the routing more versatile. We model the packet-in message processing of SDN controller as the queueing systems M/M/1.
