Software-defined network (SDN) is based on separating data plane from control plane and decision-making processes to centralize network control. The OpenFlow (OF) protocol is the most common and widely used in software-defined network for communicating and controlling switches. With this protocol, the switch learns the routing information from the controller and then passes data packets based on this information. One of the most important components of the SDN is the controller, which is the smartest component of the network. Many controllers have been developed since the advent of SDN. One of the most important and famous controllers is Ryu. Due to the importance of the Ryu controller in SDN, in this article, the performance of the Ryu controller in terms of latency and throughput are evaluated. Cbench is used for measuring throughput and latency of this controller
