Node to Node Performance Evaluation through RYU SDN Controller

Over the last few years, networks became more innovative for constructing and managing with the support of Software Defined Networking (SDN). The inflexibility of typical network architecture gives a great challenge to researchers. SDN is replacing current inflexible and complex networks with an innovative way where the control plane is decoupled from the data plane and fixing some limitations, including manual configuration, debugging, security, scalability, and mobility. Therefore, SDN controllers (e.g., NOX, POX, ONOS, OpenDaylight, Floodlight, Beacon, RYU, etc.) have emerged as a brain to manage such networks. SDN controller's performance study provides an excellent impact on enhancing the flexibilities and capabilities of an underlying SDN infrastructure network. This paper contextualizes the performance test analysis on the SDN controller is carried out through criterion (e.g., Throughput, Round-Trip Time, etc.). To implement an SDN architecture, this work uses a Mininet emulator containing a controller RYU with switching hub component, one OpenFlow switch, and three nodes. The aim is to evaluate the performance parameters such as Bandwidth, Throughput, Round-Trip Time, Jitter, and Packet loss between nodes using the RYU controller.
