Performance Evaluation of QoS metrics in Software Defined Networking using Ryu Controller

Abstract

Abstract With assistance from Software Defined Networking (SDN), networks have become more creative to build and maintain over the last few years. The inflexibility of modern network architecture is presenting researchers with a tough achievement. SDN replaces existing inescapable and complicated networks with a creative way of separating the control plane from the data plane and fixing those constraints, namely configurations done manually, monitoring, protection, usability, and functionality. SDN controllers (e.g., POX, RYU, ONOS, OpenDaylight, Floodlight, etc.) have therefore developed as a core for the management of these networks. The performance evaluation of the SDN controller has an outstanding effect on improving the flexibilities and abilities of a network topology of SDN infrastructures. This research summarizes the SDN controller performance tests using criteria (e.g., Bandwidth, Round-Trip Time). This study employs a Mininet emulator to enforce an SDN architecture that comprises an RYU controller with a switching part, one OpenFlow switch, and multiple nodes. The goal is to determine performance QoS (Quality of Service) including Bandwidth, Throughput using the iperf test.
