Performance Analysis of POX and RYU Based on Dijkstra’s Algorithm for Software Defined Networking

Conventional network architectures are not appropriate for the needs of current businesses, carriers, and end-users. Consequently, new evolving network architecture, Software Defined Network can be used to solve a problem as it is more adaptive, dynamic, manageable, and programmable. The SDN architecture control and data planes are isolated, network information and the state are legalized, and the essential network infrastructure is excluded from the applications. However, a network may achieve a point where the computer or network resources restrict the data flow that is controlled according to the bandwidth. In this paper, the custom network topology is created. To observe the performance of Dijkstra's shortest route algorithm in the SDN open-source controllers: RYU and POX to find out the shortest route between source and the destination nodes. The controller's performance is calculated based on the quality-of-service measures, containing throughput and packet delivery ratio in custom network topology under the various workload. The Mininet emulator tool is used to construct the custom network topology. The results are obtained by simulating different QoS requirements in customized topology in Mininet.
