Implementation and Comparison of Software-Defined Network Controllers in various Simulated Network Environments

Abstract

In today's ever-evolving networking landscape, Software Defined Networking (SDN) has emerged as a paradigm-shifting technology that promises greater flexibility, agility, and control over network infrastructures. However, how easy are the configuration, extensibility, and programmability of these SDN controllers, considering the practical implications for network administrators and developers? This study aims to explore the practical implementation and comparative evaluation of different SDN Controllers within diverse simulated network environments. Prominent controllers such as POX and Faucet are meticulously configured and deployed in simulated network environments created using GNS3, NS3, OPNET, OMNET + + and MININET platforms. Furthermore. the study employs a range of performance metrics like controller latency, network throughput, packet loss, CPU and memory utilization to assess the efficacy and efficiency of each SDN Controller.
