Abstract: : The need for scalable and effective data center networks has grown as a result of the big data analytics, cloud computing, and internet of things (IoT) industries' explosive growth. Traditional network architectures often struggle to keep track with the dynamic and resourceintensive needs of modern data centers. By separating the control plane from data plane, software defines network (SDN) has become a viably way to overcome this obstacles and allow for more programmable and adaptable network administration. The scalability, flexibility and manageability issues I medium-scale data centers can be addressed by the new and promising concept known as Software Defined Networking (SDN). This study aims to evaluate the performance of SDN implementations within such environments. Through a comprehensive review of existing literature, coupled with empirical analysis, this study investigates the impact of SDN on key performance metrics including throughput, latency, scalability, and resource utilization. Various SDN architectures, protocols, and deployment strategies are examined to identify their efficacy in medium-scale data center settings. By establishing a planned topology, the results offer important insights into the advantages and disadvantages of SDN in terms of maximizing network performance and scalability in the context of medium-sized data centers. First, a thorough analysis of SDN controllers was conducted, and the superior ONOS controller was chosen. After that, LXC is used to create three ONOS controllers and Python to develop tree topologies in Mininet. It is then examined the latency and throughput of these three ONOS controllers. The throughput and latency results for three, five, and seven ONOS controllers have finally been given. It is then, examined, and assessed the throughput and latency, of these three ONOS controllers. Three, five, and seven ONOS controllers' throughput and latency results have been shown by the researcher. The three ONOS controllers have a latency of 252.12 to 298.01 responses/ms and a flow/s throughput of 218916.5 to 229388.9. The five ONOS controllers have a latency of 761.82 to 894.03 responses/ms and a flow/s throughput of 656749.5 to 688166.7. The throughput of the Seven ONOS controller ranges from 1970248.50 to 2064500.10 flows/s, while the latency ranges from 2264.08 to 2667.09 responses/ms.
