Performance Evaluation Of Software Defined –netwoek (sdn) Controller

Résumé: Traditional networks have relied on a distributed control plane, where decision-making and forwarding functions are tightly coupled within individual networking devices. However, this approach poses challenges in terms of network management, scalability, and fault tolerance . From this context , the concept of Software-Defined Networking (SDN) networks emerged , which is that networking approach that separates the control and data planes to enable centralized management of network traffic and configurations. This allows network administrators to easily configure, manage and monitor network resources. One key protocol that enables dynamic routing decisions in SDN is OpenFlow. Hence , this project proposes to evaluate the performance and fault tolerance capabilities of SDN controllers using Mininet, HPE-VAN SDN Controller, ONOS, and Opendaylight. The study will emulate SDN environments to test and evaluate SDN networks without disrupting existing network infrastructure. The project will investigate the impact of various network parameters, including topology, traffic patterns, and controller placement, on SDN performance. The findings of this study will help network designers and operators identify optimal configurations that maximize performance and fault tolerance in SDN networks. Overall, this project will provide insights that can inform the deployment and management of SDN networks.
