Topology Discovery Tool for OpenFlow Controllers

Decoupling the control plane from the forwarding plane is suggested by Software Defined Networks (SDNs). The OpenFlow SDN control protocol can be used to deploy SDN for virtual switches communications in this new architecture, which provides centralized management and monitoring. The creation of SDN technology based on software programming necessitates tests and measuring equipment that can assess performance. However, the open-source performance tools for SDN architecture that are currently available only test the fundamental attributes, despite the fact that there are numerous SDN controllers that require evaluation with relation to topology discovery time. As a performance monitoring tool for SDN controllers, this study suggests the Topology Discovery Tool (TDT). This tool can measure how quickly various topology sizes converge. The northbound interface of Python programming was used to create this utility. The tool is used in the research to evaluate the performance of well-known SDN controllers in systems with various topology sizes and out-of-band control strategies, including an Open Network Operating System, OpenDaylight, and Floodlight.
