A Useful and Effective Method for Selecting a Smart Controller for SDN Network Design and Implement

Software Defined Networking (SDN) is a modern network architectural model that manages network traffic using software. SDN is a networking scenario that modifies the conventional network design by combining all control features into a single place and making all choices centrally. Controllers are the "brains" of SDN architecture since they are responsible for making control decisions and routing packets at the same time. The capacity for centralized decision-making on routing improves the performance of the network. SDN's growing functionality and uses have led to the development of many controller systems. Every SDN controller idea or design must prioritize the control plane since it is the most crucial part of the SDN architecture. Studies have been done to examine, analyze, and evaluate the relative advantages of the many controllers that have been created in recent years. In this paper, finding the perfect controller based on derived needs (for example, the controller must have a "Java" or "Python" interface), a matching process compares controller features with requirements.
