Explanation

Role of the Southbound Interface Primary Function: The southbound interface enables direct communication between a program running on the controller (such as an SDN controller) and a program or software agent on networking devices like switches and routers. Protocols Used: Common protocols for southbound interfaces include OpenFlow, NETCONF, and REST APIs. These allow the controller to: - Push forwarding rules - Collect data and statistics - Manage device configurations dynamically
