Architectural paradigm separating control and forwarding planes using centralized controllers and programmable interfaces.
Software-Defined Networking (SDN) separates network control from forwarding by using centralized controllers and programmable interfaces. It enables dynamic control, automation, and improved visibility across large networks. SDN reduces hardware dependency and supports centralized policy and traffic management for data centers and cloud infrastructures.
