Explanation
Software defined networking (SDN) is a network architecture that decouples the control plane from the data plane, allowing for more flexibility and programmability of network functions. The SDN controller is the architectural component that acts as the brain of the SDN network, communicating with both the SDN applications and the SDN data paths. The SDN controller is responsible for translating the network requirements from the SDN applications, such as security policies, routing rules, or load balancing, into instructions for the SDN data paths, such as switches, routers, or firewalls, to implement them. The SDN controller also monitors the network state and provides feedback to the SDN applications.
