Explain the architecture of SDN and its application in IoT.
Answer
SDN separates the control plane from the data plane for dynamic network management.
Software-Defined Networking (SDN) is an architecture that abstracts different, distinguishable layers of a network to make networks agile and flexible. The core concept is the separation of the control plane (which decides where traffic is sent) from the data plane (which forwards traffic to the selected destination).
In IoT, SDN helps manage the massive influx of data by centrally controlling network traffic routing, ensuring QoS for critical applications, and dynamically adjusting to network changes without manual intervention.
