Question
Discuss the role of Software Defined Networking (SDN) and Network Function Virtualization (NFV) in IoT. How do they enhance network management?
Answer
SDN centralizes network control, and NFV virtualizes network functions, making IoT networks scalable and flexible.
IoT networks are highly dynamic, with massive numbers of devices connecting and disconnecting. Traditional network architectures are too rigid to handle this efficiently. Software Defined Networking (SDN) addresses this by decoupling the network control plane from the forwarding (data) plane. A centralized SDN controller dynamically manages traffic routing based on application needs, ensuring Quality of Service (QoS).
Network Function Virtualization (NFV) abstracts network services (firewalls, IDS, load balancers) from dedicated hardware appliances to software instances running on standard servers. Together, they enhance network management by allowing administrators to programmatically reconfigure network topologies, rapidly deploy new security services to edge nodes, and scale infrastructure without physical hardware upgrades.
