In SDN, what is the role of Network Function Virtualization (NFV)?
- NFV virtualizes network functions, such as firewalls and load balancers, allowing them to run as software instances on commodity hardware.
- NFV is responsible for physical connectivity in SDN, ensuring that network devices are properly connected.
- NFV is an obsolete concept in SDN, and its role has been replaced by more advanced technologies.
- NFV is only applicable in traditional, non-virtualized networking environments.
