Network Function Virtualization (NFV)

Definition

Network Function Virtualization (NFV) is a network architecture concept that uses virtualization technologies to manage network services through software rather than hardware. This approach allows for the decoupling of network functions from proprietary hardware, enabling more flexibility, scalability, and efficiency in deploying and managing network services, which is essential for the evolving demands of connected vehicles relying on advanced communication technologies like 5G.
