NFV is designed to increase the flexibility and mobility of the network system, providing a more modular and scalable approach to network function management.
How is NFV Useful
Virtualization of network functions separates network functionality from the underlying hardware and instead runs them as software on computers or containers. This approach helps in the deployment, scaling and management of network functions, since they can move between physical servers or data centers as needed, without the use of specialized equipment.
NFV can be used to virtualize a wide range of network activities:
- security screens
- load balancers
- routers
- intrusion detection and elimination software.
NFV will also help providers quickly and easily implement new network services, reducing the time to market and allowing faster implementation of innovative services. Through consolidation, NFV reduces the complexity of the network, simplifies its management and increases overall efficiency.
NFV increases the reliability and fault tolerance of the network due to greater visibility and control over network functions, as well as the use of automated recovery mechanisms.
