The objective of NFV is to decouple functions, such as firewall management, intrusion detection, network address translation, or name service resolution, away from specific hardware implementation into software solutions. NFV's focus is to optimize distinct network services.
With the focus on network service management and not hardware deployment, NFV readily supports capacity management since there is a more thorough utilization of resources.
As service providers struggled to keep up with the quick deployment needs and faster growth models, the slowness of hardware-based solutions was exposed.
A number of these service providers came together and founded the European Telecommunications Standards Institute (ETSI) and worked to formalize NFV standards.
The following benefits are sought for using NFV:
- Support transition from capital expenditure to operational expenditure (CapEx to OpEx).
- Reduce wait time in time-tomarket ventures.
- Increase service consumption agility.
