NFV decouples the network functions from hardware so they can run in software
This reduces the need to purchase hardware and enables pay-as-you-grow models to eliminate over provisioning. Network Functions Virtualization (NFV) offers a new way to design, deploy and manage networking services. NFV decouples network functions, such as network address translation (NAT), firewalling, intrusion detection, domain name service (DNS), and caching, from proprietary hardware appliances, so they can run in software. It’s designed to consolidate and deliver the networking components needed to support a fully virtualized infrastructure – including virtual servers, storage and even other networks. It utilizes standard IT virtualization technologies that run on high-volume service, switch and storage hardware to virtualize network functions.
- Reduce CapEx: reducing the need to purchase purpose-built hardware and supporting pay-as-you-grow models to eliminate wasteful over provisioning.
- Reduce OpEX: reducing space, power and cooling requirements of equipment and simplifying the roll out and management of network services.
- Accelerate Time-to-Market: reducing the time to deploy new networking services to support changing business requirements, seize new market opportunities and improve return on investment of new services. Also lowers the risks associated with rolling out new services, allowing providers to easily trial and evolve services to determine what best meets the needs of customers.
- Deliver Agility and Flexibility: quickly scale up or down services to address changing demands; support innovation by enabling services to be delivered via software on any industry-standard server hardware.
