A fantastic video on NFV

https://www.youtube.com/watch?v=vgFfbBCR9DsNetwork Functions Virtualization is converting existing network functions for an operator from stand alone purpose built appliances, to applications that run inside virtual machines in just a network. For operators, the method of virtualization is extremely valuable because it allows them never to only cut expenditures and operational expenses, but also allows them to be more agile in delivering services to their customers. Providing services to subscribers and enhancing subscriber experience are the main element goals of operators. Network Functions Virtualization gives operators the opportunity to attain those goals.

At Mobile World Congress this season Procera Networks is highlighting two accomplishments in the NFV space. The first accomplishment is Procera's power to take our PacketLogic technology and deploy it on a COTS server, running at line rate speeds of up to 150Gb/s. The second thing we are concentrating on this year for NFV, is our new relationship with Dell. We want to give our customers a choice in buying our technology. Customers may now either buy our existing platforms in the form of hardware, or if the customer is migrating to Network Functions Virtualization they could leverage Dell technology to get their platforms and run our PacketLogic software on it. This partnership is part of a strategy for Procera to make NFV real for our customers and to permit them to make real choices in how they deliver our packet technology of their infrastructure. There are three fundamental benefits that operators get from Network Functions Virtualization. The very first is capital expenditure reduction. By to be able to take your network functions and transform them into applications running on COTS server technology, operators are able to drive down the expense of building out their network infrastructure.

The second benefit for operators is a reduction in operations expense. A decrease in operations expense comes in the shape of being able to automate the provisioning and management lifecycle of your services letting you drop the operational overhead and burden of managing those services themselves. Finally the primary benefit is service agility. Quite simply, if you look at the traditional methodology for operators, it could take 9+ months in order for them to roll out a service. With Network Functions Virtualization they are able to trial services rapidly, construct them, and modify those services on the fly, leveraging automation technology.
