Network functions virtualization (NFV)
is an initiative to virtualize
the network services that are now being carried out by proprietary,
dedicated hardware. If successful, NFV will decrease the amount of proprietary
hardware that's needed to launch and operate network services.
Making Networks
Virtual: The Latest on SDN Technologies
An exploration of Software-Defined
Networking (SDN) technologies, network virtualization fundamentals, and the
latest developments for both – helping IT pros adapt them to a modern hybrid
network architecture.

The goal of NFV is to decouple
network functions from dedicated hardware devices and allow network services
that are now being carried out by routers,
firewalls,
load
balancers and other dedicated hardware devices to be hosted on
virtual machines (VMs).
Once the network functions are under the control of a hypervisor,
the services that once require dedicated hardware can be performed on standard
x86 servers.
This capability is important because it
means that network administrators will no longer need to purchase dedicated
hardware devices in order to build a service chain. Because server capacity
will be able to be added through software, there will be no need for network
administrators to overprovision their data centers which will reduce both
capital expenses (CAPex)
and operating expenses (OPex).
If an application running on a VM required more bandwidth, for example, the
administrator could move the VM to another physical server or provision another
virtual machine on the original server to take part of the load. Having this
flexibility will allow an IT department to respond in a more agile manner to
changing business goals and network service demands.
The NFV
concept, which was presented by a group of network
service providers at the Software Defined Network (SDN)
and OpenFlow
World Congress in October 2012, is being developed by the ETSI Industry
Specification Group (ISG) for Network Functions Virtualization.
