network functions virtualization (NFV)
Network functions virtualization (NFV) is an initiative to virtualize network
functions previously carried out by proprietary, dedicated hardware.
The concept, which was presented by a group of network service
providers at the SDN and OpenFlow World Congress in October 2012, and is being developed by the
ETSI Industry Specification Group (ISG) for Network Functions Virtualization. If successful, NFV
would decrease the amount of proprietary hardware that’s needed to launch and operate network
services because network functions previously carried out be routers, firewalls, load
balancers and other dedicated hardware would now be hosted on virtual machines (VMs).
