What is NFV?
Wikipedia:
http://en.wikipedia.org/wiki/Network_Functions_Virtualization
“NFV is a network architecture concept that
proposes using IT virtualization related
technologies to virtualize entire classes of
network node functions into building blocks that
may be connected, or chained, together to create
communication services”

5. An NFV Primer5
What is NFV, in simple terms?
Telcos are replacing specialized hardware
with VMs running on commodity hardware

15. An NFV Primer15
Telco industry more competitive than ever
● Costs dominated by data
usage
● Customers expect more data
for less
● Demand for new services
increasing

Network functions

21. An NFV Primer21
“Middleboxes”
● Act on data going through the network
● Examples: Load balancer, gateway, IDS, VPN endpoint, NAT,
firewall
● Not just telco
