This document is a primer on Network Functions Virtualization (NFV), outlining its definition, significance for telecom companies, and the role of open source technologies. NFV aims to replace specialized hardware with virtual machines for increased agility and reduced costs. It also discusses various aspects of NFV implementation, including virtualized infrastructure management and the importance of community collaboration in development.

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

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

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