1. What is NFV?

NFV and Open Source4

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”

NFV and Open Source5

What is NFV, in simple terms?

Telcos are replacing specialized hardware with VMs running on commodity hardware

NFV and Open Source6

2. Why do telcos care?

NFV and Open Source11

Telco services - access● Dial-up

● ISDN

● ADSL

● Cable

● Fibre optic

● 3G/4G

● Satellite

NFV and Open Source12

Telco services - applications● Voice

● Internet/data

● Live TV/streaming

● VOD

● DVR

● TV Guide

● SMS/MMS

● Games

● VoIP

● Voicemail

● Premium services

● ...

NFV and Open Source13

Telcos provide more services todaythan ever before

NFV and Open Source14

NFV and Open Source15

Telco industry more competitive than ever● Costs dominated by data usage

● Customers expect more data for less

● Demand for new services increasing

NFV and Open Source16

The promise of NFV

NFV and Open Source17

Increased agility

NFV and Open Source18

Reduced CapEx, OpEx

NFV and Open Source19

What is a network node function?

NFV and Open Source20

Network functions

NFV and Open Source21

“Middleboxes”● Act on data going through the network

● Examples: Load balancer, gateway, IDS, VPN endpoint, NAT, firewall

● Not just telco
