Agenda

1. What is NFV?2. Why are telcos investing in NFV?3. Open source for NFV4. Filling the gaps

1. What is NFV?

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

What is NFV, in simple terms?

Telcos are replacing specialized hardware with VMs running on commodity hardware

2. Why do telcos care?

Telco services - access

Dial-up

ISDN

ADSL

Cable

Fibre optic

3G/4G

Satellite

Telco services - applications

Voice

Internet/data

Live TV/streaming

VOD

DVR

TV Guide

SMS/MMS

Games

VoIP

Voicemail

Premium services

...

Telcos provide more services todaythan ever before

Telco industry more competitive than ever

Costs dominated by data usage

Customers expect more data for less

Demand for new services increasing

The promise of NFV

Increased agility

Reduced CapEx, OpEx

What is a network node function?

Network functions

Middleboxes

Act on data going through the network

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

Not just telco

3. Open Source and NFV

Why Open Source?

Cloud

Private cloud

DevOps and agile development

Open source drives the cloud
