Agenda

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

4. Filling the gaps


(ETSI #2)

VNF as a Service


Service Function Chaining


Virtualized Mobile Base Station

(ETSI #4)

● Deterministic latency● Accelerated dataplane

performance● Federation of multiple clouds● High performance signal

processing● IPv6 support


Resource reservation


Fault management
