NFV for Beginners

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”

Hold on... what is NFV, again?

ETSI architecture

No, really... what is NFV?

Telcos are replacing hardware with VMs

Telco services

● Dial-up● ISDN● ADSL● Cable● Fibre Optic● Broadband● Satellite

● Voice● Internet/data● Live TV● VOD● Cellular voice● SMS/MMS● Cellular data● Games● ...

13

Telcos provide more services todaythan ever before

14

15

Telco industry more competitive than ever

● Margins decreasing● Maintenance costs increasing● Customer demand for new services increasing

16

Telcos care because:

● Increased agility – more services to market faster● Reduced CapEx – replace expensive custom H/W

with industry standard servers● Promise of reduced OpeEx

Revisiting definition of NFV

“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”

Wikipedia:http://en.wikipedia.org/wiki/Network_Functions_Virtualization

19

What is a network node function?

20

“Middleboxes”

● Act on data going through the network● Examples: Load balancer, gateway, IDS, VPN

endpoint, NAT, firewall● Not just telco stuff

21

22

Top use-cases

● IMS, EPC, SDB: Cellular, telephone, TV, video streaming, VoIP, 3G/4G data

● CPE: Customer Premises Equipment – telco equipment on-site (set-top boxes)

● Many others to choose from!

23

Why now?

Open source

Cloud computing

SDN

24

ETSI

● ETSI NFV ISG = European Telecommunications Standards Institute NFV Industry Standards Group

● Defines use-cases, terminology and interfaces for a hypothetical NFV platform

● NFV white paper and use-cases seeded both OPNFV and OpenStack NFV team

http://www.etsi.org/technologies-clusters/technologies/nfv

25

OPNFV

● Linux Foundation hosted project● Goal is to create a complete software stack for

NFV– Technology gaps – write code where needed for

NFV

– Upstream first – evangelise NFV to upstream projects, ensure code is accepted

Upstream first

● Fill technology gaps – code talks● Get that code upstream – Minimum Viable Delta● Promote NFV use-cases in relevant upstream

projects

30

OpenStack NFV team

● NFV needs high performance● Requires getting information about, and utilizing,

underlying hardware and software● “Pets vs Cattle” debate

31

What's next?

● First OPNFV release Q1 2015● Prioritising projects and use-cases● OpenStack Kilo summit in Paris
