2 Agenda 1. What is NFV? 2. Why are telcos investing in NFV? 3. Open source for NFV 4. Filling in the gaps 2

3 1. What is NFV? 3

4 What is 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: 4

5 What is NFV, in simple terms? Telcos are replacing specialized hardware with VMs running on commodity hardware 5

6 2. Why do telcos care? 6

11 Telco services - access Dial-up Fibre optic ISDN 3G/4G ADSL Satellite Cable 11

12 Telco services - applications Voice SMS/MMS Internet/data Games Live TV/streaming VoIP VOD Voic DVR Premium services TV Guide... 12

13 Telcos provide more services today than ever before 13

14 14

15 Telco industry more competitive than ever 15 Costs dominated by data usage Customers expect more data for less Demand for new services increasing

16 The promise of NFV 16

17 Increased agility 17

18 Reduced CapEx, OpEx 18

19 What is a network node function? 19

20 Network functions 20

21 Middleboxes Act on data going through the network Examples: Load balancer, gateway, IDS, VPN endpoint, NAT, firewall Not just telco 21
