  2. 2. 2 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”
  3. 3. 3 Hold on... what is NFV, again?
  4. 4. 4 ETSI architecture
  5. 5. 5 Lost in a sea of acronyms NFV MANO VIM VNFiEPC IMS SBC ETSI NFV ISG MMEvCPE CDN DPI IPSec SLA CG-NAT AAA SGSN PDN-GW RNC eNode B QoE BNG VPN HLR/HSS OSS/BSS BRAS C-RAN VNFs
  6. 6. 6 No, really... what is NFV? Telcos are replacing hardware with VMs

  12. 12. 12 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. 13. 13 Telcos provide more services today than ever before
  14. 14. 14
  15. 15. 15 Telco industry more competitive than ever ● Margins decreasing ● Maintenance costs increasing ● Customer demand for new services increasing
  16. 16. 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

  18. 18. 18 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. 19. 19 What is a network node function?
  20. 20. 20 “Middleboxes” ● Act on data going through the network ● Examples: Load balancer, gateway, IDS, VPN endpoint, NAT, firewall ● Not just telco stuff
  21. 21. 21
  22. 22. 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. 23. 23 Why now? Open source Cloud computing SDN
  24. 24. 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. 25. 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 http://www.opnfv.org

  29. 29. 29 Upstream first ● Fill technology gaps – code talks ● Get that code upstream – Minimum Viable Delta ● Promote NFV use-cases in relevant upstream projects
  30. 30. 30 OpenStack NFV team ● NFV needs high performance ● Requires getting information about, and utilizing, underlying hardware and software ● “Pets vs Cattle” debate
  31. 31. 31 What's next? ● First OPNFV release Q1 2015 ● Prioritising projects and use-cases ● OpenStack Kilo summit in Paris
