1 5G: The Software Network and Virtualization Opportunities J-L. Beylat, VP European programs, Bell Labs, Alcatel-Luc

2 Challenging scenarios

3 WHAT ARE WE TRYING TO BUILD? THE HIGHEST PERFORMANCE NETWORK? (BW, Latency, Availability, Programmability) THE LOWEST COST PER BIT NETWORK? (Capex, Opex, inc. Energy) THE MOST PERSONALIZED NETWORK? (User-optimized, Predictive, Sentient?) ALL OF THE ABOVE BUT WHY? 3

4 TO SERVE HUMAN NEEDS Hierarchy of Human Needs (Based on Maslow Model) And help others achieve too And feel that we have achieved something To allow time to appreciate life And knowledge & wisdom To acquire status and respect And connect, communicate & collaborate Securely To live 4

5 WE NEED TO BUILD THE NETWORK OF YOU THAT Allows you to connect, communicate and collaborate with PEOPLE PLACES POSSESSIONS 5

6 WE NEED TO BUILD THE NETWORK OF YOU THAT Creates time by creating a virtual you but how and when? 6

9 THE UBB FUTURE: SOLVING THE RADIO CAPACITY PROBLEM 2x 10x more 3x more 2x MORE SPECTRAL EFFICIENCY (Bits/Sec/Hz) MORE SPECTRUM (Hz) 5G WIRELESS CAPACITY MORE SPATIAL EFFICIENCY (Bits/Sec/Hz/User) >10x THE FUTURE OF WIRELESS IS SMALL...AND WIRED (CONVERGED) 3x more 9 N

10 Broadband efficiency Integrate all available spectrum New air IF Licensed, Shared & Unlicensed spectrum Mm-wave MORE SPECTRUM (Hz) Smart approaches: - target user experience - cross- layer optimization --> Less bits per service Unified framework for multiantenna Efficient support (massive) MIMO MORE SPECTRAL EFFICIENCY (Bits/Sec/Hz) INCREASE CAPACITY MORE SPATIAL EFFICIENCY (Bits/Sec/Hz/User) Small cells Flat architecture Interference handling One step: Integration of design

11 THE UBB FUTURE: THE WIRELINE ANSWER CO-Home Distance (km) Mbps per subscriber Mbps per subscriber (DS) Node-Home Distance (km) x MORE SPECTRUM (Hz) EFFICIENCY EFFICIENCY (Bits/Sec/Hz) (Bits/Sec/Hz/User) 2x MORE SPECTRAL WIRELINE CAPACITY DS/US ratio MORE SPATIAL 5x LOWEST COST PER MBPS/SUB LOWEST COST PER MBPS/SUB 100 ADSL2+ DOCSIS Bonded 3.1 ADSL2+ (WITH NODE SPLITS) FTTLA VSDL2 FTTH (GPON) VDSL2 + Vectoring BondedVDSL2 + Vectoring 1 GPON/G.Fast Bell Labs Modeling THE FUTURE OF WIRELINE IS DEEP FIBER...

13 THE REVOLUTION: SOFTWARE-DEFINED NETWORKS CREATE & EXPOSE VIRTUAL PRIVATE NETWORKS (OF VNFs AND PNFs) SDN NFV CREATE & MANAGE VIRTUAL NETWORK FUNCTIONS (VNFs) SCALE THE BUSINESS SCALE THE NETWORK AND NETWORK FUNCTION VIRTUALIZATION

14 WHY NFV? VIRTUALIZED APPLICATION PHYSICAL INTERFACES TOR APP VM VSWITCH HYPERVISOR Application A SWITCH STORAGE SERVER SERVER SERVER Application B Application C MEMORY NETWORK PROVIDER DATA CENTER COMPUTE SERVER SERVER SERVER Application(s) X IT DATA CENTER SERVER CARD

15 WHY & WHEN NFV?
