5 Trend 1 Infrastructure Costs for NGA Infrastructure costs for Next Generation Access (NGA) are significant 1,200 Vectored VDSL Investment per Home Connected* Service provider competition is beneficial for consumer and for innovation Required investment per home connected drops as take rate grows 1, High density Medium density Low density 25% 50% 75% Take rate *ASSIA analysis based on data from Analysys Mason, WIK-Consult, and other public sources Sharing of the NGA infrastructure by multiple service providers reduces the investment per home connected and promotes service innovation 5

6 Trend 2 Evolution of Broadband Services Number of devices per household is growing Streaming traffic is dominating By 2017, there will be 5 devices per connection for every internet user Cisco VNI Global IP Traffic Forecast, (2013) Consumers look at more than broadband speed: Quality of service, on-demand services, home network quality 6

7 Trend 3 Software-Defined Networking Telefonica Network Virtualization Presentation, ETSI NFV ISG, February 2014 Telco players Very intensive in hardware Capital intensive Software is not a core Internet players Very intensive in software Can have global impact with not too much capital Hardware is a support, and is located in the network periphery AT&T Domain 2.0 Vision White Paper, November 2013 Open Provide APIs, enable better participation of third parties, and improve visibility. Increase the number of suppliers and partners AT&T can do business with. Simplify Weed out complexity from services and operations; support more nimble business models. Scale Meet evolving customer requirements including traffic growth, diversity of traffic types, and diversity of performance and reliability expectations. Improve business efficiency in capital and operations. Service providers expect software-defined networking to deliver interoperability, service agility, and lower costs 7

8 Software-Defined ACCESS Networking Physical Access Network Virtual Access Network Broadband Network Gateway (Operator A) Broadband Network Gateway (Operator B) Broadband Network Gateway Virtual Network Operator A Aggregation Switch Virtual link DSLAM Virtual DSLAM The Physical Access Network is mapped to a Virtual Access Network controlled by a Virtual Network Operator 8

9 Access Network Virtualization Architecture 1 OSS Virtual Network Operator A Infrastructure Provider Virtual Network Operator B Virtualization and Management Northbound Interfaces Diagnostics Analytics Optimization Database Northbound Interfaces Diagnostics Analytics Equipment Interfaces Northbound Interfaces Diagnostics Analytics Optimization Multi-tenant Management System Access Network The Multi-tenant Management System includes Management Functions specific to the Virtual Network Operators and the Infrastructure Provider 9

10 Access Network Virtualization Architecture 2 Virtualization Management and OSS Virtual Network Operator A Diagnostics Analytics Optimization Northbound Interfaces Infrastructure Provider Diagnostics Analytics Northbound Interfaces Virtual Network Operator B Diagnostics Analytics Optimization Northbound Interfaces Database Equipment Interfaces Access Virtualization System Access Network Management Functions specific to the Virtual Network Operators and the Infrastructure Provider are outside the Access Virtualization System 10

11 Capabilities for Virtual Network Operator (1) Configure DSL Profiles (within agreed envelope) Data collection schedules Service product definitions Stability (QoS) definitions Service qualification rules Service optimization rules (within agreed envelope) Recommendation engine rules The Virtual Network Operator has the freedom and responsibility to specify services within an agreed envelope 11

12 Capabilities for Virtual Network Operator (2) View and Analyze Collected data (DELT, SELT, MELT) Diagnostics Service recommendations Profile optimization history Recommendations for contact center and field force Analytics for network operations and marketing The Virtual Network Operator can view and analyze its own virtual network Data about other virtual networks are hidden or obfuscated 12

13 Capabilities for Virtual Network Operator (3) Act in Real-Time Port reset Forced profile change Real time data collection (DELT, SELT, MELT) Real time diagnostics Real time recommendations for contact center and field force Real time profile optimization The Virtual Network Operator can act in real-time to address service problems with no intervention of the infrastructure provider 13

14 Operational Benefits Issue Resolution Fault Analysis Type of fault Location of fault Time of degradation Source of disturbance Broadband Network Gateway Aggregation Switch DSLAM Routers (DSL, WiFi) and Connected Devices Virtual Network Operator Access Node Provider Metallic Path Provider Virtual Network Operator Responsibility for issue resolution is clearly assigned Costs and delays from unnecessary escalations are avoided Operational costs from unnecessary 14

15 Operational Benefits Customer Self-Help Service Management System Home Network Management System Access Management System Cloud-based system obtains real-time data Customer Network Management System Customer can apply recommendations in real-time Performance metrics Speed Quality Real-time/history Per line/device Per segment Per service type Recommendations Reset Optimization Home wiring Set preferences WiFi network Network operator The Virtual Network Operator gives real-time information and controls Many issues can be diagnosed and addressed by the customer 15

16 New Services Service Differentiation Service Product Dimensions Speed Devices Apps Support Smart TV Streaming Premium Mobile offloading Gaming Self help M2M Cloud apps Wiring insurance Dynamically affect access configuration and policy The Virtual Network Operator can offer products optimized for the mix of devices, for typical applications used, and for desired support level 16

17 New Services Services with a Time Dimension Service Scheduling Service On-demand Service configuration follows specified schedule Service configuration changes for short period 7am 5pm 5pm 8pm 8pm 7am (school days) Home office profile Family entertainment profile Internet off for kids devices Optimizing for UHD The Virtual Network Operator can offer scheduled or on-demand services such as speed boost, device prioritization and application optimization 17

18 New Services Service Sharing Mobile customer off-load WiFi sharing Cellular Base-station Device of Mobile Customer Fixed Line Customer A Device of Customer A Fixed Line Customer Fixed Line Customer B Optimizing for UHD Mobile device offloaded to WiFi access point Fixed line reconfigured for additional traffic Mobile device uses both fixed line connections Fixed line reconfigured for additional traffic The Virtual Network Operator can offer bandwidth boost services with WiFi sharing or ease cellular network congestion with mobile off-loading 18

19 Summary Industry Trends Infrastructure sharing Proliferation of devices and growth of streaming services Software defined networking Architectures Virtualization layer maps physical access network to virtual access networks Option 1 is for access management in single multi tenant system Option 2 is for access management independently implemented Benefits Simpler issue resolution between virtual network operators and infrastructure providers Enablement of customer self help options New Services Services optimized for devices, applications and support level On demand and scheduled services Service sharing 19
