4 Business Challenge #1 How do we carry network traffic profitably? Exponential increase in network traffic Driven by growth in video Ongoing increase in network equipment costs To address subscriber bandwidth needs Flat to declining per-user revenue (ARPU) Network cost increases are outpacing subscriber revenue growth Wind River.

6 Business Challenge #2 Who s extracting the most value from network traffic? OTT projected to cost service providers $14B in lost revenue in 2015 Up 26% from 2014 Social media, IM and VoIP are primary sources of lost revenue User loyalty and stickiness All about speed, agility, ease-of-use and innovative services Providing value to subscribers Wind River.

8 Business Challenge #3 IoT: A threat or an opportunity? Exponential growth in devices connected over service provider networks Corresponding increase IoT in traffic Critical demands on network capability Security Latency Availability How will service providers monetize IoT? Analytics, contextual-based services etc Wind River. All Rights Reserved.

16 Four Key Business Challenges for NFV Protecting top-line revenue during the transition to NFV Minimizing OPEX to fully leverage the benefits of NFV Gaining market share through accelerated deployments of new services Maximizing flexibility through adoption of open solutions Wind River.

17 Protecting Top-Line Revenue during the Transition Even with traditional physical infrastructure, network outages cause major revenue impact for service providers $15B per year (1% to 5% of revenues) Customer churn plus operational expenses plus SLA penalties Thousands of dollars per minute, per server Wind River.

18 Impact of Network Outages (Heavy Reading) Wind River. All Rights Reserved.

19 NFV Has the Potential to Make this Much Worse Traditional physical infrastructure typically delivers six 9s reliability ( % uptime) Carrier Grade reliability developed and proven over many years and thousands of deployments NFV adds significant risk factors New, virtualized network applications Dynamic reallocation of VMs across servers, racks and data centers Complex, hard-to-debug traffic flows Need to implement Carrier Grade reliability in NFV deployments Significant risk to service providers revenues if network uptime not maintained Wind River.

20 Enterprise Platforms Don t Provide Telco Reliability Fault detection (in hardware or virtualization layer) Detection of failed VMs Detection of failed platform management services vswitch performance Network link failure detection for compute nodes Live migration for DPDK-based VMs Enterprise IT Platform Capability ~ 1 minute > 1 minute No support 1-2 Gbps Depends on Linux distribution No support Carrier Grade Telecom Infrastructure Requirements Sub-second Sub-second < 10s Line rate with minimum core utilization 50ms Full support Network Reliability is Key to Commercial Success of NFV Wind River.

22 Minimizing Service Providers OPEX with NFV When cost-per-bit exceeds revenue-per-bit, networks are no longer profitable Cost-per-bit is exploding because of growth in video Revenue-per-bit is flat to declining because of competition and subscriber expectations NFV promises to address this through OPEX reductions Reduced network operations costs Lower cost-per-subscriber Need solutions that deliver these savings Despite the overhead of virtualized applications Wind River.

26 Maximizing Flexibility through Open Solutions Flexibility is key to leveraging full range of suppliers of NFV software Traditional TEMs unbundling their applications Open Software Network equipment suppliers introducing software versions of hardware solutions New ISVs with innovative products Service providers have well-defined requirements for open software Provided by company that is major contributor to open-source Fully-compatible with all relevant industry standards No vendor lock-in at component level Major open-source contributor No vendor lock-in on components Need a solution that checks all the boxes Standard APIs Wind River.
