2. Unprecedented  
   Traffic  Growth  
   Orders  of  
   magnitude  
   increase  in  users,  
   devices,  apps  
   Video,  Mobile  
   traffic  exploding  
   CAPEX    
   conDnues  to  rise  
   “DATA” ERA
   “VOICE” ERA
   TRAFFIC
   OPERATOR COST
   REVENUES
   * Graph Source - Accenture Analysis
   NEW SERVICES
   IP Video: 79% of all
   IP traffic in 2018
   AT&T spends $20 Billion
   per year on CAPEX
   Service  Provider  Networks  
   2016 traffic = triple of 2011 More mobile
   devices than people
   Time
   Growth
   Explosive growth in Service Provider networks

3. Scale
   Open Monetize
   Reduce CAPEX and OPEX
   Deliver new and
   customized
   Services rapidly
   Bring in cloud-style agility,
   flexibility, Scalability
   Lower operational complexity,
   increase visibility
   •  Open APIs
   •  Multi-vendor
   •  Multi-technology
   •  Open Source
   Turning growth into opportunity

13. Number of Instances in Cluster
    Latency
    10 ms
    What’s good enough? Simple Rule of thumb
    •  1  M  flow  ops/sec    
    •  Less  than  100ms  latency  (ideally  under  10ms)
