  1.    ONOS     The  open  SDN  Network  Opera1ng  System

     for  Service  Providers                                      Prajakta  Joshi                                            Director,  Products  @  ON.Lab  
  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

  9. ONOS – SDN NOS For Service Providers •  Scalability,  High

     Availability  &  Performance     •  Northbound  &  Southbound  Abstrac1ons     •  Modularity  
  10. Key metrics for ONOS •  Performance   •  Topology  change

     latency   •  Topology  change  throughput   •  Northbound  latency   •  Northbound  throughput   •  Scale-­‐out   •  Ability  to  scale  control  plane  by  adding  capacity   •  High  Availability   •  Uninterrupted  opera1on  in  the  wake  of  failures,   upgrades   Challenging  part  -­‐>  providing  performance,  scale-­‐out,  HA  together  
  11. 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)
