• Big sales projections 2018 sales of SDN systems to service providers will reach $15.6 billion, up from just $626 million last year (ACG)
NFV revenue could rise to $1.9 billion in 2019 from $203 million this year (Mind Commerce)
• Both NFV and SDN currently seen as cost saving solutions (Current Analysis 60 SPs)
• SDN

• Clearly impacting network vendors Need to become more open
Value is in the s/w not the h/w
Strong emphasis on orchestration s/w and services engagement
• Will impact Service Providers SPs completely get NFV, many struggle with SDN
Could be argued that both NFV and SDN increase complexity rather than reduce it
SPs need to re-organize to bring compute and n/w together
Old n/w skills remain, however need new skills (cloud and s/w development)
Need to maintain carrier class reliability
Mix of existing processes combined with DevOp processes

Strengths
 
Weaknesses
• High packet processing • Specialized SP design and h/w functionality • High physical interface counts (>20s) • High interface speeds (>40G) • Diverse interfaces types • Infrastructure functions
• High capacity plumbing and gateways : Custom built combination (NPU / fixed ASIC / GPP)
• Elastic service functions combined with low-medium packet processing : virtualized GPP
• CPU intensive tasks : virtualized GPP

The Key Takeaways of this presentation were:
• 3 broad categories in Device Programmability Portfolio (1) Config/Operate Interfaces, (2) Device Extension APIs and (3) DevOps Plug-ins
• Positioning of technologies – Each category solves different use cases and are complimentary
• Programmability architecture is evolving with common data models as the foundation. These data models are exposed via NETCONF YANG, REST and Python API
• onePK Device Extension API will GA on all platforms and continue for targeted device extension use cases
• Open Flow 1.3 support will focus on Internet2 and SLED segment
