REPORT FROM SESSION #2: SDN/NFV
Andrew White, ATIS Vice President of Technology and Standards
GSC-18 Meeting, 22-23 July 2014, Sophia Antipolis, France
SDN/NFV SUMMARY - IEEE
• New initiatives:
• “Rapid Reaction Standardization Research Team” meeting held on
April 25, 2014
• 16 attendees from 7 companies (operators, manufactures, others),
2 universities, worldwide representation
• 17 gap items identified, 4 new groups formed:
• Study Group (SG) on Security, Reliability and Performance for Software Defined
•
•
•
and Virtualized Ecosystems
Research Group (RG) on Software Defined and Virtualized Wireless Access
Research Group (RG) on Structured Abstractions
Study Group (SG) on Service Virtualization
• New work under existing IEEE projects
• IEEE P1903 – Next Generation Service Overlay Networks (NGSON)
• IEEE P802.1CF OmniRAN Task Group

SDN/NFV SUMMARY - ATIS
ATIS has identified common principles providing insight into
important aspects of SDN/NFV as a foundation for shaping its
program:
• Focus on the interoperability and interworking between
service providers
• Engage web-scale companies with easy-to-use capabilities
• Develop services that enable and enhance the user
experience
• Preserve and enhance the value of the network
The industry is facing a software skills gap with the move from
hardware-based solutions to software-based solutions.

SDN/NFV SUMMARY - TTC
• Application Driven Thinking
• Top-down dynamic update of software
• User, app, device, service-oriented modeling
• Deep (Data Plane) Programmability
• SDN data plane as a network function in NFV
• Data plane slicing (virtualization)
• Evolve-able APIs
• New protocol handling
• Programming Model
• Toy-Block Networking
• Accommodate a wide range of programmers
• Marketing of reusable network functions blocks

SDN/NFV SUMMARY - TTA
• SDN/NFV standardization in software platform and relevant
interfaces are actively in progress but that of hardware
platform is relatively in active. For open hardware platform
standardization requires attention
• Transport SDN seems a common interest as a high priority
item among fixed or wireless carriers. Faster standardization
efforts may help the relevant industry
• Standardization of SDN South/North-bound APIs are under
active progress but East-West interface needs coordination
• Autonomic management and control (AMC) in relation with
SDN/NFV are also attracting attentions for cloud data center
management and M2M/IoT infrastructure management.

SDN/NFV SUMMARY - ETSI
• Tremendous amount of work achieved
• Big, well established and very active community
• First results published (6 docs), major step forward.
• Next results stabilized (17 docs), pub 2014Q4
• This is just a start
• Next step
• Focus on interoperability through normative specs and tests
• Cooperate to accelerate
• Implementation in specific Use Cases (relevant to 3GPP, BBF,
Linux foundation,…).
Remain the “centre of gravity” for the global industry to collaborate on NFV

OBSERVATIONS AND
RECOMMENDATIONS
In an effort to enhance global cooperation and collaboration
regarding SDN/NFV standards the panel identified the following
common views and collaboration opportunities:
• User experiences are driven by applications. Build networks
that support integrated and trustworthy delivery of services
• Software solutions are dominating and recognized as not
only a means to reduce expenses but to creating new value
• Deeper programmability within the network should bring
innovative new services
• Application use cases of SDN and NFV should drive
identification and clarification of necessary extensions to the
current SDN and NFV

OBSERVATIONS AND
RECOMMENDATIONS
• Each SDO is completing a gap analysis of the SDN/NFV
landscape. Using this activity to gain common perspective
results in more effective collaboration
• Coordinate the development of distributed SDN/NFV
standards and software to promote a cohesive framework
• Sharing views and directions among related SDOs is
necessity to accelerate synergy and to avoid overlapping
efforts and to define the overall landscape
• A software skills gap exists as a result of the move from
hardware-based solutions to software-based solutions
