GSC-18, 22-23 July 2014, Sophia Antipolis 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 GSC-18, 22-23 July 2014, Sophia Antipolis

GSC-18, 22-23 July 2014, Sophia Antipolis 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.

GSC-18, 22-23 July 2014, Sophia Antipolis 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 GSC-18, 22-23 July 2014, Sophia Antipolis

GSC-18, 22-23 July 2014, Sophia Antipolis 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.

GSC-18, 22-23 July 2014, Sophia Antipolis 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 GSC-18, 22-23 July 2014, Sophia Antipolis

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 GSC-18, 22-23 July 2014, Sophia Antipolis

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 GSC-18, 22-23 July 2014, Sophia Antipolis
