  1. ATIS Software-Defined Networking/Network Functions Virtualization Mark Lipford, Director Global Standards and Ecosystem Development, Sprint GSC-18 Meeting, 22-23 July 2014, Sophia Antipolis, France

  2. Industry landscape • Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) are critical parts of a sweeping technology evolution from proprietary, specialized hardware solutions to commercial off-the-shelf-based hardware solutions. • Virtualized systems are enabled by frameworks that abstract hardware resources into a consistent operating environment for the software. • One of the most consequential impacts of this implementation is the ability to integrate and scale software with telecom-grade efficiency. • 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

  3. Highlight of Current Activities • The ATIS SDN/NFV Focus Group (FG) Phase 2 was launched in January 2014 to build on previous efforts in SDN, which resulted in ATIS’ Operational Opportunities and Challenges of SDN/NFV Programmable Infrastructure (October 2013). • The FG will conclude its work shortly to include: • An NFV global landscape • An analysis on inter-provider service chaining • Building on the work of the previous ATIS SDN FG and current SDN/NFV FG, ATIS is launching a comprehensive effort focused on inter-provider NFV open to interested stakeholders. GSC-18, 22-23 July 2014, Sophia Antipolis

  4. Strategic Direction 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 GSC-18, 22-23 July 2014, Sophia Antipolis

Challenges & Hot Issues Operations & Customer Care Operations & Customer Care SLA, Logs, Ticketing Back-Office Back-Office Ordering, Settlement Services Services IMS, CDN, SDN, Web Routing Routing Discovery, Policy Network Interconnection Network Interconnection MPLS, Ethernet, IP Provider-1 Provider-2 Cross Administrative Domain Service Function Chaining presents a multi-level challenge that can be addressed by interoperable NFV software primitives allowing for the delivery of many types of aggregated business applications. GSC-18, 22-23 July 2014, Sophia Antipolis

  7. Challenges & hot issues • End user applications are constructed with common service functions. • Product development puts away the blank sheet of paper and gets out the tool kit. • Developer communities accelerate the process by building third party apps that use the same APIs. • Network, identity, communications, OSS, and BSS services are frequently reused. • Exposing software infrastructure through multiple interfaces increases service utilization.
