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.

HIGHLIGHT OF CURRENT ACTIVITIES

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

• 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.

STRATEGIC DIRECTION

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

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

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.

CHALLENGES & HOT ISSUES

GSC-18, 22-23 July 2014, Sophia Antipolis 7

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.
