   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
     • 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
     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
