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
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

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.

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.
