SG ON SECURITY, RELIABILITY, AND PERFORMANCE FOR SOFTWARE DEFINED AND VIRTUALIZED ECOSYSTEMS
• Objective• Identify primary standards development opportunities in the
reliability, performance, and security aspects of the SDN, NFV, NGSON, and related areas
• Scope:• Priority class of service virtualization: intersection of reliability,
security, and performance circles• Use case & application driven; regulated industry• Metrics

RG ON SOFTWARE DEFINED AND VIRTUALIZED WIRELESS ACCESS • Objective:
• Identify and address research issues that need to be solved and assess the feasibility of launching an IEEE standardization on this area
• Scope:• Extending SDN to devices (mobile) at the network edge; separation of
data and control planes• Use of SDN to control and program network resources (e.g, SDN – SDN
Network Controller), Joint optimization of transport and RAN• Heterogeneous multi-owner multi-vendor RAN control and Management
(eg, CRAN, Ethernet Based included, softRAN)• Interoperability among layers 1 to 3 (programmable data path)• Extracting and managing information to enable wireless
networks control; mechanisms (how); what? KPIs
(Contact: Fabrizio Granelli, Chair <[email protected]>) 8
RG ON ABSTRACTION – STRUCTURED NETWORK OBJECTS (SNO)”
• Objective:• identify and formulate possible IEEE standardization efforts to define
a high-level taxonomy and structure that represent the network and its functions.
• Scope:• identify the object structure needed for standardizing interfaces and
descriptors for SDN and NFV.• Define common high level taxonomy, structure• PNF Descriptor• Network Model, Service model • Data Model, Object model
(Contact: Ken Kerpez, Chair <[email protected]>)

SG ON SERVICE VIRTUALIZATION
• Objective:• Leverage the existing body of work by IEEE P1903 Next Generation
Service Overlay Network (NGSON) Working Group on next generation service overlay networks and define service specific functions for virtualization and softwarization.
• Scope:• NGSON, SDN, NFV Coordination• Programmability• Service Routing - Not limited to Data packets• Triggers based on contexts from users, device, service, and network
(Contact: Mehmet Ulema, Chair, <[email protected]>)

HIGHLIGHT OF CURRENT ACTIVITIES
• Existing projects – IEEE P1903 (NGSON)• An IEEE sponsored effort to standardize a framework of IP-based
service overlay networks • A set of context-aware, dynamically adaptive, and self-organizing
networking capabilities, including advanced routing and forwarding schemes
• Motivation:• Exponentially increasing number of services and applications and their
interactions
• To have a better, more “efficient” way of providing these services and applications by means of context-aware, dynamically adaptive, and self-organizing networking capabilities.
• Help to grow the industry through a service architecture ecosystem of one-stop-shopping solution for service specific challenges

STRATEGIC DIRECTION
GSC-18, 22-23 July 2014, Sophia Antipolis
• SDN and NFV and related areas has been identified as one of IEEE Future Directions.
• Significantly increase IEEE standardization activities in this area within the existing projects and with new projects
• Establish liaisons with other SDOs working on this area
17
CHALLENGES & HOT ISSUES
GSC-18, 22-23 July 2014, Sophia Antipolis
• The area is “hot” now! • Is it a hype or here to stay?
• Too many SDOs involved• Many overlaps expected• Coordination?
• Realizing NFV requirements!
18
NEXT STEPS / ACTIONS
GSC-18, 22-23 July 2014, Sophia Antipolis
• SGs are expected to generate PARs and new WGs are expected to be formed in less than 6 months
• RGs are expected to generate white papers that may be used in launching new standardization activities
