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

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

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,

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 selforganizing networking capabilities.
Help to grow the industry through a service architecture ecosystem of onestop-shopping solution for service specific challenges

STRATEGIC DIRECTION
• 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
GSC-18, 22-23 July 2014, Sophia Antipolis
17
CHALLENGES & HOT ISSUES
• The area is “hot” now!
• Is it a hype or here to stay?
• Too many SDOs involved
• Many overlaps expected
• Coordination?
• Realizing NFV requirements!
GSC-18, 22-23 July 2014, Sophia Antipolis
18
NEXT STEPS / ACTIONS
• 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
