7. 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
(Contact: Spilios Makris, Chair ,

8. 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

9. 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

10. 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,

11. 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
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, July 2014, Sophia Antipolis

18. 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, July 2014, Sophia Antipolis

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