Future directions in NGN standardization
Yogyakarta, Indonesia, 27-29 July 2009 8
Overall future directions
Yogyakarta, Indonesia, 27-29 July 2009 9
“Convergence” is a key goal of the future
Future should direct to “Convergence”• Vision is “Any Time, Any Where, Any Services and
Any Devices”• Towards Any services over Any transport
infrastructures
Convergence • Internal to an industry (e.g. FMC, IPTV)• Among different industries (e.g. Telematics/ITS, USN, e-Health, etc.)
Yogyakarta, Indonesia, 27-29 July 2009 10
•Always on with Any devices•Anytime, anywhere and in Any form•Voice and multimedia•Self service, intuitive•Simple for the end user•Secure, trusted and reliable
Services at “Convergence” time

“Ubiquitous Networking”
o Enabling “Any Service, Any Time, Any Where, Any Device” operations via enhanced NGN capabilities
o Support of human-to-human, but also human-to-machine and machine-to-machine communications

Technical areas
Yogyakarta, Indonesia, 27-29 July 2009 15
o The NGN infrastructure needs enhancements in order to support a larger set of applications and business scenarios• Telco oriented services (such as Voice, Data and Video streaming),
as well as dynamic Information services (e.g. WS, P2P, USN)• Customized/personalized services using advanced capabilities in
service delivery and control (e.g. context awareness)• 3rd Party Providers’ apps/scenarios, User created apps,
Interconnect scenarios with Home Networks & Enterprise Networks • Composite applications “mashing-up” capabilities from different
domains (Telecom/IMS, Internet/Web 2.0, Content) -> NGN service platform
• Applications over NGN integrated with other industries such as Transport Systems, Robotics, Health, Education etc.
o Also, current standards generally lack of clear indication on how these should be used for support of specific application scenarios• E.g. more study required on service delivery and control (IPTV etc.)
The evolved NGN will have to support a larger set of applications and business scenarios
Yogyakarta, Indonesia, 27-29 July 2009 16
o Support of Convergence o FMC capabilities don’t provide full service level supporto More detailed developments are necessary (e.g. support of seamless handover with what service and what level)
o Support of Composite serviceso Mechanisms are required for service delivery across different
domains, including for Service Quality Mgt and Policy Mgto Accessibility of enablers to third partieso Orchestration of common service functions
o Identity Management features completeness o Integrated Identity Processing (across identity domains), standards
for interoperability and User control of Personal Ident. Info (PII)o Policy management consistency
o Required across access technologies, across Service and Transport o Support of Multi-domain/multi-network services
o More work required on Security, QoS, User profiles, Content Mgt, Interconnection etc.
Standardization of NGN capabilities: some challenges
Yogyakarta, Indonesia, 27-29 July 2009 17
o Integration of new technologies with NGN o P2P (Q.19/13 DSN), Grid, etc.
o Integration of social requirementso Environmental sustainability, accessibility
o Interoperabilityo Promotion of interoperability is required developing mechanisms
which facilitate it o IMS-based NGN
o It is needed to ensure the value proposition of IMS-based NGN for providers and users (e.g. integrating IMS assets in a NGN service platform)
o Migration to NGNo More work is required to identify best “common” practices for
migration towards identified target NGN configurations
Other NGN challenges

develop the future Internet architecture through a clean slate approach.
o Small scale, but a large number of projects converge into a fewer number of full scale architectures
o To verify using GENI
GENIo Aimed at developing a
testbed organization to succeed Planet Lab’s development. programmable

o FIRE: Future Internet Research and Experimentation
o FIRE’s goal is to build a dynamic, sustainable, large scale European Experimental Facility
GEANTo EC’s research networko Upgrading and greater
capacity in its third term (GEANT3)
Yogyakarta, Indonesia, 27-29 July 2009 20
o The title of SG13 in the new study period (2009-2012) is “Future Networks including Mobile and NGN” reflecting the importance of “Future Networks”
o A specific new Question on Future Networks has been approved as Q21/13o Future Networks have become part of the global agenda: national and regional
initiatives (US, EU, China, Japan, Korea), as well as international ones (IRTF and, more recently, ISO/IEC JTC1/SC6)
o The academic community expressed strong interest in collaborating with the ITU-T on this subject during the ITU-T Kaleidoscope May 2008 event
o However, all ongoing activities seem to be in an early stage of investigation/development
o Global harmonization among all these different activities is important and essential to build up globally interoperable future ICT infrastructures
o ITU-T intends to make all efforts to support the development of global and harmonized frameworks (e.g. requirements, functional architectures and protocols) collaborating with all relevant worldwide organizations/projects/FN communities
o Initial collaboration items (in progress) include • Collection and identification of various visions of future networks from relevant
organizations/projects• Establishment of a shared roadmap of standardization for Future Networks
Background and rationale of FG-FN creation
The ITU-T Focus Group on Future Networks (FG-FN) (established in Jan 09) – 1
Yogyakarta, Indonesia, 27-29 July 2009 21
The Focus Group, by collaborating with worldwide future network (FN) communities (e.g., research institutes, forums, academia and etc), aims to• collect and identify visions of future networks, based
on new technologies • assess the interactions between future networks and
new services • familiarize ITU-T and standardization communities with
emerging attributes of future networks • encourage collaboration between ITU-T and FN
communities
Scope of FG-FN
The ITU-T Focus Group on Future Networks – 2
Yogyakarta, Indonesia, 27-29 July 2009 22
The main objective of the Focus Group is to document results that would be helpful for developing Recommendations for Future Networks.
To achieve this objective the Focus Group will:
• gather new ideas relevant to Future Networks and identify potential study areas on Future Networks
• describe visions of Future Networks• identify a timeframe of Future Networks• identify potential impacts on standards development • suggest future ITU-T study items and related actions
Objectives of FG-FN
The ITU-T Focus Group on Future Networks – 3
Yogyakarta, Indonesia, 27-29 July 2009 23
o Review related research and standardization activities;
o Based on this review, produce the following deliverables:
• Future network benefits• Future network vision• High-level description of Future Networks
attributes• Vocabulary
Specific FG-FN tasks and deliverables
The ITU-T Focus Group on Future Networks – 4
Yogyakarta, Indonesia, 27-29 July 2009 24
An initial (DRAFT) definition of ‘Future Networks’ developed by Q.21/13 :
[Note: the clean-slate approach is understood as a designprinciple, not as deployment one]
o Future Network (FN) is a network which is able to provide revolutionary services, capabilities, and facilities that are hard to provide using existing network technologies.Note: FN provides mechanisms that benefit every participant as much as they contribute. It will be studied based on clean-slate approaches.

o The NGN standardization activity has almost completed the basic initial steps, but much remains to be done
• Evolution of NGN: ongoing and future working directions in order to support new and varying customer needs, and a larger set of applications and business models
• Challenges and requirements in numerous (new) areas o A growing interest (and funding) in Future Networks
within the worldwide research community• Harmonization of activities is essential for globally
interoperable future ICT infrastructures• Standardization should start as early as possible when
targeting the future social infrastructure• The ITU is taking an active role in promoting global
and harmonized frameworks and a shared standardization roadmap for Future Networks
