Mission and Mandate of SG13
 Study requirements, architecture, evolution
and convergence of future networks
 Studies focused on
 network aspects of mobile telecommunication networks,
including International Mobile Telecommunications
(IMT),
 wireless Internet, convergence of mobile and fixed
networks,
 mobility management, mobile multimedia network
functions, internetworking, interoperability
 Enhancements to existing ITU-T Recommendations on
IMT.

Why new network?
 New network appears when important features
change
 Implementation technology, application, …
 It’s possible to use old one, but optimized one is
often more convenient and cheap
 We can access the internet with telephone & modems
 ??? Is it time to find a new network ???
NGN
 NGN features: packet-based, managed QoS, improved
security, separation of service/transport stratum, etc.
 These are good, may apply in the future, but the focus
may shift …?

Vision of Future Networks (Y.3001 –
Future Networks: Objectives and
Design Goals)
 Definition of FN:
A network able to provide services,
capabilities, and facilities difficult to
provide using existing network
technologies.
A Future Network is either:
a)A new component network or an enhanced
version of an existing one, or
b)A heterogeneous collection of new component
networks or of new and existing component
networks that is operated as a single network.

Social and
economic
awareness
Four Objectives
 Environment awareness
 FNs should have architecture that is
optimized to handling enormous
amount of data in a distributed
environment.
SOCIAL-ECONOMIC
AWARENESS
 Data awareness
DATA
AWARENESS
 FNs should provide services that are
customized with the appropriate
functions to meet the needs of
applications and users.
SERVICE
AWARENESS
 Service awareness
ENVIRONMENT
AWARENESS
 FNs should be environmental
friendly.
FUTURE NETORKS
 Social-economic awareness
 FNs should have social-economic
incentives to reduce barriers to
entry for the various participants of
telecommunication sector.
Committed to connecting the world
Design Goals, selection
 FNs should have device, system, and network level
technologies to improve power efficiency and to satisfy
customer’s requests with minimum traffic (Power
Consumption)
 FNs should have mechanisms for retrieving data in a timely
manner regardless of its location (Data Access)
 FNs should be designed to provide sustainable competition
environment to various participants in ecosystem of
telecommunication by providing proper economic incentives
(Economic Incentives)
 FNs should accommodate a wide variety of traffic and support
diversified services (Service Diversity)
 FNs should facilitate and accelerate provision of convergent
facilities in differing areas such as towns or the countryside,
developed or developing countries (Service Universalization)

Workshop
 Joint ITU-T SG13 and ISO/JTC1/SC 6 workshop on future
networks standardization
Geneva, Switzerland, 11 June 2012
 To identify commonalities and differences in the work
progressed by each group, and to assess if those
differences can be solved
 To investigate which standards would be developed as
common texts according to Recommendation ITU-T
A.23, Annex A | ISO/IEC JTC 1 Standing Document 3
 Workshop will be supported by remote participation
tools

Network Virtualization
 Network virtualization is the technology that enables the
creation of logically isolated network partitions over
shared physical network infrastructures so that multiple
heterogeneous virtual networks can simultaneously
coexist over the shared infrastructures.
 Also, network virtualization allows the aggregation of
multiple resources and makes the aggregated resources
appear as a single resource.
 The detailed definition and framework of network
virtualization are described in (ITU-T Y.3011 (01/12)
“Framework of network virtualization for future
networks”).
