To support the requirements of future emerging applications and users,
telecommunications technologies beyond current IP oriented technologies will
need to be developed. The Future Network (FN), which is anticipated to provide
futuristic functionalities beyond the limitation of the current network
including Internet, is getting a global attention in the field of communication
network and services. There are growing concerns with respect to the following
aspects of the current network, including IP based networks:
scalability/ubiquity, security/robustness, mobility, heterogeneity, Quality of
Service (QoS), re-configurability, context-awareness, manageability,
data-centric, network virtualization, economics, etc. Also, the Future Network
will be more deeply incorporated and composed with new emerging technologies and
services, such as intermittent network capabilities, DTN
(Delay/Disruption-Tolerant Networks), vehicular/airborne networks, programmable
and cognitive radio networks, network virtualization, etc.
These topics will be considered during the development of the requirements
for Future Networks, which aim to meet future services and overcome the
deficiencies of the current IP based networks. It is also recognised that
backward compatibility with existing network and systems technologies may not
need to be considered.
Not only for cooperation among the experts from all interested parties but
also for ensuring global interworking possibilities among the future networks
and systems, it is necessary to start new standardization work on future
networks technologies which may provide a new paradigm beyond current
telecommunication technologies including IP. This work will need to be
accomplished in cooperation with other standards bodies as appropriate.
The Question is intended to study a how a futuristic architecture and a
framework, which includes high level requirements and functional architecture
and use cases and services, meets the new Future Network requirements.
Study items to be considered:
- Problem statements on current IP-based network architecture (which should
consider the current vision of future services and applications)
- Design goals and general requirements for the Future Network (scalability,
transparency, multi-homing, traffic engineering, mobility, security, robustness,
re-configurability, context-awareness, manageability, heterogeneity,
data-centric, and economics)
- Gap analysis between existing standards and/or proposals for next generation
networks and the design goals and requirements for the Future Network (FN)
- Study of Meta architectures (network virtualization, cross-layer
communications) and architectural framework for the Future Network (e.g.
wireless, advanced photonics, embedded computing, intermittent network/DTN,
vehicular/airborne network, programmable and cognitive radios, network
virtualization, overlay service control)
- Study on how to incorporate new communication and service technologies into
Future Networks, such as wireless edge network (e.g. mesh/sensor, ad-hoc,
network movement) or optical backbone network (e.g. optical switch or router).
- Identify functions and capabilities necessary to support new services for the
Future Network (e.g. user-centric, context-aware, user's preferences
considering, proactive users provisioning, seamless services, QoS)
- What enhancements to existing Recommendations are required to provide energy
savings directly or indirectly in Information and Communication Technologies (ICTs)
or in other industries? What enhancements to developing or new Recommendations
are required to provide such energy savings?
Tasks include, but are not limited to:
- Produce document(s) on vision and service scenarios of future networks as
well as on problem statements of current and evolving networks and systems.
- Produce inputs to new Recommendations on:
- requirements of the future networks, which provide enhanced features as well
as on gap analysis between existing technologies including recent evolving
technologies and the requirements of future networks.
- framework and model of future networks, which may provide a common basis for
further development of specific recommendations on functions and facilities.
- Collaborate with other standards bodies e.g. ISO/IEC JTC 1/SC 6 on future
networks (including the possible development of common text standards for both
standardization bodies where appropriate).
