Migration of Networks
• A network could not replaced by another a network at one-shot completely.
• A new network adopt several new technologies and relevant systems including
their operation and provisioning.
• Though several technologies including systems will remain a new network.

Definition and scope of SUN
“Smart ubiquitous networks are IP-based packet networks that can
provide transport and delivery a wide range of existing and emerging
services to people and things. The services provided by the networks can
cover aspects such as control, processing and storage. The networks are
smart in the sense that they are knowledgeable, context-aware,
adaptable, autonomous, programmable and can effect services
effectively and securely. The networks are ubiquitous in the sense that
they allow access anytime anywhere through varied access technologies,
access devices including end user devices, and human-machine
interfaces.”

4 Objectives and 12 Design goals of FN-1
Future Network (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.

4 Objectives and 12 Design goals of FN - 2
Social and economic awareness: reduce barriers to entry for the various actors involved in the network
ecosystem and reduce their lifecycle costs, thus will help to universalize the services and allow appropriate
competition and an appropriate return for all actors.
1) Service universalization: facilitate and accelerate provision of facilities in differing areas such as
towns or countryside, developed or developing countries, by reducing lifecycle costs of the network and
through open network principles.
2) Economic incentives: be designed to provide a sustainable competition environment for solving
tussles among the range of participants in the ICT/telecommunication ecosystem—such as users,
various providers, governments, and IPR holders—by providing proper economic incentive.
[Rationale]IP layer did not provide a means to its upper layer to know if QoS was guaranteed from end-to-end. They also lacked proper economic
incentives for the network providers to implement them. Coupled with other reasons, these have provided obstacles for introduction of QoS
guarantee mechanisms and streaming services in IP networks, even when telecommunications ecosystem participants have tried to customize
networks or asked others to provide customized networks to start a new service and share its benefits.
Environmental awareness: be environmentally friendly.(minimize environmental impact including reduce
the environmental impact of other sectors)
1) Energy consumption: use device-, equipment-, and network-level technologies for improvement of
energy efficiency and satisfaction of customers’ demands with minimum traffic. FN device-,
equipment-, and network-level technologies are recommended to not work independently, but cooperate
with each other as a total solution for network energy savings.
2) Optimization: provide sufficient performance by optimizing network equipment capacity based on
service requirement and user demand and perform various optimizations within the network with
consideration of various physical limitations of network equipments.
4 Objectives and 12 Design goals of FN - 3
Data awareness: handling enormous amounts of data in a distributed environment, and enable users to access
desired data safely, easily, quickly, and accurately, regardless of their location. In the context, “data” is not limited to
specific data types like audio or video content, but describes all information accessible on a network.
1) Data access: be designed and implemented for optimal and efficient handling of huge amounts of data and
have mechanisms for promptly retrieving data regardless of their location.
2) Identification: provide a new identification structure that can effectively support mobility and data access in
a scalable manner.
Service awareness: provide services whose functions are designed to be appropriate to the needs of applications and
users.
1) Service diversity: support diversified services accommodating a wide variety of traffic characteristics and
behaviors and support a huge number and wide variety of communication objects such as sensors and terminal
devices.
2) Functional flexibility: offer functional flexibility to support and sustain new services derived from user
demands and support agile deployment of new services keeping pace with their rapid growth and change.
3) Virtualization of resources: associated with networks in order to support partitioning of resources, and a
single resource can be shared concurrently into multiple virtual resources and support isolation of any virtual
resource from all others and support abstraction in which a given virtual resource need not directly correspond
to its physical characteristics.
4) Network management: be able to efficiently operate, maintain, and provision the increasing number of
services and entities and to process massive amounts of management data and information efficiently and
effectively transform these data to relevant information and knowledge for the operator.
5) Mobility: provide mobility that facilitates high-speed and large-scale network in an environment where a
huge number of nodes can dynamically move across heterogeneous networks and support mobile services
irrespective of node’s mobility capability.
6) Reliability and security: be designed, operated, and evolved with reliability and resilience considering
challenging conditions and be designed for safety and privacy of their users.

Evolution trend of Networks from NGN to FN through SUN
 Expectation for the new key network technology such as for transport layer will be
envisioned with FN development (until that time, IP will be kept asps)
 But developments of networking capabilities shall be continued and “smart” is one of
important theme

Position of SUN
 SUN could be identified as an enhanced (or beyond) of NGN with enhanced
networking capabilities but keeping IP as a dominant network technology
 SUN also could be identified as an early realization of FN with its networking
capabilities will be core part of FN while observe these when adopt new network
technology (e.g., “not IP” at this stage)
