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. Is this called Network A? This may called Network A+ or beyond Network A

Smart + Ubiquity Features IP-based packet transport (i.e. NGN transport) QSM 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.” Service stratum + Transport control Definition and scope of SUN Q: Quality S: Security M: Mobility

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.

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 - 2

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. 4 Objectives and 12 Design goals of FN - 3

Extension of NGN (Beyond NGN) Early realiz. of FN 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) Indicate possible dis-continuty might happened
