The vision of ubiquitous networking

•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 on the Convergences


Key Features of NGN

ITU-T

Rec.

Y.2001

Next Generation Network (NGN): a packet-based network able to provide telecommunication services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies.

It enables unfettered access for users to networks and to competing service providers and/or services of their choice. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users.

•Simple linkage btw layers with dynamics•Diverse and Flexible business relationships•Diverse business models and players

Enabling for Convergence


Focal points on ICT & CC: support to protect environment

• Green House Gas emission• Pollutions of natural environment: Air,

Water etc.• Natural disaster: earth quake, fire,

thnami etc• Other natural disaster

ProtectNatural

Environment

•Historical monuments•Artistic items: Paints, Sculptures etc.•Musical items: Musical instruments etc.•Literary items: Books, Records etc.•Infrastructural items: Building of

Museum, Theater for Performance etc.

•Other cultural environments

Impacts


Way of using Energy is one of the major key concerns• ICTs itself are subject for control of Energy (generation and consumption)• ICTs will impact on using Energy (Delivery & consumption control)• Network infrastructure in the core of ICTs

Energy considerations aspects of Network

Planning aspects: for example “Over-provisioning” vs. “Planned-provisioning” and others

Operation aspects: for example “Always on” vs. “Stand by” and “Best effort” vs. “Managed” and others

Service aspects: Single media vs. Multimedia, Single service vs. Binding services or Convergence between different service environments

System aspects: Data storages, OAM&P systems, Router, Switch, Transmission systems, Duct operation, Emergency Power Feeding and others

Office operation aspects: Number of Offices and people within offices, Office operation related systems (e.g. lights, ventilation, cooling, Heating and others)

Capabilities for services and OAM&P (including QoS, Security and Mobility etc.)

Example from BT: NGN impact overall network operation

NGN

Resulting by• More Broad bandwidth• Extend Reachability• Support Convergence• Service vs. Transport• Integrated Management• Others

Example of candidate trials: ECO Networking Technology

* Ref: FGFN-C25 “Energy Saving Network Technologies”, Fujitsu Ltd, 11. 2009

ECO Routing Aggregate traffic into energy-

saving path Implement sleep mode for

routers where possible

ECO Switching Forward packets on timeslot

basis with time scheduling Buffer-less forwarding without

packet loss No routing table necessary

* ECO: Energy Cost saving Overlay
