2. Trends of Telecom
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
2. Trends of Telecom
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.

2. Trends of Telecom
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

3. Protect Environment
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

3. Protect Environment
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)
Others
impact
Requirements (Operation, Planning and Functions)
Capabilities for services and OAM&P (including QoS, Security and Mobility etc.)
Functions and features allocation into functions
Protocols (for example to support “Stand by” mode)
System design and specification including power feeding conditions
others
3. Protect Environment
Example from BT: NGN impact overall network operation
NGN
Resulting by• More Broad bandwidth• Extend Reachability• Support Convergence• Service vs. Transport• Integrated Management• Others
30 ~ 40%Reduction of Sites
3. Protect Environment
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
