Building a Society
 Basic & Fundamental need of all human being
 Need at least two people
 Need tools for communication (5 senses: See, Hearing, Touch, Smell, Taste)

2. Trends of Telecom
The vision of ubiquitous networking
Services on the Convergences
• 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
2. Trends of Telecom
Key Features of NGN
Next Generation Network (NGN):
ITU-T
Rec.
Y.2001
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.

Overall NGN Architecture
• NGN= Service Stratum + Transport Stratum
• Basic Functions= User + Control + Management

3. Protect Environment
Focal points on ICT & CC: support to protect environment
Protect
Natural
Environment
• Green House Gas emission
• Pollutions of natural environment: Air,
Water etc.
• Natural disaster: earth quake, fire, thnami
etc
• Other natural disaster
Impacts
Protect
Cultural
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. “Plannedprovisioning” 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
 Requirements (Operation, Planning and Functions)
 Capabilities for services and OAM&P (including QoS,
Security and Mobility etc.)
 Functions and features allocation into functions
impact
 Protocols (for example to support “Stand by” mode)
 System design and specification including power
feeding conditions
 others

3. Protect Environment
Example of candidate trials: ECO Networking Technology
 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
