Frameworks of Telecom and protect Environment

1. Frameworks of Telecomand protect Environment Chaesub Lee Chairman of ITU-T SG13

2. Content • Frameworks of Telecom • Trends of Telecom • Protect Environment • Standard work

3. 1. Frameworks of Telecom 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) See Smell Taste Hearing Touch

4. 1. Frameworks of Telecom Objective of Telecommunication - 1 • Minimum condition for building real society See Hearing Standard for TelecomQuality of Services 1.5 m

5. 1. Frameworks of Telecom Objective of Telecommunication - 2 • Objective of Communication: Building virtual society using communication services/systems similar as real society 1.5 m

6. 1. Frameworks of Telecom Basic Configuration of Telecommunication • Wires • TransmissionSystems • SwitchingSystems • TerminalSystems SwitchingSystems TransmissionSystems Wires (Transmission) Wires (User side) TerminalSystems

8. 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

9. 2. Trends of Telecom Key Features of NGN 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. ITU-T Rec. Y.2001

10. 2. Trends of Telecom • NGN= Service Stratum + Transport Stratum • Basic Functions= User + Control + Management Overall NGN Architecture

11. 2. Trends of Telecom Business/Application oriented projects FMC RFID IPTV Others Managed IP N G N Converged Broadband Enabling for Convergence Limited Services BE IP Limited BB • Simple linkage btw layers • Simple business relationships • Simple players • Simple linkage btw layers with dynamics • Diverse and Flexible business relationships • Diverse business models and players

12. 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

13. 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 Move Off line to On-line Life (inc. Business) Using Energy Health-care Ind. Vehicle Ind. Education Ind. Travel Ind. Merchandizing Ind. others ICTs NetworkInfras.

14. 3. Protect Environment • 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 Energy considerations aspects of Network • 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 impact

15. 3. Protect Environment Example from BT: NGN impact overall network operation N G N • Resulting by • More Broad bandwidth • Extend Reachability • Support Convergence • Service vs. Transport • Integrated Management • Others 30 ~ 40% Reduction of Sites

16. 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 * ECO: Energy Cost saving Overlay * Ref: FGFN-C25 “Energy Saving Network Technologies”, Fujitsu Ltd, 11. 2009
