8. 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

9. 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

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

11. Limited BB BE IP Limited Services NGNNGN Converged Broadband Managed IP FMC RFIDIPTV Others Business/Application oriented projects 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 Enabling for Convergence 2. Trends of Telecom

12. 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 Protect Natural 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 Protect Cultural Environment Impacts 3. Protect Environment

13. 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 Using Energy Move Off line to On-line Life (inc. Business) Network Infras. ICTs Vehicle Ind. Health- care Ind. Merchand izing Ind. Travel Ind. Education Ind. others 3. Protect Environment

14. 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

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

16. 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 3.
