Frameworks of Telecom and protect Environment Chaesub Lee Chairman of ITU-T SG13 Content 1. Frameworks of Telecom 2. Trends of Telecom 3. Protect Environment 4. Standard work 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 Hearing Touch Smell Taste 1. Frameworks of Telecom Objective of Telecommunication - 1 Minimum condition for building real society See Hearing Standard for Telecom Quality of Services 1.5 m 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 1. Frameworks of Telecom Basic Configuration of Telecommunication Wires Transmission Switching Systems Systems Transmission Systems Wires (User side) Terminal Systems Switching Systems Wires (Transmission) Terminal Systems 2. Trends of Telecom Trends of Telecom Network development Far Past : Seper. of Voice & Data Transp. Circuit Switch. Access Capa. Circuit Switch. Transp. Capa. Packet Switch. Transp. Capa. Past : Sep. of V & D Access Circuit Switch. Access Capa. Packet Switch. Access Capa. Circuit Switch. Transp. Capa. Packet Switch. Transp. Capa. xDSL / FTTx Future : Integration of V & D over FMC Present: Integration of V & D Transport Circuit Switch. Access Capa. (Fixed/Mobile) Packet Switch. Access Capa. (Fixed and Mobile Access) Packet Switch. Transp. Capa. Packet Switch. Access Capa. (Fixed/Mobile) Circuit Switch. Transp. Capa. Packet Switch. Transp. Capa. VoIP / VToA 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. 2. Trends of Telecom Overall NGN Architecture • NGN= Service Stratum + Transport Stratum • Basic Functions= User + Control + Management Applications ANI Management Functions Application Support Functions & Service Support Functions Service User Profiles Service Control Functions Service stratum Network Attachment Control Functions Transport User Profiles End-User Functions Resource and Admission Control Functions Other Networks Transport Control Functions Transport Functions UNI NNI Transport stratum Control Media Management 2. Trends of Telecom Enabling for Convergence Business/Application oriented projects Limited Services BE IP Limited BB FMC N G N •Simple linkage btw layers •Simple business relationships •Simple players RFID IPTV Others Managed IP Converged Broadband •Simple linkage btw layers with dynamics •Diverse and Flexible business relationships •Diverse business models and players 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 Healthcare Ind. Vehicle Ind. Merchand izing Ind. Education Ind. Travel Ind. others Move Off line to On-line Life (inc. Business) Using Energy ICTs Network Infras. 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 from BT: NGN impact overall network operation N G N 30 ~ 40% Reduction of Sites • • • • • • Resulting by More Broad bandwidth Extend Reachability Support Convergence Service vs. Transport Integrated Management 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 * ECO: Energy Cost saving Overlay * Ref: FGFN-C25 “Energy Saving Network Technologies”, Fujitsu Ltd, 11. 2009 4.
