  4. Reasons for a New Gbit/s-Network • Growing quantitative demands • national connectivity • traditional applications • new applications • distribution of intl. Traffic • Growing qualitative demands • flexible bandwidth assignment • CoS / QoS Requirements • Changes on the bandwidth market

  5. Traffic Analysis (1)

  6. Traffic Analysis (2) • Growing traditional traffic: (factor 2.2 pa) • Multimedia factor: 3-5 on monthly averages • consequence 1: number of high-speed accesses will grow over the years (technical perspective) • consequence 2: backbone has to be dimensioned according to the needs with only financial restrictions

  7. G-WiN Technology (1) • SDH /WDM platform for IP traffic • Point-to-Point service (flexible bandwidth provision) • 60 * 34 Mbit/s point-to-point available and switchable at any time • ATM Service (flexible bandwidth and QoSprovision) • within backbone flexible shifts of bandwidth according to changing user demands

  8. Technology (2) G-WiN Backbone Customer Router / ATM Switch Backbone Node (29)

  9. Future G-WiN-Services • Services Capacity (in Mbit/s) • Internet 0.128, 2, 34, 155, 622, 2400 • Point-to-Point 2, 34 • ATM 2, 34 • CoS / QoS • urgent need for a lot of applications • needs definition and organisational concepts for implementation

  10. The Procurement • European Tendering for winner • backbone Deutsche Telekom • access lines miscellaneous • router CISCO • transatlantic connectivity still open

  11. G-WiN Characteristics (1)Demand Forecast of access ports

  12. G-WiN Characteristics (2)Throughput main traffic hour

  13. G-WiN Characteristics (3)Number of Backbone Interfaces

  14. G-WiN Characteristics (4)Cost Diagram

  15. G-WiN Characteristics (5) • appropriate platform for traffic growth and for new user applications • Implementation of latest available technology (SDH / WDM, later end-to-end WDM) • appropriate cost/bandwidth curve on the ntl. scale, later (hopefully) Europe and US • available Q1 2000
