DFN Association: Targets

• Higher Education and Research (universities, research institutes)

• Institutions with close relationship to the research and education com-munity

• Research departments of industry

• Government agencies

DFN Association: Objectives

• Provision of national and inter- national connectivity

• Bundling the requirements of the community to achieve better com- mercial conditions on the market

• Testbeds for next generation communication technologies

• Promotion of new applications

• Organisation of international collaboration

DFN Association: Finance

• Non-profit organisation

• Subsidies from federal government only for development projects and for start-up phase

• Operational cost (capacity, equip- ment, personnel, services ...) must be fully covered by income: charges for services

G-WiN Technology (1)

• WDM/SDH platform for IP traffic

• Point-to-Point service (flexible capacity provision)

• ATM service (flexible capacity and QoS provision)

G-WiN Technology (2)

• Within backbone flexible provision of capacity according to changing user demands, lead time 1 hour

• up to 60 * E3 point-to-point connections switchable at any time

• provision of larger capacities within six weeks

G-WiN Technology (3)

Customer Router

Backbone Router (28)

G-WiN Backbone

G-WiN Services (1)

• Available services - Access to backbone from E1 up to OC-48 - Point-to-Point at E1, E3 - ATM at E1, E3

• CoS / QoS: under way - urgently needed for many appli- cations - required: service definition and organisational concepts

G-WiN Services (2)

• DFNInternet: nat‘l connectivityand global

transit

• DFNConnect: point-to-point service

• DFN-ATM: ATM-service atadditional charge

• Add. Services: at additional charge (QoS, ...)

Procurement

• European Tendering for

lot awarded to - backbone Deutsche Telekom - access lines various companies - routers Cisco - transatlanticDeutsche Telekom connectivity

G-WiN Characteristics

• Suitable platform for future traffic growth and for high performance applications

• Implementation of latest available field proven technology, now SDH/WDM, later WDM end-to-end

• Reasonable cost/bandwidth relation

• Availability of „protected“ connec- tions for specific applications and experiments (point-to-point service)

International Connectivity

• Capacity to US now 2 * OC-12 (into Telehouse, NYC)

• Capacity to TEN-155 upgraded to OC-12

• Access to Abilene in NYC at 100 Mbps, together with DANTE

• Access to Canarie in NYC at 15 Mbps, together with DANTE
