Project Consortium • Telecom Companies: • T-Nova, Berkom (Germany), Co-ordination • Portugal Telecom (Portugal) • Manufactures: • Centre de Recherche de Motorola (France) • NEC (United Kingdom/Germany) • Alcatel SEL (Germany) • Research institute/University • Eidgenössische Technische Hochschule Zürich (Switzerland) • GMD Fokus (Germany) • University Madrid (Spain) • University Stuttgart (Germany) (RUS + IND) • University Cracow (Poland)
Objectives of Moby Dick • Development, implementation and test of end-to-end communication components based on the IP next generation (IPv6) • Support of • seamless vertical and horizontal hand-over mechanisms for and between different networks (e.g. UMTS, WirelessLAN and Ethernet). • QoS mechanisms based on the Internet Engineering Task Force (IETF) respectively Differentiated Services during times of QoS end-to-end connectivity without interrupts . • AAA mechanisms based on the Internet Research Task Force (IRTF) for different kind of access networks. • billing and charging mechanisms for IP QoS connections. • Local and international trials with ERASMUS exchange students (Students between Madrid/Spain and Stuttgart/Germany).
Detailed Workpackage Information (WP1) • Workpackage 1: Project Framework (Requirements, Applications and System Integration) • Definition and selection of end-user applications. • Definition and selection of: • QoS requirements in access networks and backbone - e.g. Differentiated Services (Layer3) or Multi Protocol Label Switching (Layer2). • Mobility requirements for vertical and horizontal hand-over mechanisms. • AAA and charging architecture for access networks and backbone. • Integration of the workpackages WP2, WP3 and WP4.
Detailed Workpackage Information (WP2, WP3 and WP4) • Implementation workpackages: • Workpackage 2: Quality of Service • Design, implementation and local testing. • Workpackage 3: Mobility • Design, implementation and local testing. • Workpackage 4: Authentication, Authorisation, Accounting and Charging • Design, implementation and local testing. • Implementation will be based on an Open Source Platform.
Detailed Workpackage Information (WP5 - WP6) • Workpackage 5: Integration, Validation, Evaluation and Trials • Co-ordination of the tests • WP5.1: first and local implementation tests. • WP5.2: second test with all components in one location. • Co-ordination of the final long distance trial with ERASMUS-exchange students (WP5.3). • Workpackage 6: Project Management and External Relations • Co-ordination of the project. • Establishing and maintenance of connections and co-operation with other IST project, EURESCOM project and standardisation bodies.

Future/First Steps - Conclusion Project’s contract preparation phase is not finished yet (middle of November). Planned start early next year (January 2001 or February 2001). Participation in standardisation bodies as soon as possible. Participation in IST clusters from the beginning. Close co-operation with other IST projects and Research and Development projects - world-wide.
