Mobility and Differentiated Services in a Future IP Network IST 2000 key action line IV 5.2 “Terrestrial Wireless System and Networks”. The project Moby Dick defines, implements, and evaluates an IPv6-based mobility-enabled end-to-end QoS architecture starting from the current IETF's QoS models, Mobile-IPv6, and AAA framework. A representative set of interactive and distributed multimedia applications serve to derive system requirements for the verification, validation, and demonstration of the Moby Dick architecture in a testbed comprising UMTS, 802.11 Wireless LANs and Ethernet.
