The Internet is subject to permanent modi?cations and to continuous restr- turing. This is primarily due to the tremendous rise in demand for bandwidth by the ever increasing number of users. When compared to the early years of the Internet the quality of the services o?ered had to be signi?cantly improved in di?erent respects (delay, network and service availability, jitter,. . . )inorder to satisfy the needs of many new applications. Within the last decade two new developments have contributed to many new opportunities, as well as to a need for intensive research and development: - the increased mobility of users together with the desire for ubiquitous hi- quality access to all o?ered services, at reasonable cost; - the use of wireless communication. Despite their relatively low capacity (when compared with ?xed backbone n- works) the use of radio links supports the ubiquitous availability of Internet services in a quasiperfect way. A considerable amount of research and development activities are currently - ing on worldwide in order to adapt Internet services to the particular needs of mobile users and of wireless communication links. These questions were - tensively discussed at the ?rst workshop organized by the EURO-NGI Network of Excellence ('Next Generation Internet'), which has been funded by the - ropean Union since January 2004 under their IST programme.

Multimedia data streams will form a major part of the new generation of applications in high-speed networks. Continuous media streams, however, require transmission with guaranteed performance. In addition, many multimedia applications will require peer-to-multipeer communication. Guaranteed performance can only be provided with resource reservation in the network, and efficient multipeer communication must be based on multicast support in the lower layers of the network. Architecture and Protocols for High-Speed Networks focuses on techniques for building the networks that will meet the needs of these multimedia applications. In particular two areas of current research interest in such communication systems are covered in depth. These are the protocol related aspects, such as switched networks, ATM, MAC layer, network and transport layer; and the services and applications. Architecture and Protocols for High-Speed Networks contains contributions from leading world experts, giving the most up-to-date research available. It is an essential reference for all professionals, engineers and researchers working in the area of high-speed networks.
