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. This book 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. This text should provide a useful reference for all professionals, engineers and researchers working in the area of high-speed networks.
