ty (the QoS-A project) on an architectural approach to integrated QoS support for multimedia communications. 2 D. Hutchison, G. Coulson, A. Campbell and G.S. Blair 11.1. Introduction Recent years have seen dramatic advances in computer communications technology. At the network level, new high-speed technologies such as FDDI, DQDB and, most recently, ATM-based networks are becoming available. These networks not only have the capability to transmit information at high speed, but also offer a range of properties including bounded delay, guarantees on throughput and isochronous communications. Multimedia workstation technology for generating, compressing and displaying streams of digital video and audio is available in the marketplace in a range of price/performance categories, along with very high capacity storage systems such as CD-ROM. These technological developments are complemented by new user perspectives. New classes of distributed application are being de
