Supporting Quality of Service Guarantees Across Heterogeneous Lans
Developments in multimedia workstations and high speed networks, and advances in digital audio/video compression technology, make possible new classes of distributed applications, eg. distance learning, video-conferencing and remote multimedia database access.The communications needs of these applications will lead to a diversity of traffic types with various Quality of Service (QoS) requirements such that new classes of communication services will be required to support this new traffic. Digitised audio and video traffic are generally classified as continuous media. Continuous media place a high demand on both the network and the workstation, requiring not only high throughput, but also timely delivery. Therefore communications performance and predictability are important issues, particularly if these new applications are to be provided with a guaranteed QoS.
