Client-Network Interactions in Quality of Service Communication Environments

Multimedia communication, with its strong requirements for high speed, assured quality , and reliable networking, is stimulating a great research eeort towards the development of real-time protocols. Some protocols of this type have been proposed, which ooer communication services with diierent levels of commitment in providing quality of service guarantees. In this paper we study the feasibility of an extended client interface that allows more exibility in the client-network interactions. The proposed model improves the utilization of network resources, and increases the network's capability to support multimedia traac, while continuing to ooer a guaranteed quality of service.
