			Abstract

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