QOS-BASED ROUTING OF MULTIMEDIA STREAMS IN COMPUTER-NETWORKS

Continuous media such as audio and video require a certain quality-of- service (QoS) when transferred through computer networks, The selectio n of a network route for a particular media stream should hence take i nto account which route is best-suited for providing this QoS, QoSFind er is a method for QoS-based routing of multimedia streams, It is base d on a path vector protocol that takes into account throughput, delay, and loss rate of individual route segments. A simulation of QoSFinder shows that its heuristic is superior to metrics that are only based o n one of these parameters. QoSFinder increases the probability of find ing suitable paths through networks for distributed multimedia applica tions.
