USABILITY OF COMMUNICATION PERFORMANCE MODELS - A VIDEO-ON-DEMAND CASE-STUDY

Communication performance models enable networked multimedia applicati ons to describe their performance requirements as regards throughput, delay, jitter, and loss behaviour of a particular communication servic e. This paper presents four recently proposed models and demonstrates their usability with a video-on-demand example. The selected models ar e two models designed by the Tenet Group, one model on which ATM chann el traffic is characterized by the ATM Forum, and one model published as RFC1363 by the Internet community.
