Quality of service support of distributed interactive virtual environment applications in IP networks

This paper reports on the performance of Distributed Interactive Virtual Environment (DIVE) applications, deployed through Internet. Our goal is to understand the behaviour of a DIVE application, its interaction with competing traffic streams, as well as its network resource requirements for a satisfactory performance. As DIVE is becoming the building block of new applications and services, impacting several existing or new and growing sectors of our economy (email electronic commerce, tele-training, transportation), it is important that we understand the resource requirements of these applications, as well as the "stress" they will impose on the network.
