Abstract
During the last few years the Internet has grown tremendously and has penetrated all aspects of everyday life. Starting off as a purely academic research network, the Internet is now extensively used for education, for entertainment, and as a very promising and dynamic marketplace, and is envisioned as evolving into a vehicle of true collaboration and a multi-purpose working environment. Although the Internet is based on a best-effort service model, the simplicity of its packet-switched design and the flexibility of its underlying packet forwarding regime (IP) accommodate millions of users while offering acceptable performance. At the same time, exciting new applications and networked services have emerged, putting greater demands on the network. In order to offer a better-than-best-effort Internet, new service models that offer applications performance guarantees have been proposed. While several of these proposals are in place, and many QoS-enabled networks are operating, there is still a lack of comprehension about the precise requirements new applications have in order to function with high or acceptable levels of quality. Furthermore, what is required is an understanding of how network-level QoS reflects on actual application utility and usability. This document tries to fill this gap by presenting an extensive survey of applications ’ QoS needs. It identifies applications that cannot be accommodated by today’s best-effort Internet service model, and reviews the nature
