Active networks and high speed content delivery

Abstract

The best effort approach is typical for Internet data transmission since the early days. New kind of services, different application requirements, and real time data transport asked for a change in this model. ATM networks introduced several years ago included a Quality of Service model aimed to solve at least some of these requirements. However, the theoretical results in this field were too difficult to implement and nowadays ATM technology is used in backbones (if at all), but definitively not to user’s end machines and the QoS must be achieved by other means.
