QoS control: an application integrated framework

Abstract

Network technology is becoming simpler in order to support the widest possible range of user applications. Therefore, the specific requirements of each application must be performed outside of the network and the adaptation mechanisms should be done by the applications. For the case of multimedia applications the programming a task can even be more simplified if several "low-level" aspects can be made transparent by the use of a suitable framework. This paper presents such a framework with some algorithms to control some of the previous aspects, namely data handling and dynamic QoS control. It provides the application with a mechanism to constantly adapt the quality of the continuous media being transmitted. The algorithm takes into account not only the network conditions but the end host conditions as well. Some experiments are presented.
