Abstract

Multimedia applications have intrinsic quality of service (QoS) requirements. However, a quantitative evaluation of the QoS offered by the network is rarely realized. Furthermore, the traditional methods for ensuring an end-to-end QoS rely on mechanisms provided by the distribution network. In this paper we propose a new quantitative QoS model that is validated by extensive experimental characterization of the QoS dependence on traffic parameters. This model is then used to design a QoS restoration technique that is independent of special resources available in the distribution network.
