    Abstract

    This paper discusses a model for evaluating the quality of service (QOS) of a campus-wide network. The main goal is to achieve a mathematical model that can be applied to any network, providing its availability. The network where it will be tested has more than 5000 nodes with SNMP managed network devices. The model discards the classical approach to QOS that considers parameters such as delay or jitter. Instead, we evaluate quality as a function of the availability indexes for either the services or the network itself. Once the model is described, we will explain how it has been implemented at the Universitat Autònoma de Barcelona Campus network and the requirements - software and hardware - to install such a system in any network. © 2001 Elsevier Science B.V.
