In the field of network monitoring and measurement, the efficiency and accuracy of the adopted tools is strongly dependent on structural and dynamic characteristics of the network scenario under measure and on manual fine tuning of the involved parameters. This is, for example, the case of the end-to-end available bandwidth estimation, in which the constraints of the measurement stage vary according to the use of the final results. In this paper, the authors present UANM (Unified Architecture for Network Measurement), a novel measurement infrastructure for an automatic management of measurement stages, tailored to the end-to-end available bandwidth estimation tools. They describe in details its architecture, illustrating the features they introduced to mitigate the problems affecting available bandwidth estimation in heterogeneous scenarios.
