Abstract

There are various parameters for analyzing the quality of network communication links and paths, one attracting particular attention is available bandwidth. In this chapter we describe a platform for the available bandwidth estimation, a comparison of different tools for the estimation of this parameter, and an application of such estimation in a real-world application. In details, we describe a novel platform called UANM, capable of properly choosing, configuring, and using different available bandwidth tools and techniques in an autonomic fashion. Moreover, thanks to UANM, we show the results of a comparison of the performance of several tools in terms of accuracy, probing time and intrusiveness. Finally, we show a practical example of the use of the available bandwidth measurement: we describe an approach for server selection and admission control in a content distribution network based on the available bandwidth estimation.
