Fabian Jäger: Bandwidth estimation in networks

The performance of a network depends on several conditions which are often not exactly measurable but can be approximated. These information are needed by administrators to scale a network or an

application which needs to adapt its behavior to the current network conditions. For example, the performance of many network applications like VoIP software or P2P content distribution systems depends heavily on the available bandwidth of the network. Therefore several tools are being developed to estimate the available bandwidth and capacity. They vary in used measurement technique and focus of measurement. All of these tools have in common that their accuracy and efficiency are still inaccurate. This paper reviews, evaluates and discusses several papers about this issue.
