Demonstration of TADA: A tool for automatic detection of AQM

Abstract

Active Queue Management (AQM) and solutions to the bufferbloat problem have gained a huge attention in the research community, but it is unknown to what extent such solutions are currently deployed on the Internet. In this paper, we present a demonstration of a tool, called TADA, for automatic detection of AQM on a transmission path bottleneck. We have developed an active measurement tool for Linux, which is not only able to detect the presence of an AQM between a client and a server instance of the tool, but which can also detect the type of AQMs (from a selection of AQM families). TADA relies on active measurement and is able to accurately detect the AQM type in unloaded or lightly loaded bottleneck conditions. For this demonstration, we will allow users to change parameters for loss rate, number of flows competing on the bottleneck, serial bottleneck configuration, FIFO or AQM type on the bottleneck and observe the changes/performance of the tool under different settings.
