Distributed active measurement of Internet queuing delays
Résumé
Despite growing link capacities, over-dimensioned buffers are still
causing, in the Internet of the second decade of the third millenium, hosts to
suffer from severe queuing delays (or bufferbloat). While maximum bufferbloat
possibly exceeds few seconds, it is far less clear how often this maximum is hit
in practice. This paper reports on our ongoing work to build a spatial and temporal map of Internet bufferbloat, describing a system based on distributed agents
running on PlanetLab that aims at providing a quantitative answer to the above
question.
