Inferring the buffering delay of remote BitTorrent peers under LEDBAT vs TCP

Abstract : Nowadays, due to excessive queuing, Internet delays grow sometimes as large as the propagation delay from moon to earth -- for which the bufferbloat term was recently coined. Some points to active queue management (AQM) as its solution, others propose end-to-end congestion control techniques -- like BitTorrent that recently replaced TCP with the LEDBAT transport protocol. In this demo, we implement a methodology to monitor the upstream queuing delay experienced by remote hosts, both those using LEDBAT, through LEDBAT's native one-way delay measurements, and those using TCP, through the timestamp option. By actively taking part into torrent downloads as leechers, our software is able to infer (and visualize) the amount of access delay suffered by the remote peers.
