The report by Measurement Lab, a Google backed platform, reveals that hundreds of ISPs across the globe are involved into throttling of peer-to-peer traffic and that too specifically BitTorrent traffic. The Glasnost application run by the platform helps in detecting whether ISPs shape traffic and tests can be carried out to check whether the throttling or blocking is carried out “on email, HTTP or SSH transfer, Flash video, and P2P apps including BitTorrent, eMule and Gnutella”.
Going by country, United States has actually seen a drop in throttling compared to its figures in 2010 says the report. Throttling in US is worst for Cox at 6 per cent and best for Comcast, Verizon, AT&T and others at around 3 per cent. United Kingdom is seeing a rise in traffic shaping and BT is the worst with 65 per cent. Virgin Media throttles around 22 per cent of the traffic while the least is O2 at 2 per cent.
Canada may be considered anti-BitTorrent traffic country with its two top ISPs Roger and Bell shaping up to 80 and 77 per cent traffic respectively. The least is Telus with no traffic shaping at all.
European countries seem to be adopting a ‘let it be’ stance and countries like Sweden, France, Italy, Spain and Poland haven’t been shaping up the traffic that heavily.
Japan is also showing signs of heavy throttling with two of its ISPs Japan Infoweb Fujitsu and J:COM shaping up 60 and 83 per cent traffic.
