Bell defends throttling practices

The Canadian Radio-television Telecommunications Commission (CRTC) is currently investigating Bell's system, which cap throttles P2P downloads at around 30KB/s between 4:30pm and 2:00am every day. Bell's own congestion numbers, which the CRTC said must be made public and Bell has now provided to Ars Technica, show that as the DPI gear was more widely deployed across Bell's network and eventually applied to Bell's wholesale customers (who promptly filed a complaint with the CRTC), rates of congestion at the DSLAM level increased. Between March 2007 and September 2007, the number of congested DSLAM links on Bell's network averaged 4.8 percent; during the period from November 2007 to May 2008, that average increased to 6.7 percent.
