Bell Responds to Throttling Concerns

The Montreal Gazette features a series of MP3 recordings of an interview with Bell's Mirko Bibic on the throttling issue.


  1. Timothy Friesen says:

    Feeling a little confused…
    From the article:

    \”What we\’re doing is trying to take objective measures. We\’re not targeting particular people or particular content, we\’re directing these measures at a particular type of traffic. It\’s not slowing down peer-to-peer for everyone. … It\’s actually the P2P by heavy users, whether or not they\’re on Sympatico or on the wholesale ISP. And at that, it\’s only during so-called peak periods. Those who use P2P to a reasonable degree are not affected.\”

    They are \”directing these measures at a particular type of traffic\” but \”not slowing down peer-to-peer for everyone\”. Does this mean Bit Torrent is throttled but not something like Kazaa? He goes on to say \”it\’s actually the P2P by heavy users\” (all Bit Torrent users?)when just before that he said \”we\’re not targeting particular people\”. So what exactly are they throttling? Protocols (Bit Torrent?), traffic (P2P), or specific users that over-utilize their connection compared to the average user?

  2. mr peepers says:

    I always find the claim that ‘95% of users do not use P2P applications’ confusing since literally 95% of the people I know use P2P on a regular basis including my parents who are in their late-50’s and not all that computer savy at all. Perhaps they are referring to 95% of the entire population of Canada, not just Bell DSL users ūüôā

  3. 30 kilobits = 3.75 kilobytes
    Bibic said in the interview that anybody that consumes more than 30 Kb (killobits) is a bandwidth hog. This is 3.75 killobytes.

    You are paying $50 for dialup. $2.4bn in infrastructure investment? Shenanigans.

    I’m am completely unsurprised by the findings of the World Economic Forum. I’m loathe to be within a continent of Bibic and Bell.

  4. bandwidth is not constrained
    The bandwidth between your house and the local DSL center might be a little constrained, but the bandwidth for the backbone is quite underused. Basically, as I understand it, a fiber based backbone’s bandwidth is primarily limited by the ability of the laser to turn off and on quickly, as well as the sensitivity of the receivers to multiple wavelengths are the same time.

    Our backbone is currently fairly underused, and if it ever becomes a choke point, increasing it’s available bandwidth is easier and cheaper than increasing the bandwidth of every single dsl connection.

    Another point of interest- there are ways to increase the efficiency of P2P applications quite significantly. Check out the work Comcast has been doing in the states. They’re calling it P4P I think… in any case, it uses the available bandwidth more efficiently by prioritizing geographically close connections.
