Note that this is from 2006. Do you have a link to the actual paper, by Terry Shaw, of CableLabs, and Jim Martin of Clemson ? Regards Marshall On Oct 21, 2007, at 1:03 PM, Sean Donelan wrote:

Based on the research, conducted by Terry Shaw, of CableLabs, and Jim Martin, a computer science professor at Clemson University, it only takes about 10 BitTorrent users bartering files on a node (of around 500) to double the delays experienced by everybody else. Especially if everybody else is using "normal priority" services, likee-mail or Web surfing, which is what tech people tend to call "best-effort" traffic.Adding more network bandwidth doesn't improve the network experience of other network users, it just increases the consumption by P2P users. That's why you are seeing many universities and enterprises spending money on traffic shaping equipment instead of more network bandwidth.
