Although this report shouts the headline "we dont throttle" the body of the report indicates thats not what AT&T said.
http://www.news.com/8301-10784_3-9929158-7.html?part=rss&subj=news&tag=2547-1_3-0-5AT&T on Friday denied using forged reset packets to interfere with network connections of Vuze file-sharing platform users, as Comcast has been accused of doing with BitTorrent traffic.
The statement came in response to a report released earlier this week (PDF) by Vuze, which offers a BitTorrent-based client primarily used for distributing video. The start-up has asked the Federal Communications Commission to impose regulations prohibiting broadband operators from blocking or degrading peer-to-peer traffic.
Vuze's report claimed to document the median reset rates experienced by more than 1,200 "autonomous system numbers," which are unique identifiers for individual IP networks and routers, as monitored using a plug-in Vuze began offering last month. (It tracks all possible network interruptions, not just ones related to the Vuze platform.)
According to Vuze's data, a number of Comcast connections recorded the most frequent interruptions, but the top 20 highest reset rates also included users with Cablevision, BellSouth (an AT&T property), and AOL subscriptions.
I think the primary topic here is when will it be possible to obtain information on "network management" technologies prior to signing a ISP service contract that barely touches on the issue if its mentioned at all, this is the real scandal we face as filesharers.
