AT&T has sent a cool response to the Vuze Corporation's "Plug-In" survey of ISPs, ranked by their median rate of TCP reset activity: "Given that Vuze itself has recognized these problems with the measurements generated by its Plug-In, we believe that Vuze should not have published these misleading measurements, nor filed them with the [Federal Communications Commission]." So AT&T Vice President Charles Kalmanek Jr. wrote to Vuze CEO Gilles BianRosa, following the P2P content provider's FCC filing last week. And AT&T insists that it does not insert false reset signals into P2P packets.

According to Vuze's filing, 8,000 people around the world installed the plug-in, and the company collected over a million hours of data about reset activity on various ISPs. Comcast topped the chart, with one of its local networks having a median reset rate of 23.72 percent. Cablevision came in eighth with 17.58 percent, AOL arrived at 20th, and an AT&T Worldnet Services network landed at 25th with a median rate of 13.97 percent.
