Comcast, under investigation by the FCC for throttling upstream P2P traffic with forged packets, fielded questions today at an FCC hearing at Harvard on traffic shaping. Comcast Executive Vice President David Cohen, using the stock semantic responses we're all familiar with by now, took aim at critics by suggesting that tests showing they forge TCP packets were "nothing more than a failed experiment." From PC Magainze:Interestingly, Cohen broke the news at the hearing that Comcast is currently under investigation by NY's Attorney General. If you recall, NY's AG recently busted Verizon Wireless for selling 5GB capped EVDO service as "unlimited." Comcast wisely stopped advertising their service as unlimited several years ago, in part thanks to our user reports that the company was booting high-consumption users from the network.

Interestingly, Broadband Reports user Robb Topolski, who was the first to discover the practice in May of last year (though the AP is often credited), continues to track Comcast's traffic shaping and says that Comcast appears to have backed off throttling Gnutella and EDDonkey traffic. However, Topolski says the company's effort to throttle BitTorrent seems to have actually doubled in recent weeks.
