"Comcast's network management practices (1) only affect the protocols that have a demonstrated history of generating excessive burdens on the network; (2) only manage those protocols during periods of heavy network traffic; (3) only manage uploads; (4) only manage uploads when the customer is not simultaneously downloading (i.e., when the customer's computer is most likely unattended) ("unidirectional sessions" or "unidirectional uploads"); and (5) only delay those protocols until such time as usage drops below an established threshold of simultaneous unidirectional sessions."

Meanwhile, in Congress, Reps. Markey and Pickering have revived the idea of a Net neutrality law, which would demand that Comcast and other ISPs refrain from "unreasonable discriminatory favoritism" in what content they allowed to pass through their networks freely. Rep. Markey failed to get a net neutrality bill passed two years ago, at which time it was opposed by Rep. Pickering. The new bill (PDF here) does not specify any requirements or penalties, merely suggests neutrality as a stated policy. Apparently that change was enough to satisfy Rep. Pickering's objections.CNET News, CNET News
