A handful of consumer groups, including members of the Savetheinternet.com coalition, have asked the Federal Communications Commission to stop Comcast from interfering with BitTorrent and other P2P traffic. A new complaint (PDF) filed by Public Knowledge and Free Press accuses Comcast of “secretly degrading” P2P traffic, calling it a violation of network neutrality principles, and asks the FCC to enjoin Comcast from blocking P2P traffic in the future.

The complaint comes in the wake of revelations the Comcast is using Sandvine to actively interfere with and block some BitTorrent, Gnutella, and even Lotus Notes traffic. The ISP is using forged TCP reset packets, which tell both ends of a connection that the other party has reset the connection, to accomplish the task. Comcast admits to managing traffic on its network to ensure a “good Internet experience” for all of its customers. The company argues that its management techniques will occasionally “delay” traffic, but denies that it blocks or degrades traffic, despite evidence to the contrary.
