Tangling over Net traffic cops

Last week, the company caused another stir when it paid passers-by to fill seats at a contentious Federal Communications Commission hearing where critics turned out in droves to complain about surreptitious tampering with their online activities.

At the heart of the matter is what's known in tech circles as "net neutrality," the notion that all content is created equal and that network operators have no right to pick and choose what gets to traverse their lines.

Internet service providers like cable and phone companies argue that they're being overwhelmed by a relative few bandwidth hogs who are spoiling things for other users, and that they have to play traffic cop to keep the information superhighway running smoothly.

Net neutrality proponents counter that the solution is for telcos to upgrade their networks, not pick and choose who gets a green light online and who doesn't.

"We're at a critical juncture," said Craig Aaron, spokesman for Free Press, an advocacy group that focuses on Internet issues. "We're either going to have an open Internet like we've had in the past, or a closed Internet where companies like Comcast get to decide what you can do."

Comcast, which operates primarily in Northern California, is the only major Internet service provider caught actively interfering with customers' file sharing without providing warning. But most others reserve the right to do the same.

For example, the "acceptable use policy" for Time Warner's broadband Internet service says the company "may use various tools and techniques in order to efficiently manage its networks."

A Time Warner spokeswoman said the company is "not doing what Comcast is doing" but could do so at any time.

"What Comcast did is just plain wrong," said Doug Walker, chief exec of San Francisco's BitTorrent, the leading provider of technology for sharing heavy-duty content over the Net. "They were blocking Internet traffic and not letting people know that they were doing it."

Comcast's shenanigans came to light early last year when a handful of tech-savvy customers started noticing their online file-sharing activities were continually being interrupted.
