AT&T Might Consider Usage-Based Access Pricing

AT&T might consider a usage-based approach to pricing broadband access, a solution to the problem of supporting very-heavy bandwidth users without resorting to blocking or traffic shaping, says CTO John Donovan. He says "one percent of the company's customers account for 20 percent of the network usage; the top five percent account for 40 percent of the usage."

In other remarks, Donovan says "traffic on our backbone is growing 60 percent per year."

"I don't view any of our customers, under any circumstances, as pirates -- I view them as users," Donovan said. "A heavy user is not a bad customer."

And users aren't dumb. If they have incentives to use P2P at off-peak hours, they will. BitTorrent use on the AT&T network peaks around 4 a.m., when other traffic is at an ebb, he says.

Peer to peer traffic represents about 20 percent of total network traffic, he adds.
