Comcast is testing new technologies that would slow the transmission of Internet files for its biggest users by as much as 20 minutes during times of heavy network congestion. But the nation's largest cable provider has promised not to target specific content, such as video files that compete with its cable television business.
The tests come as the Federal Communications Commission yesterday released an order that forces Comcast to stop its earlier efforts to block transmission of certain Internet files, a ruling that public interest groups hailed, saying it would prevent network operators from acting as gatekeepers of the Web.
Comcast didn't respond to details of the FCC's order, but spokeswoman Sena Fitzmaurice said, "We are examining the order and will evaluate our next step."
Comcast began testing its system of slowing certain traffic in March and has expanded the tests to Warrenton; Chambersburg, Pa.; Colorado Springs; Lakeview, Fla.; and East Orange, Fla. It will adopt the new network management technology by the end of the year, the company said.
"We are in a trial, and final results of that are yet unknown, which is why we do trials," said Mitch Bowling, Comcast's general manager of online services. "The important point is that the intent of network management has and continues to be to provide a great experience for our customers."
In yesterday's order, the FCC concluded that Comcast's earlier management of Internet traffic was discriminatory and "inconsistent with the concept of an open and accessible Internet."
After public hearings in Cambridge, Mass., and Silicon Valley and several months of investigations, the agency said Comcast had looked into the packets of Internet files being transferred between users and deliberately blocked certain files.
The commission said Comcast had an "anticompetitive motive" because it delayed and blocked peer-to-peer files through applications such as BitTorrent. Such files often are high-quality video that might otherwise be watched and paid for on cable television.
