Comcast Tests a New Bandwidth Throttle
 
From The New York Times, - June 04, 2008

By Saul Hansell

UPDATE | 6/5 7:40 PM: Comcast objected to the first version of this post, which referred to its method for identifying heavy users as a blacklist. After several conversations, including a call with Mitch Bowling, Comcast’s senior vice president and general manger of its Internet service, I’ve rewritten the headline and a bit of the explanation about how the system being tested works.

Some Comcast customers who actively download software and video files may soon find one set of unexplained delays replaced with a different sort of equally cryptic slowdowns.

Comcast is starting to test new approaches to protecting its network from what it describes as congestion caused by a handful of customers who use far far more bandwidth than everyone else. Until now, Comcast has been using devices that interfered with the BitTorrent protocol—the most common method for downloading large files from computers of other users. BitTorrent is often used by people exchanging pornography and illegal copies of movies, but creators of video and software also choose to use BitTorrent as an inexpensive way to distribute their creations.

[This section has been updated] Comcast will test new devices that can identify which Internet customers have been particularly heavy users of bandwidth at any given time. At times when the network in a given neighborhood is congested, it will slow down the Internet connections of those heavy users.

For now, these restrictions are just as mysterious as the secret blocking of BitTorrent. The company won’t say how much usage will be required to have your connection impaired or how much slower it will get.

Mitch Bowling, Comcast’s senior vice president and general manger of its Internet service, said the system will look at the bandwidth used over a period of minutes. That means that someone who downloads a single song won’t go into the slow late, but someone that downloaded a whole movie might, regardless of whether the movie is from iTunes or over BitTorrent.

Most significantly, Comcast won’t even tell its customers if or when they are having their connections throttled. Mr. Bowling said that customers certainly would notice a slowdown.

If users stop downloading for several minutes—he wouldn’t say how long—their connections will be restored to full speed.

Comcast, which was criticized for not being forthright about its restrictions on BitTorrent, has promised to find a new approach that will block heavy users of bandwidth regardless of what content or communication protocol they are using.

It is starting three 30-day tests, each of a different sort of hardware that it might use as the traffic cop for its new restrictions. On Thursday, it will start tests in Chambersburg, Penn., and Warrenton, Va. Later in the summer it will conduct another test in Colorado Springs, Colo.

Charlie Douglas, a Comcast spokesman, said that the test is meant to pick hardware vendor and test different configurations of rules. He points out that the vast majority of users won’t see any changes to their service at all.

“When we roll this out nationally by the end of the year, all those types of questions will be answered,” he said. “We are trying to figure out what do customers want, what techniques need to be in place to create the best user experience.”

Still, how the company can test the effect on its customers without explaining the rules to them and giving them visibility into their own usage remains to be seen. Until that happens, I suspect Comcast will stay on the black list of at least the heaviest users.

If it's the opinion of this forum (AVRevForum.com) that the next wave of video delivery will be downloading video content, where will the bandwidth come from?

Well, I'm glad I don't have ComCast, but I suspect others will follow soon.

This could have a big effect on downloadable HD content as the movies in HD will be huge files.

YEP!!!

This has been one of my problems, or problems I see with downloads is we all need more bandwidth to use them, this new 'issue' will screw the downloaders of all types of things.......

This is highway robbery and nothing more than an excuse to cover their technical limitations in certain areas.

Without explicit notification to it's entire customer base, throttling is no different than a power company rotating blackout (or brownouts) and claiming that this was necessary to ensure the entire grid didn't go down.

But in this case, where no bandwidth restriction was in play before (except due to local traffic requirements), it is now quite clear that - very shortly - bandwidth will become the next great sales pitch and excuse for bad performance.

My website (as an example) is designed specifically to test these bandwidth limits. But then so is any HD download. And I suspect Apple will be at the forefront of solving or legislating bandwidth capability and user expectations as customers of Internet providers!

Haven't I been saying this all along????

Bandwidth will limit downloads, this is just a new way for the companies to keep us from reaping the benefits of technology. In some ways, I understand, bandwidth costs the companies, but if you give me 3Mbps, it shouldn't have a cap on total downloads, it should be the rate you promised and nothing less. If I want to download video 24/7/365, then so what??? The provider guaranteed me a rate, I shouldn't be penalized for use unless the providers go to a per/meg fee......

Did I just really type that? This will be the new cell phone drama!

How many megs do you use???

Face it, if I thought of it, someone in corporate has as well.....
