As more sophisticated tools for traffic shaping are unveiled, the question soon becomes which service providers aren't throttling customer traffic

Adding itself to the small-but-growing list of ISPs that admit to traffic shaping, Canada-based Bell Sympatico has confessed to using “traffic management” on heavy users “during peak hours.”

“We are now using a Internet Traffic Management to restrict accounts,” wrote an unnamed forum administrator on Bell Sympatico’s support forums. According to the administrator, Bell Sympatico’s traffic shaping affects an unmentioned number of applications and protocols, including BitTorrent, Gnutella, Limewire, Kazaa, eDonkey, eMule and WinMX.

A Bell Sympatico Manager chimed in immediately afterwards, explaining that “there continues to be phenomenal growth of consumer Internet traffic throughout the world” and that “Bell is using Internet Traffic Management to ensure we deliver bandwidth fairly to our customers during peak Internet usage.”

According to the Manager, the bandwidth cap was introduced sometime last year and “doesn't affect the vast majority of [Bell’s] customers.” One concerned user asked if the traffic management will be removed as network capacity increases, to which the administrator replied that he “can’t answer this question,” and noted that it would be decided as the issue arises.

Internet service providers have found themselves under an increasing burden as bandwidth-intensive internet services like online video and file-sharing have proliferated. While the true volume is unknown, many think that 30%-50% of all internet traffic is P2P-related, with a recent survey from traffic-management company Ipoque pushing that number towards an astonishing 90%.

In response to this, many providers have employed a variety of techniques to limit customers who are deemed to be using more than their “fair share,” a tactic that has been the subject of much debate as part of the controversy surrounding “network neutrality.”

While traffic shaping is by far the most common, a few companies have employed more exotic methods: Comcast is thought to impose an invisible 600 GB bandwidth limit on its “unlimited” internet service, and a recent study conducted by the AP found that the ISP impersonates BitTorrent clients for the purposes of interfering with their connections.

If I'm on a shared connection of any type and my bandwidth is being sapped by someone dl'ing stuff on P2P - their banwidth should be throttled. It's a shared connection.

However, if you're on DSL or some other type of connection, you should be able to use your garunteed bandwidth however you want.

You get what you pay for, but I sure as heck don't want my neighbor's kid who leaves on Limewire on 24/7 eating up my bandwidth - odds are he's dl'ing illegal stuff, anyway.

And I'll remind everyone that ISPs aren't stupid. They create and maintain vast infrastructures and employ tons of professionals - they don't arbitrarily throttle bandwidth. There are ways to be reasonably assured whether someone is using P2P or dl'ing a movie from a legit service. And, if all else fails, just change the port the program uses.
