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.

Not exactly the same situations there, but you are right that we shouldn't really take either situation.

The problem with p2p, at least according to the companies, is that when someone is using p2p the 'separate connections' number skyrockets and their servers have a hard time handling that, according to someone who works for Comcast whose blog I was reading yesterday.

If that is the case...... then just adding 'bandwidth' and stuff won't help.... they actually need to re-do the whole system, in order to make them able to handle those massive numbers of connections.

Cable internet works on a shared connection - don't expect dedicated bandwidth from it. Do you really think these ISPs are throttling back P2P traffic at random or arbitrary points throughout the day? More than likely, they're doing it as-needed - like if you're dl'ing season 2 of Heroes, and your neighbor is trying to grab an album of his grandson off of snapfish.
