| Actually, according to the article, I think it is possible to do so. From the article:
it charges people $10 more each month if they want to make sure a third-party Internet telephone service, from a service provider such as Vonage or Primus, works properly over Shaw's high-speed service. "Without this service customers may encounter quality of service issues with their voice over Internet service," the company states on its website. As one industry source told me, "It's a sneaky way of saying if you don't get this your service will suck." Suddenly, high-speed customers with "regular" service find themselves as second-class cybercitizens. To accomplish this, Shaw uses technology from Merrimack, N.H.-based Ellacoya Networks Inc., among a handful of companies including Cisco-owned P-Cube Inc. of Sunnyvale, Calif., and Waterloo-based Sandvine Inc. that have perfected the art of what's known as "deep packet inspection." Basically, the technology can analyze all traffic on a high-speed network, identify what it is, and then "mark" it that is, assign it a level of priority chosen by the network operator. It means Shaw knows which subscriber on its network is using a Primus VoIP service, or Kazaa for downloading music, or Bit Torrent for downloading movies. In fact, it inspects even deeper. Not only does the technology know you're using Kazaa, for example, but it knows the specific songs you have chosen to download, which itself has privacy implications depending on how a network operator uses it. This says to me that the cable provider is examining the packets, recognizing that they are being used to carry VoIP traffic (specifically, a 3rd party's VoIP traffic) and assigning them lower priority. If the user were to use the cable company's own VoIP solution, then the traffic would be given normal priority.
The later part of the statement seems to indicate that the company can identify specific properties of the request (which song is being downloaded, for example). It's not too far of a jump to go from "which song" to "which URL". (If anything, it's probably easier to identify.)
Of course, the rest of my post was purely hypothetical in nature. I didn't mean to imply that any provider was taking such action. Merely that such action is theoretically possible given this technology. -- -Jason Levine My Gallery | Jason's Toolbox | PCQandA.com | URateit.com |

| reply to Drex_CS said by Drex_CS :said by John_W :Talk about being anti-competitive. what's anti=competitive? the guy above you posted a "hypathetical" situation in which a cable company "could" slow down connection to a website... To bad that it's not possible to do. It's fairly trivial to block or slow connections to specific sites. There are also a number of ways to do it (at different layers of the IP stack).
