Caught in the throttle

The Ottawa Business Journal is reporting that Canadian ISP’s are “throttling” or “traffic shaping” in order to prioritize traffic. The primary target is actually to degrade performance for bittorrent traffic.

In Canada, Rogers and Shaw in Vancouver have responded by reducing the high speed of users downloading and uploading (or seeding) torrents. Rogers admitted to what it called “prioritizing” “real-time use” such as surfing and e-mail transfers ahead of large file transfers in a December 2005 article in the Globe and Mail.

In response users have begun to encrypt their bittorrent traffic so that it is not easily distinguishable from other traffic so Rogers has reportedly begun “to simply degrade all encrypted traffic, legal or not.”
