Rogers Cable, Canada’s largest ISP, recently held a press conference to dispel a few myths about how it shapes its bandwidth with regards to people using filesharing networks.

A spokesperson from Rogers said that the ISP does not block filesharing traffic. Rather, it controls the traffic when it is uploading data. Apparently, many people are unaware that when they download material through filesharing networks, they are also uploading data.

Rogers limits the rate at which users can upload material. The idea behind this is that filesharing users then do not then overwhelm all other Internet traffic. Apparently, expanding the network would not solve the problem, so limits must be installed.

Filesharing traffic is designed to overwhelm other traffic. With filesharing traffic expected to triple by the year 2012, ISPs such as Rogers will have their work cut out for them to control the traffic.
