What is traffic management?
Every 15 minutes, a system checks the usage rate of each upstream channel. If the usage rate exceeds the threshold in which congestion occurs, the system locates service modems with a speed of 20 Mbps or more from the channel through which an important quantity of data is uploaded. The upload of these modems is then placed at a low priority. Depending on the severity and duration of the congestion, their upstream speeds may then be slowed.
If the modem reduces its upload or if the channel usage is reduced to an adequate level to avoid congestion, the upload is restored to a normal priority.
Why traffic management?
Videotron’s traffic management does not target any particular type of traffic or specific applications or protocols, such as peer-to-peer file sharing. Only the transmission of data upstream (upload) of services with a high transmission speed of 20 Mbps or more is subject to traffic management in order to prevent a certain number of modems from lowering the level of service quality.
No traffic management is applied downstream (download).
Good to know
Even when they no longer have priority, the service modems with a sending speed of 20 Mbps or more can use all the upstream bandwidth unused by the other modems, up to their rated speed.
The measures described above are applied at all times.
