Traffic shaper

This grid lists the traffic shapers that may be assigned to network interfaces to which QoS has been applied.

DEFINITION
Traffic shaping refers to how the volume of traffic is controlled on a computer network in order to optimize or guarantee performance, lower latency or increase usable bandwidth by delaying packets that meet certain criteria. More specifically, traffic shaping refers to any action on network traffic that imposes an additional delay on these packets so that they comply with a predetermined constraint (contractual or related to a certain type of traffic).

Possible operations

You can Add or Delete traffic shapers. If you wish to delete a traffic shaper used on a network interface, a warning message will ask you to change the QoS configuration before deleting it.

The traffic shapers displayed can also be filtered by entering a character string in the filter field.

Grid

Name Name given to the traffic shaper.
Outgoing bandwidth

Indicate the outgoing bandwidth reserved for the traffic shaper.

When a traffic shaper is defined for the interface linked to the Internet access router, you are advised to set this value to 95% of the maximum bandwidth on the Internet link.

Unit

Select the outgoing bandwidth unit assigned to the traffic shaper:

  • Kbit/s,
  • Mbit/s,
  • Gbit/s.
Incoming bandwidth

Indicate the incoming bandwidth reserved for the traffic shaper.

When a traffic shaper is defined for the interface linked to the Internet access router, you are advised to set this value to 95% of the maximum bandwidth on the Internet link.

Unit

Select the incoming bandwidth unit assigned to the traffic shaper:

  • Kbit/s,
  • Mbit/s,
  • Gbit/s.

Interfaces with QoS

In this grid, you can define the interfaces to which QoS is applied, as well as traffic shaping, queues or queues for TCP ACK traffic to use for each of these interfaces.

Possible operations

You can Add or Delete Interface/Traffic shaper/Queue/ACK queue associations.

Grid

Interface Select the interface to which you want to apply QoS.
Traffic shaper

Select one of the traffic shapers defined on the firewall.

Default queue

Select one of the queues defined on the firewall.
If you do not wish to assign any particular queue, select Bypass.

Default ACK queue

Select one of the queues defined on the firewall.
If you do not wish to assign any particular ACK queue, select Bypass.
