Traffic classes

This section describes how to configure traffic classes.

Default traffic classes

Kaspersky SD-WAN has default traffic classes for processing and filtering different types of traffic (see the table below). You can create new traffic classes or modify existing ones. Default traffic classes are suitable for most deployment scenarios, and we do not recommend changing them.

Default traffic classes

The default settings presented in the table are described in the instructions for creating and editing traffic classes.

Default traffic classes are suitable for most Kaspersky SD-WAN deployment scenarios, and we do not recommend changing them.

You can create or modify 4 to 8 traffic classes in an SD-WAN instance template, or edit traffic classes in an already deployed SD-WAN instance. If you create traffic classes in an SD-WAN instance template and use that template to deploy an individual instance, the same traffic classes are automatically created in the deployed instance.

To create and edit traffic classes, use the following instructions:

• Creating traffic classes in an SD-WAN instance template.

  In one of the traffic classes you create, you must put control traffic that is used to manage the SD-WAN infrastructure and configure its components, including setting up and managing links, exchanging routing information between devices, and monitoring the status and performance of the network. We recommend to assign control traffic to the highest priority to ensure efficient and reliable functioning of the network.

  To create traffic classes in an SD-WAN instance template:

  1. In the menu, go to the SD-WAN → SD-WAN instance templates subsection.

     A table of SD-WAN instance templates is displayed.

  2. Click the SD-WAN Instance template.

     The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand button .

  3. Select the Traffic classes tab.

     A table of traffic classes is displayed.

  4. Click Edit.
  5. This opens a window; in that window, click + Traffic class to add a traffic class.
  6. In the Name column, enter a name for the traffic class.
  7. In the Queue column, select the number of the queue into which you want to place traffic of the selected class. The higher the value, the higher the priority of the traffic class. You cannot specify the same priority for multiple traffic classes.
  8. In the KOver column, select the overcommitment ratio of the traffic bandwidth, which sets the multiplier by which the bandwidth dedicated to the class can be increased if the total bandwidth is not fully utilized.
  9. If you need to ignore the bandwidth available to the traffic class when calculating the route, select the Exclude when computing path check box. When this check box is selected, you cannot select the KOver ratio for the traffic class. By default, the check box is selected for the last traffic class in the table (Best effort).
  10. In the Default traffic class drop-down list, select the class in which you want to place all traffic that is not included in other classes. By default, the last traffic class in the table is selected (Best effort).
  11. In the Control traffic class drop-down list, select the class in which you want to place control traffic. By default, the first traffic class in the table is selected (Network control).
  12. In the Maximum reserved bandwidth (%) drop-down list, select the percentage of the maximum traffic transfer rate that can be available for one of the created traffic classes. Range of values: 10 to 90. The default setting is 90.
  13. Click Ok.
  14. In the upper part of the settings area, click Save to save the configuration of the SD-WAN instance template.
• Editing traffic classes in an SD-WAN instance template.

  To edit a traffic class in an SD-WAN instance template:

  1. In the menu, go to the SD-WAN → SD-WAN instance templates subsection.

     A table of SD-WAN instance templates is displayed.

  2. Click the SD-WAN Instance template.

     The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand button .

  3. Select the Traffic classes tab.

     A table of traffic classes is displayed.

  4. Click Edit.
  5. This opens a window; in that window, edit the settings that you want to change. For a description of the settings, refer to the instructions for creating traffic classes in an SD-WAN instance template.
  6. Click Ok.
  7. In the upper part of the settings area, click Save to save the configuration of the SD-WAN instance template.
• Editing traffic classes in an already deployed SD-WAN instance.

  To edit traffic classes in an already deployed SD-WAN instance:

  1. In the menu, go to the Infrastructure section.

     The SD-WAN infrastructure management page is displayed. By default, the Network resources tab is selected, which displays the table of SD-WAN Controllers.

  2. Click Management next to the SD-WAN Controller and in the drop-down list, select Configuration menu.

     This opens the SD-WAN Controller configuration menu. By default, you are taken to the Controller nodes section, which displays a table of Controller nodes.

  3. Go to the QoS section.

     The Traffic classes tab, which is selected by default, displays the table of traffic classes.

  4. Click Edit.
  5. This opens a window; in that window, in the Name column, enter a name for the traffic class.
  6. In the Queue column, select the number of the queue into which you want to place traffic of the selected class. The higher the value, the higher the priority of the traffic class. You cannot specify the same priority for multiple traffic classes.
  7. In the KOver column, select the overcommitment ratio of the traffic bandwidth, which sets the multiplier by which the bandwidth dedicated to the class can be increased if the total bandwidth is not fully utilized.
  8. If you need to ignore the bandwidth available to the traffic class when calculating the route, select the Exclude when computing path check box. When this check box is selected, you cannot select the KOver ratio for the traffic class. By default, the check box is selected for the last traffic class in the table (Best effort).
  9. In the Maximum reserved bandwidth (%) drop-down list, select the percentage of the maximum traffic transfer rate that can be available for one of the created traffic classes. Range of values: 10 to 90. The default setting is 90.
  10. Click Ok.
