A particular application in the network can be defined by the group of rules that is applied to it. The SD-WAN configuration editor provides a default list of rule groups. You can also create custom rule groups and tag individual rules to the application.
For more information about rules, see. How to Create Rules.
The mean opinion score (MOS) is a numerical measure of the quality of the experience that an application delivers to end users. It is primarily used for VoIP applications. In SD-WAN, MOS is also used to assess the quality of non-VoIP applications by judging the traffic as if it were a VoIP call.
SD-WAN Center calculates and displays the MOS for existing traffic that passes through the virtual path. For more information about viewing MOS in SD-WAN Center, see How to View MOS for Applications.
To add a custom rule group:
1. In the Configuration Editor, navigate to Global > Rule Groups.
The default list of rule groups appears.
2. Click the add (+) icon.
3. Enter the application name.
4. Click the pencil icon and select Estimate MOS.
