Citrix SD-WAN Center 11.4

Class report

March 12, 2021

Contributed by:

The virtual services can be assigned to particular QoS classes, and different bandwidth restraints can be applied to different classes. A class can be one of three basic types:

Real-time classes: Serve traffic flows that demand prompt service up to a certain bandwidth limit. Low latency is preferred over aggregate throughput.
Interactive classes: Serve traffic flows that are sensitive to loss and latency. Interactive classes have lower priority than real-time but have absolute priority over bulk traffic.
Bulk classes: Serve traffic flows that require high bandwidth and are sensitive to loss. Bulk classes have the lowest priority.

Specifying different bandwidth requirements for different classes enables the virtual path scheduler to arbitrate competing bandwidth requests from multiple classes of the same type. The scheduler uses the Hierarchical Fair Service Curve (HFSC) algorithm to achieve fairness among the classes.

For more information about customizing classes, see Customizing Classes.

To view class statistics:

In Citrix SD-WAN Center, navigate to Reports > Classes, and in the timeline control select a time period.

You can select and view reports of a particular period by using the timeline controls. For more information, see, Timeline controls.

Note

You can view the Class data of last 30 days. Any data beyond this period is automatically removed from the SD-WAN Center collector and the respective regional collectors.

You can also create, save and open report views. For more information, see, Manage views.
