How to Customize Classes
Jan 05, 2017
The SD-WAN configuration provides a default set of application-classification, rule-filtering, and class-assignment settings
that can be applied to any virtual path service in the SD-WAN environment. You can also customize these settings.
Using classes, you can classify a specific type of traffic on the virtual path, and then you can apply rules to handle this
traffic. Traffic is assigned to a specific class, as defined in the rule.
For more information about creating rules, see How to Create Rules .
The SD-WAN system provides 17 classes (0-16). Classes 0-3 are predefined for Citrix HDX QoS prioritization. To use this
feature, enable the following options:
WAN Opt imizat ion WAN Opt imizat ion, available under Opt imizat ion Opt imizat ion > Feat ures Feat ures.
HDX QoS Priorit ies HDX QoS Priorit ies, available under Opt imizat ion Opt imizat ion > Feat ures Feat ures.
ICA Service Class ICA Service Class, available under Opt imizat ion Opt imizat ion > Service Classes Service Classes.
These classes are used to classify HDX traffic with different ICA priority tags. You can edit the class types and their
assigned bandwidth sharing to obtain the optimal quality of service, but you cannot edit the names of the classes.
Classes 10-16 are predefined and are associated with Realtime, Interactive, and Bulk class types. Each type can be
configured further to optimize quality of service for its type of traffic. Classes 4-9 can be used to specify user defined
classes. Classes are of one of the following three types:
Realtime: Used for low latency, low bandwidth, time-sensitive traffic. Real-time applications are time sensitive but don't
really need high bandwidth (for example voice over IP). Real-time applications are very sensitive to latency and jitter, but
can tolerate some loss.
Interactive: Used for interactive traffic with low to medium latency requirements and low to medium bandwidth
requirements. Interactive applications involve human input in the form of mouse clicks or cursor moves. The interaction is
typically between a client and a server. The communication might not need high bandwidth but is sensitive to loss and
latency. However, server to client does need high bandwidth to transfer graphical information, which might not be
sensitive to loss.
Bulk: Used for high bandwidth traffic that can tolerate high latency. Applications that handle file transfer and need high
bandwidth are categorized as bulk class. These applications involve very little human interference and are mostly handled
by the systems themselves.
