11.2.2 Configuring Shaping Classes
The bandwidth of a device can be divided to reserve constant portions of bandwidth to
user-defined
traffic types. Such a portion is known as a
Shaping Class . When not used by
its user-defined
traffic type or owner (for example, VoIP), the class is then available to all
other traffic. However when needed, the entire class is reserved solely for its owner.
Moreover, you can limit the maximum bandwidth that a class can use even if the entire
bandwidth is available.
When a shaping class is defined for a specific traffic type, two shaping classes are created.
The second class is the 'Default Class', responsible for all the packets that do not match
the defined shaping class or any other classes that may be defined on the device. This can
be viewed in the Class Statistics screen.
