16.11.3.4 Traffic Shaping
The following figure illustrates how the classified traffic is shaped by the traffic shaper.
Per classified traffic node, traffic shaping can be performed.
Classification rules must always be attached to the most specific shaping node in a
shaping tree.
One shaping node cannot have both a child node and a rule attached to it.
(For example: Node1 with a Rule 1 and one child node Node11 is not possible and is
prohibited by the GUI.)
Traffic shaping makes it possible to restrict the maximum given PIR (Peak Information Rate) in a
flexible way. Next to the PIR a CIR (Committed Information Rate) is used for the distribution of the
total available rate.
The traffic shaping software also allows the distribution of the available rate among services in order
to for example higher prioritize time critical VoIP traffic and to throttle certain downloads.
As shown in the next figure, a Parent Node can contain more sub nodes. These sub nodes inherit
the settings of the previous node and are then again divided in a PIR and CIR.
