11) QoS (Quality of Service) Parameters
The Quality of Service (QoS) feature is based on 802.16 standard and defines the classes, service flows (SFCs),
and packet identification rules (PIRs) for specific types of traffic. QoS main priority is to guarantee a reliable and
adequate transmission quality for all traffic types under conditions of high congestion and bandwidth over-
subscription (for a complete discussion on QoS see “Quality of Service (QoS)”
on page 28).
There are already several pre-defined QoS classes, SFCs and PIRs available that you may choose from which
cover the most common types of traffic. If you want to configure something else, you start building the hierarchy
of a QoS class by defining PIRs; then you associate some of those PIRs to specific Service Flow classes (SFCs);
you assign priorities to each PIR within each SFC; and finally you define the QoS class by associating relevant
SFCs to each QoS class.
QoS PIR Configuration
Click the Configure button, the QoS tab and the QoS PIR Table sub-tab. The 17 predefined PIRs are shown.
To view/edit the parameters of each PIR click on its Details button. You may enable, disable or delete this PIR
entry by clicking on the Status drop-down box and then clicking OK.
