User Guide for the Avaya P580 and P882 Multiservice Switches, v6.1

Chapter 25

The switch always services the queue that has the highest accumulated 
weight. If two queues have the same accumulated weight, the switch first 
services the queue that has the highest priority (0 – 7). 

 lists the default weight increment for each queue. 

For information on how to set up WFQ, see “

” later in this 

chapter.

Suppose that the accumulated weight of all queues is set at their weight 
increments. 

1.  The switch services queue 7 because its accumulated weight is 128.

2.  The accumulated weight of queue 7 is reset to 128, and the accumulated 

weight of all other queues is increased by their weight increment. 

At this point, queue 7 and queue 6 both have an accumulated weight of 
128. 

3.  The switch services queue 7 because it is the higher priority queue. 

4.  The accumulated weight of queue 7 is then reset to 128, and the 

accumulated weight of all other queues is increased by their weight 
increment. 

Now queue 6 has an accumulated weight of 192, and queue 7 has an 
accumulated weight of 128. 

5.  The switch services queue 6 because it has the higher accumulated 

weight.
