Example

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.
