Notes:
1. Queue with higher class number has higher priority than queue with lower class number.
That means Class 3 > Class 2 > Class 1 > Class 0 by default.
2. In weighted ratio policies, a weighted fairness round robin service is guaranteed normally.
However, when excess bandwidth exists higher class queue will take advantage on band-
width allocation.
