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.
