don't understand the below exactly .

could you explain the exact meaning according to the realworld?

To determine the bandwidth allocation for each queue, divide the byte count for the flow by the total byte count for all flows. For example, if you have one flow at each precedence level, each flow will get

precedence + 1 parts of the link:

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36

Thus, precedence 0 traffic will get 1/36 of the bandwidth, precedence 1 traffic will get 2/36, and precedence 7 traffic will get 8/36.

However, if you have 18 precedence 1 flows and one of each of the rest, the total is now:

1 + 2(18) + 3 + 4 + 5 + 6 + 7 + 8 = 70

Precedence 0 traffic will get 1/70, each of the precedence 1 flows will get 2/70, and so on. As flows are added or ended, the actual allocated bandwidth will continuously change.

This really is tough to understand. May be some QoS documents could help you to understand it better. http://www.cisco.com/pcgi-bin/Support/browse/index.pl?i=Technologies&f=773
