How priority selective protocols?

[ejml]

Hello Folks,
I have some doubs with Traffic Shapper.

I have run the Traffic Shapper Wizard, in the last step, I have selected the "Other Protocols" and I have left default selected.

Now, I need to give priority some protocols of the qlandef/qwandef. My strategy has been to create a new queue for each protocol to give priority. At this new queue I set a bandwith that I rest of the qlandef/qwandef and I assign priority. So, the sum of the bandwith percentage of the all queues must be 100 %.

On the other hand, I don't understand the UpperLimit and RealTime values If I setup all queues with the percentage bandwith value.
Could somebody help me with some example to use this values together?

Thanks in advance!!
