[LARTC] prio + htb?

[LARTC] prio + htb?

[Esteban]

Stef, Lartc people,

Hello, im using the above script for my network It works okay, the htb
assigns the BW i want for outgoing traffic. But now, im looking foward
giving priority to the packets on the first class under the second, i mean
the first class packets leave the interface first than the second class. How
do i apply that without loosing my conf?

Well, thank you all for the help!
Esteban

Using different prio's can be tricky.  It can speed up some packets, but at 
the same moment, creating extra delays for the same packets if you send too 
much of them.
At the same time, you have to be carefully with the different rates for the 
child classes.  Make sure the sum is not more then the parent rate.  
Otherwise it can be difficult to find out what wil happen.
