PRIO example

[Svein Petter Larsen <spla@scandpower.no>]

Hello

I have set up some test for DiffServ and it is working great for link sharing 
with CBQ.
Now I try to use PRIO scheduler insted of CBQ to share the link and make a EF 
class and a BE class. I use the example from iproute.

I do not get the desired result.

How can I use this setup and managed to get enough bandwith to my EF class?

The PRIO scheduler is not able to make classes. What is then the difference 
of the children I make for EF and BE compared to when I make classes for this 
with CBQ?



Is PRIO useful?

Has anybody out there some other examples that you have tested and worked 
well?

Best regards
Petter Larsen
