[LARTC] CBQ bounded & isolated

[Amit Kucheria <amitk@ittc.ku.edu>]

I am trying to reproduce Stef's CBQ tests from www.docum.org

My setup is very simple :

  testbed43 --------> testbed44 -------> testbed45
   (src)               (CBQ)              (sink)
 192.168.10.2    in:  192.168.10.254     192.168.100.2
                 out: 192.168.100.254   

I have 2 isolated classes (2:2 and 2:3) which need to share the 
bandwidth. I have only one traffic source at the moment whose traffic is 
sent into 2:2, but *doesnot* get limited to the rate specified in 2:2.

Any clues would be welcome.

TIA.

ciao,
Amit
p.s. Stef - You 'tests' page is down.
