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.
