No, I really don't think so. The link itself is a 100%-CIR SDSL (for
LANof 300+ machines). I've
set up ceil(up and down) to ~95% of real bandwidth.
It seems that classes exceed maximum rates (ceils) defined for them.
For example : p2p class has ceil of 2.5 mbits
When p2p traffic is not allowed to pass through bandwidth usage varies
around 30%.
Afrer allowing p2p to pass bandwidth usage quickly rises to nearly 100%.
Is it possible to somehow isolate a class (as in cbq?) ?. In the
archives I've
found something like this (let's say): '[...] rate 2500kbit ceil
2500kbit'. This should
produce something like isolated class , but for me it simply doesn't work.
I'd be very grateful for any suggestions / ideas ...
Ratel
