[LARTC] isolated works fine for me

i've isolated a band of 5k for one of my friends in the network so he can play counter-strike .. if i don't use the isolated parameter he will have a bad ping since his class will borrow to another classes ..

I tried it a few times (you can find the test results somewhere on 
www.docum.org).  Using the isolated parameter gave me strange testing 
results.
Can you post your script so I can take a look at it ?

I tried to reserve bandwidth for cs, too, but it didn't really work. So if
you work something out I would apreciate it if you post it here ;)

thanks and best regards

Reserving bandwidth for something is not so difficult.  If you have a 100kbps 
link and you want a minimum of 10kbps for cs, you have to create 2 class : 

  100
  /  \
10  90

100 : rate = ceil = 100kbps
10 : rate = 10kbps, celi = 100kbps
90 : rate = 90kbps, ceil = 100kbps

The 10kbps class will always get at least 10kbps.  If it's a low rate class, 
you can even limit the 90kbps to 90kbps.  So the remaining 10kbps is always 
there for the 10kbps class.

I already shape my traffic with htb and it works pretty well. But I think
I ran into the same problem as Daniel. If there is lots of other traffic
the class where all packtes of counter-strike are in has still bandwidth
available, but I'm getting ping times around 400ms (40ms if there is no
other traffic). I'm not sure if I'm missing to mark some packets of
counter-strike here or if "htb is to slow" or something else :o Therefore
I asked to get the solution if you work something out - perhaps I can fix
my scripts then ;)

best regards
