[LARTC] Bandwidth Problems

[LARTC] Bandwidth Problems

[Rendel, Thorsten]

hi,
i use the tc tool to shape traffic. in my testbed i have 3 pc´s. 2 of them act as server and client for the iperf traffic generator programm. the 3. pc is my traffic router. 
i used in my tests the tbf, cbq and htb qdisc. i wanted to shape traffic form 50 Mbit/s to 5 Mbit/s. i used a small packet size in my tests (64byte). the result was horrible. None of this qidsc couldn´t shape may traffic to its allocate rate.
Does anybody know a solution for this problem?
Thanx in advance.
Thorsten

I have the same setup, but I use ttcp als traffic generator with default 
packet size.  Cbq/htb/tbf works with no problem.  You can find the results 
and scripts on www.docum.org
