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
