Hi Stef, I also found there is some accuracy issue in CBQ. The performance on my machine, the output BW will be cut off at around 20 Mbps even if the class bounded limit is larger. However, as the "bounded" is taken away for the class, the output BW can be up to PHY limit--100Mbps. In other words, in my system, "bounded" can work only if the limit is below 20 Mbps. Besides, "isolated" doesn't seem to work as its original design. About your testing results, I am a little confused in the unit you use (bit or Byte). And if you try shorter packet length, the accuracy will be improved. B.R.

Hi there, I have done a lot of testing and I have a few questions about CBQ. You can split the traffic in diffent classes and it works great. But to do this, I have to add as the first class a bounded class with rate = available link-bandwidth. I have tried different rates but CBQ isn't very accurate. I added the testing results at the bottom of the posting (or go to http://users.belgacom.net/staf/) As you can see there are some very strange results (notice the change in throughput when I changed the rate 1kbps around 71475kbps and 135556kbps). I also noticed that the accuracy of splitting the traffic in different classes is very good unless you want to give a class < 25% of the bandwidth. I'm wondering if someone encountered the same problem and/or if it is a problem with tc or the kernel itself. -- Staf More QOS info : http://users.belgacom.net/staf/ RESULTS : RATE_TOT RESULT 1 kbps 1.05 KB/s 2 kbps 2.10 KB/s 3 kbps 3.04 KB/s 4 kbps 4.17 KB/s 5 kbps 5.02 KB/s 10 kbps 9.91 KB/s 15 kbps 14.7 KB/s 20 kbps 18.8 KB/s 30 kbps 29.2 KB/s 40 kbps 36.5 KB/s 50 kbps 49.2 KB/s 60 kbps 49.4 KB/s 65 kbps 49.3 KB/s 67 kbps 49.3 KB/s 68 kbps 49.3 KB/s 69 kbps 49.3 KB/s 71475 bps 51.1 KB/s 71476 bps 69.7 KB/s 70 kbps 69.9 KB/s 80 kbps 69.9 KB/s 90 kbps 70.3 KB/s 100 kbps 75.4 KB/s 130 kbps 75.7 KB/s 135556 bps 78.7 KB/s 135557 bps 139 KB/s 140 kbps 140 KB/s 150 kbps 140 KB/s 200 kbps 140 KB/s 300 kbps 140 KB/s 500 kbps 140 KB/s 1000 kbps 140 KB/s 1310719bps 146 KB/s 1310720bps 940 KB/s 2000 kbps 945 KB/s --__--__-- Message: 2 Date: Tue, 24 Apr 2001 02:14:34 -0400 From: johan@xxxxxxxxxxxxxx To: lartc@xxxxxxxxxxxxxxx Subject: [LARTC] need suggest for tc..fw Dear all...
