I'm working on some experiments about my master's degree project. I'm studying some load-balancers (I'm not supposed to cite them here) and the aim is to get for each bandwidth the cpu % usage of a load-balncer x.

I'm using iperf to send traffic to these load-balancers in TCP mode but I can not control the bandwidth of iperf in TCP mode, I can not use UDP mode because the said load-balancers does not handle UDP traffic.

I tried using wondershaper tool and tc command but I'm getting strange results and the results do not make sense.

I would be very glad if someone can point me in the right direction to achieve this. Thank you so much.

Is there any possibility to use Scapy to forge packets of a fixed amount of bandwidth, feel free to correct me if I'm wrong in this point.

Thank you so much.

  • probably iperf is wrong choice. The whole purpose of iperf is to find maximum achievable speed between two hosts. Why can't you use rsync/wget to transfer some data because they have built-in option which allows you to throttle bandwidth. if you have more questions about how to do it, RTFM ;) – Nehal Dattani Jul 13 '15 at 08:44
  • Probably yes. By the way, maybe the right direction is to look for workload/traffic generator for my evaluation @ Nehal Dattani. – user2567806 Jul 13 '15 at 13:33
