Hi, All
I want to use the QoS feature of OpenvSwitch to control the bandwidth based on the vlan id(scene 1) or port id(scene 2). So I deployed it as the pdf file show,and configured the flows, the qos rules, and used iperf tool to test it. But the result is disappointment. In scene 1: The bandwidth is not 800M. [root@host1 ~]# iperf -c 10.10.12.4 -i 1 -t 100 -P 20 |grep SUM [SUM] 0.0- 1.0 sec 53.2 MBytes 446 Mbits/sec [SUM] 1.0- 2.0 sec 51.0 MBytes 428 Mbits/sec [SUM] 2.0- 3.0 sec 54.3 MBytes 455 Mbits/sec [SUM] 3.0- 4.0 sec 50.9 MBytes 427 Mbits/sec [SUM] 6.0- 7.0 sec 50.5 MBytes 424 Mbits/sec [SUM] 7.0- 8.0 sec 51.3 MBytes 430 Mbits/sec [SUM] 8.0- 9.0 sec 50.1 MBytes 420 Mbits/sec [SUM] 9.0-10.0 sec 52.0 MBytes 436 Mbits/sec [SUM] 10.0-11.0 sec 47.2 MBytes 396 Mbits/sec [SUM] 11.0-12.0 sec 52.9 MBytes 444 Mbits/sec [SUM] 12.0-13.0 sec 47.8 MBytes 401 Mbits/sec [SUM] 13.0-14.0 sec 51.1 MBytes 429 Mbits/sec [SUM] 14.0-15.0 sec 47.4 MBytes 398 Mbits/sec [SUM] 15.0-16.0 sec 61.7 MBytes 518 Mbits/sec In scene 2: If only “iperf -c 10.10.12.4 -N 5”, the bandwidth is 940M. But after “iperf -c 192.168.4.3 -N 50”, the bandwidth for 10.10.12.4 down to 150M.
