I have tested meter action in OpenFLow. I have drawn following conclusions:
- TCP - Conclusion: meter works fine for low rate-limiting values (till ~100Mbps). However, for higher values, the expected bandwidth is relatively very low. - *UDP:* - Conclusion: meter action not supported for UDP - Please let me know Why I am seeing this behavior with TCP traffic? Is it expected? If so, How can I get expected bandwidth equal to the rate I specify in OpenFlow meter? Also, does meter action work for UDP traffic? - Testing metering feature - L:leaf - H:host - NA: not applicable Transport Protocol Server Client Avrg RTT ms TCPWin (KB) Actual Bandwidth (Mbps) Rate Limiting (Mbps) Time duration(s) TCP H1 L1 0.243 416 855 None (1Gbps link) 10 TCP H1 L1 0.243 416 3.25 3 10 TCP H1 L1 0.243 416 29.7 30 10 TCP H1 L1 0.243 416 57.5 60 10 TCP H1 L1 0.243 416 92.2 100 10 TCP H1 L1 0.243 416 131 150 10 TCP H1 L1 0.243 416 164 200 10 TCP H1 L1 0.243 416 230 300 10 TCP H1 L1 0.243 416 282 400 10 TCP H1 L1 0.243 416 331 500 10 TCP H1 L1 0.243 416 361 600 10 TCP H1 L1 0.243 416 398 700 10 TCP H1 L1 0.243 416 436 800 10 TCP H1 L1 0.243 416 489 1000 (1Gbps) 10 TCP H1 L1 0.243 416 852 5000 (5Gbps) 10 TCP H1 L1 0.243 416 868 10000 (10 Gbps) 10 UDP H1 L1 .243 NA L1->H1: 815 H1->L1 : 18.3 100 10 Thank you.
