+ | ===== -. [CO2] Implementing the Applications and Tools ===== | ||
+ | In order to describe and analyze | ||
+ | |||
+ | Let's start with the application iperf: | ||
+ | |||
+ | - To activate iperf3: | ||
+ | * On the server side: iperf3 -s | ||
+ | * On the client side: iperf3 -c 192.168.200.192 | ||
+ | |||
+ | - To visualize UDP trafic with a specific bandwidth: | ||
+ | * On the client side: iperf3 -c 192.168.200.192 -u -b 2M | ||
+ | Here we set the bandwidth with UDP to 2Mbit/s. | ||
+ | Note that by default ,UDP sets the bandwidth to 1Mbit/s | ||
+ | |||
+ | - To extend the transmission time(second) as well as the number packets sent: | ||
+ | * On the Client side: iperf3 -c 192.168.200.192 -t 15 | ||
+ | Note that by default, iperf3 sets the time to 10 seconds | ||
+ | |||
+ | - To reverse mode(server sends, client receives): | ||
+ | * On the Client side: iper3 -c 192.168.200.192 -R | ||
+ | |||
+ | - To end multiple flows: | ||
+ | * On the Client side: iper3 -c 192.168.200.192 -P 2 -t 60 | ||
+ | |||
+ | Here we are sending 2 flows in 1 min(60 seconds) | ||
+ | Note that we need to extend more the tx time in order to have similar throughput for the 2 flows so that we don't consider it as a fairness issue. | ||
+ | |||
+ | Let's analyze flent application: | ||
+ | * On the Server side: netserver & | ||
+ | -To visualize one TCP stream: | ||
+ | * On the Client side: flent tcp_upload -p totals -l 60 -H 192.168.200.192 -t title2 -o test2.png | ||
+ | -To visualize 12 TCP streams: | ||
+ | * On the Client side: flent tcp_12up -p totals -l 60 -H 192.168.200.192 -t title3 -o test3.png | ||
