 +===== -. [CO2] Implementing the Applications and Tools ===== 
 +In order to describe and analyze the basic steps for installing and using the tools and client/server applications, we need to look carefully to these 4 applications: iperf, flent, VLC, HTTP. 
 + 
 +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.
