+===== -. [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.
+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
