+Similarly, the configuration of the GL-iNET router below shows the following:

+===== -. [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:
-</file>
+- To activate iperf3:
-===== Extracts =====
+	    * On the server side: iperf3 -s
-#On TPlink router
+	    * On the client side: iperf3 -c 192.168.200.192
-<file /etc/config/dhcp>

-        option domainneeded '1'
-        option boguspriv '1'
-        option filterwin2k '0'
-        option localise_queries '1'
-        option rebind_protection '1'
-        option rebind_localhost '1'
-        option local '/lan/'
-        option domain 'lan'
-        option expandhosts '1'
-        option nonegcache '0'
-        option authoritative '1'
-        option readethers '1'
-        option leasefile '/tmp/dhcp.leases'
-        option resolvfile '/tmp/resolv.conf.auto'
-        option localservice '1'
-config dhcp 'lan'
+- To visualize UDP trafic with a specific bandwidth:
-        option interface 'lan'
+	    * On the client side: iperf3 -c 192.168.200.192 -u -b 2M
-        option start '100'
+Here we set the bandwidth with UDP to 2Mbit/s.
-        option limit '150'
+Note that by default ,UDP sets the bandwidth to 1Mbit/s
-        option leasetime '12h'
-        option dhcpv6 'server'
-        option ra 'server'
-config dhcp 'wan'
+- To extend the transmission time(second) as well as the number packets sent:
-        option interface 'wan'
+	    * On the Client side: iperf3 -c 192.168.200.192 -t 15
-        option ignore '1'
+Note that  by default, iperf3 sets the time to 10 seconds
-config odhcpd 'odhcpd'
+- To reverse mode(server sends, client receives):
-        option maindhcp '0'
+	    * On the Client side: iper3 -c 192.168.200.192 -R
-        option leasefile '/tmp/hosts/odhcpd'
-        option leasetrigger '/usr/sbin/odhcpd-update'
+- 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
