= Step 4: Execute Experiment =
To run the experiment we will use two terminals to login to the ''"right-client"'' and the ''"left-client"'' VMs and one browser to connect to the ''"server"'' VM to review results.
'''1.''' Start 2 terminal windows and use the `readyToLogin` script to determine the login information:
__Window 1:__
{{{
$ readyToLogin -a rightAggr MySlice
....
$ ssh -i right-client....
...
}}}
__Window_2:__
{{{
$ readyToLogin -a leftAggr MySlice
...
$ ssh -i left-client....
...
}}}
'''2.''' Start a browser and navigate to the ''"server's"''s hostname from readyToLogin output in previous step. For this example experiment the hostname allocated is pcvm1-15.instageni.stanford.edu:

'''3.''' In the first terminal logged in to ''"right-client"'', install iperf and send traffic to the server over the ''stitched'' path by executing the 2 commands exactly as shown:
{{{
right-client$ /usr/bin/iperf -c 192.168.1.2 -t 30 -P 5
}}}
'''4.''' In the second terminal connected to ''"left-client"''. install iperf and send traffic to the server over the ''local'' link by executing the 2 commands exactly as shown:
{{{
left-client$ /usr/bin/iperf -c 10.10.1.2 -t 30 -P 5
}}}
'''5.''' Now back in the browser: Refresh the web page and you should see the results from the iperf server.
''Note: '' The interface capacity for all links was set to '' '''20 Mbits/sec''' '' in the RSpec used for this tutorial.

The experiment is now completed; time to release resources!
