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!
