GENI Inter-Aggregate Stitching Tutorial
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.... ...
For example in this tutorial we use:
$ readyToLogin -a stanford-ig MySlice ... left-client's geni_status is: ready (am_status:ready) User lnevers logs in to left-client using: ssh -p 31802 -i /Users/lnevers/.ssh/geni_cert_portal_key lnevers@pc1.instageni.stanford.edu server's geni_status is: ready (am_status:ready) User lnevers logs in to server using: ssh -i /Users/lnevers/.ssh/geni_cert_portal_key lnevers@pcvm1-15.instageni.stanford.edu $ ssh -p 31802 -i /Users/lnevers/.ssh/geni_cert_portal_key lnevers@pc1.instageni.stanford.edu Last login: Thu Mar 13 07:16:54 2014 from 128.89.73.116 [lnevers@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!
