OpenFlow-Based Vertical Handoff over WiFi and WiMAX in the Orbit Testbed
5. Teardown Experiment
- Stop ping by issuing a SIGINT via ctrl+c.
- Execute the /root/gec20_teardown.sh script to kill Floodlight and OVS.
6. Archive Experiment
- Optionally, if you would like to save your image for future use and perhaps modify or expand upon this experiment:
- Prepare the Orbit image for archival and run prepare.sh in the /root directory. This script will save the configuration of your image and shutdown the node (i.e. your SSH pipe will be broken).
- Save the image from the Orbit node the client was running on by executing omf save -n <your_client's_node_ID> where <your_client's_node_ID> is the full name of the node you wish to save. For example, node10-10.grid.orbit-lab.org. This process might take some time, but note the name of your image, which will be something to the effect of <your_user_name>-node-<your_client's_node_ID>-<the_current_date_and_time>.ndz where <your_user_name> is your Orbit Lab user name, <your_client's_node_ID> is the full name of the node you wish to save, and <the_current_date_and_time> is the date and time of the saved image to the nearest second. Write this image name down or save it in a safe place. You will be able to load and boot it at a later date if you have a reservation in Orbit.
- If you skipped step 1, exit your SSH sessions by typing exit in all open SSH connections to the client.
- Shutdown any nodes you were using in Orbit by running omf tell -a offh -t <your_client's_node_ID>, where <your_client's_node_ID> is the full name of the node you wish to shut down. If you have more than one node running, you may include it in the same command in a comma-separated, no-white-space list. Alternatively, if you are the only one using the testbed, you can shutdown all the nodes by running omf tell -a offh -t all.
