Creating and Loading a Disk Image

To prepare this experiment, we loaded a baseline image onto a node at UCLA.

Try it yourself another time: To load a baseline image onto a node, e.g. node1 at UCLA, run
omf load -i baseline.ndz -t omf.necwimax.node1


Then we installed all the applications on the node. We also prepared 'iput' by initializing it with our iRODS credentials. Then we saved the disk image.

Try it yourself another time: To save a disk image from a node, e.g. node1 at UCLA, run
omf save -n omf.necwimax.node1


When the image saving process concluded, it reported that his disk image had been saved and gave the name of the image. Now, when he wants to run his experiment, he will load his disk image onto the nodes he has reserved:

omf load -i gec16-video.ndz -t omf.necwimax.node1

Clearing Experiment Settings

In addition to loading a fresh disk image, additional steps must be taken to restore the wireless environment to its default state. These commands are run from the console machine at UCLA to reset all of the base station and attenuation settings that a previous experimenter might have used:

wget -qO- "http://wimaxrf:5052/wimaxrf/bs/default"
wget -qO- "http://wimaxrf:5052/wimaxrf/bs/restart"
