ORBIT-USER: Some questions in ORBIT testbed

Yes, that is correct. A possible implementation path is as follows:

1) Reserve one of the sandboxes (for e.g. sb2). Refer to:
    http://www.orbit-lab.org/wiki/ReservationTutorial
2) Log into the reserved sandbox during your scheduled timeslot. Refer to:
3) Image the nodes on the sandbox with the baseline.ndz disk image. Refer
    to: http://www.orbit-lab.org/wiki/HowToGetStarted
4) Once imaging finishes, turn ON the nodes - refer to:
    http://www.orbit-lab.org/wiki/FAQ#can-i-reboot-or-power-cycle-my-nodes
    Remember that there are only two nodes on each sandbox - node1-1 and
    node1-2.
5) ssh into one of the nodes:

>From here on, the environment should be very similar to one on your lab PC 
or laptop. Check out: 
http://www.orbit-lab.org/wiki/FAQ#how-do-i-install-software-on-the-nodes

Once your slot is coming to an end and you want to save your work, you can 
either copy your software back to your ORBIT home directory. 
Alternatively, you can save the image on the disk and use it for future 
use. Check out:

There are other related answers in the FAQ as well.

>From my understanding, the concepts of topology, application, 
prototype, mapping and staging are from the point of view of running an 
experiment on the ORBIT testbed. I believe the implemented network 
protocol belongs to the "application" section - this is from 
nodehandler's point of view, which sees your network protocol as an 
"application" that it needs to run on a set of nodes during an 
experiment.

Hope that helps,
Kishore
