Agreed. We'll add a "life of a packet" walk through when we update the documentation.

Hi Martin...
a step-by-step journey from the end-host to switch and then to a controller in 
a very simple network will be of great help. Even for some very basic 
components would enable greater understanding.... regards.

Agreed, this is sorely needed.  To be clear, what happens internal to Nox 
depends on the components being run.  Perhaps a step-by-step description of 
path setup with the basic components (authenticator, routing) would be most 
useful?
Need a little help. I am going through the code of NOX-full version 0.5 (beta). 
I would like to know if there is a object diagram or sequence diagram for the 
code. Specifically I wish to know if there is some flowchart that shows the 
life of a packet in the NOX network right from the moment it originates from 
the end-host, it goes to the OF Switch (reference implementation) and then to 
the NOX Controller.

It will be helpful for me to understand the code if such a reference exists.

Since it is the full version, there are various management applications in the 
component class. I do not have a test-setup to experiment and understand the 
flow in details.

I am able to get some information from the nox-mailing list, as for example the 
description given by Martin here:

http://noxrepo.org/pipermail/nox-dev_noxrepo.org/2009-October/000882.html

and similar posts does through some light. But, if some flow-diagram or 
sequence diagram exists in, would be of great help. Infact, I would eventually 
like to test in the setup similar to the one shown in here:
http://noxrepo.org/pipermail/nox-dev_noxrepo.org/2009-October/000872.html

but, with all the switches in the same subnet (since as Martin mentioned, 
different subnets would not work).

Anyway information on the flow would be helpful.

Regs.
