Dear All,

I am able to create my set up with NOX and openVswitch. My set up is working 
fine. Nox is able to add flow entries in switches i connected with it. I have 
used following command at nox to connect it with openVswitch.

./nox_core -i ptcp:2525 switch.
I know with this command src/nox/apps/switch/switch.cc file is called. so I 
have 
grepped this code and understood the way nox adds entries in openflow switches

I have checked in openVswitch as well that flows are automatically added  in 
these when i run ping command.

But this it is not understood to me that how nox (switch.cc) calculates the 
flow 
for a particular source and
 destination, 

I checked the packets through tcpdump and found some arp requests and reply. So 
does it mean that this  finds the path to a particular switch through these 
requests?  How does it discover the topology like ospf?

Can you please also let me know that which part of the code i should look for 
this.


Many thanks in advance to clear my doubt.

Regards,
Sachin
