Hi Martin

We are looking for a full topology discovery on network
from your email - it looks like nox_core module can only provide

1. link discovery between switches
2. nodes discovery

But there is no information about the node connect to what ? - there could be 
intermediate devices....etc...

So - openflow switch and nox components can give a full topology or not?

Thanks

Thuymai

Alternatively, you can listen for host_bind_event which is thrown for each new 
host detected.  It contains the dpid, port, and addresses associated with each 
detected host.
