Dear Nox Developers,
I am interested in writing a NOX application which sends a command to an
openflow switch using "send_openflow_command"
and receives the reply. I have been going through the nox 0.6 source code
with openflow 1.0 that i got using Git.
As far as i know from the source code walkthrough, at Nox, the ofp header
is put in the transmission queue for transmission
and this returns "0" if the header is put in transmission queue or any
positive error value if that is not sucessful.
Instead i want to send as well as receive the reply from a openflow switch.
say for example i want to know the ports associted with the openflow
switch, how to receive the reply
from switch in my application?
only the flow fetcher application is using the "allocate_openflow_xid"
which i think can be used to get the reply
with a unique transaction id. can somebody point an example how this can be
done? Is there any API similar to
ports = send_command(dpid,ofh[GetPortStatus, xid], block). ?
Regards
Karthikeyan R
