You can do number #1 pretty easily. Look up the Connection by DPID. Connections have a socket to their switch, and just use the socket's .getpeername(). Something like...
print core.openflow.connections[dpid].sock.getpeername() I've thought about wrapping the sock.getpeername() part with a nice property, but haven't done it. -- Murphy On Jun 27, 2013, at 2:25 PM, Bob Lantz wrote: > 1.
