Hi,
I think you might need to have a look at the walkthrough on mininet.org. It
might help you a lot.

Hi,
Thanks for your answer.
I also want to know if I use the command 'ping' and generate a ICMP packet,
how to get IP address from this packet?
Is there any method in Ryu API? I did not find it.

Hi,
I use Ryu 4.23 and Mininet 2.3.0d1 (OVS version is 2.5.2) test SDN
applications.
My Ryu controller connect to OpenFlow Switches, and some hosts connect to these
Switches.
I want to know how can I get the ip address of the hosts?
Thanks,
YF
