Subject: Re: [Ryu-devel] How to obtain ip address of hosts
Hi Zhang and Thanks a lot ??????!
Excuse me for jumping in.
Please refer to the Ryu-Book for getting started.
For example, "Switching Hub" section describes how to get MAC address of hosts
on Ryu application. I guess you can also get IP address in the similar way.
http://osrg.github.io/ryu-book/en/html/switching_hub.html
Thanks,
Iwase
