Hi,

This Ryu app may be helpful.
https://github.com/osrg/ryu/blob/master/ryu/app/simple_switch_13.py#L50-L63

Details are described in Ryu-BOOK.

Would you like to try to make the app based on dumper.py?

Note:

 switches.py: switch(datapath) discovery app using ofp_event
 dumper.py: test and example app using switch discovery event
