You mean "How to run KulCloud Cbench tool with Ryu? And is
there any app for cbench for OpenFlow 1.3", right?
I don't know about "KulCloud Cbench tool" further...
Just know where to get the source code.
https://kulcloud.wordpress.com/tag/cbench/
OTOH, I attached to the Ryu-side application for tests.
This is a fork of cbench.py which is one of the built-in
apps of Ryu.
https://github.com/osrg/ryu/blob/master/ryu/app/cbench.py
Thanks,
Iwase
