Thank you for your reply!
Bundles seem to be the right way to go at it. I have one more question though:
is there any information on how to use bundles? Unfortunately, I couldn’t find
enough information.
I don’t understand how to create a bundle message and how to use the
OFPBundleCtrlMsg and the OFPBundleAddMsg classes to bundle multiple flow-mod
messages together and then send them all at once with the
datapath.send_msg(msg) method.
