I am a student from TU Berlin and I am planning on doing a project with P4.

Yes, I was able to understand the availability of openflow 1.3. I came
across a mailing thread "Interaction between P4 dataplane and control plane"
between  *Antonin & Ramana, *an image OF.png was attached to understand how

really nice if we could get the image for better understanding of the

Also Please let me know is there any setup instructions to be followed
apart from the one present in P4.org.

My End goal is to program a tunneling protocol using P4, and program the
table entries using Openflow. Is this possible with the current state of
the P4ofagent and P4 switch? Any pointers or suggestions would be really

Custom Controller
|OF 1.3
       P4 OF agent
P4-Switch (Custom Protocol, Flow Based Switching/Routing)

Thanks & Regards,
