Yes i have to do even the message because the switch in mininet emulated by OVS had to send to the controller a message that says to it that there's too traffic in it so the controller have to say to others ignore it..i don't know if a similar message exist i mean it's implemented yet do you know if this kind or similar message exist yet? The first part to ignore dpid i have done that in pox but now i want to do this in ryu..so this is why i asked you how to do the same thing in ryu Thank for your help and i hope you can answer fast to me Best regards
