Hallo ryu - devel team,
I try to implement an OpenFlow controller with a special Update
algorithm, which is called WayUp and is discribed in this paper:
https://www.net.t-labs.tu-berlin.de/~stefan/hotnets14update.pdf . For
this purpose I modify the app "ofctl_rest.py".
My test environment consists of a mininet VM with ovs as switch and ryu
as controller.
For the update algorithm I need barrier requests.
I send a barrier request to a switch and get a barrier reply from that
switch. That the barrier replay is send I can see with wireshark. The
problem is that in the controller app I can't recieve the barrier
replay. I try to recieve it with the following code:
@set_ev_cls(ofp_event.EventOFPBarrierReply, MAIN_DISPATCHER)
def barrier_reply_handler(self, ev):
# code
But the method is not triggered.
Please help. What do I wrong?
