Thanks you i will try it out. The only what I need to do is sending the openflow message to a live datapath ID. But if we apply packet in message scenario, switch will need to send a lot of packet in message in oder to reroute reactively but RYU,shows memory error when running 2 hours. If we can apply the flow rules without packet in message when some node is failed that problem can be resolved.
