Dear,
Sorry for sending again. I have attached the logfile from RYU controller.
Here, dpset for _unregister is not generated when I shutdown the physical
openflow switch. _unregister is generated when OpenFlow switch has
completely reconnected again. Moreover, I have testbed by shutting the
OpenFlow switch for 5 times but _unregister is only generated only one
time. I am planning to make rerouting in my SDN network when the node is
failure. Can anyone suggest me how to detect node failure when the OpenFlow
switch is down.
