Setting OpenFlow timers
An OpenFlow switch supports the following timers:
•
Connection detection interval—Interval at which the OpenFlow switch sends two consecutive Echo
Request messages to a controller. The OpenFlow switch can send up to three Echo Request
messages. If none of the requests received a reply, the OpenFlow switch is disconnected from the
controller.
•
Reconnection interval—Interval for the OpenFlow switch to wait before it attempts to reconnect to a
controller.
