Setting OpenFlow timers
An OpenFlow switch supports the following timers:
• Connection detection interval—Interval at which the OpenFlow switch sends an Echo Request
message to a controller. When the OpenFlow switch receives no Echo Reply message within three
connection detection intervals, 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.
