3.2.2 Timers

Idle-Timeout: This timer is used for cleaning up an unused session state. If no requests are received from the client, the Idle-Timeout timer will expire and the server is then free to delete the session state. The minimum allowed value for the time-out period is 10 seconds. This timer does not have a default value.

When the timer is started, the timeout interval SHOULD be set to 3,600 seconds.  If the timer has already been started, attempts to start it again have no effect.  The timer has to be stopped before it can successfully be started again.  Similarly, if the timer is not running, attempts to stop it have no effect.

KeepAlive: This timer is used for sending LinkMacToViewerPing messages. The time-out period SHOULD be 30 seconds. The minimum allowed value for the time-out period is 10 seconds.
