3.2.2 Timers

Heartbeat: This timer expires repeatedly, at a regular interval. The default interval is once every 30,000 milliseconds. The lowest interval is once every 1,000 milliseconds. The highest interval is once every 4,294,967,295 milliseconds.

Idle-Timeout: This timer is used for cleaning up 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 timeout period is 10 seconds. There is no maximum value defined for the timeout period.

Lag-Timer: This timer is used for implementing the delay required for the Announce requests as specified by the X-Player-Lag-Time (section 2.2.6.19). The initial value is 0. The timer value SHOULD NOT exceed 15 seconds.
