3.2.2 Timers

A keep-alive interval timer sets the time when the server returns a keep-alive response to the client while a request is being processed. The maximum interval is configurable, and the default is set to 15 seconds.

A notification timer triggers the server to complete a NotificationWait request after 5 minutes of no event activity on the Session Context. For details about how the server responds to a NotificationWait request, see section 3.2.5.5.

An idle-time timer measures the time during which the Session Context has no pending requests.
