If a temporary network disruption occurs for less time than the Receiver warning timeout property, the
Receiver will not display a warning, and the user will experience only a brief drop in Remote Display
Window interactivity. This means, for example, that a user moving or scrolling a window might see a
momentary decrease in interactivity. If the user is not interacting with the Remote Display Window
during a temporary network disruption, the network disruption may not even be noticeable (unless
dynamic content such as video fails to update at an appropriate rate).
NOTE: In many cases, the TCP/IP network stack is able to detect and resolve network errors, such
as a transmitted packet not being acknowledged. However, if a more serious problem occurs, such as
a network cable being unplugged from the local computer, the TCP/IP stack will notify the RGS
Receiver of a network exception. In this case, the RGS connection will be closed immediately,
independent of whether a network timeout property has been exceeded.
After the Receiver warning timeout property has been exceeded (two seconds, in this case), the
Receiver Remote Display Window will dim and display a warning message to the user. The dimmed
window and warning message notify the user of the potentially stale contents in the Remote Display
Window. During this time, the Remote Display Window will appear unresponsive to the user. If
connectivity returns, the Remote Display Window will return to its normal appearance and
interactivity.
If the connection loss extends beyond the Receiver error timeout property (30 seconds, in this case),
the Remote Display Window and the Receiver connection will be closed, and the "Connection Lost!"
error dialog will be displayed.
The recommended Receiver timeout strategy is to set a short warning timeout property and a longer
error timeout property. With these settings, the user is notified of potential network disruptions
relatively quickly while allowing sufficient time for the network to possibly recover. For networks with
