Suppression of Duplicate Messages
You can set the Duplicate Message Suppression Mode so that VPO
suppresses:
All duplicate messages that match a particular condition.
All duplicate messages whose input events are identical.
All duplicate messages whose output messages are identical.
When you activate the suppression of duplicate messages, you can also
define either:
A time interval over which VPO suppresses duplicate messages, and
then retransmits them after this period has elapsed, or
A threshold for a duplicate message counter; VPO increments the
counter until it crosses the threshold and then allows the
retransmission of the duplicate message.
