A 'notification-event' is the transmission of a single trap or inform PDU to a list of notification destinations. If additional nat packets are discarded within the throttling period, then notification-events for these changes should be suppressed by the agent until the current throttling period expires. At the end of a throttling period, one notification-event should be generated if any NAT packet was discarded since the start of the throttling period. In such a case, another throttling period is started right away." -- 1.
