Reliability for simple network management protocol trap messages

摘要: In a Broad Based Data System, one Manager System can control the actions of plurality Agent Systems. The Systems communicate with by sending trap messages. ensures that no messages are lost checking sequence number each received message from particular is higher than previously message. If missing detected, requests re-transmittal associated number. order to prevent flooding an excessive only send given number, N messages, before it re-authorized more Applicants' specific embodiment, authorization in form acknowledgment Trap representing alarm conditions particularly important. Alarm saved as long active. case interruption communications between and Manager, all these active transmitted System. Advantageously, arrangements provide reliable Systems, especially for important Agent.
