<p><P>PROBLEM TO BE SOLVED: To provide a device monitoring network system and a trap management method of SNMP (simple network management protocol), capable of reducing processing load and network traffics by efficiently performing omission check of TRAP and retransmission processing of TRAP for TRAP which occurs in large quantities. <P>SOLUTION: The trap number is counted for every unit time in a TRAP generation part A of a network element NE (monitoring object device), and when the trap number exceeds a threshold, traps are sorted to trap groups sorted by monitoring function item. Each trap is transmitted from a TRAP transmission part C to a NMS (network management system) while assigning a trap group number assigned to each trap group and a trap sequence number. In the NMS, continuity check of receipt is performed for each trap group, and omission check and retransmission request of traps are performed by trap group units. TRAP for which retransmission is requested is reedited for each trap group and transmitted as one trap to the NMS. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
