Efficient network management system and method of managing the same between network management devices and management object devices

摘要

In a network management system, a data portion of an SNMP packet transmitted/received between an SNMP manager 10 (network management device) and an SNMP agent 20 (management object device) is compressed by a predetermined compression algorithm in a compression/decompression processing section 13, 22 , when the SNMP packet is transmitted. The compressed SNMP packet is decompressed to be reproduced as the SNMP packet by the predetermined compression algorithm in the compression/decompression processing section 13, 22, when the compressed SNMP packet is received. Further, a compression indicating bit [1] is set on a predetermined bit position in the compressed SNMP packet in order to distinguish the SNMP packet from another SNMP packet transmitted/received between the SNMP manager 10 and an SNMP agent 120 (conventional management object device).
