Method of automatically recognizing network configuration including intelligent packet relay equipment, method of displaying network configuration chart, and system thereof

Abstract

A method and system is described for detecting a physical device configuration inside a network node and displaying the configuration of a network in connection with a plurality of devices, in a network environment including SNMP-implemented intelligent network devices. ICMP echo requests are sent from an administrator terminal implementing an SNMP manager to individual network devices in the network node so that active devices are detected on the basis of responses therefrom. Then, transfer requests for information stored in the management information bases of the respective devices are sent to the SNMP agents in the individual devices detected, so that the types of the devices in the network node are detected based on the information stored in the management information bases returned.
