Network map creating method
First Claim
1. A Network Map generation method, characterized in that the OSI reference model layer-2 switches is automatically discovered and, the aforesaid layer-2 switches connection is automatically detected in the process of the Network Map automatic generation by automatic discovery of network devices or computers connected to the network, comprising:
- a first step is to use the network management information which the NMT (Network Monitor Terminal) obtains from the layer-2 switches, and generates the MvP table comprising of the mapping table M1 between the MAC address of the NMT and the ports of the layer-2 switches on which the aforesaid MAC address was detected and the table M2 mapping the MAC address of the layer-2 switches and the ports of the layer-2 switches on which the aforesaid MAC address was detected, and then,a second step is to compare the mapping table M1 and the mapping table M2 of the MvP table, and normalize the table by deleting an entry corresponding to a port from the mapping table M2 when the aforesaid port is seen in both the mapping table M1 and the mapping table M2, and detect automatically the connection information between the layer-2 switches by using the MvP table at the end of the normalization.

Abstract
By synthesizing the map of an entire network, it provides a method for detecting OSI Reference Model layer-2 switches and evaluating the status of the inter-connection of the layer-2 switches. The NMT (102) which implements the SNMP manager queries the specified management IP-addresses and receives responses from the SNMP agents implemented on the layer-2 switches (103,104,105). From the management information in the responses, the existence of the layer-2 switches is confirmed and the MAC address and port information mapping table MvP table is constructed. Based on the MvP table the inter-connection information of the layer-2 switches is detected.
