Patent ID: 7821968

Claim:
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 M 1 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 M 2 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 M 1 and the mapping table M 2 of the MvP table, and normalize the table by deleting an entry corresponding to a port from the mapping table M 2 when the aforesaid port is seen in both the mapping table M 1 and the mapping table M 2 , and detect automatically the connection information between the layer-2 switches by using the MvP table at the end of the normalization.
