NETWORK MAP DISPLAY METHOD AND NETWORK MAP DISPLAY PROGRAM

摘要

The present invention is a method for drawing connections for one or more Layer-2 switches as a tree-type network map, comprising of:;a first step of generating a MvP table consisting of a mapping table M1 and a mapping table M2 based on management information collected from the Layer-2 switches by network monitoring manager H,;wherein said mapping table M1 provides a mapping between MAC address M (H) of network monitoring manager H and a Switch-Port set Row{M(H)} of ports of Layer-2 switches Sj (1≤j≤total number of Layer-2 switches) that detected said MAC address M(H), and;said mapping table M2 provides a mapping between MAC address M(Sj) of Layer-2 switches Sj and Switch-Port set Row{M(Sj)} of ports of Layer-2 switches Sj that detected said MAC address M(Sj);;a second step of normalizing the MvP table,;wherein, if the same Switch-Port element is seen in both the Switch-Port set Row{M(H)} of the mapping table M1 and the Switch-Port set Row{M (Sj)} of the mapping table M2, the MvP table is normalized by deleting Switch-Port elements P(Sj,n) (1≤n≤total number of ports of Layer-2 switches Sj) corresponding to the same Switch-Port from the Switch-Port set Row{M(Sj)} of the mapping table M2, and Connection-information between Layer-2 switches is identified based on normalized MvP table;;a third step of identifying parent-child relationship of Layer-2 switches based on said Connection-information between Layer-2 switches in the second step, and generating a Layered-structure of Layer-2 switches based on said parent-child relationship;;a fourth step of drawing connections for Layer-2 switches as a tree-type network map based on said Layered-structure of Layer-2 switches in the third step.
