METHOD FOR GAP ANALYSIS FOR NETWORK TOPOLOGY INSPECTION IN ETHERNET-BASED NETWORK

摘要

PURPOSE: A method of gap analysis for network topology inspection in an Ethernet-based network is provided to finally analyze network analysis result in a network comprising a two-tier switch or hub and detect a deep segment of a form adjacent to actual network, thereby exactly comprehending network topology. CONSTITUTION: A detected gap is saved in a gap queue(S301). The number of island edge switches is checked by drawing the gap in the gap queue one by one(S303). When the number of island edge switches is less than a setting number, a deep segment between the island edge switches is considered to connected with one Ethernet link(S311). When the number of island edge switches is more than the setting number, a partitioned atom gap is saved in an atom gap queue by performing a PCT(Patch Crossing Test) around an edge switch belonging to the drawn gap(S324). Topology of the gap is interpreted by analyzing final result about the PCT of time when the atom gap is generated.
