<p><P>PROBLEM TO BE SOLVED: To facilitate route design of a VLAN on a layer 2 network wherein redundancy is partially completed, and management of required information. <P>SOLUTION: Network configuration information, device setting information, and site information are read from a network configuration information storage part 11, a device setting information storage part 12, and a site information storage part 13 by a graph creation part 14 to generate a graph comprising redundant nodes representing ranges of redundancy, device nodes representing devices constituting the L2 network, and sides connecting the redundant nodes and device nodes belonging to ranges of redundancy of the redundant nodes, and information for route design is generated, and site nodes representing sites are generated and added to the graph, thus route design allowing for partial redundancy and management of information are facilitated. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
