NETWORK ROUTE SELECTION UNIT, NETWORK TOPOLOGY DISPLAY DEVICE, NETWORK ROUTE SELECTION METHOD, NETWORK TOPOLOGY DISPLAY METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To allow for easy selection of a network route by a service provider other than network providers, based on a standpoint other than network operation by the network providers, and to display a network route while abbreviating, so that visibility is improved.;SOLUTION: In an NW route selection unit 10, when start point/end point information D3 of the NW is inputted from a terminal, a route calculation unit 16 searches topology configuration information D5 in a DB13 according to the information D3, and obtains a plurality of pieces of route information D6 corresponding to a plurality of communication routes between the start point and the end point. A management unit 12 generates one or more pieces of shared topology information β1, β2 gathering a plurality of routes having equivalent node connection parts, in respective routes corresponding to the plurality of pieces of route information D6, as routes of the same group. A complexity calculation unit 15 calculates complexity CP, defining that the route complexity is simpler as the number of circulation structures is lowered in the route by shared topology information β, for each shared topology information β1, β2.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
