Transmission path design apparatus, transmission network topology design method, and transmission path design program for designing a communication path topology optimized in view of reducing amount of equipment needed

Abstract

To easily design a communication path topology optimized in view of reducing the amount of equipment needed under the condition that availability against multiple failures in a network is maintained. A transmission path design apparatus () performs: a step (S) of extracting, from the multiple base stations, a first group of base stations whose number of communication-path routes connected is large, based on transmission network model initial data (D); a step (S) of extracting a first group of communication paths connecting the base stations in the first group; a step (S) of calculating a both-end path value (d_i,j) for each communication path in the first group; and steps (Sto S) of determining the communication path whose both-end path value satisfies a predetermined condition as a thinning-out target communication path, and generating output data Dy in which the thinning-out target communication path is reflected on the transmission network model initial data. The optimized output data (Dy) can be generated by extracting a deletable communication path in order from the model of the initial data (D).
