DEVICE AND METHOD FOR EVALUATING TRANSMISSION LINE NETWORK COST, RECORDING MEDIUM RECORDED WITH PROGRAM THEREFOR, AND TRANSMISSION ROUTE SETTING DEVICE

摘要

PROBLEM TO BE SOLVED: To more exactly evaluate the cost performance of a transmission line network. SOLUTION: This transmission line network cost evaluating device 20 is provided with a route setting part 31 for setting the paths of respective multiplex order groups, the setting spot of a transmission medium and route in a pipeline network so as to satisfy the requested demand path, thereby calculating the cost of equipments and obtaining the cost of the transmission line network. The route setting part 31 is composed of an initial route setting part for setting the route of the demand path into shortest route based on the physical distance of a pipeline on the transmission line network and setting a high speed multiplex order group path or the like for accommodating this route equally with the set shortest route of the demand path, pipeline distance correcting part for finding the efficiency of using the band of the transmission medium in the pipeline of the set route of the path and correcting the distance so as to extend the pipeline of low use efficiency, and route resetting part for setting the route of the demand path into shortest route based on the corrected pipeline distance and setting the high speed multiplex order group path or the like for accommodating this route equally with the set shortest route of the demand path.
