Abstract:
1. A network designing device comprising: a first dividing unit dividing a design object network in which more than two terminal nodes and more than one branch nodes are connected through some other nodes into a plurality of linear network, each linear network having one of the terminal nodes and one of the branch nodes at both ends of each linear network; an input unit allowing a user to assign, to the nodes in the linear networks, arrangement of regeneration repeaters or supplies materials thereof; a second dividing unit dividing the linear networks into a plurality of regeneration repeating sections by dividing at the nodes that the regeneration repeaters are assigned by the user; a device arranging unit arranging transmission devices at the nodes positioned in the regeneration repeating sections based on traffic information, building information, or transmission line information input by the user; a path extracting unit extracting a plurality of assumed paths assumed based on the result of arranging the transmission devices in the regeneration repeating sections; a determining unit determining transmission permission/inhibition for each assumed path; and a display unit displaying a result of the determination performed by the determining unit.
