Abstract:
1. A network design device comprising: a division unit for dividing a network having a plurality of channels, branch nodes, and paths into a plurality of linear partial networks using a predetermined terminal node or each branch node as the terminal nodes by provisionally allocating a device terminating one or more channels to be used to the terminal node and each branch node; an allocation unit for allocating one of a linear relay device and a reproduction relay device to a node constituting each of the partial networks according to signal performance of a fiber allocated between the nodes; a path formation unit for forming a particular path by combining the partial networks to which one of the linear relay device and the reproduction relay device has been allocated by the allocation unit; and a deletion unit for deleting the device terminating the channel provisionally allocated to the branch node for each path formed by the path formation unit according to the signal performance.
