Abstract
An optical network designing device that designs a path of an optical network that includes an asymmetric optical hub site, comprising: a path calculating unit that calculates a requested traffic path without a limit to a number of connections of the asymmetric optical hub site; a violation determining unit that determines whether a limit to the number of connections is violated in the asymmetric optical hub site through which the traffic path calculated by the path calculating unit passes; a removal selecting unit that selects a removal connection to be removed from the determined asymmetric optical hub site when the violation determining unit determines that the limit to the number of connections is violated; and a path recalculating unit that recalculates a traffic path that passes through the asymmetric optical hub site from which the removal connection selected by the removal selecting unit has been removed.
