An optical network design apparatus includes a memory and a processor. The memory stores a connection limit corresponding to the number of connections between ports. The processor provisionally designs a traffic path across an optical network independently of a connection limit of an asymmetric optical hub, calculates a penalty allowance with respect to the penalty limit of the traffic path, calculates an additional penalty caused on a detour path derived by replacing a port with a replacement port in the asymmetric optical hub, and if an asymmetric optical hub is included in the detour path, generates asymmetric optical hub information about the included asymmetric optical hub, generates, based on the connection limit, penalty allowance, additional penalty, and asymmetric optical hub information, a constraint condition for adopting the traffic path satisfying the connection limit and penalty limit, and calculates the traffic path by mathematical programming under the constraint condition.
