摘要： 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.

摘要： In a network design apparatus, a full channel evaluator determines whether all wavelength channels for main signals can deliver the main signals of an existing optical network. When it is found that one or more wavelength channels cannot deliver main signals, a chromatic dispersion evaluator determines whether there are a specified number of wavelength channels that satisfy a specified chromatic dispersion condition. An optical signal-to-noise ratio (SNR) evaluator extracts a specified number of wavelength channels out of those satisfying the chromatic dispersion condition in descending order of optical SNRs thereof, and determines whether the extracted wavelength channels satisfy a specified optical SNR condition.

摘要： A residual chromatic dispersion target value at a terminal node is set for each wavelength path, and also, candidates of a dispersion compensation amount settable in each chromatic dispersion compensation module on an optical network are set, and further, computation processing is executed for selecting the dispersion compensation amount in each chromatic dispersion compensation module from the candidates so that the sum of errors between the residual chromatic dispersion amounts and the set residual chromatic dispersion target values at the terminal nodes for all of wavelength paths becomes minimum. As a result, for each wavelength path on the optical network, the dispersion compensation amount in each chromatic dispersion compensation module can be designed in optimum so as to satisfy the desired optical signal quality at the terminal node, while considering the residual chromatic dispersion during the transmission.
