Abstract:
1. An optical network design method for accommodating client signals in an optical transponder card, which is included in a multiplex apparatus used for an optical network, for outputting an optical signal by applying a time multiplexing and a wavelength multiplexing to signals from a client, comprising: inputting, to a management apparatus for the optical network, a number of client signal ports of the optical transponder card, an optical signal band of the optical transponder card, a bandwidth of each client signal and a number of client signals having each bandwidth; judging, by the management apparatus, whether or not a client signal having a bandwidth larger than a value of the optical signal bandwidth divided by the number of client signal ports exists; extracting, by the management apparatus, a maximum number of combinations of client signals in which the number of client signals is equal to the number of client signal ports, each combination including at least one client signal having a maximum bandwidth and the total bandwidth of the combination being within the optical signal band, if a client signal having a bandwidth larger than a value of the optical signal bandwidth divided by the number of client signal ports does exist; and selecting, by the management apparatus, a combination of client signals in which a total band of the client signals becomes a maximum from among the extracted combinations as a combination of client signals accommodated in the optical transponder card.
