<P>PROBLEM TO BE SOLVED: To execute efficient transmission in optical transmission that uses wavelength multiplex, using a combination of different wavelengths or a different number of wavelengths for each transmission destination or by each service. <P>SOLUTION: A combination of wavelengths used for transmission is determined, corresponding to a destination of a transmission signal or a service to which the transmission signal belongs; a plurality of the determined combinations of wavelengths, corresponding to a plurality of destinations or a plurality of services are arranged into the same transmission signal so that the wavelengths of the combinations each other do not overlap. Alternatively, the number of wavelengths used for transmission is determined, corresponding to a destination of a transmission signal or a service to which the transmission signal belongs; the number of wavelengths determined, corresponding to a plurality of destinations or a plurality of services, is assigned to the same transmission signal in a range which does not exceed the predetermined maximum number of wavelengths. It is also possible to execute first from processing related to destinations or services belonging to a high-priority group. <P>COPYRIGHT: (C)2009,JPO&INPIT |
