A wavelength path control system, a wavelength path controlling method, and a storage medium for storing a wavelength path controlling program

摘要

[Technical Problem] With an increase of network traffic, it is desirable to increase the wavelength path availability instead of placing more wavelengths into a fiber. [Solution to Problem] A wavelength path control system according to an exemplary aspect of the invention includes: a path computation means for computing which existing wavelength path is needed to be monitored when receiving a request for setting a new wavelength path or a request for configuring a wavelength path from a node; a monitoring means for monitoring signal quality of the existing wavelength path needed to be monitored and the new wavelength path; and a wavelength path control means for controlling to continue or stop setting the new wavelength path or configuring the wavelength path, based on the signal quality monitored by the monitoring management means.
