Abstract: [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.

Abstract: [Technical Problem] Placing optical performance monitors at all of nodes and links in a network results in a high monitoring capital expenditure (CAPEX). [Solution to Problem] A controller connected to a network and a plurality of nodes includes: a first degraded path detecting means for detecting a wavelength path as a first degraded path, whose quality is detected to be degraded, based on received parameter of wavelength paths in the network; a correlation path computation means for computing a correlation path which is correlated to the first degraded path; a second degraded path detecting means for detecting a second degraded path from the correlation path; and a failure localization means for localizing a node or a link connecting nodes as a failure node or a failure link, wherein the node or the link are traversed by both of the first degraded path and the second degraded path.
