Abstract
There is provided an information processing apparatus including: a specification unit that specifies a route for converting a wavelength of an optical signal from a first wavelength to a second wavelength and transferring the converted optical signal at a relay node, based on a usage state of a wavelength at nodes that perform communication using an optical signal; and a control unit that controls the nodes in such a way as to perform communication using an optical signal in the route when it is determined that the route is reachable, based on a deterioration characteristic of an SN ratio in a wavelength converter that converts a wavelength of an optical signal from the first wavelength to the second wavelength at the relay node.
