Abstract: A control apparatus for registering a connection state between component devices constituting a distributed optical transmission apparatus in a database includes: a device setting unit which performs setting such that light is output from a component device that is a connection source; and a registration processing unit which acquires a light reception level of each port in each component device on a side receiving the light, identifies a port having a light reception level higher than light reception levels of other ports, and registers a component device having the identified port and the identified port in the database as a connection destination of the component device that is the connection source.

Abstract: A control apparatus includes an optical wavelength change control unit that specifies, in response to a request to change a wavelength band of a first optical wavelength path used by a first transmission apparatus and a second transmission apparatus to a wavelength band of a second optical wavelength path, a first route between routers which is affected by the request and a service which uses the first route and that specifies a second route between the routers which detours the specified service; a router control unit that transmits a request to detour the specified service to the second route, to a start-point router and an end-point router on the first route; and a transmission apparatus control unit that transmits a request to change the wavelength band of the first optical wavelength path to the wavelength band of the second optical wavelength path, to the first transmission apparatus and the second transmission apparatus.

Abstract: A control device includes: a transmission configuration information storage unit configured to manage a transmission path that connects the plurality of transmission apparatuses to each other, and whether a redundant configuration in a transmission layer is available for the transmission path; a route information storage unit configured to manage a route configured between the plurality of routers and a transmission path used on the route; and a transfer path establishing unit configured to, in response to an establishment request including a requirement for the redundant configuration for a transfer path connecting the plurality of routers to each other, refer to the transmission configuration information storage unit and the route information storage unit, establish a transfer path using a redundant route when a redundant configuration in a transfer layer is required as the requirement in the redundant configuration, and establish a transfer path not using the redundant route but being linked to the transmi
