Abstract: To prevent a delay in detection of a fault and the like and to cut down a load on a management side while making transmission of data appropriate in consideration of importance and properties of each type of the data in a case in which a large amount of data is transmitted from management target apparatuses. Items with high priority are processed first, and items with a low priority are allowed to be thinned out in accordance with priority and a weight that a management system 10 defines for each data item, thereby reducing a load. The thinning out is performed by limiting the number of data items to be processed once in accordance with a load level. Data acquisition intervals and priority for each item are dynamically changed by reflecting the importance of the data of each item and a change thereof. Trends of data and the like distributed using telemetry are observed and are fed back to load control through control using an AI or a rule base.

Abstract: A transmission system formed by connecting sites through an optical fiber stores at least unique information of the transmission functional devices for each site, connection information, and information of wavelength resources that can be accommodated in the optical fiber in a facility DB as DB information D2. When the number of wavelengths of order information for requesting the number of wavelengths required for transmission of optical signals between sites is larger than the number of wavelengths that can be accommodated in the optical fiber of the DB information D2, the number of wavelengths for each of the transmission functional devices required for enabling the number of wavelengths of the order information D1 to be accommodated in the optical fiber is designed using the design unit. Designed numbers of wavelengths are configured in the corresponding transmission functional devices using the configuration unit.

Abstract: [Problem] In a disaggregated optical transmission system formed by connecting bases including transmission apparatuses having specifications of different vendors through an optical fiber, wavelength information is easily set in the transmission apparatuses at both bases of the optical fiber such that the required wavelength is assigned to the optical fiber.

Abstract: To appropriately monitor a transmission device in an optical transmission system. A monitoring apparatus 1 monitors a plurality of transmission devices 2 having different specifications. The monitoring apparatus 1 includes a monitoring unit 11 that monitors whether a failure occurrence or failure recovery is present in the plurality of transmission devices 2, an analyzing unit 12 that determines whether the failure occurrence or the failure recovery continues for a predetermined period, in a case where the failure occurrence or the failure recovery is present in the plurality of transmission devices 2, a control unit 13 that identifies a cause of the failure, using a plurality of pieces of warning information received from the plurality of transmission devices 2 only in a case where the failure occurrence continues for the predetermined period, and a notifying unit 14 that notifies a higher-level monitoring apparatus of warning information corresponding to the cause of the failure.

Abstract: [Problem] In a transmission system of a disaggregation type formed by connecting, through an optical fiber, sites each including various transmission functional devices having specifications of different vendors, wavelength resources that can be accommodated in the optical fiber can be easily grasped and managed. [Solution] A transmission system formed by connecting sites ach including various transmission functional devices having specifications of different vendors through an optical fiber 15 stores at least unique information of the transmission functional devices for each site, connection information, and information of wavelength resources (the number of wavelengths) that can be accommodated in the optical fiber 15 in a facility DB 34 as DB information D2.
