摘要: A wavelength-selective device includes: a storage in which a wavelength management table is stored; and a processor configured to execute a procedure, the procedure including: searching for one or more paths used as a new path having a first ending time in a network, based on the wavelength management table; selecting a wavelength having a second ending time closest to the first ending time, from one or more wavelengths used on paths found by the searching; and configuring a path using the selected wavelength as the new path.

摘要: A protection channel provisioning method includes: reserving a first protection channel corresponding to a first work channel and a second protection channel corresponding to a second work channel; provisioning a shared protection channel by configuring a circuit of node equipment provided on a shared route on which the first protection channel and the second protection channel are redundantly reserved so that a data signal of the first work channel or a data signal of the second work channel is transmitted via the shared route; and configuring a circuit of branch node equipment provided in a branch node at which the shared protection channel is guided to a first node corresponding to the first protection channel and a second node corresponding to the second protection channel so that the data signal transmitted via the shared protection channel is not guided to the first node and the second node.

摘要: A control apparatus configured to transmit first settings information including first settings contents with respect to an optical transmission device. The control apparatus includes a processor and a storage. The processor is configured to receive a setting error with respect to the first settings information from the optical transmission device, store a setting condition of the optical transmission device that is acquired from the setting error in the storage, determine second settings contents relating to transmission of an optical signal with respect to the optical transmission device based on the stored setting condition, and transmit second settings information including the second settings contents to the optical transmission device.

摘要: A node positioned in a protection path for a working path stores identification information available to identify a source node and an end node. The identification information is contained in a signaling message transmitted to the end node through the protection path from the source node in order to set a usage reservation of the protection path. The node notifies the failure detection to an address identified by the stored identification information in response to a failure detection of the protection path.

摘要: A path calculation device includes: a first storage that stores first topology information for indicating a topology of a network; a second storage that stores second topology information generated from the first topology information stored in the first storage; and a processor that determines a path between a start point and an end point based on the second topology information stored in the second storage and provides path information for indicating the determined path to the network when the path calculation device receives a path calculation request that includes information for indicating the start point and the end point from the network. The processor updates the second topology information stored in the second storage based on the determined path.
