摘要： Provided is an information processing system, including a processor, a storage device and a display device. The storage device stores images captured by imaging devices. If an image of a moving object is selected as a search query, then the processor executes a similarity search on the images stored in the storage device, with the selected image as the search query. The display device displays images attained as results of the similarity search. If an image of a moving object is added as a search query, then the processor executes a similarity search with all selected images as search queries. The display device updates images to be displayed such that images attained as results of the similarity search performed with all the selected images as the search queries are displayed.

摘要： A passage channel is calculated by taking into account a plurality of requirements having different importance degrees. A channel calculation unit (202) of a transport control server (100) calculates a plurality of passage channel candidates with respect to a passage setting request wherein an active passage candidate and a standby passage candidate are paired in the passage channel candidate; and calculates the occurrence number of phenomena that violate a predetermined requirement relating an operation of the active passage and the standby passage, or a value of a network element for determining whether the requirement is violated, with respect to each passage channel candidate. A cost calculation unit (205) calculates the cost of a passage channel from the calculated number of occurrence, network element value, and a predetermined cost calculation coefficient corresponding to the requirement. A GUI control unit (display control unit) 201 displays identification information of the passage channel candidate, the number of occurrences or the network element value, and the cost, as a list on, for example, a management terminal.

摘要： It is intended to shorten the time required for a path recalculation and a path switching upon occurrence of a failure. A path generation unit of a transport control server (TCS) S-1 generates the normal path information in accordance with the topology information of a network and the resource information which are set. Also, the path generation unit generates in advance the backup path information for occurrence of the failure based on the prediction topology information and the prediction resource information which have been modified in accordance with a predicted failure position. The path generation unit stores the generated backup path information in a data storage unit. A path information notification unit of the TCS (S-1) notifies nodes N of the generated normal path information. A failure information acquisition unit of the TCS (S-1) detects the occurrence of the failure. If the failure information acquisition unit detects the occurrence of the failure, the path information notification unit notifies the nodes N of the backup path information stored in the data storage unit.
