Abstract: To reduce a communication load among data storage devices and data processing devices, a communication device comprises node information storage means for storing identifiers of data devices and processing devices and communication costs, and search processing means for receiving a message, which includes a transfer route of message and a total cost, which is a communication cost of transfer route, and detecting and outputting a closed path, from transfer route, having a negative total cost, or transmitting to the registered data device a message including a new total cost calculated by subtracting a communication cost corresponding to data device concerned from total cost and a new transfer route made by adding communication device to transfer route, and transmitting to the registered processing device a message including a new total cost calculated by adding a communication cost corresponding to processing device concerned to total cost, and new transfer route.

Abstract: Shortest path searcher 105 searches shortest paths from each landmark node to other landmark nodes based on the measured values of distance metrics between the landmark nodes which are stored in distance metric storage 102, and calculates distance metrics along the discovered shortest paths. Coordinate generator 101a generates coordinate axes of a predetermined dimension number from the distance metrics along the shortest paths which are calculated by shortest path searcher 105. Coordinate calculator 104a calculates coordinates of a coordinate-to-be-calculated node from the distance metrics between the coordinate-to-be-calculated node and the landmark nodes and the coordinate axes generated by coordinate generator 101a. Distance metric estimator 134 estimates a distance metric between two coordinate-to-be-calculated nodes whose coordinates are calculated by coordinate calculator 104a, using the calculated coordinates.

Abstract: The present invention determines the type of each piece of system information including a plurality of index values indicative of abnormality levels of a monitoring target device, as follows. The system information and identification information for the system information are sequentially received from the monitoring target device configured to sequentially output the system information together with the identification information for the system information. The piece of the received system information is compared with a predetermined determination criterion and thus determined to be of a particular type based on a result of the comparison. The determined type is output in association with the identification information. Input information indicative of a true type is accepted and stored in association with the identification information. The determination criterion is updated based on the piece of the system information and the information indicative of the true type.

Abstract: Systems that include devices that store data and devices that can process data could not determine which devices are to transfer data. The disclosed management device comprises a load computation unit and a processing allocation unit. The load computation unit acquires processing devices (j) and, for each of complete data sets i, data device list i for data devices storing the complete data set. Based on the communications load between each acquired processing device and data device, the load computation unit computes c?ij, which includes the communications load involved in data processing device j receiving one data unit of complete data set i from the data devices in data device list i. the processing allocation unit determines an amount fij of complete data set i for data processing device j to receive so as minimize a sum includes fij·c?ij.

Abstract: A range search of data is implemented, being a data search method to achieve a constant degree and a logarithmic hop count. A data search device that is located on a network and searches for data shared with another device, includes a dividing unit that divides a logical identifier range based on a logical identifier between own logical identifier and a logical identifier of a successor if a division condition of the logical identifier range requested to search for is met; and a search request transferring unit that transfers a search request including the logical identifier range acquired by the dividing means to a same or different device that meets a forwarding destination condition of the search request.

Abstract: A response-time-difference calculation/request-number converting means (523) calculates a change of throughput based on a response time monitoring result, a target value of the response time, a quantitative model and performance specification information. A server selection means (524) input the performance specification information in the quantitative model acquired to calculate a throughput of each of pool servers, selects a pool server having a throughput corresponding to a throughput larger than and closest to the change of throughput, and instructs provisioning means (513) to execute configuration modification control on the selected pool server (502). The provisioning means (513) modifies the configuration so that the pool server (502) functions as an application server.

Abstract: A predicate-logic retrieval system includes a predicate-logic retrieving section for receiving a predicate query and a metamodel-element built-in predicate (MMEBIP) storage section storing therein MMBEIPs and get-functions in association. If a predicate query includes a MMEBIP, the predicate-logic retrieval system retrieves a get-function from the MMBIP storage section, uses the get-function to retrieve predicate data from a repository storing therein data in a metamodel format, and executes variable identification for the predicate thus retrieved.

Abstract: A network management system includes a schema storage storing a system schema which describes a conceptual structure of a computer network to be managed. Based on input information of two system elements and the system schema, an information acquisition procedure is generated and is used to acquire information of system element and association linking the two system elements from the managed computer network.
