  • Publication number: 20200183706
    Abstract: Example implementations described herein are directed to the management of data received from an edge side when an update is issued to edge nodes from a core apparatus. When the edge nodes receive the update, the receipt of the update may not be uniform (e.g., due to latency, downtime, etc.), which results in an intermediate state where some edge nodes are updated and some edge nodes are not. Example implementations described herein address the processing of data from edge nodes when such an intermediate state occurs by conducting reprocessing of data when data is transmitted from edge nodes operating from an old configuration.

  • Patent number: 10664496
    Abstract: A computer system, comprising a plurality of computers; and a management computer, wherein a plurality of data stores which store data obtained from a data source and having differing attributes, wherein the management computer has a request allocation unit and holds metadata management information. The request allocation unit is configured to: refer to the metadata management information to select a candidate data store based on analysis results of the data obtaining request including the time attribute of the requested data; determine whether the requested data can be obtained from the candidate data store; determine a data store to which to issue a request for obtaining the requested data; and issue the request to the determined data store.

  • Patent number: 10063405
    Abstract: A network monitoring system compares gathered network information with path information. The comparison between gathered network information and path information provides traceability of automatic and dynamic rerouting function of network and makes it possible to understand the relation between root cause and observed problems. The combined monitoring of data plane with control plane enables identification of the original failure point where behavior is changing though routing failure is propagated around. This will allow the identification of network issues that may lead to service outages and impairments as well as alerting of issues affecting customer satisfaction, and is effective to reduce MTTD (Mean Time To Detect)/MTTR (Mean Time To Repair) and increase service availability in all markets.

  • Patent number: 10019483
    Abstract: A search system executes: a first write procedure of extracting, for data in a data sequence, metadata from the data in input order and writing the metadata into a first storage module in association with identification information uniquely identifying the data; a second write procedure of writing, in parallel with the first write procedure, the data in the data sequence into a second storage module in input order in association with the identification information, and writing the identification information in the second storage module into a third storage module; a reception procedure of receiving a search request including a first search condition relating to search target data; a search procedure of searching a search destination, which is selected from the first and third storage modules in accordance with the search request received, for the identification information satisfying the first search condition; and an output procedure of outputting a search result.

  • Publication number: 20160282445
    Abstract: A position information acquisition system has a terminal and a position information acquisition server for acquiring position information for the terminal. The terminal has a radio wave intensity measurement unit for receiving first radio wave intensities of radio waves received by a plurality of access points and associating the received first radio wave intensities with access point identifiers, and a moving/stationary determination unit for determining whether the terminal is moving or stationary. The position information acquisition server has a position information table in which second radio wave intensities of radio waves received from the plurality of access points are associated with position information, and a radio-wave-intensity/position conversion unit for retrieving second radio wave intensities corresponding to the received first radio wave intensities, and acquiring position information corresponding to the retrieved second radio wave intensities.

  • Publication number: 20140317137
    Abstract: The purpose of the invention is to provide a log management computer that shortens log search time while reducing log storage volume. The log management computer manages a log acquired from a log generating system that generates the log, which is an operation record. The log management computer is characterized by: extracting from a log message contained in the log, both a common portion that is common with another log message and a different portion that is different from another log message; storing the extracted common portion in common portion information of a storage area; storing the extracted different portion in different portion information of the storage area; and if a search request containing a search condition is received, searching for a log message that matches the search condition.
