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.

Distributed realtime edge-core analytics with feedback

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.

Computer system

The present disclosure discloses method and apparatus to manage insufficient data targeted for partially distributed and partially centralized analytics in mobile or internet of things (IoT) environment. The present disclosure also discloses method and apparatus to get more accurate data if sent data does not have enough accuracy to the certain analytics.

Method and apparatus to manage insufficient data in distributed analytics system

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.

Real time transmission monitoring and anomaly detection

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.

Search system and search method

A computer system comprising a plurality of computers and a storage system, further comprising: a first data processing module configured to process data transmitted from an apparatus; a memory store; a database; a memory store control module; a second data processing module configured to execute predetermined processing using processed data included in a first data range; and a third data processing module configured to execute predetermined processing using the processed data included in a second data range, the memory store control module being configured to: specify a third data range, which is a time range of the processed data to be written to the database; and specify deletable processed data based on the first data range and the third data range.
