[0051] figure 1 It is a schematic configuration diagram of the network system according to the first embodiment of the present invention.

[0052] figure 1 The illustrated network system includes, for example, information transmission devices 2A, 2B, 2C, and 2D on the data transmission side of sensor devices in a state where data communication is possible, as shown in a publisher-subscriber model used in an IoT system, for example. , 2E, 2F and agent 3, and information storage devices 1A, 1B, 1C, 1D and setting management device 5 as an information distributed storage system storing transmitted data, and have, for example, a data receiving side as an application program The information receiving devices 4A, 4B, 4C, 4D. also, figure 1 The illustrated network system is just an example. In the network system, there may be any number of information transmitting devices and information receiving devices greater than or equal to one, and any number of inform...

Abstract

In order to enable data transmitted from an information transmission device to be stored in a distributed manner without requiring the duplication of or transmitting / receiving of data between information storage devices, in each of a plurality of information storage devices a superintended endpoint is determined under the control of a data writing unit, on the basis of preset information indicating a correspondence relationship between the information processing devices and an endpoint superintended by the relevant information storage device. On the basis of a first correspondence table whichis stored in a shared setting storage unit and in which endpoints and identifiers indicating the type of data acquired by the relevant endpoint are associated, data that is transmitted together with the identifier associated with the superintended endpoint is acquired from data transmitted from a data transmission device, and the acquired data is stored in the information storage device. Under thecontrol of a correspondence updating unit the correspondence with the superintended endpoint is written to a second correspondence table stored in the shared setting storage unit.

Description

technical field [0001] The invention relates to an information distributed storage system, method and program for distributed storage of data. Background technique [0002] In the IoT system that has been attracting attention in recent years, for example, there is a need for base software that can store data sent from many types of sensor devices without omission, and read arbitrary data from the accumulated data at arbitrary timing. . [0003] In IoT systems, most of the data sent from sensor devices is small in size and sent at high frequency. Therefore, such data is usually sent to the base software for aggregation through a lightweight publisher-subscriber model message protocol represented by MQTT (Message Queueing Telemetry Transport). [0004] However, it is expected that there will be no permanent area in the sensor facility, and no workers will be permanently stationed around it. Therefore, it is necessary to continuously and seamlessly write data into the storag...
