Title:
DISTRIBUTED INFORMATION MEMORY SYSTEM, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/087786
Kind Code:
A1
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 which is 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 the control 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.
