Solution Overview

Problem

In distributed data networks across multiple sites, identifying the storage location of data for retrieval is challenging due to the absence of central control, hindering data circulation and utilization.

Innovation Solution

A communication device within each cluster stores summary data of retrievable information from other clusters, enabling terminals to identify data storage locations through a controlling unit that requests and forwards target data across clusters, with representative devices ensuring secure communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If data are distributed over multiple networks without central control, then data circulation flexibility is improved, but data location identification difficulty increases

Engineering Contradiction:
Improvedata circulation flexibilityVSAvoiddata location identification difficulty
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces a communication device as an intermediary between terminals and data storage locations across different networks. This device maintains a summary table that maps data identification information to storage location information, enabling terminals to identify data locations without requiring central control or direct knowledge of distributed storage positions. The summary table acts as a mediator that translates data identification information into actionable location information.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Difficulty of detecting and measuring

If summary tables are maintained in communication devices, then data location identification is improved, but device storage burden increases

Engineering Contradiction:
Improvedata location identificationVSAvoiddevice storage burden
Core Design Contradiction:
Difficulty of detecting and measuringVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential information needed for data location identification and stores it in summary tables within communication devices. Rather than storing complete data metadata or network configurations, the system extracts and stores only the mapping relationships between data identification information and storage location information. This selective extraction minimizes storage requirements while maintaining effective data location identification capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If representative devices perform authenticated communication, then communication security is improved, but communication complexity increases

Engineering Contradiction:
Improvecommunication securityVSAvoidcommunication complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service authentication where communication devices automatically perform authentication procedures when establishing connections with terminals or other devices. The representative device autonomously manages authentication tasks, verifying credentials and establishing secure communication channels without requiring manual intervention or complex centralized authentication systems. This self-service approach simplifies the overall communication complexity while maintaining strong security through automated verification processes.

Inventive Principle:
Principle #25Self-service

AI summary

A communication device (10) belongs to a first cluster among a plurality of clusters and includes a storing unit (20), a controlling unit (12), and a forwarding unit (11) . The storing unit (20) stores identification information of another cluster that has information being retrievable by a terminal connecting to the communication device in a summary of data held by the other cluster. The controlling unit (12) performs upon receiving a combination of identification information of a second cluster that holds retrieval-target data and identification information of the retrieval-target data from the terminal that accessed the summary, a control to request target data identified by the combination. The forwarding unit (11) forwards the target data to the terminal.
