Network Fault Restoration Analyzer Using Topology Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for estimating restoration handling in communication networks fail to account for the number of failure occurrences and network topology, leading to inadequate restoration strategies when failures recur or vary by apparatus position.
Innovation Solution
An information analysis apparatus that inputs fault location and factor information, using stored restoration handling method rules to analyze and provide appropriate methods based on past faults and apparatus conditions, including network topology and redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If restoration handling method is estimated from failure cause and apparatus type only, then the estimation process is simple, but the restoration method cannot adapt to recurring failures or different network topologies
Solution Approach 1:
The system pre-stores multiple restoration handling method rules in the storage unit, each rule containing apparatus type, failure cause, number of failure occurrences, and restoration method information. When a failure occurs, the analyzer quickly retrieves and matches the appropriate pre-defined rule without performing complex real-time analysis, thus achieving adaptable restoration methods while keeping the system relatively simple.
Solution Approach 2:
The patent adds new dimensions to the restoration method selection criteria by incorporating 'number of failure occurrences' and 'network topology' alongside the traditional 'apparatus type' and 'failure cause'. This multi-dimensional approach enables the system to provide different restoration methods for recurring failures (e.g., temporary vs. permanent restoration) and for different network configurations, significantly improving adaptability.
2Measurement precision
If restoration method considers number of failure occurrences and network topology, then restoration accuracy improves, but information processing complexity increases
Solution Approach 1:
The system pre-stores multiple restoration handling method rules in the storage unit, each rule containing apparatus type, failure cause, number of failure occurrences, and restoration method information. When a failure occurs, the analyzer quickly retrieves and matches the appropriate pre-defined rule without performing complex real-time analysis, thus achieving adaptable restoration methods while keeping the system relatively simple.
Solution Approach 2:
The patent uses a rule-based approach where restoration methods are stored as pre-defined templates or copies. Instead of analyzing and generating restoration methods from scratch for each failure, the system copies and applies appropriate pre-stored rules that match the current failure conditions, reducing processing complexity while maintaining precision.
3Reliability
If multiple restoration methods are stored and analyzed based on past faults, then appropriate restoration handling can be provided, but storage and analysis resources increase
Solution Approach 1:
Each restoration handling method rule in the storage unit is designed to be universal, containing parameters for apparatus type, failure cause, number of failure occurrences, and restoration method. A single rule can apply to multiple similar failure scenarios across different apparatuses and network configurations, reducing the total number of rules needed while maintaining high reliability for various failure situations.

AI summary
An information analysis apparatus according to an embodiment includes an input unit that inputs information indicating an apparatus that is a fault occurrence location in a communication network and a factor of a fault, a storage unit that stores a restoration handling method rule in which the apparatus that is the fault occurrence location, the factor of the fault, and an appropriate restoration handling method for the fault are associated, and an analyzer that analyzes an appropriate restoration handling method for the apparatus and the factor indicated by the information that is input, based on information related to a past fault for the apparatus that is the fault occurrence location, or a condition inherent in the apparatus that is the fault occurrence location, from the restoration handling method rule.
