Network Fault Pattern Analyzer for Heterogeneous Root Cause Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network management products are limited in their ability to analyze network faults effectively, especially in heterogeneous environments, due to their focus on breadth rather than depth of analysis, and lack the capability to diagnose the root cause of faults, leading to a plethora of data for administrators to interpret.
Innovation Solution
A network fault pattern analyzer that transforms data from various sources into a meta-language, allowing comparison with known fault patterns to identify and diagnose root causes, providing depth of analysis and suggesting remedial actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network management products focus on breadth of analysis to support heterogeneous devices, then device compatibility is improved, but fault diagnosis capability deteriorates
Solution Approach 1:
The patent introduces a fault pattern language as an intermediary representation layer between diverse network device data formats and fault diagnosis requirements. This mediator enables the system to handle heterogeneous device data while maintaining focused fault analysis capability through standardized pattern matching operations.
Solution Approach 2:
The patent segments the complex fault analysis task into discrete fault patterns, each representing a specific fault type or condition. This segmentation allows the system to maintain broad device support while providing deep, focused analysis for each specific fault pattern through specialized matching algorithms.
2Ease of operation
If network management products provide command and control capabilities for homogeneous devices, then ease of operation is improved, but adaptability to heterogeneous environments deteriorates
Solution Approach 1:
The patent creates a universal fault pattern language that can represent and match fault conditions across multiple device types and vendors. This universal representation enables consistent command and control capabilities while adapting to heterogeneous environments through the standardized pattern matching approach.
3Adaptability or versatility
If multiple vendor-specific tools are used to manage heterogeneous devices, then device compatibility is improved, but data complexity increases
Solution Approach 1:
The patent merges the functionality of multiple vendor-specific management tools into a unified fault pattern matching framework. By combining diverse data sources and management functions into a single coherent system that operates on standardized fault patterns, the patent reduces data complexity while maintaining broad device compatibility.
Data Source
AI summary
Network state information and network topology information associated with a network is retrieved and transformed using a meta-language. The transformed data is compared against known network fault patterns to identify a matching network fault signature. The matching network fault signature is used to diagnose potential cause(s) of network problems that resulted in the matched signature.
