Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network Function Virtualization (NFV) environments are complex and require specialized fault management methods due to the added software instances and management entities, differing from common virtual environments, necessitating effective fault reporting and processing techniques.
Innovation Solution
A fault management method involving a virtualized infrastructure manager (VIM) that acquires and generates comprehensive fault information, including faulty entity identifiers and types, to perform repair or reporting processing, prioritizing hardware over software entities and utilizing correlated fault information for comprehensive processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fault information is collected from multiple NFVI entities and correlated, then fault processing comprehensiveness is improved, but information processing complexity increases
Solution Approach 1:
The patent merges fault information from multiple NFVI entities into unified comprehensive fault information records. The VIM consolidates first fault information from a first NFVI entity with second fault information from correlated NFVI entities, creating integrated fault records that improve processing comprehensiveness while managing complexity through systematic integration.
Solution Approach 2:
The VIM acts as an intermediary that receives, correlates, and processes fault information from multiple NFVI entities. It mediates between the distributed fault sources and the fault management system, organizing raw fault data into structured comprehensive fault information that balances completeness with manageable complexity.
2Measurement precision
If fault information from correlated NFVI entities is integrated, then fault detection accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by establishing correlation relationships between NFVI entities in advance. When faults occur, the VIM can quickly identify and integrate information from pre-identified correlated entities, improving detection accuracy while minimizing additional processing time through预先 prepared correlation data.
3Reliability
If comprehensive fault information is generated and processed, then fault repair accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments the fault management process into distinct functional modules: fault information acquisition, correlation identification, comprehensive information generation, and repair execution. This segmentation improves repair accuracy by ensuring thorough information gathering while managing system complexity through modular, organized processing stages.
