Innovation Solution
A method and system for representing and analyzing VoIP networks by mapping observable events to causing events, using a computerized device with a processor, memory, and interconnection mechanism, and software programs to perform operations such as discovering network elements, processing information, and identifying root causes of failures, thereby providing a comprehensive model for VoIP network management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive event mapping and analysis methods are implemented in VoIP networks, then network management reliability and problem identification accuracy are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The patent segments the VoIP network into distinct functional components (gateways, routers, endpoints) and maps events to specific causing events within each component. This segmentation allows comprehensive monitoring without requiring a monolithic complex system, as each segment can be analyzed independently while contributing to overall network reliability.
Solution Approach 2:
The patent introduces an intermediary event correlation system that sits between network components and management systems. This intermediary layer processes and correlates events from multiple sources, transforming raw network data into meaningful problem identification without requiring direct complex integration between all network components and management systems.
2Measurement precision
If detailed event correlation and root cause analysis are performed, then problem identification accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
The patent establishes preliminary event mappings and cause-effect relationships before problems occur. By pre-defining the relationships between observable events and causing events during normal operation, the system can quickly identify root causes when problems occur without performing complex real-time analysis, thus maintaining high accuracy while reducing processing time.
Solution Approach 2:
The patent replaces complex real-time mechanical analysis with pre-computed event correlation models. Instead of performing heavy computational analysis when problems occur, the system uses pre-established event mappings to rapidly identify root causes, substituting computational mechanics with pre-prepared correlation data.
