Agent-Level Fault Data Correlation in Network Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network management systems face inefficiencies in fault and performance management, requiring extensive data transfer across hierarchical levels, leading to bandwidth and processing power issues, and often fail to identify the root cause of problems due to uncorrelated fault and performance management data, resulting in slow response times and reduced quality of service.
Innovation Solution
The method involves correlating fault and performance management data at the agent level using configuration management relationships, reducing the need for raw data transfer to higher levels by sending summarized information, thereby reducing bandwidth and processing requirements, and enabling faster, more automated management processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If fault and performance management data is transferred across hierarchical levels in conventional network management systems, then complete data is available for analysis, but bandwidth consumption increases and processing time is extended
Solution Approach 1:
The patent extracts and processes fault and performance management data locally at the agent level before transmission. By taking out the correlation function from the central management system and placing it at the agent level, only essential summarized information needs to be transmitted upward, reducing bandwidth consumption while maintaining data completeness for root cause analysis
Solution Approach 2:
The patent segments the data processing function across different hierarchical levels. The agent level performs local correlation of fault and performance data using configuration management relationships, while the management level receives pre-processed information. This segmentation reduces the processing burden on upper levels and minimizes data transmission requirements
2Loss of energy
If fault and performance management data is not correlated at the agent level, then data transfer requirements are reduced, but root cause identification capability is lost
Solution Approach 1:
The patent performs preliminary correlation of fault and performance management data at the agent level using available configuration management relationships before data is transmitted upward. This preliminary action enables root cause identification to occur at the lowest possible level in the hierarchy, maintaining diagnostic capability while minimizing data transmission requirements
Solution Approach 2:
The patent introduces configuration management relationships as an intermediary mechanism that enables correlation between different network entities. These relationships serve as a mediator that allows the agent to understand connections between faults and performance data without requiring complete data transfer to upper management levels
3Measurement precision
If extensive raw data is transferred to higher management levels, then comprehensive analysis is possible, but response time increases
Solution Approach 1:
The patent performs preliminary correlation and analysis at the agent level before transmitting data upward. By conducting initial processing locally, the system achieves faster response times while still enabling comprehensive analysis at higher levels with pre-processed information, eliminating the need to transfer extensive raw data
