Alarm Storm Detection and Management via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network communication systems face performance degradation due to alarm storms, where excessive alarms overwhelm processing capacity, leading to potential network crashes, and existing solutions either fail to detect the issue promptly or provide only short-term, costly upgrades.
Innovation Solution
A method and system that detect alarm storms by categorizing alarms into types based on rate and cause, using an alarm storm detection function to trigger management, buffer and process alarms at a controlled rate, and prioritize critical alarms to maintain network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the network management system processes all alarms as fast as possible, then the processing speed is improved, but the processing capacity is overwhelmed and network performance degrades
Solution Approach 1:
The patent segments alarms into different types (alarm storms and non-alarm storms) based on their characteristics. By categorizing alarms and applying different processing strategies to each type, the system can handle alarm storms specially (preventing them from overwhelming the system) while maintaining fast processing for normal alarms, thus resolving the contradiction between processing speed and network performance
Solution Approach 2:
The system dynamically adjusts its processing behavior based on the detected alarm type. When an alarm storm is detected, the system switches to a special processing mode that prevents overwhelming the management system. This dynamic adaptation allows the system to maintain both high processing speed for normal conditions and network performance protection during alarm storms
2Power
If more powerful machines are upgraded to handle alarm storms, then the processing capacity is improved, but the cost increases and it provides only a short term solution
Solution Approach 1:
Instead of increasing hardware processing capacity, the patent changes the processing parameters and strategies based on alarm type. By detecting alarm storms and applying specialized processing rules, the system achieves effective handling of high-volume alarm scenarios without requiring more powerful (and expensive) hardware, thus resolving the contradiction between processing capacity and system cost
3Loss of information
If the system correlates all alarms during an alarm storm, then the analysis completeness is improved, but the system runs out of processing power and desired results cannot be generated in time
Solution Approach 1:
The patent segments the alarm processing task based on alarm type. For alarm storms, it applies a specialized processing approach that identifies and handles the root cause efficiently. For non-alarm storms, it performs comprehensive correlation analysis. This segmentation ensures that time-critical alarm storms are handled quickly while maintaining analysis completeness for other scenarios
Solution Approach 2:
The system performs preliminary detection and classification of alarm storms before full processing occurs. By identifying alarm storms early and applying appropriate processing rules, the system prevents processing bottlenecks before they occur, ensuring both timely response and complete analysis
