Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Networks experience frequent link oscillations due to factors like temperature and humidity, leading to increased packet loss and computational challenges from frequent rerouting and switch-back operations, with existing management systems lacking effective risk management for oscillating links.
Innovation Solution
A method and apparatus for link processing that calculates risk information based on state changes and duration, performs path computation, and implements risk suppression to identify and adaptively manage risk links, reducing packet loss and optimizing network operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional link management systems are used, then basic link monitoring is provided, but they cannot effectively identify and manage risk links, leading to frequent packet loss and service disruptions
Solution Approach 1:
The system performs preliminary risk assessment by calculating risk values for links before actual failures occur. It proactively identifies potential risk links using historical data and state change patterns, enabling preventive management rather than reactive response to failures
Solution Approach 2:
The risk management system dynamically adapts to changing network conditions by continuously updating risk values based on real-time state changes and historical patterns. The risk assessment is not static but evolves with network behavior, allowing the system to adapt to different operational scenarios
2Reliability
If frequent rerouting and switch-back operations are performed to handle link oscillations, then link availability is maintained, but packet loss increases and network stability deteriorates
Solution Approach 1:
The system applies preliminary anti-action by identifying risk links before they cause oscillations and taking preventive measures. By suppressing path switching on identified risk links, it prevents the harmful cycle of frequent rerouting and switch-back operations that would otherwise occur
Solution Approach 2:
The system converts the potentially harmful effect of link oscillations into a benefit by using historical state change data to identify patterns. These patterns, which would normally indicate instability, are transformed into predictive information that enables proactive risk management and prevents future oscillations
3Adaptability or versatility
If path switching is performed frequently to adapt to link state changes, then network adaptability is improved, but the risk of packet loss and service disruption increases
Solution Approach 1:
The system implements feedback by continuously monitoring link state changes and using historical data to update risk assessments. This feedback loop enables the system to learn from past behavior and make informed decisions about path switching, balancing adaptability with service continuity
Solution Approach 2:
The system changes the parameter of path switching behavior by introducing risk-based suppression. Instead of uniformly responding to all link state changes, it selectively suppresses switching on risk links while maintaining normal switching behavior on stable links, thus preserving adaptability where safe
