Dynamic Flow Control Threshold Adjustment for Network Access Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network traffic flow control systems employ a fixed flow-limiting strategy that can lead to mismatches with the operating status of business systems, causing crashes when dealing with high volumes of access requests.
Innovation Solution
A dynamic flow control method that adjusts the flow control threshold values based on real-time analysis of historical data and current load conditions, using an analysis system to determine updated flow control thresholds that align with the operating status of the service application system.

Engineering Contradiction Analysis
1Device complexity
If a fixed flow-limiting strategy is used to control network traffic, then the flow control rule is simple and easy to implement, but the system response time increases and the business system may crash when facing high volume access requests
Solution Approach 1:
The patent transforms the static flow control threshold into a dynamic parameter that automatically adjusts based on real-time system load conditions. The gateway monitors system response times and access request volumes, then dynamically modifies flow control thresholds to match actual system capacity, preventing both over-blocking and system crashes.
Solution Approach 2:
The patent implements a feedback mechanism where the gateway continuously monitors system response times and access request statistics, uses this information to evaluate whether the current flow control threshold is appropriate, and adjusts the threshold accordingly. This closed-loop control ensures the flow control strategy adapts to changing system conditions.
2Ease of operation
If a fixed flow-limiting strategy is used, then the implementation is straightforward, but the gateway cannot distinguish between abnormal access patterns and legitimate high-volume requests
Solution Approach 1:
The patent introduces dynamic threshold adjustment based on real-time monitoring of access patterns and system load. The flow control threshold is no longer fixed but adapts to distinguish between legitimate high-volume requests (when system load is low) and abnormal access patterns (when system response time increases), improving discrimination accuracy without complicating implementation.
3Reliability
If flow control is maintained at high levels to prevent system overload, then system stability is improved, but legitimate access requests are blocked and service quality deteriorates
Solution Approach 1:
The patent implements dynamic flow control thresholds that automatically adjust based on system load conditions. When system response time is within acceptable ranges, the threshold allows higher throughput to improve productivity. When system load increases and response time deteriorates, the threshold automatically lowers to protect stability, thus balancing both requirements.
Solution Approach 2:
The gateway continuously monitors system response times and uses this feedback to adjust flow control thresholds. This ensures that flow control levels are optimized in real-time to maintain both system stability and acceptable service quality, preventing both over-blocking and system overload.
