Dynamic Timeout Tuning in Payment Processing Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Payment transaction processing systems face issues with expired timeout periods due to network errors or latency, leading to duplicate payments, increased network traffic, and unproductive resource consumption, particularly during peak periods like Black Friday.
Innovation Solution
Implementing a system that monitors and dynamically adjusts timeout periods within payment transaction processing systems to prevent duplicate payments and reduce resource consumption by stopping processing and rolling back transactions when a timeout is imminent, and adjusting element timeout periods based on remaining transaction time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If timeout periods are extended to allow more processing time, then transaction processing completeness improves, but resource consumption and duplicate payment risks increase
Solution Approach 1:
The patent implements dynamic timeout adjustment where the timeout period is not fixed but adapts based on real-time system conditions. The timeout monitoring service continuously evaluates system state and adjusts timeout values dynamically, allowing the system to extend timeouts when resources are available and reduce them when resources are constrained, thus resolving the contradiction between processing completeness and resource consumption
Solution Approach 2:
The system employs feedback mechanisms through timeout monitoring services that track both the timeout status and system resource conditions. This feedback loop enables the system to learn from past timeout events and adjust future timeout periods accordingly, improving transaction completeness while preventing excessive resource consumption from prolonged processing of timed-out transactions
2Loss of energy
If timeout periods are reduced to prevent duplicate payments, then resource consumption decreases, but transaction processing reliability deteriorates
Solution Approach 1:
The system performs preliminary actions by proactively monitoring timeout periods and detecting potential timeout conditions before they occur. The timeout monitoring service identifies transactions at risk of timing out and takes preventive measures such as extending timeouts or rolling back partial processing, thereby preventing duplicate payments while maintaining adequate processing time for legitimate transactions
3Reliability
If continuous monitoring and dynamic adjustment of timeout periods is implemented, then transaction processing reliability improves, but system complexity increases
Solution Approach 1:
The timeout monitoring service operates autonomously, self-managing the complexity of continuous monitoring and dynamic timeout adjustment without requiring extensive external control systems. The service independently tracks timeout periods, evaluates system conditions, and adjusts timeouts or triggers rollbacks automatically, thereby improving reliability while containing system complexity through self-service automation

AI summary
Various embodiments herein each include at least one of systems, methods, software, and data structures that track timeout periods with regard to data processing requests, dynamically tune timeout periods within payment transaction processing systems, directly and indirectly decrease unproductive consumption of transaction processing resources, avoid situations giving rise to duplicate payments for a single purchase, and decrease transaction processing timeouts. Some such embodiments include monitoring a timeout period within a payment transaction processing system to stop processing and return a timeout error when a transaction timeout period is about or has expired while also stopping processing of the transaction and rolling back any portions of processing of the payment request that may have already been performed.
