1Extent of automation
If manual operation or irregular log monitoring is used to determine connection failures, then the system can operate without additional monitoring hardware, but the determination process becomes time-consuming and ineffective
Solution Approach 1:
The system performs preliminary actions by continuously measuring time delays and pre-processing connection status information before failures occur. The time delay measurement unit constantly monitors network responses, and the system maintains ready-to-use connection status data, enabling immediate failure detection without waiting for manual checks or log reviews.
Solution Approach 2:
The system implements feedback mechanisms where the time delay measurement unit continuously monitors network connection responses and feeds this information back to the connection failure determination unit. This closed-loop feedback enables automatic, real-time detection of connection failures based on measured time delays compared against threshold values.
2Reliability
If manual monitoring is performed to detect connection failures, then the system structure remains simple, but the monitoring effectiveness and response time deteriorate
Solution Approach 1:
The system performs self-service by automatically detecting and determining connection failures without requiring external manual intervention. The time delay measurement unit and connection failure determination unit work autonomously to monitor network status, measure delays, and identify failures, making the system self-diagnosing and reducing dependency on human operators.
Solution Approach 2:
The patent replaces manual mechanical monitoring processes with automated electronic measurement and determination systems. The time delay measurement unit uses electronic timing mechanisms to measure network response times, and the connection failure determination unit uses automated logic to compare measurements against thresholds, substituting human manual checks with electronic automation.
3Productivity
If irregular determination methods are used, then the system requires minimal additional components, but the detection timeliness and effectiveness worsen
Solution Approach 1:
The system detects connection failures by measuring changes in time delay parameters. The time delay measurement unit continuously monitors network response time as a critical parameter, and the connection failure determination unit detects failures when time delay exceeds predetermined threshold values, enabling efficient detection through parameter monitoring rather than complex diagnostic procedures.
