Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual testing of network communication components to identify errors is labor-intensive and inefficient, requiring technical knowledge and skill, and existing automated methods still necessitate manual effort to determine the source of errors.
Innovation Solution
A device and method that automatically monitor communications between network devices for errors, using loopback tests to identify the source of errors by comparing error metrics with thresholds and applying local or remote loopback tests to determine if NICs, transceiver components, or transmission lines are causing the issues.

1Measurement precision
If manual testing methods are used to identify error sources in network communications, then technical expertise and manual effort can be applied to diagnose problems, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The system performs self-diagnosis by automatically executing loopback tests and analyzing error metrics without requiring external manual intervention. The device monitors its own communication channels, detects errors, and identifies error sources autonomously, eliminating the need for manual testing while maintaining high diagnostic accuracy
Solution Approach 2:
The system pre-configures multiple loopback test mechanisms at different locations (local and remote) and pre-establishes error metric thresholds. When an error occurs, these pre-positioned test points enable immediate automated diagnosis without requiring manual setup, significantly reducing identification time while maintaining precision
2Productivity
If automated error detection is implemented, then testing speed increases, but the system complexity increases due to multiple test mechanisms and metrics
Solution Approach 1:
The diagnostic system is segmented into distinct functional components: local loopback test mechanisms at the first device, remote loopback test mechanisms at the second device, error metric collection modules, and analysis modules. Each segment operates independently but contributes to the overall automated diagnosis, enabling high-speed error detection while managing complexity through modular architecture
Solution Approach 2:
The loopback test mechanisms serve multiple functions: they test transmission lines, test NICs, test transceiver components, and establish baseline error metrics. This multi-functionality reduces the need for separate specialized test equipment, increasing productivity while controlling system complexity through versatile reusable components
3Measurement precision
If multiple loopback test mechanisms are deployed at different locations, then error source identification accuracy improves, but the quantity of components and system complexity increase
Solution Approach 1:
The system combines local loopback test capabilities at the first device with remote loopback test capabilities at the second device into a unified automated diagnostic framework. Error metrics from both locations are merged and analyzed together to precisely identify error sources, achieving high location accuracy while reducing the total number of mechanisms compared to having completely separate independent test systems
