Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Routers with Internet line automatic detection functions often fail to connect to the Internet, making it difficult for users to diagnose the reason for failure, as the inquiry destination cannot reproduce the router's state and installation environment, and lacks necessary logs for investigation.
Innovation Solution
A network device with processing circuitry that detects connection availability for multiple types of connections and generates a detection code indicating the results, allowing for efficient communication failure information provision, including parallel detection processing for IPv4 and IPv6 connections, and aggregation of interval detection codes into a detection code for transmission to a server.

Engineering Contradiction Analysis
1Extent of automation
If automatic detection function is implemented, then connection setup is automated, but diagnostic information for failure analysis is lost
Solution Approach 1:
The system performs detection processing and generates detection codes before connection establishment fails or during the connection process. By capturing connection state information in advance (during detection processing), the system preserves diagnostic data that would otherwise be lost when automatic connection setup fails, enabling later analysis of what went wrong.
Solution Approach 2:
The system creates a copy of the connection state information in the form of detection codes that represent the router's state and installation environment. These detection codes serve as informational copies that can be transmitted to inquiry destinations for analysis, preserving diagnostic data without interfering with the automatic connection process.
2Reliability
If multiple connection types are detected, then connection reliability improves, but processing complexity increases
Solution Approach 1:
The detection processing is divided into separate parallel processes for different connection types (IPv4 and IPv6). Each connection type is detected independently through separate detection processing paths, allowing the system to handle multiple connection types without creating a monolithic complex processing structure. This segmentation maintains reliability while managing complexity through modular detection routines.
Solution Approach 2:
The detection code generation mechanism serves multiple functions: it captures connection state information, represents installation environment details, and provides diagnostic data for various connection types. By creating a universal detection code structure that can represent multiple connection scenarios, the system handles diverse connection types through a unified approach, reducing overall processing complexity.
