Wired Network Connection Status Verification via Link Pulse Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wired networks fail to accurately determine the connection status, particularly under 1 Gbps mode, due to incorrect coupling of connection ends, leading to failed data transmission attempts and persistent attempts to establish an unachievable communication mode.
Innovation Solution
A method involving the use of link pulses and idle patterns transmitted through multiple connection ends to confirm correct coupling and adjust communication modes to 10 Mbps or 100 Mbps if 1 Gbps mode requirements are not met, disabling the 1 Gbps mode and re-establishing connectivity through correct coupling verification.

Engineering Contradiction Analysis
1Speed
If 1 Gbps mode is attempted without verifying correct coupling of all four twist pairs, then communication speed is improved, but connection reliability deteriorates due to failed data transmission
Solution Approach 1:
The patent applies preliminary action by performing coupling verification through link pulse transmission before attempting 1 Gbps communication. The system transmits link pulses through all four twist pairs to confirm correct physical connection, and only after successful verification does it enable 1 Gbps mode. This prevents unreliable high-speed communication by ensuring proper coupling beforehand.
2Measurement precision
If link pulse transmission is performed through all connection ends, then connection status detection accuracy is improved, but communication establishment time increases
Solution Approach 1:
The patent applies segmentation by dividing the connection verification process into separate phases: first transmitting link pulses through individual connection ends to detect coupling status, then based on the detection results, selectively establishing communication paths. This segmented approach ensures accurate detection of connection status while optimizing the subsequent communication setup time.
3Speed
If the system continuously attempts to establish 1 Gbps mode without detecting incorrect coupling, then communication speed is maintained, but energy consumption increases due to persistent failed attempts
Solution Approach 1:
The patent applies feedback by using the results of link pulse transmission and idle pattern detection to determine whether to continue attempting 1 Gbps mode or switch to lower speeds. When coupling is detected as incorrect, the system receives feedback to stop further 1 Gbps attempts and automatically reduces communication speed, thereby eliminating wasteful energy consumption from persistent failed communication attempts.

AI summary
A method applied to a wired network including a first network device and a second network device is disclosed. The first and second network devices each include a first set of connection ends and a second set of connection ends. Firstly, the first network device transmits a specific signal pattern through its first set and second set of connection ends. Then, the first network device detects whether a signal is received at its first set and second set of connection ends. If it is determined that a signal is not received at the first set connection ends while a signal is received at the second set connection ends, the first network device determines that its second set of connection ends is not correctly coupled to the second set of connection ends of the second network device.
