Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As communication networks grow in size, speed, and complexity, diagnosing and resolving issues such as inefficient data transmission, incorrect routing, and excessive network traffic becomes increasingly difficult due to the dynamic nature of network configurations and the introduction of new protocols and devices.
Innovation Solution
A network diagnostic device is placed in-line between nodes to capture the timing values of speed negotiation signals, measuring and comparing the duration of data units against desired values, generating records that can be displayed to users for diagnostic purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network speed and data transmission rate are increased to meet growing bandwidth demand, then network capacity and productivity are improved, but network complexity and difficulty of diagnosing problems increase
Solution Approach 1:
The patent introduces an intermediary diagnostic device that captures and measures timing values of speed negotiation signals between network nodes. This mediator enables precise measurement of RCDT and SNTT parameters without disrupting the high-speed data transmission, allowing diagnostics in complex high-bandwidth networks.
2Reliability
If network diagnostic capabilities are enhanced to improve reliability, then problem detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent extracts only the essential timing information (RCDT and SNTT values) from the speed negotiation signals for diagnostic purposes. By focusing on these specific extracted parameters rather than analyzing entire signal streams, the device achieves reliable diagnostics with reduced complexity.
Solution Approach 2:
The patent replaces complex mechanical or software-based diagnostic methods with direct electrical measurement of timing signals. By using hardware timers to capture RCDT and SNTT values directly from the signal lines, the system achieves high reliability without complex processing logic.
3Measurement precision
If speed negotiation timing is precisely measured to diagnose transmission issues, then measurement precision is improved, but the diagnostic device complexity increases
Solution Approach 1:
The patent uses preliminary action by capturing timing values during the speed negotiation phase before actual high-speed data transmission begins. The diagnostic device measures RCDT and SNTT timing parameters during this initial negotiation window, establishing precise baseline measurements without interfering with subsequent data transmission.

AI summary
Systems and methods for a network diagnostic device or component that is placed in-line between two nodes in a network to capture the value of a component of a speed negotiation signal. The network diagnostic component receives a speed negotiation signal from a first node for communication with a second node. The speed negotiation signal may be received by a receive module. The speed negotiation signal includes one at least a first portion that comprises one or more data units. The network diagnostic component measures the duration of the data units of the first component of the speed negotiation data. This measurement may be performed by a measurement module. The network diagnostic component compares the measured duration with a desired duration. The comparison may be performed by a measurement module. A record of whether the measured duration compares with the desired duration is then generated by a generation module.
