Automatic Media Converter Link Status Propagation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media converter installations fail to propagate 'link down' status effectively across different data communication channels, leading to inadequate network reconfiguration and human intervention requirements, which are non-compliant with IEEE standards and cumbersome.
Innovation Solution
A method and apparatus that determine the link status of first and second data communication channels and automatically force the link status of one channel to 'link down' when the other channel is down, using a processor and physical layer devices with registers to manage link status bits and propagate errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are added to detect link down status and propagate it across channels, then link status propagation is improved, but compliance with network standards deteriorates
Solution Approach 1:
The media converter automatically detects link status changes on one channel and autonomously propagates this status to other channels without requiring external sensors or manual intervention. The system self-manages link status propagation by monitoring its own channels and automatically updating link status bits in registers, eliminating the need for separate sensing mechanisms while maintaining standard compliance.
2Reliability
If manual control is provided on each switch to force link up, then link status control is improved, but ease of operation deteriorates due to human intervention requirements
Solution Approach 1:
The media converter automatically forces link status down on one channel when the other channel goes down, eliminating the need for manual intervention. The system autonomously maintains link status consistency across all channels by automatically detecting changes and propagating them, replacing the cumbersome manual control process with automated system-wide coordination.
Solution Approach 2:
The system continuously monitors link status on all channels and uses this feedback to automatically adjust link status bits in registers. When a link goes down, the system detects this change and automatically propagates the status update to other channels, creating a closed-loop feedback mechanism that maintains link integrity without manual intervention.
3Measurement precision
If link status is manually propagated across channels, then link status accuracy is improved, but productivity deteriorates due to cumbersome reestablishment process
Solution Approach 1:
The media converter automatically propagates link status changes across all channels without requiring manual operations. The system self-updates link status bits in registers and automatically notifies other devices of link status changes, dramatically accelerating the network reconfiguration process while maintaining accurate link status information.
Solution Approach 2:
The system pre-configures automatic propagation mechanisms in place before link failures occur. Link status detection and propagation pathways are established in advance through the media converter's automatic monitoring and registration systems, enabling immediate automated response when link failures happen without requiring manual intervention or pre-step-by-step reconfiguration.

AI summary
An apparatus, method, and computer-readable media for controlling the link status of first and second data communication channels. The apparatus comprises a first physical layer device coupled to the first channel, the first physical layer device comprising a first register storing a first link status bit that indicates the link status of the first channel; and a second physical layer device coupled to the second channel, the second physical layer device comprising a second register storing a second link status bit that indicates the link status of the second channel; wherein the first and second physical layer devices are configured to pass data between the first and second channels; and a processor to (a) determine the link to status of the first channel; (b) when the link status of the first channel determined at (a) is link up, determine the link status of the second channel; and (c) when the link status of the second channel determined at (b) is link down, automatically force the link status of the first channel to link down.
