Solution Overview

Problem

Conventional network switch devices face challenges in efficiently monitoring and handling network anomalies, such as optical fiber insertion/extraction anomalies and signal anomalies, due to high processing resource consumption and limitations in pin availability between the switch device and the packet transceiving module.

Innovation Solution

A network switch device with optical fiber data transceivers generating interrupt control signals, a logic unit combining these signals into an interrupt combined signal, and a processing unit determining anomalies only when the logic level of the combined signal changes, allowing for reduced processing load and real-time handling of anomalies using an interrupt handler.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the network switch device proactively monitors network anomaly events by checking changes in interrupt signal pins, then network anomaly detection capability is improved, but processing resources are consumed and processing load is raised

Engineering Contradiction:
Improvenetwork anomaly detection capabilityVSAvoidprocessing load
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent combines multiple interrupt control signals from different optical fiber data transceivers into a single interrupt combined signal through a logic unit. This merging approach allows the processing unit to monitor multiple transceivers through one consolidated signal, reducing the number of pins required and decreasing processing load while maintaining comprehensive anomaly detection capability across all transceivers

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the monitoring function by separating signal combination logic from anomaly determination logic. The logic unit handles signal combination while the processing unit handles anomaly determination only when triggered. This segmentation allows proactive monitoring to be implemented without continuously consuming processing resources, as the processing unit is activated only when the interrupt combined signal indicates a potential anomaly

Inventive Principle:
Principle #1Segmentation

2Productivity

If the network switch device passively receives notifications from the packet transceiving module, then processing resources are saved, but the device is limited by pin availability between the switch device and the packet transceiving module

Engineering Contradiction:
Improveprocessing resource consumptionVSAvoidpin availability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent merges multiple interrupt control signals from multiple optical fiber data transceivers into a single interrupt combined signal. This consolidation reduces the number of pins required on the processing unit, thereby increasing pin availability and adaptability while still enabling monitoring of multiple transceivers

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a logic unit as an intermediary between the optical fiber data transceivers and the processing unit. This logic unit combines multiple interrupt signals before they reach the processing unit, serving as a mediator that reduces pin requirements while maintaining the ability to monitor all transceivers effectively

Inventive Principle:
Principle #24Intermediary (Mediator)

3Speed

If the processing unit constantly determines whether each optical fiber data transceiver becomes anomalous, then real-time monitoring is achieved, but processing load increases significantly

Engineering Contradiction:
Improveanomaly detection speedVSAvoidprocessing load
Core Design Contradiction:
SpeedVSProductivity

Solution Approach 1:

The patent implements periodic action by having the processing unit determine whether anomalies occur only when the interrupt combined signal changes logic level, rather than continuously monitoring each transceiver. This event-driven approach maintains real-time anomaly detection capability while significantly reducing processing load, as the processing unit is activated only when necessary

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent uses feedback through the interrupt combined signal to trigger processing unit actions. The logic unit continuously monitors transceiver status and provides feedback to the processing unit only when changes occur. This feedback mechanism enables real-time anomaly detection while optimizing processing resource usage by activating the processing unit only when the feedback signal indicates a potential issue

Inventive Principle:
Principle #23Feedback
