Solution Overview

Problem

Conventional network taps lack storage capability and efficient data management, making it difficult to analyze and resolve issues related to 'bad' data packets, and they are unable to maintain network links during power disruptions, leading to potential financial losses.

Innovation Solution

A time machine device is introduced, equipped with a pre-processing module, processors, storage memory, and an export component, capable of capturing, filtering, encrypting, and storing data packets, and maintaining network links through zero-delay arrangements, allowing for efficient data analysis and minimizing disruptions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If network taps are configured as bypass devices without storage capability, then data packets can flow through the network environment, but the network tap is unable to provide useful information when problems arise with 'bad' data packets

Engineering Contradiction:
Improvenetwork monitoring reliabilityVSAvoiddata packet information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The network tap performs preliminary action by capturing and storing data packets before they are forwarded through the network. The storage component saves copies of data packets at the time they pass through the tap, enabling later retrieval and analysis when problems occur, thus preventing information loss while maintaining normal network flow.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If network taps do not have storage capability, then the device complexity remains low, but the ability to analyze and resolve issues related to 'bad' data packets is compromised

Engineering Contradiction:
Improvenetwork tap structureVSAvoiddata packet analysis capability
Core Design Contradiction:
Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The invention extracts the storage functionality from the traditional network tap design by adding a dedicated storage component that operates independently. This allows the tap to maintain its simple bypass structure while simultaneously capturing data packets for later analysis, separating the monitoring function from the storage function to minimize complexity increase.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If conventional network taps are used without storage, then data traffic can pass through efficiently, but financial losses may occur due to inability to maintain network links during power disruptions

Engineering Contradiction:
Improvedata traffic throughputVSAvoidnetwork link stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The network tap incorporates a storage component that acts as a cushion during power disruptions. When power is lost, the stored data packets can be used to maintain network link functionality or provide backup information, preventing financial losses from link failures while continuing to allow data traffic to pass through during normal operation.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
