Solution Overview

Problem

Commercial premises often lack network redundancy, leading to WAN connectivity loss when switches fail, especially in areas with critical applications or high traffic, necessitating inefficient resource allocation and maintenance.

Innovation Solution

A network management system (NMS) determines redundancy scores for access points (APs), switches, and sites based on received signal strength indicators (RSSIs) and neighbor relationships, enabling proactive recommendations for optimal AP and switch placement and configuration to enhance redundancy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If network redundancy is increased by adding more switches and APs, then network reliability improves, but device complexity and cost increase

Engineering Contradiction:
Improvenetwork redundancyVSAvoidnetwork configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary analysis of network topology and traffic patterns to determine optimal placement of redundant switches and APs before deployment, using simulation and prediction algorithms to pre-calculate redundancy requirements based on criticality scores and traffic density metrics

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts redundancy parameters such as switch/AP placement, configuration, and activation status based on changing network conditions, traffic patterns, and failure probabilities, optimizing the balance between reliability and complexity through continuous parameter tuning

Inventive Principle:
Principle #35Parameter changes

2Reliability

If network redundancy is increased by deploying more infrastructure, then network reliability improves, but resource allocation efficiency deteriorates

Engineering Contradiction:
Improvenetwork redundancyVSAvoidresource allocation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system implements differentiated redundancy strategies for different network zones based on local traffic patterns and criticality requirements, deploying high redundancy only in high-traffic critical areas while using minimal redundancy in low-traffic areas, optimizing resource allocation through spatially varying quality levels

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system deploys redundancy selectively rather than uniformly across the entire network, applying partial redundancy measures only where critical analysis identifies genuine needs based on traffic density and application criticality, avoiding excessive redundancy deployment in non-critical zones

Inventive Principle:
Principle #16Partial or excessive action

3Measurement precision

If manual network configuration and monitoring is performed, then network control precision improves, but labor time and operational complexity increase

Engineering Contradiction:
Improveredundancy assessment accuracyVSAvoidtime for configuration and monitoring
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system continuously monitors network performance, traffic patterns, and failure events, using this feedback to automatically update redundancy assessments, adjust configurations, and optimize resource allocation without manual intervention, creating a closed-loop control system that maintains precision while eliminating time-consuming manual operations

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-configuration and self-monitoring of network redundancy by automatically analyzing topology data, calculating criticality scores, determining optimal placements, and adjusting configurations based on observed network conditions, eliminating the need for manual assessment and reducing operational time

Inventive Principle:
Principle #25Self-service
