Solution Overview

Problem

Current network capacity management systems face challenges in accurately analyzing and optimizing network topologies due to their generic nature, which can lead to insufficient information and high costs in defining tens of thousands of nodes, links, and interrelationships, making it difficult to meet projected needs and ensure network optimality.

Innovation Solution

A network capacity management system that includes a data repository for topology and service consumption data, a network definition component to generate a detailed network definition, and an optimization component using an evolution engine to process the definition based on predetermined criteria, enabling high-granularity analysis and optimization of network paths and capacity consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a network topology is defined at high granularity with tens of thousands of nodes, links, and interrelationships, then measurement precision and analysis accuracy are improved, but device complexity and cost increase significantly

Engineering Contradiction:
Improvenetwork analysis accuracyVSAvoidtopology definition complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the network topology into hierarchical levels (e.g., core network, access network, edge devices) and processes each segment separately. This allows high-granularity analysis of individual segments without requiring simultaneous processing of the entire tens-of-thousands-node network, thereby maintaining measurement precision while reducing overall system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces temporal dimension by capturing network topology at specific time points and comparing changes over time. This allows the system to analyze high-granularity topology data in manageable time slices, improving analysis accuracy without overwhelming the system with all-time data simultaneously.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If a network topology is defined generically with abstract components, then device complexity is reduced, but measurement precision and available information for optimization decrease

Engineering Contradiction:
Improvetopology definition complexityVSAvoidnetwork analysis accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent applies different levels of detail to different parts of the network topology. Critical segments (e.g., core routing paths, high-traffic areas) are defined with high granularity including detailed node and link attributes, while less critical segments use more abstract representations. This local quality approach ensures measurement precision where needed while maintaining overall system manageability.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If real network data is used for analysis, then measurement precision is improved, but the network must be taken out of service or testing capacity is reduced

Engineering Contradiction:
Improvenetwork data accuracyVSAvoidnetwork service availability
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent creates virtual copies or models of the network topology that replicate the structure and characteristics of the real network. These models can be populated with real network data during maintenance windows or using historical data, allowing high-precision analysis to be performed on the copies without removing the actual network from service. The optimization results are then validated and applied back to the real network.

Inventive Principle:
Principle #26Copying

4Manufacturing precision

If detailed topology data is collected and processed, then optimization accuracy is improved, but loss of time for data collection and processing increases

Engineering Contradiction:
Improveoptimization accuracyVSAvoiddata processing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary processing of topology data by pre-identifying critical paths, high-traffic segments, and potential bottleneck areas during periods when full analysis is not required. This preliminary action creates a focused subset of data that requires less intensive processing during actual optimization events, thereby maintaining high optimization accuracy while reducing real-time data processing time.

Inventive Principle:
Principle #10Preliminary action
