Solution Overview

Problem

The existing methods for managing overlay and underlay networks in data centers are inefficient, leading to increased Mean-Time-To-Repair (MTTR) and performance degradation due to the lack of effective coordination and management tools, causing inconvenience during troubleshooting and repair processes.

Innovation Solution

A computer-implemented method and system that correlates control information from underlay and overlay networks to generate a relationship matrix, determining issues and performing corrective actions to improve network management, leveraging real-time monitoring tools and historical data for end-to-end visibility without requiring separate provisioning and management tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate vendor tools are used to manage overlay and underlay networks, then each network can be managed independently, but troubleshooting and repair processes become inefficient and time-consuming

Engineering Contradiction:
ImproveIndependent network management capabilityVSAvoidMean-Time-To-Repair (MTTR)
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent combines separate overlay and underlay network management into a unified management system that correlates control information from both networks. This integration allows simultaneous visibility and control of both network layers, enabling efficient troubleshooting by identifying root causes across network boundaries and reducing MTTR while preserving independent management capabilities through virtualized control planes.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If overlay network is built on top of underlay network with virtual links, then network flexibility and adaptability improve, but correlation and coordination between networks become complex

Engineering Contradiction:
ImproveNetwork flexibilityVSAvoidManagement complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a correlation engine as an intermediary component that sits between overlay and underlay network management functions. This mediator correlates control information from both networks, maps virtual links to physical infrastructure, and provides unified visibility without adding significant complexity to the existing network architecture, thereby maintaining flexibility while simplifying management.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If traditional network management tools are used without correlation capabilities, then implementation is simple, but troubleshooting efficiency and repair coordination deteriorate

Engineering Contradiction:
ImproveImplementation simplicityVSAvoidTroubleshooting efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent implements preliminary correlation of control information from overlay and underlay networks before troubleshooting is needed. By pre-establishing relationships between virtual and physical network elements and maintaining correlated state information, the system prepares troubleshooting data in advance, enabling rapid diagnosis and repair coordination when issues occur without requiring complex real-time analysis.

Inventive Principle:
Principle #10Preliminary action
