Solution Overview

Problem

Existing network integration systems face IP address conflicts when new networks or devices are added, leading to disruptions and management challenges in commercial and residential environments.

Innovation Solution

A method and system that dynamically assigns new IP addresses to new network components using router information protocol (RIP) and open shortest path first protocol (OSPF) messages, prioritizing existing IP addresses and resolving conflicts by reassigning addresses based on a multi-tiered prioritization scale to ensure seamless integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If new networks or devices are added to existing networks, then network functionality and device connectivity are improved, but IP address conflicts occur causing network disruptions

Engineering Contradiction:
Improvenetwork integration capabilityVSAvoidnetwork stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary detection of IP addresses in the existing network before new devices are integrated. By proactively identifying and reserving available IP addresses in advance, the system prevents conflicts before they occur, allowing seamless network expansion while maintaining stability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the network for IP address assignments and detects when new devices are added. This feedback mechanism enables real-time identification of potential conflicts and automatic resolution through dynamic IP address reassignment, ensuring network reliability during integration

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If IP addresses are dynamically assigned to new devices, then network adaptability is improved, but complexity of IP address management increases

Engineering Contradiction:
Improvedevice integration flexibilityVSAvoidIP address management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system enables new devices to automatically obtain IP addresses through self-service mechanisms. When a new device joins the network, the system autonomously detects its presence, checks for address conflicts, assigns an appropriate IP address, and integrates the device without requiring manual configuration or complex management intervention

Inventive Principle:
Principle #25Self-service

AI summary

A method for assigning new internet protocol (IP) addresses to new devices in an existing network is provided comprising assigning respective new IP addresses to one or more new network components by a first device based on one or more communications received by the first device, wherein the one or more communications comprise advertisement messages that include information about the one or more new network components. A network system is further provided, the network system comprising a first device adapted to assign respective new internet protocol (IP) addresses to one or more new network components based on one or more communications received by the first device, wherein the one or more communications comprise advertisement messages that include information about the one or more new network components.
