Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing solutions fail to efficiently maintain and distribute up-to-date addressing information for peer networking devices in private networks, particularly in geographically distributed setups, where addressing information is variable and unpredictable.

Innovation Solution

A method involving network devices generating registry request messages with distinct privilege portions, conveying these to a shared contact point network entity, and obtaining responses containing peer contact point information, which is then used to maintain and update local peer contact point tables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If site-to-site VPN deployment is used to establish private networks over public networks, then network connectivity between geographically separated branch locations is achieved, but addressing information becomes variable and unpredictable, making configuration complicated

Engineering Contradiction:

Improvenetwork connectivityVSAvoidconfiguration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a centralized network management system that acts as an intermediary between networking devices and the public network infrastructure. This system automatically obtains, manages, and distributes addressing information to all networking devices in the private network, eliminating the need for manual configuration and resolving the complexity caused by variable addressing information from ISPs

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The networking devices are configured to automatically request and update their addressing information from the centralized management system without human intervention. The devices self-configure by receiving addressing information through automated communication protocols, reducing configuration complexity while maintaining adaptability to changing network conditions

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If addressing information is obtained from Internet service providers, then network devices can establish connections over public networks, but the addressing information is unpredictable and inconsistent, requiring frequent updates and manual intervention

Engineering Contradiction:

Improvenetwork accessibilityVSAvoidtime for addressing information updates

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The centralized network management system continuously monitors and maintains addressing information for all networking devices, ensuring continuous availability of current addressing data. The system proactively pushes updates to devices when addressing information changes, eliminating gaps and manual intervention delays

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system implements a feedback mechanism where networking devices automatically report their status and requesting updated addressing information when needed. The centralized management system responds by providing current addressing data, creating a continuous feedback loop that ensures devices always have accurate information without manual intervention

Inventive Principle:

Principle #23Feedback

3Ease of manufacture

If manual configuration of networking devices is performed, then initial network setup is possible, but maintaining current addressing information becomes inefficient and error-prone

Engineering Contradiction:

Improveinitial setup capabilityVSAvoidefficiency of maintaining addressing information

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The centralized network management system pre-obtains and stores addressing information for all networking devices before they need to communicate. This preliminary action ensures that when devices are deployed or need to establish connections, the addressing information is already available and configured, eliminating the need for manual setup and ongoing maintenance

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent merges the addressing information management function into a centralized system that handles all devices uniformly. Instead of manually configuring each device separately, the centralized system consolidates the management of addressing information for the entire network, improving efficiency and reducing errors through automated, standardized processes

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Previous solutions to the problem of maintaining up-to-date network device addressing, fail to provide systems or processes that efficiently share and obtain addressing information of networking devices in a given network. By contrast, and to that end, various implementations disclosed herein include systems, methods and apparatuses that generate a registry request message, where the registry request message includes a first portion characterized by a first write privilege and a second portion characterized by a second write privilege different from the first write privilege. The systems, methods and apparatuses convey the registry request message to a shared contact point network entity, and obtain a response message addressed from the shared contact point network entity, where the response message includes peer addressing information corresponding to one or more peer network devices associated with the aforementioned systems, methods and apparatuses.
