Solution Overview

Problem

The configuration of management IP addresses in communications networks, particularly with the transition from IPv4 to IPv6, increases network operation and maintenance costs due to the complexity of managing multiple IP address types and the need for manual intervention by network administrators.

Innovation Solution

A method and system that automatically determine and manage management IP addresses by exchanging information between systems, using protocols like PPPoE, to enable efficient configuration and switching of IP addresses, reducing the need for manual intervention and enhancing network reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual configuration of management IP addresses is used, then network administrators can precisely control IP address assignment, but network operation and maintenance costs increase due to manual intervention requirements

Engineering Contradiction:

ImproveIP address assignment controlVSAvoidnetwork operation and maintenance efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent implements automatic IP address configuration where the network management system autonomously discovers, assigns, and manages IP addresses for network elements without manual intervention. The system self-configures by receiving identification information from network elements, determining appropriate IP addresses based on pre-configured policies, and automatically updating management databases, thereby eliminating manual configuration while maintaining precise control

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent pre-configures IP address assignment policies, address pools, and allocation rules in the network management system before actual network element deployment. This preliminary configuration enables automatic IP assignment when network elements join the network, eliminating the need for manual real-time configuration while ensuring consistent and controlled IP address management

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If multiple IP address types (IPv4 and IPv6) are supported, then network adaptability improves, but system complexity increases due to managing multiple address types

Engineering Contradiction:

ImproveIP protocol compatibilityVSAvoidIP address management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs the network management system with multi-functional IP address management capabilities that handle both IPv4 and IPv6 protocols through a unified framework. The system universally supports multiple IP address types by maintaining separate but parallel management mechanisms for each protocol type, allowing it to adapt to different IP versions without requiring separate management systems or significantly increasing operational complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the IP address management system into protocol-specific modules that independently handle IPv4 and IPv6 address assignment and management. This segmentation allows each protocol type to be managed through dedicated procedures and policies while maintaining a unified overall management architecture, reducing the complexity of managing multiple IP address types by isolating protocol-specific logic

Inventive Principle:

Principle #1Segmentation

3Productivity

If automatic IP address determination is implemented, then configuration efficiency improves, but reliability may decrease due to automated decision-making without manual verification

Engineering Contradiction:

Improveconfiguration efficiencyVSAvoidIP address assignment accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where the network management system continuously monitors the status and performance of automatically assigned IP addresses. The system collects information about IP address usage, network element performance, and assignment correctness, then uses this feedback to refine and adjust its automatic IP assignment algorithms, ensuring high reliability while maintaining configuration efficiency

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent incorporates validation and verification procedures that run automatically as part of the IP address assignment process. Before finalizing IP address assignments, the system performs checks to ensure correctness, and maintains backup assignment options. This beforehand cushioning ensures that automatic IP determination maintains high reliability by preventing erroneous assignments before they can cause problems

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A method includes a second system that determines a type of a first management Internet Protocol (IP) address, and sends, to a first system, first information used to indicate the type of the first management IP address; the first system determines the first management IP address based on the type of the first management IP address indicated by the first information, and releases a first correspondence between system identification information and the first management IP address to an advertisement system; the advertisement system sends the first correspondence to a network management system; and the network management system manages the first system based on the first correspondence.
