Solution Overview

Problem

Existing routing technologies struggle to meet the requirements for flexible traffic path adjustment and optimization, especially in complex 5G network applications, due to the need for manual configuration and high operational complexity.

Innovation Solution

A traffic message forwarding method that involves receiving a traffic message with a block resource identifier, determining a target block resource using filtering rule information from a border gateway controller, and forwarding the message using the target block resource, thereby enabling flexible network resource segmentation and traffic path optimization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual configuration of routing table entries with traffic policy information is implemented for each device, then traffic path adjustment capability is improved, but device complexity and operational complexity increase significantly

Engineering Contradiction:

Improvetraffic path adjustment capabilityVSAvoidoperational complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A network controller is introduced as an intermediary device that centrally manages routing table entries and traffic policy information. The controller automatically generates and distributes routing configurations to multiple network devices, eliminating the need for manual configuration at each device while maintaining flexible traffic path adjustment capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The network controller serves multiple functions including generating routing table entries, managing traffic policy information, and distributing configurations to various network devices. This centralized multi-functional approach replaces the need for individual manual configurations at each device, reducing operational complexity while maintaining adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If routing table entries include detailed traffic policy information for each device, then traffic classification capability is improved, but manual configuration workload increases

Engineering Contradiction:

Improvetraffic classification capabilityVSAvoidconfiguration efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The network controller performs preliminary actions by pre-generating and validating routing table entries with traffic policy information before distributing them to network devices. This centralized preparation work is done once at the controller level, eliminating the need for repeated manual configuration at each device and significantly improving configuration efficiency while maintaining traffic classification capability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The network controller acts as an intermediary that automates the creation and distribution of routing configurations. It generates routing table entries with traffic policy information centrally and automatically pushes them to relevant devices, replacing manual configuration workflows and improving productivity while preserving detailed traffic classification capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If conventional routing technology is used with basic prefix mask information, then device simplicity is maintained, but flexible scheduling and massive connections required for 5G cannot be achieved

Engineering Contradiction:

Improverouting table simplicityVSAvoid5G network flexibility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The routing functionality is segmented into two parts: basic prefix mask information stored in simple routing tables at network devices, and detailed traffic policy information managed centrally by the network controller. This segmentation allows devices to maintain simplicity while the system as a whole achieves the flexibility required for 5G networks through centralized policy management.

Inventive Principle:

Principle #1Segmentation
