Solution Overview

Problem

Conventional network communication systems face inefficiencies and increased physical constraints as the number of sub-networks and service traffic volume grow, particularly in managing message conversion and packet routing across sub-networks with different architectures, leading to reduced throughput and resource overhead.

Innovation Solution

A network control device and method that includes a relay service efficiency promoting section with a service registry and message transfer mechanism, featuring a virtual machine for executing portable code and loading protocol-dependent service proxies, which reduces physical constraints by optimizing message relay and response processing across sub-networks with different architectures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If sequential message conversion is conducted through multiple gateways to connect sub-networks with different architectures, then service linkage between sub-networks is enabled, but processing overhead increases and network throughput decreases

Engineering Contradiction:

Improveservice linkage capabilityVSAvoidnetwork throughput

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent extracts the message conversion function from distributed gateways and centralizes it in a dedicated message conversion server. This separates the conversion processing from the routing and service execution, allowing specialized optimization of conversion operations and reducing the processing burden on network nodes, thereby improving overall network throughput while maintaining service linkage capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a service directory as an intermediary component that mediates between service requesters and service providers across different sub-networks. The service directory manages service registration, discovery, and binding, enabling efficient service linkage without requiring direct gateway interventions for each service interaction, thus reducing processing overhead and enhancing network productivity

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple gateways are deployed to connect different sub-networks, then service linkage between sub-networks is enabled, but physical constraints and network wiring complexity increase

Engineering Contradiction:

Improveservice linkage capabilityVSAvoidnetwork wiring

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal service directory that can manage services across multiple sub-networks with different architectures through a unified interface. This single universal directory replaces the need for multiple gateway-specific service management systems, simplifying network wiring and reducing physical constraints while maintaining the ability to link services across diverse sub-networks

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses service registration and binding mechanisms that create virtual representations of services in the service directory, allowing services to be accessed across sub-networks without requiring physical gateway connections for each service pair. This virtual copying approach reduces the need for extensive physical wiring and gateway infrastructure

Inventive Principle:

Principle #26Copying

3Adaptability or versatility

If service directories manage message conversion and routing information, then service linkage is enabled, but resource consumption increases

Engineering Contradiction:

Improveservice management capabilityVSAvoidprocessing resource consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements service pre-registration and pre-binding mechanisms where services are registered and bound in advance in the service directory. This preliminary action allows the system to prepare service routing information and conversion parameters beforehand, reducing the need for complex real-time processing when services are actually invoked, thereby lowering resource consumption during service execution while maintaining comprehensive service management capability

Inventive Principle:

Principle #10Preliminary action
