Solution Overview

Problem

Existing communication systems fail to seamlessly interwork services between wired and wireless terminals using conventional communication networks, limiting the ability to share internet services across different devices.

Innovation Solution

A mirroring apparatus with an IP address sniffing module, an IP address converting module, and a routing module that monitors and duplicates internet packets, changing the destination IP address to enable service mirroring between terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional communication networks are used without mirroring apparatus, then network structure remains simple, but service interworking between wired and wireless terminals cannot be achieved

Engineering Contradiction:

Improveservice interworking capabilityVSAvoidnetwork structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A mirroring server is introduced as an intermediary component in the communication network. The server includes an IP address sniffing module to monitor packets, an IP address converting module to duplicate and modify packets, and a routing module to distribute packets to multiple terminals. This intermediary enables service interworking between wired and wireless terminals without fundamentally altering the existing network infrastructure.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If IP address converting module duplicates packets for multiple terminals, then service sharing capability is improved, but network traffic volume increases

Engineering Contradiction:

Improveservice sharing capabilityVSAvoidnetwork traffic volume

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The IP address converting module creates duplicate copies of incoming packets and redistributes them to multiple destination terminals. This copying mechanism enables a single service stream to be shared across multiple wired and wireless terminals simultaneously, achieving service interworking through packet duplication rather than complex protocol translation.

Inventive Principle:

Principle #26Copying

3Speed

If real-time packet monitoring and duplication is performed, then service mirroring speed is improved, but processing time and system load increase

Engineering Contradiction:

Improveservice mirroring speedVSAvoidpacket processing time

Core Design Contradiction:

SpeedVSLoss of time

Solution Approach 1:

The mirroring server continuously monitors incoming packets at the network layer and performs real-time duplication and routing operations. By operating continuously at the IP layer rather than applying complex protocol transformations, the system achieves real-time service mirroring with minimal processing delay, maintaining high speed while enabling service sharing.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A mirroring apparatus for providing a mirroring service includes an Internet protocol (IP) address sniffing module for monitoring whether an Internet service provided to a predetermined terminal exists; an IP address converting module for duplicating a packet transmitted to the predetermined terminal according to the Internet service and changing a destination IP address of the duplicated packet to an IP address of other terminals; and a routing module for routing the packet by determining a route of the packet based on the IP address of the packet.
