Solution Overview

Problem

Current tunnel communication systems rely on heuristic algorithms for IP address allocation, such as DHCP and AutoIP, which are complex and time-consuming, limiting the number of addresses that can be allocated within a predetermined range.

Innovation Solution

An information-processing device equipped with a tunnel communication part, an identifier acceptor, an identifier storage part, and an address determination part that uses communication destination and source device identifiers to determine IP addresses for communication target data, eliminating the need for DHCP or AutoIP and allowing for a simpler and more efficient address allocation process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If DHCP or AutoIP heuristic algorithms are used for IP address allocation, then address allocation can be performed, but the system becomes complex and time-consuming

Engineering Contradiction:

Improveaddress allocation speedVSAvoidaddress allocation algorithm complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts the address allocation function from the complex DHCP/ AutoIP heuristic algorithms and implements it through a simple deterministic calculation based on device identifiers. The address determination part calculates the IP address directly from the communication destination device identifier and communication source device identifier, eliminating the need for complex heuristic search processes.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs self-service address allocation where each device independently determines its own IP address based on its device identifier and the identifier of the communication partner. This eliminates the need for a central DHCP server and complex coordination algorithms, allowing devices to autonomously allocate addresses through simple deterministic calculation.

Inventive Principle:

Principle #25Self-service

2Loss of time

If heuristic algorithms like AutoIP are used, then address allocation is possible, but it takes a long time to determine an IP address

Engineering Contradiction:

Improvetime to determine IP addressVSAvoidaddress determination simplicity

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The patent applies preliminary action by pre-establishing a deterministic relationship between device identifiers and IP addresses. Instead of performing iterative search operations during address allocation, the system pre-defines that the IP address can be directly calculated from the device identifiers, eliminating the need for time-consuming heuristic inquiries and trials.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical iterative search process of heuristic algorithms with a direct mathematical calculation. Instead of repeatedly inquiring whether an address is available and adjusting based on conflicts, the system substitutes this complex process with a straightforward deterministic formula that computes the IP address directly from the device identifiers.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If a predetermined address range is used for allocation, then address allocation is constrained, but the device cannot allocate too many addresses to exceed the range

Engineering Contradiction:

Improveaddress allocation flexibilityVSAvoidnumber of allocatable addresses

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent transitions from a one-dimensional constrained address range to a two-dimensional address space defined by device identifier pairs. Instead of being limited to a predetermined IP address range, the system generates addresses based on the combination of communication source and destination device identifiers, effectively expanding the address allocation capacity beyond fixed ranges.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
