Data Communication Address Conversion Without Encapsulation

Solution Overview

Problem

Conventional data communication systems incur increased communication and processing loads due to encapsulation of data with header information, which complicates route selection and address changes.

Innovation Solution

A data communication system utilizing first and second communication nodes with conversion processing units to convert sending source and destination addresses without encapsulating data, enabling bi-directional communication while hiding route selection and address changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If data is encapsulated with header information for route selection and address changes, then communication routing is enabled, but communication load and processing load increase

Engineering Contradiction:

Improveroute selection capabilityVSAvoidcommunication load

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The patent extracts the address conversion function from the data encapsulation process. Instead of encapsulating data with header information containing source and destination addresses, the system separately performs address conversion at communication nodes. This removes the harmful header overhead while preserving the routing capability, directly resolving the contradiction between route selection and communication load.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces communication nodes (first communication node and second communication node) as intermediaries that perform address conversion. These nodes act as mediators between the data transmission process and the routing requirements, converting addresses without requiring data encapsulation. This intermediary mechanism enables routing while avoiding the communication load increase associated with encapsulation.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A data communication system includes: a first communication node having communication interfaces for sending data to a target node via one communication interface; and a second communication node for sending the data to the first communication node, with the one communication interface as a sending destination. The first communication node has a first conversion processing unit that converts a sending source address of the data to be sent to the target node into an address of the second communication node. The second communication node has a second conversion processing unit that converts a sending destination address of the data received from the target node into an address of the one communication interface.
