IPv4 Packet Header Conversion for IPv6 Network Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for enabling IPv4 applications to communicate with each other through an IPv6 network require dedicated devices, leading to increased processing load and the risk of Single Point of Failure, as they lack efficient mechanisms for address translation and intercommunication between IPv4 and IPv6 nodes.
Innovation Solution
A method and device that modify the internal structure of host devices with IPv4 applications to convert IPv4 packet headers into IPv6 headers, allowing IPv4 applications to communicate through IPv6 networks without the need for external translation devices, thereby reducing network processing load and enhancing communication flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a border conversion gateway device is deployed to convert data packets between IPv4 and IPv6 networks, then communication between IPv4 applications over IPv6 network is enabled, but the processing load of the network system becomes very heavy and Single Point of Failure risk increases
Solution Approach 1:
The patent extracts the address translation function from the border gateway device and relocates it to the host device itself. The host device converts IPv4 packet headers to IPv6 headers locally, eliminating the need for external gateway translation and reducing the gateway's processing load to only routing functions.
Solution Approach 2:
The host device performs self-service by implementing its own IPv4-IPv6 packet header translation capability. This allows the host to independently convert packets without relying on external translation services, thereby reducing the processing burden on network gateways and improving system reliability.
2Adaptability or versatility
If an SIIT translator is used to translate data streams, then IPv6 applications can communicate with IPv4 nodes, but the processing load becomes very heavy and system reliability decreases due to Single Point of Failure
Solution Approach 1:
The translation functionality is extracted from the network translator and embedded directly into the host device's network stack. This distributes the translation function across multiple hosts rather than concentrating it in a single network translator, eliminating the single point of failure and improving system reliability.
Solution Approach 2:
The host device is designed with multi-functionality, capable of both sending and receiving translated packets. It can translate outgoing IPv4 packets to IPv6 and translate incoming IPv6 packets to IPv4, making the host itself a universal translation node rather than relying on dedicated translator infrastructure.
3Productivity
If packet header conversion is implemented at the host device, then processing load is reduced and communication flexibility is improved, but the host device structure must be modified
Solution Approach 1:
The patent segments the packet processing function into distinct components: an IPv4 protocol module, an IPv6 protocol module, and a conversion module. This segmentation allows the conversion logic to be isolated and managed separately, reducing the complexity impact on the overall host device structure while enabling efficient packet header translation.

AI summary
Provided are a method and a device of a host with IPv4 application for performing communication. The method of the host with IPv4 application for performing data communication includes the following steps: the IPv4 application generates an IPv4 packet sent to a communication end; when confirming the type of the network the host is located in is an IPv6 network, the host transforms the IPv4 packet head of the IPv4 packet to an IPv6 packet header, and sends it to the communication end via the IPv6 network. With this invention, it can be accomplished that according to the type of the network the host is located in, the host with IPv4 application communicates with a communication end; the processing load of the system is lightened; the probability that invalidation occurs at a single node is reduced; the smooth migration and transition from original IPv4 application to IPv6 system are facilitated.
