Dual-Stack Protocol Switching for IPv6 Error Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition from IPv4 to IPv6 communication protocols is complicated by their non-interoperability, leading to time-consuming and expensive solutions when errors occur, requiring either fixing the protocol stacks or modifying applications to use IPv4 protocols.
Innovation Solution
An information handling system with dual-stack implementation, featuring both IPv6 and IPv4 protocol stacks, allows for transparent error handling by sending communication payloads through IPv4 stacks in case of IPv6 errors, enabling continuous operation without modifying IPv6 applications or fixing protocol stacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IPv6 protocol stack is used for communication, then modern addressing capability is achieved, but communication reliability deteriorates when protocol errors occur
Solution Approach 1:
The patent introduces an intermediary mechanism that monitors protocol communication and automatically switches between IPv6 and IPv4 protocols when errors are detected. This mediator layer allows the system to maintain communication reliability by falling back to a compatible protocol without requiring application-level changes or manual intervention.
Solution Approach 2:
The system dynamically changes the protocol parameter (switching between IPv6 and IPv4) based on communication status. When IPv6 communication fails, the system automatically transitions to using IPv4, thereby maintaining adaptability while ensuring continuous operational reliability.
2Reliability
If error fixing or application modification is performed, then communication reliability is improved, but time consumption and cost increase
Solution Approach 1:
The system performs preliminary configuration by installing both IPv6 and IPv4 protocol stacks in advance, along with the monitoring mechanism. When communication errors occur, the pre-configured fallback mechanism enables immediate switching without requiring time-consuming error analysis, debugging, or application modification.
Solution Approach 2:
The communication system implements self-service error handling through automatic protocol switching. The monitoring mechanism detects communication failures and autonomously switches between protocols without human intervention, eliminating the need for manual error fixing or application modification and significantly reducing time loss.
3Adaptability or versatility
If dual-stack implementation is used, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments the communication system into distinct protocol stack layers (IPv6 stack, IPv4 stack, and monitoring/switching layer). This segmentation allows each component to operate independently with well-defined interfaces, managing complexity through modular architecture while maintaining dual-protocol adaptability.

AI summary
A communication transmission system includes a server client couple by a network. The client includes a first protocol client application that uses a first communication protocol, a client first protocol stack that communicates using the first communication protocol, and a client second protocol stack that communicates using a second communication protocol different from the first communication protocol. The client sends a first communication payload from the first protocol client application to the server using the client first protocol stack. If an error is received sending of the first communication payload, a copy of the first communication payload is sent to the server using the client second protocol stack. A second communication payload is then received from the server using the client second protocol stack in response to sending the first communication payload, and the second communication payload is provided to the first protocol application using the client first protocol stack.
