Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern avionic architectures face challenges in storing large volumes of digital data due to the need for multiple redundant storage locations, which increases integration complexity and costs, while also requiring efficient management of access rights and data segregation.
Innovation Solution
A storage method utilizing a deterministic avionic network with predetermined routing, where digital files are sent with a time reference and integrity digest across multiple switches, allowing for efficient storage and retrieval without dedicated storage locations, leveraging the network's determinism and redundancy for secure and segregated data management.

1Quantity of substance
If dedicated storage locations are multiplied in various end systems to store large volumes of data, then data storage capacity and redundancy are improved, but device complexity and integration difficulty increase
Solution Approach 1:
The patent merges the storage function from individual end systems into the network switches themselves. Instead of each end system having dedicated storage locations, the switches in the avionic network are equipped with storage units that can store digital files. This consolidation reduces the number of separate storage components while maintaining storage capacity and redundancy through the network's inherent structure.
Solution Approach 2:
The network switches are given multiple functions: they not only route data frames but also perform storage operations. The switches can store digital files, manage access rights, and provide deterministic access to data, making them universal components that replace both routing and storage functions previously handled by separate dedicated storage locations in end systems.
2Reliability
If redundant storage locations are implemented to ensure data resilience, then data reliability is improved, but device complexity and costs increase
Solution Approach 1:
The patent combines redundancy functionality into the network switch storage units rather than implementing separate redundant storage locations in each end system. The switches can store multiple copies of digital files and manage redundancy through the network's deterministic routing capabilities, reducing overall system complexity while maintaining resilience.
Solution Approach 2:
The patent utilizes copying of digital files within the network switch storage units to achieve redundancy. Instead of physically replicating storage hardware in each end system, the system creates and maintains copies of data files within the distributed storage units of network switches, achieving redundancy through data replication rather than hardware duplication.
3Reliability
If access rights management is implemented for different types of data, then data security and segregation are improved, but ease of operation decreases
Solution Approach 1:
The network switches autonomously manage access rights to stored data without requiring complex centralized authorization systems. The switches themselves enforce security policies and control access based on the nature of the data and the requesting end system, simplifying the operational burden while maintaining strong security through distributed decision-making at the network level.

AI summary
The present invention relates to a storage method of digital files carried out by a determinist avionic network with predetermined routing. This method comprises a phase (PE) for writing digital files comprising the steps of determining by an end system sending a digital file to be stored, associating a time reference with the digital file to be stored, sending the digital file to be stored with the associated time reference to K separate switches using one or several data frames, generating, via at least some of the switches, a copy of the digital file to be stored and storing this copy in the storage unit of each of these switches with the associated time reference.
