Directed Graph Update Path for Cloud Component Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Updating system components individually in cloud computing environments can lead to system bugs and interface mismatches due to mixed versions, and existing update processes are prone to errors and incompatibilities, especially when multiple systems fall out of synchronization.
Innovation Solution
A data structure that links all available updates with component identifiers and provides a map for optimizing the update path, using a directed graph to ensure interoperability and compatibility, and allowing a downgrade path in case of errors, along with a remote update service that utilizes a network ethernet card for secure update execution through DMA and NMI.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If system components are updated individually, then update flexibility and adaptability are improved, but system reliability deteriorates due to mixed versions and interface mismatches
Solution Approach 1:
The patent segments the update process into individual component updates while maintaining version coherence through a data structure that tracks component versions and their interdependencies. This allows flexible individual updates while preventing version conflicts through structured management of update sequences and compatibility checks.
Solution Approach 2:
The patent introduces a data structure as an intermediary that mediates between individual component updates and system-wide consistency. This data structure stores version information, dependency relationships, and compatibility rules, acting as a coordinator that ensures reliable integration of individually updated components.
2Productivity
If updates are propagated in batch mode to multiple systems, then update efficiency is improved, but reliability deteriorates due to synchronization issues and interface mismatches
Solution Approach 1:
The patent performs preliminary actions by pre-calculating and storing update paths in a data structure before actual updates are propagated. This includes determining compatibility relationships, version dependencies, and optimal update sequences in advance, allowing efficient batch updates while maintaining synchronization reliability through pre-validated update paths.
Solution Approach 2:
The patent introduces dynamic adaptability in batch updates by allowing the update propagation process to adjust based on system state feedback. The data structure enables dynamic selection of update paths and timing, allowing systems to maintain synchronization while accommodating varying update readiness states across multiple systems.
3Adaptability or versatility
If individual component updates are allowed, then system adaptability is improved, but device complexity increases due to version tracking and compatibility management
Solution Approach 1:
The patent creates a universal data structure that handles multiple functions: tracking component versions, managing dependency relationships, determining compatibility, and orchestrating update sequences. This multi-functional approach consolidates version management complexity into a single structured system that supports individual component updates while maintaining overall system coherence.
4Productivity
If batch updates are propagated to multiple systems, then productivity is improved, but device complexity increases due to synchronization coordination
Solution Approach 1:
The patent performs preliminary coordination by pre-determining update paths and compatibility relationships in the data structure before batch propagation. This advance preparation reduces the coordination complexity during actual update execution, allowing fast batch updates while maintaining synchronization through pre-planned update sequences stored in the structured data.

AI summary
An update process for updating components of one or more host devices includes selecting an update path for updating a system component of the one or more host devices and generating an update manifest including a plurality of update payloads for the system component that are included in the update path. The update path may be selected and/or derived based on a multi-stage combination of a hash of an update payload corresponding to a current version of the system component and respective hashes of the one or more update payloads using a reversible function to maintain backward and forward trackability and compatibility for the updates. A plurality of possible update paths may be represented in a directed graph that is managed by a control system. The update payloads may be uploaded to the host devices to cause the host devices to update the system component based on the update manifest.
