Digital Twin for Lossless Network Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital systems that rely on a central server are vulnerable to connection losses due to malfunctions or external factors like natural disasters, leading to inaccurate updates and data provisioning issues.
Innovation Solution
A platform is developed to create a digital twin of the digital system, which includes a processor, non-transitory memory, and computer-executable instructions to store core and secondary hardware and software components, detect performance metrics, and simulate the system's performance. This platform syncs with the digital system during disconnection from the central server and updates the central server when reconnection occurs, allowing for lossless restoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital systems rely on a central server for updates and data provisioning, then centralized control and coordination are improved, but vulnerability to connection losses and system reliability deteriorate
Solution Approach 1:
The patent creates a digital twin as a virtual copy of the physical digital system. This digital twin replicates the system's components, data, and operations, allowing it to function independently when disconnected from the central server. The digital twin maintains local copies of all system data and can execute operations autonomously, ensuring continuity of service during network disruptions while preserving the benefits of centralized architecture when connected.
Solution Approach 2:
The system performs preliminary actions by continuously synchronizing the digital twin with the central server before disconnections occur. All necessary data, updates, and system states are pre-loaded into the digital twin while connected, enabling the system to operate independently when the connection is lost. This preliminary preparation eliminates the need for complex real-time synchronization protocols during disconnection events.
2Productivity
If the system operates independently during disconnection, then operational continuity is improved, but data consistency and synchronization with the central server worsen
Solution Approach 1:
The patent implements a feedback mechanism where the digital twin continuously monitors its own operational state and compares it with the last known state from the central server. Upon reconnection, the system automatically detects and resolves any data inconsistencies through bidirectional synchronization. The feedback loop ensures that both the central server and digital twin converge to a consistent state, maintaining data integrity while allowing independent operation during disconnections.
Solution Approach 2:
The synchronization mechanism dynamically adapts its behavior based on connection status. During disconnection, the digital twin operates autonomously with full functionality. Upon reconnection, the system dynamically switches to synchronization mode, where changes from both the central server and digital twin are reconciled. This dynamic approach allows operational continuity during disconnection while ensuring data consistency is restored upon reconnection.
3Ease of repair
If a digital twin is created to enable lossless restoration, then system restoration capability is improved, but computational resources and energy consumption worsen
Solution Approach 1:
The digital twin is created as a virtual copy that replicates only the essential system components, data structures, and operational logic needed for restoration. Rather than duplicating entire system images or maintaining multiple redundant copies, the digital twin uses optimized data representations that minimize storage and computational requirements while preserving full restoration capability.
Solution Approach 2:
The system dynamically adjusts the level of detail and fidelity of the digital twin based on operational needs. During normal operation, the digital twin maintains essential system state information. When restoration is required, the system can enhance the digital twin's detail level by loading additional data from backups or the central server. This parameter adjustment allows the system to balance restoration capability with energy and computational constraints.
