Edge Device Bootstrapping Package for Automated Disaster Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual configuration of replacement edge devices is cumbersome, prone to errors, and time-consuming, especially when the new device has different hardware or software than the device being replaced, and often requires transmitting large configuration data across limited or disconnected networks.
Innovation Solution
The system generates a bootstrapping package based on the current device configuration of the first edge device, segmenting the device state and workload configuration into namespaces, which is then automatically installed on a second edge device, allowing for seamless configuration without manual intervention and accommodating differences in hardware or software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration is used for replacement edge devices, then configuration can be performed with basic tools, but the process is cumbersome, error-prone, and time-consuming
Solution Approach 1:
The patent creates a virtual copy of the failed edge device's configuration state and workload information, packaging it into a bootstrapping package that can be automatically deployed to the replacement device. This copying approach eliminates manual configuration by transferring the complete operational state as a template.
Solution Approach 2:
The system performs preliminary actions by capturing the device state and workload configuration before the device fails, and pre-processes this information into a ready-to-install bootstrapping package. This preliminary preparation ensures that when replacement is needed, the configuration is already prepared and can be applied immediately without manual intervention.
2Reliability
If manual configuration is used for replacement edge devices, then simplicity is maintained, but errors are prone and reliability is reduced
Solution Approach 1:
The replacement edge device performs self-configuration by automatically receiving and installing the bootstrapping package containing the failed device's configuration state and workload information. The system enables the device to configure itself without human intervention, eliminating manual errors while managing complexity through automation.
Solution Approach 2:
By creating an accurate virtual copy of the device state, workload configurations, and other critical information, the system ensures reliable replication of the failed device's operational state. This copying mechanism guarantees configuration accuracy while the automated process manages the complexity of transferring comprehensive device information.
3Reliability
If complete configuration data is transmitted for replacement devices, then configuration accuracy is maintained, but network bandwidth consumption increases and disconnected networks cannot be used
Solution Approach 1:
The patent segments the complete device configuration into distinct components: device state information, workload configuration data, and other metadata. This segmentation allows the system to package and transmit only the essential configuration elements needed for replacement, reducing network bandwidth requirements while maintaining configuration accuracy.
Solution Approach 2:
The system creates an optimized virtual copy of the configuration data, capturing only the critical state information and workload configurations necessary for functional replication. This selective copying approach ensures configuration accuracy while minimizing the data volume transmitted over the network, enabling operation even in disconnected or low-bandwidth environments.
4Productivity
If automated configuration is implemented, then configuration time is reduced and productivity increases, but system complexity increases
Solution Approach 1:
The automated configuration system uses virtual copying to capture the complete operational state of the failed device and replicate it on the replacement device. This copying mechanism enables rapid configuration deployment, significantly improving productivity while the systematic approach to packaging and installing configuration data manages the added system complexity.
Solution Approach 2:
The system performs preliminary capture and processing of device state and workload information before the actual replacement occurs. By pre-packaging the configuration data into a bootstrapping package, the system prepares everything needed for rapid deployment, improving configuration speed while the preliminary processing steps manage the complexity of handling comprehensive device information.
