Boot Time Delay Prediction for Computing Device Upgrades
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The boot time of computing devices is typically increased after an application upgrade, and users are often unaware of this delay, leading to unexpected restart times.
Innovation Solution
A method and system for determining boot time delays by receiving information about application upgrades, performing device emulation to generate an application upgrade strategy with predicted boot times, comparing these with actual boot times, and notifying users of the delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If application upgrades are performed on computing devices, then security vulnerabilities are protected against, but boot time is increased
Solution Approach 1:
The system performs device emulation in advance to predict boot time delays before actual upgrades are applied to production devices. This preliminary action allows the system to identify potential boot time increases and plan upgrade strategies accordingly, preventing unexpected delays during critical operations.
Solution Approach 2:
The system notifies users beforehand about predicted boot time delays caused by upcoming upgrades. This advance warning allows users to schedule restarts during maintenance windows or plan their work around the expected delays, cushioning the impact of increased boot times on productivity.
2Reliability
If application upgrades are performed, then security vulnerabilities are protected against, but users are unaware of restart times
Solution Approach 1:
The system provides feedback to users about predicted boot time delays through notifications and reports. The device emulation system generates predicted boot times that are communicated back to users, enabling them to make informed decisions about when to perform upgrades and restarts.
Solution Approach 2:
The system performs device emulation in advance to predict boot time delays before actual upgrades are applied to production devices. This preliminary action allows the system to identify potential boot time increases and plan upgrade strategies accordingly, preventing unexpected delays during critical operations.
3Measurement precision
If device emulation is performed to predict boot times, then accurate predictions are achieved, but system complexity increases
Solution Approach 1:
The system creates a virtual copy (emulation) of the target device to perform boot time measurements. This copy replicates the hardware and software configuration of the actual device, allowing accurate prediction of boot time delays without affecting the production system. The emulation environment serves as a safe test bed for evaluating upgrade impacts.
Solution Approach 2:
The device emulation system acts as an intermediary between the upgrade planning process and the actual production devices. Rather than directly measuring boot times on production systems, the emulation environment serves as a mediator that provides predicted values, isolating the measurement process from critical operational systems.

AI summary
A method for upgrading a client device includes: performing an emulation to generate an application upgrade strategy to apply a plurality of application upgrades on a client device, in which the application upgrade strategy is associated with a plurality of emulated boot times; comparing the plurality of emulated boot times with an actual boot time obtained from the client device; determining, based on the comparison, a boot time delay; generating a final application upgrade strategy, in which the final application upgrade strategy specifies the boot time delay; and initiating upgrading of the client device using the final application upgrade strategy in response to feedback from a user.
