Network Device Data Erasure via Carrier Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network devices such as switches, routers, and access points often have user-configured settings that need to be erased or reset, particularly when returned to manufacturers or third parties, but existing methods lack efficient and secure solutions for removing these configurations.
Innovation Solution
A system and method involving a computer device and server communication to retrieve configuration files, perform factory resets, clear user-addressable storage, and backup firmware, while ensuring secure passcode removal and serial number validation to prevent unauthorized access and ensure proper resetting and erasing of network devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data erasure methods are used on network devices, then security concerns arise and unauthorized access may occur, but automated solutions increase system complexity
Solution Approach 1:
The network device performs self-erasure by automatically executing the data erasure process when it detects it has been placed in a carrier, eliminating the need for manual intervention and ensuring consistent secure erasure without requiring complex external systems
Solution Approach 2:
The system separates the erasure trigger mechanism (carrier detection) from the erasure execution (device-internal process), allowing the carrier to simply hold the device while the device itself manages the complex erasure operations, reducing overall system complexity
2Productivity
If multiple network devices are processed concurrently, then productivity increases, but ensuring proper erasure of each device becomes more difficult
Solution Approach 1:
Each network device contains its own erasure capability and execution logic, creating independent copies of the erasure function in each device. This allows multiple devices to be processed simultaneously without requiring centralized tracking, as each device autonomously manages its own erasure process
Solution Approach 2:
Each device independently detects when it is in a carrier and autonomously executes its erasure process without requiring external coordination or tracking systems, enabling concurrent processing of multiple devices while simplifying the overall system architecture

AI summary
A method includes determining, by a computer device, device information for a network device communicatively coupled to the computer device. The method includes retrieving, from a server device, a configuration file corresponding to the device information as determined. The method includes resetting the network device using the configuration file as retrieved. The method includes clearing user-addressable storage locations of the network device. The method includes outputting an indication of whether resetting the network device was successful and whether clearing the user-addressable storage locations of the network device was successful.
