Peer-Assisted Network Update Self-Healing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network administrators often delay or forego software updates for networking devices due to high failure rates, which can lead to security vulnerabilities and inefficiencies, especially in large enterprise networks.
Innovation Solution
Implementing a peer-assisted image update system that allows devices to automatically install updates in a distributed manner, with peer monitoring and self-healing capabilities to detect and correct installation failures, ensuring seamless updates even if the device becomes unreachable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software updates are installed frequently to fix bugs and security concerns, then device security and functionality are improved, but update failure rate increases and administrative overhead increases
Solution Approach 1:
The patent implements self-healing capabilities where the updating device automatically detects update failures and recovers by obtaining backup update data from neighboring devices without requiring manual administrative intervention. This automates the update process, reducing both failure impact and administrative overhead while maintaining security through frequent updates
Solution Approach 2:
The patent introduces neighboring devices as intermediaries that store and share backup update data. When an update failure occurs, the affected device retrieves recovery data from neighbors rather than requiring centralized server intervention, simplifying update management while maintaining security
2Reliability
If software updates are delayed to avoid installation failures, then network stability is maintained, but security vulnerabilities accumulate and device functionality becomes outdated
Solution Approach 1:
The patent implements a preparatory mechanism where neighboring devices store backup update data before updates are needed. This cushioning of resources ensures that when security-critical updates are needed, devices can immediately recover from failures without delaying updates, thus eliminating security vulnerabilities while maintaining network stability
Solution Approach 2:
Devices automatically detect and recover from update failures using peer-assisted data retrieval, enabling rapid re-attempt of security updates without manual intervention or network-wide delays, thus maintaining both stability and security
3Reliability
If manual monitoring of update installations is performed to detect failures, then update reliability is improved, but administrative time and resources increase significantly
Solution Approach 1:
The patent implements automatic failure detection and self-healing mechanisms where devices monitor their own update installations and autonomously recover from failures by retrieving backup data from neighbors. This eliminates the need for manual administrative monitoring while maintaining high update reliability, significantly reducing administrative time investment
Solution Approach 2:
The system implements automated feedback loops where devices continuously monitor update status, detect failures, and trigger self-healing procedures. This automated feedback mechanism maintains update reliability without requiring human intervention, freeing administrative time for higher-value tasks
Data Source
AI summary
In one embodiment, a device in a network receives update recovery data from a neighbor of the device in the network. The device monitors the neighbor during installation of a software update by the neighbor. The device detects an installation failure of the software update by the neighbor. The device causes recovery of the neighbor using the update recovery data, in response to detecting the installation failure of the software update by the neighbor.
