Network Issue Identification via Managed Node Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IT administrators face challenges in identifying and resolving network issues, particularly in remote computing environments, due to intermittent problems and complex network configurations, which can lead to network congestion and performance degradation.
Innovation Solution
A method involving a management server that collects network performance data from managed nodes, including unmanaged links, to identify issues such as latency and packet drops, and generates notifications to address these problems dynamically by adjusting link routes and profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If network monitoring is performed manually, then device complexity is reduced, but network issue identification speed and accuracy deteriorate
Solution Approach 1:
The managed node automatically performs network diagnostics including trace route, ping, and packet loss testing without requiring manual intervention from IT administrators. The system self-monitors network performance and generates its own notifications, eliminating the need for complex manual monitoring processes while maintaining comprehensive network visibility.
Solution Approach 2:
The system continuously monitors network performance metrics and provides real-time feedback through automated notifications when thresholds are exceeded. This feedback mechanism enables dynamic response to network issues without requiring complex manual analysis, improving detection speed while keeping the monitoring system relatively simple.
2Measurement precision
If comprehensive network monitoring is implemented, then network issue detection accuracy is improved, but time loss increases
Solution Approach 1:
The system performs network diagnostics in advance by automatically executing trace route and packet loss tests before issues manifest as problems. This preliminary monitoring action enables early detection of network degradation trends, allowing proactive intervention rather than reactive response, thereby reducing overall time loss despite comprehensive monitoring.
Solution Approach 2:
The system conducts network performance measurements at periodic intervals rather than continuously, balancing monitoring comprehensiveness with time efficiency. The managed node performs diagnostics at scheduled intervals and immediately upon threshold violations, providing accurate measurements without the time penalty of continuous manual monitoring.
3Productivity
If manual troubleshooting is used, then device complexity is reduced, but productivity deteriorates
Solution Approach 1:
The managed node autonomously performs network troubleshooting by automatically executing diagnostic commands, analyzing results, and generating notifications without requiring IT administrator intervention. This self-service capability dramatically improves resolution speed while the automation logic remains relatively simple and maintainable.
Solution Approach 2:
The system introduces an automated intermediary layer between network issues and IT administrators. The managed node acts as a mediator that collects network data, analyzes performance metrics, and communicates status to administrators through notifications, enabling rapid automated response while keeping the administrator's role simple and focused on high-level management.
Data Source
AI summary
In some examples, a method includes receiving, at a management server, network performance information from a managed node. In some examples, the network performance information includes data corresponding to an unmanaged link between the managed node and an unmanaged target device. In some examples, the method includes identifying a network issue with the unmanaged link based on the data. In some examples, the method includes generating a notification indicating the network issue.
