Automated VRF Alert Analysis for VPN Fault Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual Private Network (VPN) failures due to Virtual Routing and Forwarding (VRF) routing issues can cause service disruptions, and existing troubleshooting methods often fail to quickly identify the root cause, leading to prolonged downtime and customer service losses.
Innovation Solution
A system comprising an expert system and Common Test Platform (CTP) and Global Fault Platform (GFP) that automatically analyzes VRF alerts, filters out Layer one and two facility problems, correlates issues to Layer three, and notifies technicians or customers about configuration errors or exceeded maximum route limits, using heuristic rules and database information to expedite fault detection and resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If automated analysis of VRF alerts is implemented, then troubleshooting time is reduced, but system complexity increases
Solution Approach 1:
The patent introduces an automated analysis system that acts as an intermediary between VRF alerts and technicians. This system includes components for automatically analyzing VRF alerts, filtering out Layer one and two facility problems, correlating issues to Layer three, and notifying technicians or customers about configuration errors or exceeded maximum route limits using heuristic rules and database information.
2Device complexity
If manual troubleshooting methods are used, then system complexity remains low, but service downtime increases
Solution Approach 1:
The patent implements preliminary action by automatically analyzing VRF alerts as soon as they occur, rather than waiting for manual intervention. The system proactively filters problems, correlates issues to the appropriate layer, and notifies stakeholders before service disruption escalates, thereby reducing overall service downtime.
3Reliability
If automated fault detection is implemented, then service quality improves, but implementation cost increases
Solution Approach 1:
The patent segments the troubleshooting process into distinct automated functions: alert analysis, filtering Layer one and two problems, correlating to Layer three issues, and notification. This segmentation allows each function to be implemented and managed independently, reducing overall implementation complexity while maintaining high service quality.
Data Source
AI summary
Certain exemplary embodiments can provide a method that can comprise automatically rendering information indicative of a cause of a failure in a Virtual Private Network (VPN) that comprises one or more routers that utilize Virtual Routing and Forwarding (VRF) tables to route traffic via the VPN. The cause of the failure can be automatically determined.
