Automated Fault Isolation System for Managed Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network monitoring systems face challenges in efficiently detecting and resolving faults due to overwhelming volumes of alarm reports, leading to prolonged downtime and increased costs, especially in large modern networks where manual processing is cumbersome and often requires human intervention.
Innovation Solution
An automated fault isolation and recovery system that transmits notification configurations to user interfaces, receives notification messages, and performs fault isolation and recovery based on workflow events, integrating with customer networks to streamline the process and reduce human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual processing of alarm reports is used, then human analysis and decision-making is possible, but fault resolution time increases and productivity decreases
Solution Approach 1:
The system enables self-service automation where the fault management system automatically executes fault isolation and recovery actions without requiring continuous human intervention. The automated workflow performs diagnostic actions, generates trouble tickets, and coordinates recovery efforts independently, transforming manual processing into autonomous operation while maintaining human oversight for complex decisions.
Solution Approach 2:
The system performs preliminary actions by pre-configuring fault isolation procedures, pre-identifying affected customers, and pre-preparing recovery workflows before faults occur. When faults happen, these pre-established procedures enable immediate automated response, reducing resolution time compared to manual assessment and planning.
2Adaptability or versatility
If comprehensive notification options are provided to customers, then customer communication control is improved, but system complexity increases
Solution Approach 1:
The notification system employs dynamic configuration where customers can customize notification preferences through a user-friendly interface. The system adapts notification delivery methods, timing, and content based on customer-specific requirements stored in configuration data, allowing flexible customization without exposing complex underlying system architecture.
Solution Approach 2:
The system introduces an intermediary notification management layer that sits between the fault detection system and customer communication channels. This intermediary handles the complexity of multiple notification methods (email, SMS, web portal), customer preference management, and message routing, shielding customers from system complexity while providing comprehensive communication options.
3Loss of time
If automated fault isolation is implemented, then fault resolution time is reduced, but initial system implementation cost increases
Solution Approach 1:
The automated fault isolation system is segmented into distinct functional modules: fault detection module, impact analysis module, customer notification module, and recovery coordination module. Each module handles specific aspects of fault management independently, making the complex system more manageable and easier to implement incrementally. The segmentation allows organizations to deploy core automation functionality first and add advanced features later.
Data Source
AI summary
An approach for supporting automated fault isolation and recovery is provided. A notification configuration option is transmitted to a browser interface utilized by a user associated with a customer network that is monitored by a service provider, wherein the user selects the notification configuration option to input notification information. The notification information is received, via the browser interface, from the customer. A notification message is received from a platform configured to create a workflow event in response to an alarm indicative of a fault within the customer network, wherein isolation and recovery of the fault is performed according to the workflow event, the notification message including information about the customer network during the fault isolation and recovery process. The notification message is transmitted in accordance with the stored notification information.
