Network Alerting System (NAS)

The Network Alert System (NAS) is a critical subsystem of the network management framework. It provides comprehensive visibility and control over network alerts — from end devices to core switches and routers. NAS enables administrators to monitor, analyze, and respond to issues efficiently, thereby enhancing the overall performance and reliability of the network.

Features and Functionalities

Network Alerts Dashboard

The NAS features a powerful dashboard that visualizes ongoing network alerts and highlights the current health status of the infrastructure.

Key elements include:

  • Devices on Alert: Displays the number of devices currently experiencing issues.

  • Alerts by Severity Level: Bar and pie charts represent the number of alerts categorized using the standard syslog severity scale (0 = Emergency, 4 = Warning).

These visualizations enable administrators to quickly understand the scale and seriousness of issues across the network.

List of System Alerts

The NAS provides a detailed, filterable table of all generated system alerts for granular analysis and response.

AI Recommendation and Insight

One of the standout features of NAS is its AI-driven recommendation engine. This system helps administrators resolve issues efficiently by providing:

  • Root Cause Analysis: Identifies the underlying problem of the alert.

  • Resolution Guidance: Provides step-by-step instructions tailored to the alert.

  • Device-Specific Commands: Offers relevant commands based on the device vendor/OS, supporting multi-vendor environments such as:

    • Cisco IOS (Cisco)

    • Junos OS (Juniper)

    • Huawei VRP (Huawei)

This level of intelligence helps significantly reduce troubleshooting time and minimizes manual errors.

Integration with Other Subsystems

NAS is seamlessly integrated into the broader system. It interacts with other modules (like QTI) to provide a unified view of the network health and event correlation.

Future Enhancements

The NAS subsystem is built with extensibility in mind. Future improvements will include:

Predictive Alerting

  • Proactive Detection: Analyze device configurations and security services to forecast potential issues.

  • Predictive Alerts: Warnings are issued before a failure occurs if risky configurations or disabled services are detected.

Automated Remediation

  • AI-Driven Fixes: Automatically execute commands or scripts based on the AI recommendation engine to resolve known issues without human intervention.

Real-Time Notifications

  • Instant Visibility: New alerts will trigger real-time notifications in the NOS sidebar and within the NTM module, ensuring administrators are informed immediately.

Visibility and Transparency

  • Ticketing System: A built-in coordination system will allow administrators to:

    • Track which alerts are actively being handled.

    • Avoid duplicated efforts.

    • Improve collaboration between network teams.
