Network Monitoring & Maintenance: A Case Study on Enhancing Telco Network Performance

Executive Summary

In this edition, we explore a significant case study on overcoming networking monitoring and maintenance challenges. We provide an in-depth look at the problem, the solution implemented, and the business value derived. Our focus is on enhancing network performance, security, and efficiency, particularly through monitoring Elastic Network Interfaces (ENIs) and the critical N6 component.

Problem Statement

In the rapidly evolving digital landscape of 2024, maintaining network performance, security, and reliability is more crucial than ever. Traditional network monitoring and maintenance methods are proving inadequate due to the complexity of modern networks. This often leads to:

• Security Risks: Increased vulnerability to undetected threats.
• Performance Challenges: Reduced user experience and SLA compliance.
• Operational Inefficiencies: Higher costs and extended downtime.
• Compliance Concerns: Risk of legal penalties and reputational damage.
• Resource Optimization Issues: Ineffective resource allocation.
• Limited Business Insights: Hindered data-driven decision-making.

Solution Proposed

Approach:

To tackle these challenges, we implemented a multi-faceted solution to effectively monitor and manage N6 logs:

1. Comprehensive Log Collection: Real-time or scheduled collection of N6 logs from all network devices.
2. Centralized Log Storage: Secure and scalable cloud-based storage solutions.
3. Log Parsing and Normalization: Standardized log formats for ease of analysis.
4. Real-time Log Monitoring: Advanced analytics and machine learning for anomaly detection.
5. Automated Remediation: Context-aware response using machine learning.
6. Visualization and Reporting: Interactive dashboards and customizable reports for stakeholders.

Architecture

Brief Description of Figure above:??

• The entire infrastructure operates on AWS cloud services.?

• The diagram illustrates the flow of data starting from mobile devices to the Radio Access Network (RAN) and beyond.?

• This architecture serves as the foundation upon which the solution has been built.?

• Key tools and technologies integrated into the architecture include AWS EKS, Local Gateway, and Firewall.?

?Brief Description of the figure above:??

• The diagram illustrates the solution built atop the N6 flow (as depicted in Figure 1).?

• Initially, log data from N6 is ingested and stored in AWS S3.?

• Subsequently, the data undergoes analysis, followed by model building and training using Amazon SageMaker.?

• Finally, the solution provides model inference and showcases analysis through a Dashboard (AWS QuickSight).?

• Tools and Technologies – AWS S3, AWS Sagemaker, AWS Athena and AWS Quicksight.??

Outcome

Refined Network Traffic Analysis:

• Traffic Volume Monitoring: Identify anomalies in bytes and packets to detect potential issues.
• Source and Destination Inspection: Detect unusual patterns or connections.
• Protocol Scrutiny: Monitor for unauthorized protocol usage.
• Flow Direction Analysis: Ensure traffic follows expected paths.
• Timestamp Evaluation: Identify suspicious activities based on event duration.
• Geolocation Tracking: Spot anomalies in traffic origins.

Enhanced Network Maintenance:

• AI models analyze historical data to identify and address behavioral patterns, enhancing proactive maintenance and risk management.

Business Value

Informed Decision Making: Data-driven insights align network strategies with business goals, driving growth.

Fast Incident Response: Quick identification and mitigation of security incidents ensure business continuity.

Compliance and Audit Readiness: Adherence to regulatory standards fosters stakeholder trust and protects the organization’s reputation.
