Client Overview

Dialog Axiata PLC, Sri Lanka’s leading mobile and telecommunications providers, delivers reliable enterprise connectivity solutions to organizations across the country — including banks, hotels, and major retail chains.

Service Domain

Enterprise Internet – AAA (Authentication, Authorization, and Accounting) System

Challenges

1. Outdated AAA System and Security Patch Limitations

Dialog’s existing AAA system struggled with security patch updates.
The system was incompatible with the latest Red Hat OS versions, creating security and maintenance risks.
This limited their ability to keep servers compliant with modern security standards.

2. Multiple AAA Instances for Different Authentication Types

Dialog was using multiple AAA instances to manage different types of authentication and accounting systems — leading to high maintenance costs, complex configurations, and increased operational overhead.

They needed a unified, flexible AAA solution that could support multiple Network Access Server (NAS) types under one architecture.

Solution: Monyfi AAA Implementation

Monyfi deployed a high-performance AAA solution built for scalability, multi-NAS compatibility, and enterprise-level reliability.

Key Features Implemented

• Support for multiple NAS types:
  1. Huawei BNG
  2. Huawei PGW
  3. Cisco LNS

• Supported Authentication & Accounting Types:
  • 4G LTE Authentication & Accounting
  • GPON (Fiber) Authentication & Accounting
  • Enterprise Internal Network Authentication & Accounting
    (for corporate networks like banks, hotels, and retail chains such as Singer and Abans)

• Full compatibility with the latest Red Hat OS versions — ensuring regular security patching without service disruption.

• Centralized AAA instance capable of handling all authentication methods within a unified framework.

Architecture Overview

Primary Site

• 3 Application Nodes + 1 Load Balancer Node
• 2 Database Servers
• 1 Monitoring Node + 1 Logging Node

Disaster Recovery (DR) Site

• 3 Application Nodes + 1 Load Balancer Node
• 1 Database Server

Real-time data synchronization between the primary and DR sites ensures continuous service availability and disaster resilience.
