• RADIUS (AAA) Integration & Management
• 🚀 Project Description:
• RADIUS (Remote Authentication Dial-in User Service) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users connecting to and using a network service. It integrates with various broadband network elements like NAS systems and Bandwidth Managers. RADIUS is a client-server protocol that runs in the application layer using UDP as the transport protocol.
• 🔧 Key Responsibilities:
• 🔹 Developed and integrated Multi-Level Fair Usage Policy Plan and Add-on plans into the Radius Server (AAA), resulting in a 25% increase in subscription upgrades.
• 🔹 Implemented MAC authentication functionalities as per client requirements, enabling and disabling access as needed to meet specific security requirements.
• 🔹 Worked with the RADIUS protocol, supporting centralized Authentication, Authorization, and Accounting (AAA) management for users connecting to network services.
• 🔹 Integrated Radius with broadband network elements like NAS systems and Bandwidth Manager to extend its functionality across the network.
• 🔹 Managed the RADIUS server, ensuring proper configuration and optimal performance in the centralized authentication system.
• 🔹 Utilized the IETF standard RFC 2865 and RFC 2866 for RADIUS, running in the application layer and using UDP as the transport protocol.
