Diameter: Diameter is an authentication, authorization, and accounting (AAA) protocol designed as an upgrade to RADIUS. While it offers advancements like better security, scalability, and flexibility, Diameter is predominantly employed in mobile IP-based networks rather than replacing RADIUS in all contexts. RADIUS remains widely used, particularly in traditional network environments.
