• Server Redundancy ->arbitrary server failure

• Site Redundancy -> central power outage, natural disasters

• Data Redundancy

Introduction to One-AAA – What is AAA ?

Authentication : check that the user has access to a network (via credentials)

Authorization: grant specific type of services to a user (based on authentication)

Accounting : track consumption of network resources by users

• RADIUS is current standard protocol for AAA

• Diameter: upcoming standard protocol for AAA

– Better transport– Better proxying– Better session control– Better security
