'''Diameter''' is an [[AAA (Computer security)|authentication, authorization, and accounting (AAA)]] protocol for computer networks. It evolved from the earlier [[RADIUS]] protocol. It belongs to the [[application layer]] protocols in the [[Internet protocol suite]].

''Diameter Applications'' extend the base protocol by adding new commands and/or attributes, such as those for use with the [[Extensible Authentication Protocol]] (EAP).
