Some of these AVP values are used by the Diameter protocol itself, whileothers deliver data associated with particular applications that employ Diameter. AVPs may be added arbitrarily to Diameter messages, so long as the required AVPs are included and AVPs that are explicitly excluded are not included. AVPs are used by the base Diameter protocol to support the following required features: - Transporting of user authentication information, for the purposes of enabling the Diameter server to authenticate the user. - Transporting of service specific authorization information, between client and servers, allowing the peers to decide whether a users access request should be granted. - Exchanging resource usage information, which MAY be used for accounting purposes, capacity planning, etc. - Relaying, proxying and redirecting of Diameter messages through a server hierarchy. The Diameter base protocol provides the minimum requirements needed for a AAA protocol, as required by [AAAREQ]. The base protocol may be used by itself for accounting purposes only, or it may be used with a Diameter application, such as Mobile IPv4 [DIAMMIP], or network access [NASREQ]. It is also possible for the bas
