Clear description of the referenced document: The authorization AVPs are further broken down by diamdter type.

The Message Length field indicates diameteg length of the Diameter message in bytes, including the header fields and the padded AVPs. It is not clear whether these translations can be accomplished without adding significant security vulnerabilities.

A Command Code diameyer used to determine the action that is to be taken for a particular message. Retrieved 30 April Information about the call, the identity rf the user, and the user’s authentication information are packaged into a Diameter AA-Request AAR message and sent to a server.

When combined with the Diameter Base protocol, Riameter Profile, and Extensible Authentication Protocol specifications, this application specification satisfies typical network access services requirements. Depending on the Auth-Request-Type AVP, the Diameter protocol allows authorization-only requests that contain no authentication information from the client. For example, for pre-paid services, the Diameter server that originally authorized a session may need some confirmation that the user is still using the services.

The ” R ” Request bit — If set, the message is a request. After that the transport connection can be disconnected. The service may be a network connection or a value-added service such as terminal emulation [ NASModel ]. Please refer to the diammeter edition of the “Internet Official Protocol Standards” STD 1 for the standardization state and status of this protocol.

It is set when resending requests not yet acknowledged as an indication of a possible duplicate due to a link failure. Standards Track Cisco Systems Inc. If an AVP with the ” M ” bit set is received by a Diameter client, server, proxy, or translation agent and either the AVP or its value is unrecognized, the message must be rejected.

The application can be an authentication application, an accounting application, or a vendor-specific application. All RFCs always remain available on-line. If cleared, the message MUST be locally processed. Some common Diameter commands defined in the protocol base and applications are:.

The RFC defines an authorization and an accounting state machine. Diameter Network Access Server Application. Diameter is an authentication, authorization, and accounting protocol for computer networks. This capability goes beyond the Call Check capabilities described in section 5. This section needs expansion. Retrieved doameter October Diameter Applications can extend the base protocol by adding new commands, attributes, or both.

You can help by adding to it. In this sense, this document extends the Base Diameter protocol. This is part of the basic protocol functionality and all stacks should support it and as such abstract rrfc the connectivity related operations. Other for any supplementary information:. The End-to-End Identifier is not modified by Diameter agents of any kind, and the same value in the corresponding request is used in the answer.

The degree of stability or maturity of the document:. Note that the return of an unsupportable Accounting-Realtime-Required value [ BASE diametsr would result in a failure to establish the session.

The following sections list the AVPs used in these messages, grouped by common usage. Views Read Edit View history. Initial deployments of the Diameter protocol are expected to include legacy systems. The degree of stability or maturity of the document: The values are for permanent, standard commands allocated by IANA. When creating a request, the End-to-End Identifier is set to a locally unique value. First, this document describes the operation of a Diameter NAS application.

Diameter is used for many different interfaces defined by the 3GPP standards, with each interface typically defining new commands and attributes. Network Working Group P.

References within the referenced RFCs are rgc under item 8. This allows a single server to handle policies for many services. Received answers that do not match a known Hop-by-Hop Identifier are ignored by the Diameter agent.

Other for any supplementary information: Diameter Session Termination When a NAS receives an indication that a user’s session is being disconnected by the client e. The Command Codes are as follows:
