The service may be a network connection or a value-added service such as terminal emulation [ NASModel ].

This is achieved by including the RADIUS attribute space to eliminate the need to perform many attribute diameher. Diameter Applications can extend the base protocol by adding new commands, attributes, or both.

Clear description of the referenced document:. Please refer to the current edition of the “Internet Official Protocol Standards” STD 1 for the standardization state and status of this protocol. References within the referenced RFCs are listed under item 8.

If cleared, the message MUST be locally processed.

Any explicit references within that referenced document should also be listed:. Committed to connecting the world. Obsolete RFCs are indicated with strikethrough text. Information about the call, the identity of the user, and the user’s authentication information are packaged into a Diameyer AA-Request AAR message and sent to a server.

Other for any supplementary information: Some common Diameter commands defined in the protocol base and applications are:. The following sections list the AVPs used in these messages, grouped by common usage. Retrieved from ” https: Diameter Session Termination When a NAS receives an indication that a user’s session is being disconnected by the client e.

When combined with the Diameter Base protocol, Transport Profile, and Extensible Authentication Protocol specifications, this application specification satisfies typical network access services requirements. This will ensure that any resources maintained on the servers are freed appropriately. Archived from the original on 4 July The authorization AVPs are further broken down 40005 service type.

The values are for permanent, standard commands allocated by IANA. From Wikipedia, the free encyclopedia. Diameter Relay and redirect agents must not reject messages with unrecognized AVPs.

The Diameter protocol requires that relaying and proxying agents maintain transaction state, which is used for failover purposes. This capability goes beyond the Call Check capabilities described in section 5.

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 server will respond with an AAA message to specify the new service parameters.

Diameter (protocol)

Comments on RFCs and corresponding changes are accommodated through the existing standardization process. Internet Standards Application layer protocols Computer access control protocols Authentication protocols. First, this document describes the operation of a Diameter NAS application.

A design prior to PPP. As a result, service cannot be started as a result of a response to an authorization-only request without introducing a significant security vulnerability. It is set when resending requests not yet acknowledged as an indication of a possible duplicate due to a link failure. Messages with the “E” bit set are commonly referred to as error messages. Other for any supplementary information:. If authorization was requested, a successful response will include the authorization AVPs appropriate for the service being provided, as defined in section 6.

Then it defines the Diameter message Command-Codes.

RFC – Diameter Network Access Server Application

The name is a play on words, derived from the RADIUS protocol, which is the predecessor a diameter is twice the radius. Diameter is an authentication, authorization, and accounting protocol for computer networks. A Command Code is used to determine the action that is to be taken for a particular message. Views Read Edit View history. In case of redirecting agents, the Hop-by-Hop Identifier is maintained in the header as the Diameter agent responds with an answer message.

Retrieved 12 October This field indicates the version of the Diameter Base Protocol. This is part of the basic protocol functionality and all stacks should support it and as such abstract from the connectivity related operations.
