The degree of stability or maturity of the document:. A request for authorization will include some AVPs defined in section 6. You can help by adding to it. Other for any supplementary information: The ” R ” Request bit — If set, the message is a request. When set the AVP Code belongs to the specific vendor code address space. Clear description of the referenced document: Retrieved from ” https: The values are for permanent, standard commands allocated by IANA. The Message Length field indicates the length of the Diameter message in bytes, including the header fields and the padded AVPs.
This allows a single server to handle policies for many services.
Other useful information describing the “Quality” of the document:. Additionally, application specific state machines 44005 be introduced either later or at a higher abstraction layer.
Justification for the specific reference: The ” E ” Error bit — If set, the message contains a protocol error, and the message will not conform to the CCF described for this command. After that the transport connection can be disconnected.
Diameter (protocol) – Wikipedia
Any explicit references within that referenced document should also be listed:. The Diameter protocol defines a policy protocol used by clients to perform policy, AAA, and resource control. In case of redirecting agents, the Hop-by-Hop Identifier is maintained in the header as the Diameter agent responds with an answer message. Diameter is used for many different interfaces defined by the 3GPP standards, with each interface typically defining new commands and attributes. Diameter Session Termination When a NAS diamrter an indication that a user’s session is being disconnected by the client e.
Messages with the “E” bit set are commonly referred to as error messages. Diameter Network Access Server Application.
The server will respond with an AAA message to specify the new service parameters. Application-ID is used to identify for which Diameter application the message is applicable. Obsolete RFCs are indicated with strikethrough text. Retrieved 12 October Please refer to the current edition of the “Internet Official Protocol Standards” STD 1 for the standardization state and status of this protocol.

Current information, if any, about IPR issues:. The RFC defines an authorization and an accounting state machine. The packet consists of a Diameter header and a variable number of Attribute-Value Pairs, or AVPs, for encapsulating information relevant to the Diameter message.
VPN Virtual Private Network – In this document, this term is used to describe access services that use tunneling methods. This capability goes beyond the Call Check capabilities described in section 5.
The degree of stability or maturity of the document: Diameter is an authentication, authorization, and accounting protocol for computer networks. Depending on the Auth-Request-Type AVP, the Diameter protocol allows authorization-only requests that contain diajeter authentication information from the client. In this sense, this document extends the Base Diameter protocol. Call and Session Information. Relationship with other existing or emerging documents:.
Distribution of this memo is unlimited. As ofthe only value supported is 1. If cleared, the message MUST be locally processed.
When combined with the Diameter Base protocol, Transport Profile, and Extensible Authentication Protocol specifications, this application specification satisfies typical network access services requirements. Then it defines the Diameter message Command-Codes.
The name is a play on words, derived from the RADIUS protocol, which is the predecessor a diameter is twice the radius.
When creating a request, the End-to-End Identifier is set to a locally unique value. The Hop-by-Hop Identifier is an unsigned bit integer field in network byte order that is used to match the requests with their answers as the same value in the request is used in the response. The authorization AVPs are further broken down by service type.
