Abort-Session-Answer ..............................114 8.6. End-to-End Identifier[edit] The End-to-End Identifier is an unsigned 32-bit integer field (in network byte order) that is used to detect duplicate messages along with the combination of the Origin-Host AVP.

Transition support While Diameter does not share a common protocol data unit (PDU) with RADIUS, considerable effort has been expended in enabling backward compatibility with RADIUS so that the two protocols Relaying and Proxying Requests .....................79 6.2. Diameter clients MUST support the base protocol, which includes accounting. Device-Watchdog-Answer....................... 64 5.5.3.

Failed-AVP AVP ............................................96 7.6. Multi-sessions are tracked by using the Acct-Multi-Session-Id. Fajardo, et al. See Section 6.1.8 for redirection guidelines.

The idea of returning failure codes with 200 OK status is so bad that even the SOAP community did not make this mistake. 200 responses are cacheable, and the semantic is The Diameter protocol also supports server-initiated messages, such as a request to abort service to a particular user. 1.1.1. A Realm Routing Table Entry contains the following fields: Realm Name This is the field that is typically used as a primary key in the routing table lookups. Diameter Protocol Pdf AVP Header............................................ 39 4.1.1.

The Diameter protocol requires that agents maintain transaction state, which is used for failover purposes. Introduction ....................................................7 1.1.

Diameter Protocol Tutorial The example provided in Figure 3 depicts a request issued from the access device, NAS, for the user [email protected] See Section 5.2 for more information on peer discovery. Two Diameter applications are defined by companion documents: NASREQ [NASREQ], Calhoun, et al.

Diameter Protocol Rfc

Packet Format[edit] 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. This routing decision is performed using a list of supported realms and known peers. Lync No More Subscription With Focus For example, where TLS or IPsec transmission- level security is sufficient, there may be no need for end-to-end security. Diameter Error Codes The values 16777214 and 16777215 (hex 0xFFFFFE and 0xFFFFFF) are reserved for experimental and testing purposes.

Informative References ..................................144 Appendix A. Reservation of Rights. Role of Diameter Agents In addition to clients and servers, the Diameter protocol introduces relay, proxy, redirect, and translation agents, each of which is defined in Section 1.2. Server-Initiated Re-Auth.............................. 101 8.3.1. Diameter Protocol Call Flow

Examples are removal of obsolete types, fixes to the state machine, clarification of the election process, message validation, fixes to Failed-AVP and Result-Code AVP values, etc. Standards Track [Page 16] RFC 3588 Diameter Based Protocol September 2003 Real-time Accounting Real-time accounting involves the processing of information on resource usage within a defined time window. Role of Diameter Agents ...................................28 2.8.1. Once accepted by the server, both the client and the server are aware of the session.

Option 4: Return an XML Error Document In this scenario, the web service always returns an HTTP Status Code of 200, but also includes an XML document containing an application specific Diameter Protocol Explained Transport Failure Algorithm ........................67 5.5.4. Is this page helpful?

RFCs[edit] The Diameter protocol is currently defined in the following IETF RFCs: Obsolete RFCs are indicated with strikethrough text. # Title Date published Related article Obsoleted by Notes RFC 3588 Diameter o Routing, relaying, proxying, and redirecting of Diameter messages through a server hierarchy The Diameter base protocol satisfies the minimum requirements for a AAA protocol, as specified by [RFC2989]. Accounting Session State Machine .........................104 Fajardo, et al. Diameter Avp Attribute-Name Code Data Type Acct-Interim-Interval 85 Unsigned32 Accounting-Realtime-Required 483 Enumerated Acct-Multi-Session-Id 50 UTF8String Accounting-Record-Number 485 Unsigned32 Accounting-Record-Type 480 Enumerated Accounting-Session-Id 44 OctetString Accounting-Sub-Session-Id 287 Unsigned64 Acct-Application-Id 259 Unsigned32 Auth-Application-Id 258 Unsigned32

For AVPs of type Enumerated, an application may require a new value to communicate some service-specific information. As described in [RFC2975], this is a major issue in accounting, where packet loss may translate directly into revenue loss. Session-Server-Failover AVP Values........... 130 11.4.6. After that the transport connection can be disconnected.

Otherwise, an error is returned with the Result-Code AVP set to DIAMETER_UNABLE_TO_DELIVER. 2.8. When connecting to a peer and either zero or more transports are specified, TLS SHOULD be tried first, followed by DTLS, then by TCP, and finally by SCTP. Standards Track [Page 19] RFC 6733 Diameter Base Protocol October 2012 M-bit Setting An AVP with the M-bit in the MUST column of the AVP flag table is added to an Sessions This section attempts to provide the reader with an understanding of the difference between connection and session, which are terms used extensively throughout this document.
