Internet-Draft The Diameter Document Set July 2009
1. Introduction
This document is intended to provide a stable reference to the
dynamic set of RFCs describing the Diameter protocol. As such, it is
expected that it will be updated/obsoleted shortly after any new
Diameter-related RFC is published.
2. Terminology
AAA
Authentication, Authorization and Accounting
3. The Diameter Document Set
The Diameter document set has two components:
o products of the IETF itself, generally Standards-Track [RFC2026]
RFCs
and
o RFCs relating to Diameter-based protocols developed outside the
IETF.
3.1. IETF Documents
Currently, the IETF Diameter specification consists of the Base
protocol specification [RFC3588], Transport Profile [RFC3539] and
several applications: Mobile IPv4 [RFC4004], Network Access Server
(NASREQ) [RFC4005], Credit Control [RFC4006], Extensible
Authentication Protocol (EAP) [RFC4072], Session Initiation Protocol
(SIP) [RFC4740], and Mobile IPv6 [RFC5447].
The following subsections briefly summarize the documents included in
the present set.
3.1.1. Diameter Base Protocol
The Base Protocol document [RFC3588] defines the fundamental protocol
specification for Diameter AAA, which includes support for
accounting.
3.1.2. AAA Transport Profile
The Transport Profile document [RFC3539] discusses transport layer
issues that arise with AAA protocols and contains recommendations on

Internet-Draft The Diameter Document Set July 2009
how to overcome these issues. This document also defines the
Diameter failover algorithm and state machine.
3.1.3. Applications
3.1.3.1. Mobile IPv4
The Mobile IPv4 [RFC4004] document defines a Diameter application
that allows a Diameter server to perform AAA functions for MobileIPv4
services to a mobile node.
3.1.3.2. Network Access Server (NASREQ)
This document [RFC4005] describes the Diameter protocol application
used for AAA services in the Network Access Server (NAS) environment.
When combined with the Diameter Base protocol [RFC3588], Transport
Profile [RFC3539], and EAP [RFC4072] specifications, this application
specification satisfies typical network access service requirements.
3.1.3.3. Diameter Credit Control
This document [RFC4006] specifies a Diameter application that can be
used to implement real-time credit-control for a variety of end user
services such as network access, Session Initiation Protocol (SIP)
[RFC3261] services, messaging services, and download services.
3.1.3.4. EAP
This document [RFC4072] defines the Diameter Command-Codes and AVPs
necessary to carry EAP packets between a Network Access Server (NAS)
and a back-end authentication server.
3.1.3.5. SIP
This application [RFC4740] is designed to be used in conjunction with
SIP and provides a Diameter client co-located with a SIP server, with
the ability to request the authentication of users and authorization
of SIP resources usage from a Diameter server.
3.1.3.6. Mobile IPv6
This document [RFC5447] describes Mobile IPv6 bootstrapping using the
Diameter Network Access Server to home AAA server interface.
3.2. Other RFCs
Zorn Expires January 6, 2010 [Page 4]
Internet-Draft The Diameter Document Set July 2009
3.2.1. 3GPP EPS Command Codes
This document [RFC5516] registers a set of Diameter Command Codes to
be used in new vendor-specific Diameter applications defined for the
Third Generation Partnership Project (3GPP) Evolved Packet System
(EPS), specifically those related to the Mobile Management Entity
(MME) and Serving GPRS (General Packet Radio Service) Support Node
(SGSN) interfaces in the architecture for the Evolved 3GPP Packet
Switched Domain.
3.2.2. ITU-T Rw Policy Enforcement Interface
This document [RFC5431] describes the need for a new pair of IANA
Diameter Command Codes to be used in a vendor-specific new
application, namely for the ITU-T Rec. Q.3303.3 - Rw interface used
to send a request/response for authorizing network Quality of Service
(QoS) resources and policy enforcement in a network element, as one
of the recommendations of the International Telecommunication Union -
Telecommunication Standardization Sector (ITU-T).
3.2.3. Diameter Policy Processing Application
This document [RFC5224] describes the need for a Diameter Command
Code to be used in a vendor-specific application for invocation of
Policy Processing (Policy Evaluation, or Evaluation and Enforcement).
This application is one of the implementations of the Open Mobile
Alliance (OMA) Policy Evaluation, Enforcement and Management (PEEM)
enabler.
3.2.4. 3GPP Release 5 Command Codes
This document [RFC3589] describes the IANA allocation of a block of
Diameter Command Codes for the Third Generation Partnership Project
(3GPP) Release 5.
4. Security Considerations
This document has no relevance for security.
5. IANA considerations
This document makes no requests of IANA.
