Abstract
This document 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).

RFC 5431 ITU-T Rw Interface March 2009
1. Introduction
This document summarizes the use of Diameter codes in a newly defined
realization of a specification for authorizing network QoS resources
and policy enforcement [Q.3303.3]. A new pair of Command Codes have
been assigned by IANA. This document summarizes the uses of newly
defined Diameter codes (Command Codes, AVP, vendor-specific
application id). When combined with the Diameter Base protocol, this
application's specification [Q.3303.3] satisfies the requirements of
[Y.2111] of the International Telecommunication Union -
Telecommunication Standardization Sector (ITU-T) to send a request
and receive a response for controlling the policy enforcement.
The Diameter realization of this application assumes the use of the
Diameter Base protocol, as per RFC 3588, and extends it only for a
specific application using a vendor-id (ITU-T), a vendor-specific
application ID (16777256), a new Command Code (315), and new
attribute-value pairs (AVPs), which are defined in the vendor-
specific namespace.
This application is used to authorize network QoS resources and
policy enforcement (including the amount of bandwidth, QoS class, and
traffic flow processing) as an extension of the Diameter application
[RFC4006]. The request is based on the Diameter extensibility
discussions in the DIME WG that led to the conclusion that it is
better to define new Command Codes whenever the ABNF of a command is
modified by adding, removing, or semantically changing a required AVP
in order to avoid interoperability problems. The document is
utilizing authorization and accounting functionality, and the entire
exchange is related to users utilizing applications that require QoS
treatment. This approach is consistent with the practice and
experience gained since the publication of [RFC3588] (see for example
[RFC5224]), which is now under revision by the DIME Working Group who
will provide a revised set of recommendations and procedures for IANA
considerations [DIME].
2. Terminology
In the base Diameter specification [RFC3588], Section 1.4 defines
most of the terminology used in this document. Additionally, the
terms and acronyms defined in Section 3 and Section 4 of [Q.3303.3]
are used in this document.
