Dear all,

I noticed that this draft does not seem to be aligned with draft-ietf-dime-qos-attributes regarding the example given therein.

This is due to the fact, that draft-ietf-dime-diameter-qos-15.txt does not cover "online charging", only "accounting".  In my view, the term "accounting"  is more  or less synonomous with the term "offline-charging". 

Because the draft-ietf-dime-qos-attributes contains an example, which is based on online-charging using DCCA (Diameter Credit Control Application), I believe this apparent lack of coverage for online charging should be fixed.

Proposed solution to fix this issue:

In draft-ietf-dime-diameter-qos-15.txt change the title of chapter 9 from "accounting" to "accounting and charging", and add a section that describes, how DCCA may be used to charge for QoS, e.g. by referring to the example given in draft-ietf-dime-qos-attributes.

Alternatively, add a separate chapter 10 with title: "online charging", in which the interworking with DCCA should be described at least at a high level, potentially also referring to the example given in draft-ietf-dime-qos-attributes.

Betreff: [Dime] I-D Action:draft-ietf-dime-diameter-qos-15.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Diameter Maintenance and Extensions Working Group of the IETF.


	Title           : Diameter Quality of Service Application
	Author(s)       : D. Sun, et al.
	Filename        : draft-ietf-dime-diameter-qos-15.txt
	Pages           : 58
	Date            : 2010-03-07

This document describes the framework, messages and procedures for the Diameter Quality of Service (QoS) application.  The Diameter QoS application allows network elements to interact with Diameter servers when allocating QoS resources in the network.  In particular, two modes of operation, namely "Pull" and "Push", are defined.
