After consulting our Area Directors, the decision is to close the WG as soon as the PIB is published (regardless of whether it is published as a Proposed Standard or otherwise, which is an IESG decision). We've decided to leave pending PDB work to be done in the "no diffserv WG mode" defined in RFC 3086. Thus draft-ietf-diffserv-pdb-ar-01.txt, and any other pending PDB definitions, will need to be recycled as individual submissions when the WG closes. Multicast is not covered in our charter, and the Area Directors have decided to refer draft-bless-diffserv-multicast-03.txt to the Routing Area. As a reminder, diffserv/intserv interworking is considered in the ISSLL WG, and future QOS signalling is considered in the NSIS WG.

It is my view that capabilities are abstractions of implementations. However, it is difficult to decide where to stop. It is fine to say that a router supports classification. But it is not that simple. A policy server (and I use the term very loosely :) would also like to know how many classifiers, whether ranges or lists are supported, and where classifiers can be placed in a datapath. There is far more complexity in representing capabilities than it appears. Therefore, my view of capabilities is that it is a convenient mechanism not for identifying the implementation, but for defining the hardware and software versioning that allows a policy server to implicitly know what configuration will and won't work. > It is even a mistake IMHO to invite network administrators to establish > policies their networks cannot deliver.

The challenge has always been that the RADIUS protocol has serious limitations in it's ability to support edge provisioning issues (security, QoS, Tunnels, etc.) Conversely, COPS PIBs, while offering more sophisticated provisioning capabilities have not adequately addressed the authentication and access management issues. The AccessBind PIB makes some strides towards addressing this, but it is by no means comprehensive. > >I would also like to reconsider Bert's points.

There is just no standard for it. There are lots of devices (CMTSes, GGSNs, and BRAS products) that are using COPS, SNMP, and RADIUS in proprietary ways to support the functionality I have described. The 3GPP have agreed on COPS-PR because they have this very need. This is not about whether the category exists but what the IETF will do (if anything) to provide a standard for supporting it. > >Second, I disagree that there is overlap with PIBs.

Comprehensive models are really complicated and have to consider many factors. Data models (MIBs, PIBs, MOFs, Schemas, etc.) represent behavioral interfaces. If the behavioral requirements are different for different parts of the network, different technologies, and different implementations, the model quickly turns into an excercise in boiling the ocean. My point was that the MIB and PIB were conceived to address provisioning of the core of the DiffServ network. Given the clear domination of CLI in this space, the model is not ideally suited for edge config either. > >Given the unique applicability of COPS-PR, PIBs should be defined > >specifically for this purpose and only this purpose. > > Which unique applicability of COPS-PR is this?

As long as we consider the larger question (config) rather than looking at a specific instance of the question (PIBs) I am fine with any answer. For me at least, the question is not what should be done with PIBs, but what should be done with config in general. When we have answered the second question the first one becomes easy. In the mean time all config related standards (Policy Framework, writable MIBs, and PIBs) should be treated consistently until we sort out the first question. > >We could also block the advancement of COPS-PR.

I have never seen him (or > Randy, for that matter) try to "block advancement". I believe Randy at least is still considering his position on this. However, Bert should be able to offer a pretty clear position on whether he is in favor of Experimental or Informational (which to me amounts to blocked advancement). _______________________________________________ diffserv mailing list diffserv@ietf.org https://www1.ietf.org/mailman/listinfo/diffserv Archive: http://www.ietf.org/mail-archive/working-groups/diffserv/current/maillist.html From daemon@optimus.ietf.org Mon Apr 8 06:57:37 2002 Received: from optimus.ietf.org (ietf.org [132.151.1.19] (may be forged)) by ietf.org (8.9.1a/8.9.1a) with ESMTP id GAA19935 for ; Mon, 8 Apr 2002 06:57:37 -0400 (EDT) Received: (from daemon@localhost) by optimus.ietf.org (8.9.1a/8.9.1) id GAA26103 for diffserv-archive@odin.ietf.org; Mon, 8 Apr 2002 06:57:39 -0400 (EDT) Received: from optimus.ietf.org (localhost [127.0.0.1]) by optimus.ietf.org (8.9.1a/8.9.1) with ESMTP id GAA25334; Mon, 8 Apr 2002 06:37:26 -0400 (EDT) Received: from ietf.org (odin [132.151.1.176]) by optimus.ietf.org (8.9.1a/8.9.1) with ESMTP id GAA25302 for ; Mon, 8 Apr 2002 06:37:21 -0400 (EDT) Received: from condor.uom.ac.mu ([202.60.7.11]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id GAA19643 for ; Mon, 8 Apr 2002 06:37:14 -0400 (EDT) Received: from uom.ac.mu ([172.22.24.61]) by condor.uom.ac.mu (Post.Office MTA v3.5.3 release 223 ID# 0-60726U1000L100S0V35) with SMTP id mu for ; Mon, 8 Apr 2002 14:35:53 +0400 Message-ID: <3CB17B78.5B51FB4D@uom.ac.mu> Date: Mon, 08 Apr 2002 15:14:00 +0400 From: sgoorah@uom.ac.mu (Goorah Shravan) Organization: University of Mauritius X-Mailer: Mozilla 4.72 [en] (Win98; I) X-Accept-Language: en MIME-Version: 1.0 To: diffserv@ietf.org Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Content-Transfer-Encoding: 7bit Subject: [Diffserv] QoS requirements of Applications Sender: diffserv-admin@ietf.org Errors-To: diffserv-admin@ietf.org X-Mailman-Version: 1.0 Precedence: bulk List-Id: Diffserv Discussion List X-BeenThere: diffserv@ietf.org Content-Transfer-Encoding: 7bit Hello there, I am looking for a compilation of QoS requirements in terms of Diffserv parameters (PHB = EF/AF/BE and Profile in bps) for applications (unicast and multicast).

Is their is any study relating these streaming applications with diffserv. 2.This question is more or less related to the first.Please refer to some research work which discusses relation between Audio& video qulaity and network performance.Some thoughts about this topic is also appreciated. 3.Is expedited forwarding only way to give guaranteed treatment to audio/video streaming applications 4.E-model of ITU-T estimates MOS by mapping voice quality with impairments like delay, signaling and user expection.Can we related these impairments with diffserv drop precedence for mapping streaming application with QoS.

I think you'll find that that's traffic at the edges, where hosts on LANs fight it out and academics have their kit and do their measurements. In the core, all these slower streams are aggregated, smoothing out individual peaks, and everything's running much nearer capacity.

This link should provide you with more information related to the usefulness of PIBs. The SDK also provides source code for a SPPI (RFC3159) compliant PIB Compiler/Client Control Interface Generator that integrates into the SDK. The SDK is at: http://www.intel.com/labs/manage/cops/ Hopefully, this demonstrates industry commitment to deliver quality and readily available tools for easy PIB development.

As such, the Internet is now moving from being a best-effort service provider, to a provider of assured service qualities. This requires the development of new protocols, both inside subnetworks, and on end-to-end levels.

A new and lightweight service paradigm, namely, the Differentiated Services (DiffServ) approach has been proposed by IETF and active research is underway to define architectures and strategies for QoS within the Internet. Several issues still need to be worked on, such as end-to-end service interworking, actual protocol mechanisms and implementation, classification and marking, the service level agreement and the service guarantees.

control, QoS routing, resource reservation, service provisioning, = etc.   The

Internet Engineering Task Force (IETF), as the main standard body = for IP

- End-to-end service interworking

- Congestion control strategies in DiffServ networks

- Active queue management

Can I join the seconders The problems is made more complicated in 3G UMTS by the presence of circuit switched traffic that gives an added degree of uncertainty at the acess layer. The admission control problem is not a trivial one partiularly with conflicting design objectives.
