I believe that this workshop is relevant to the diffserv community, so I'd appreciate it if you could circulate the CFP on the diffserv mailing list. -Venkat CALL FOR PAPERS The 14th International Workshop on Network and Operating Systems Support for Digital Audio and Video (NOSSDAV 2004)=20 June 16-18, 2004 --- Kinsale, County Cork, Ireland=20 http://www.nossdav.org/2004/ NOSSDAV 2004 will take place in Kinsale on the exceptionally scenic southern coast of Ireland. Kinsale is approximately a 20 minute drive outside Cork city, which is within easy reach of major European capitals and the east coast of the US. The workshop is sponsored by ACM SIG Multimedia (preliminary approval), Microsoft Research and Science Foundation Ireland, and is in cooperation with ACM SIGCOMM (preliminary approval). NOSSDAV invites submissions on all areas of multimedia, but strongly encourages submissions in newly emerging specialized areas such as networked games and peer-to-peer streaming. NOSSDAV 2004 will be run very much as a workshop with an emphasis on cutting-edge research and lively discussion. Papers grounded in high-quality experimental research based on prototype or real systems, including innovative experimental commercial designs and prototypes, as well as papers proposing new research directions for the community or calling into question existing conventional wisdom are particularly welcome. ***Student participation is strongly encouraged*** - supported by several student travel grants and registration fee rebates. Submissions should be no longer than 6 pages. The expectation is that papers accepted at the workshop will eventually lead to full-length papers at high-quality conferences or journals. The topics of interest include, but are not limited to: * Networked games * Peer-to-peer multimedia * Broadband streaming media content distribution * 3D multimedia and (networked) immersive environments * Wireless and ad-hoc network multimedia systems * Embedded multimedia devices (e.g., PVRs) * Multimedia security * Internet telephony * Sensory interactive applications * Digital rights management Deadlines: Paper registration deadline - February 23, 2004, (5pm EST) (*firm*)=20 Paper submission deadline - March 1, 2004, (5pm EST) (*firm*) Program Co-Chairs: Venkat Padmanabhan, Microsoft Research (USA)=20 Cormac Sreenan, University College Cork (Ireland) Email: nossdav2004-pcchairs@cs.ucc.ie Program Committee: Kevin Almeroth, UC Santa Barbara (USA) Ernst Biersack, Institut Eurecom (France) Phil Chou, Microsoft Research (USA) Christophe Diot, Intel Research (UK) Kevin Jeffay, UNC Chapel Hill (USA) Srinivasan Keshav, University of Waterloo (Canada) Sue Moon, KAIST (Korea) Reza Rejaie, University of Oregon (USA) Henning Schulzrinne, Columbia University (USA) Srinivasan Seshan, CMU (USA) Anees Shaikh, IBM Research (USA) Lars Wolf, TU Braunschweig (Germany) _______________________________________________ Diffserv-interest mailing list Diffserv-interest@ietf.org https://www1.ietf.org/mailman/listinfo/diffserv-interest From exim@www1.ietf.org Wed Dec 3 05:15:21 2003 Received: from optimus.ietf.org ([132.151.1.19]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id FAA08329 for ; Wed, 3 Dec 2003 05:15:21 -0500 (EST) Received: from localhost.localdomain ([127.0.0.1] helo=www1.ietf.org) by optimus.ietf.org with esmtp (Exim 4.20) id 1ARU2E-0004cW-VQ for diffserv-interest-archive@odin.ietf.org; Wed, 03 Dec 2003 05:15:07 -0500 Received: (from exim@localhost) by www1.ietf.org (8.12.8/8.12.8/Submit) id hB3AF6uF017737 for diffserv-interest-archive@odin.ietf.org; Wed, 3 Dec 2003 05:15:06 -0500 Received: from localhost.localdomain ([127.0.0.1] helo=www1.ietf.org) by optimus.ietf.org with esmtp (Exim 4.20) id 1ARU2A-0004bx-EV; Wed, 03 Dec 2003 05:15:02 -0500 Received: from odin.ietf.org ([132.151.1.176] helo=ietf.org) by optimus.ietf.org with esmtp (Exim 4.20) id 1ARU27-0004bi-Jt for diffserv-interest@optimus.ietf.org; Wed, 03 Dec 2003 05:14:59 -0500 Received: from ietf-mx (ietf-mx.ietf.org [132.151.6.1]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id FAA08322 for ; Wed, 3 Dec 2003 05:14:43 -0500 (EST) Received: from ietf-mx ([132.151.6.1]) by ietf-mx with esmtp (Exim 4.12) id 1ARU24-0005Uw-00 for diffserv-interest@ietf.org; Wed, 03 Dec 2003 05:14:56 -0500 Received: from mtagate4.de.ibm.com ([195.212.29.153]) by ietf-mx with esmtp (Exim 4.12) id 1ARU23-0005Ub-00 for diffserv-interest@ietf.org; Wed, 03 Dec 2003 05:14:55 -0500 Received: from d12relay01.megacenter.de.ibm.com (d12relay01.megacenter.de.ibm.com [9.149.165.180] (may be forged)) by mtagate4.de.ibm.com (8.12.10/8.12.10) with ESMTP id hB3AEOPg068514 for ; Wed, 3 Dec 2003 10:14:24 GMT Received: from collon.zurich.ibm.com (collon.zurich.ibm.com [9.4.16.143]) by d12relay01.megacenter.de.ibm.com (8.12.9/NCO/VER6.6) with ESMTP id hB3AEOG4283202 for ; Wed, 3 Dec 2003 11:14:24 +0100 Received: from zurich.ibm.com ([9.145.247.80]) by collon.zurich.ibm.com (AIX4.3/8.9.3p2/8.9.3) with ESMTP id LAA39290 for ; Wed, 3 Dec 2003 11:14:21 +0100 Message-ID: <3FCDB74C.F1355AB9@zurich.ibm.com> Date: Wed, 03 Dec 2003 11:13:32 +0100 From: Brian E Carpenter Organization: IBM X-Mailer: Mozilla 4.79 [en] (Windows NT 5.0; U) X-Accept-Language: en,fr,de MIME-Version: 1.0 To: diffserv interest Content-Type: multipart/mixed; boundary="------------78105322E924281DCF7000FC" Subject: [Diffserv-interest] [Fwd: I-D ACTION:draft-baker-tsvwg-mlef-concerns-00.txt] Sender: diffserv-interest-admin@ietf.org Errors-To: diffserv-interest-admin@ietf.org X-BeenThere: diffserv-interest@ietf.org X-Mailman-Version: 2.0.12 Precedence: bulk List-Unsubscribe: , List-Id: Differentiated services general discussion List-Post: List-Help: List-Subscribe: , This is a multi-part message in MIME format. --------------78105322E924281DCF7000FC Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit -------- Original Message -------- Subject: I-D ACTION:draft-baker-tsvwg-mlef-concerns-00.txt Date: Tue, 02 Dec 2003 15:35:12 -0500 From: Internet-Drafts@ietf.org Reply-To: Internet-Drafts@ietf.org To: IETF-Announce: ; A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : MLEF Considered Harmful Author(s) : F. Baker Filename : draft-baker-tsvwg-mlef-concerns-00.txt Pages : 19 Date : 2003-12-2 The Defense Information Systems Agency of the United States Department of Defense, with is contractors, has proposed a service architecture for military (NATO and related agencies) telephone systems. This is called the Assured Service, and is defined in two documents: 'Architecture for Assured Service Capabilities in Voice over IP' and 'Requirements for Assured Service Capabilities in Voice over IP'. Responding to these are four documents: 'Reason Header Field for the Session Initiation Protocol', 'Extending the Session Initiation Protocol Reason Header to account for Preemption Events', 'Communications Resource Priority for the Session Initiation Protocol', and the 'Multi-Level Expedited Forwarding Per Hop Behavior' (MLEF PHB). MLEF, as currently defined, has serious problems, which this draft seeks to discuss. A URL for this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-baker-tsvwg-mlef-concerns-00.txt To remove yourself from the IETF Announcement list, send a message to ietf-announce-request with the word unsubscribe in the body of the message.

NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft. --------------78105322E924281DCF7000FC Content-Type: Message/External-body; name="draft-baker-tsvwg-mlef-concerns-00.txt" Content-Disposition: inline; filename="draft-baker-tsvwg-mlef-concerns-00.txt" Content-Transfer-Encoding: 7bit Content-Type: text/plain Content-ID: <2003-12-2154348.I-D@ietf.org> --------------78105322E924281DCF7000FC-- _______________________________________________ Diffserv-interest mailing list Diffserv-interest@ietf.org https://www1.ietf.org/mailman/listinfo/diffserv-interest From exim@www1.ietf.org Tue Dec 9 04:05:24 2003 Received: from optimus.ietf.org ([132.151.1.19]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id EAA18846 for ; Tue, 9 Dec 2003 04:05:24 -0500 (EST) Received: from localhost.localdomain ([127.0.0.1] helo=www1.ietf.org) by optimus.ietf.org with esmtp (Exim 4.20) id 1ATdnp-0004IU-LU for diffserv-interest-archive@odin.ietf.org; Tue, 09 Dec 2003 04:05:10 -0500 Received: (from exim@localhost) by www1.ietf.org (8.12.8/8.12.8/Submit) id hB9959Ew016486 for diffserv-interest-archive@odin.ietf.org; Tue, 9 Dec 2003 04:05:09 -0500 Received: from localhost.localdomain ([127.0.0.1] helo=www1.ietf.org) by optimus.ietf.org with esmtp (Exim 4.20) id 1ATdnj-0004Hi-KY; Tue, 09 Dec 2003 04:05:03 -0500 Received: from odin.ietf.org ([132.151.1.176] helo=ietf.org) by optimus.ietf.org with esmtp (Exim 4.20) id 1ATdmr-0004Gd-F7 for diffserv-interest@optimus.ietf.org; Tue, 09 Dec 2003 04:04:09 -0500 Received: from ietf-mx (ietf-mx.ietf.org [132.151.6.1]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id EAA18781 for ; Tue, 9 Dec 2003 04:03:53 -0500 (EST) Received: from ietf-mx ([132.151.6.1]) by ietf-mx with esmtp (Exim 4.12) id 1ATdmo-00048X-00 for diffserv-interest@ietf.org; Tue, 09 Dec 2003 04:04:06 -0500 Received: from mtagate3.de.ibm.com ([195.212.29.152]) by ietf-mx with esmtp (Exim 4.12) id 1ATdmn-00048I-00 for diffserv-interest@ietf.org; Tue, 09 Dec 2003 04:04:05 -0500 Received: from d12relay01.megacenter.de.ibm.com (d12relay01.megacenter.de.ibm.com [9.149.165.180] (may be forged)) by mtagate3.de.ibm.com (8.12.10/8.12.10) with ESMTP id hB993Zn0069628 for ; Tue, 9 Dec 2003 09:03:35 GMT Received: from collon.zurich.ibm.com (collon.zurich.ibm.com [9.4.16.143]) by d12relay01.megacenter.de.ibm.com (8.12.9/NCO/VER6.6) with ESMTP id hB993WUU219328 for ; Tue, 9 Dec 2003 10:03:35 +0100 Received: from zurich.ibm.com ([9.145.175.184]) by collon.zurich.ibm.com (AIX4.3/8.9.3p2/8.9.3) with ESMTP id KAA32464 for ; Tue, 9 Dec 2003 10:03:30 +0100 Message-ID: <3FD58FAE.535C054C@zurich.ibm.com> Date: Tue, 09 Dec 2003 10:02:38 +0100 From: Brian E Carpenter Organization: IBM X-Mailer: Mozilla 4.79 [en] (Windows NT 5.0; U) X-Accept-Language: en,fr,de MIME-Version: 1.0 To: diffserv-interest@ietf.org Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Content-Transfer-Encoding: 7bit Subject: [Diffserv-interest] [Fwd: Protocol Action: 'The Differentiated Services Configuration MIB' to Proposed Standard] Sender: diffserv-interest-admin@ietf.org Errors-To: diffserv-interest-admin@ietf.org X-BeenThere: diffserv-interest@ietf.org X-Mailman-Version: 2.0.12 Precedence: bulk List-Unsubscribe: , List-Id: Differentiated services general discussion List-Post: List-Help: List-Subscribe: , Content-Transfer-Encoding: 7bit -------- Original Message -------- Subject: Protocol Action: 'The Differentiated Services Configuration MIB' to Proposed Standard Date: Mon, 08 Dec 2003 11:48:55 -0500 From: The IESG To: IETF-Announce:; CC: Internet Architecture Board ,RFC Editor , The IESG has approved following document: - 'The Differentiated Services Configuration MIB ' as a Proposed Standard This document is the product of the Configuration Management with SNMP Working Group. The IESG contact person is Bert Wijnen. Technical Summary This memo describes a MIB module that provides a conceptual layer between high-level "network-wide" policy definitions that effect configuration of the Differentiated Services (diffserv) subsystem and the instance-specific information that would include such details as the parameters for all the queues associated with each interface in a system. This essentially provides an interface for configuring differentiated services at a conceptually higher layer than that of the Differentiated Services MIB. Working Group Summary The working group has consensus that this document be published as a Proposed Standard. The WG worked extensively with people from the DIFFSERV WG to make sure that this document and RFC3289 are in sync and can be used together. Protocol Quality This document was reviewed for the IESG by Bert Wijnen. _______________________________________________ Diffserv-interest mailing list Diffserv-interest@ietf.org https://www1.ietf.org/mailman/listinfo/diffserv-interest From exim@www1.ietf.org Thu Dec 18 20:31:37 2003 Received: from optimus.ietf.org ([132.151.1.19]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id UAA04984 for ; Thu, 18 Dec 2003 20:31:37 -0500 (EST) Received: from localhost.localdomain ([127.0.0.1] helo=www1.ietf.org) by optimus.ietf.org with esmtp (Exim 4.20) id 1AX9Tw-0005ki-IF for diffserv-interest-archive@odin.ietf.org; Thu, 18 Dec 2003 20:31:08 -0500 Received: (from exim@localhost) by www1.ietf.org (8.12.8/8.12.8/Submit) id hBJ1V8XQ022106 for diffserv-interest-archive@odin.ietf.org; Thu, 18 Dec 2003 20:31:08 -0500 Received: from localhost.localdomain ([127.0.0.1] helo=www1.ietf.org) by optimus.ietf.org with esmtp (Exim 4.20) id 1AX9Tr-0005jT-Vq; Thu, 18 Dec 2003 20:31:03 -0500 Received: from odin.ietf.org ([132.151.1.176] helo=ietf.org) by optimus.ietf.org with esmtp (Exim 4.20) id 1AX9TX-0005iD-9v for diffserv-interest@optimus.ietf.org; Thu, 18 Dec 2003 20:30:43 -0500 Received: from ietf-mx (ietf-mx.ietf.org [132.151.6.1]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id UAA04905 for ; Thu, 18 Dec 2003 20:30:41 -0500 (EST) Received: from ietf-mx ([132.151.6.1]) by ietf-mx with esmtp (Exim 4.12) id 1AX9TV-0006NK-00 for diffserv-interest@ietf.org; Thu, 18 Dec 2003 20:30:41 -0500 Received: from exim by ietf-mx with spam-scanned (Exim 4.12) id 1AX9TT-0006ND-00 for diffserv-interest@ietf.org; Thu, 18 Dec 2003 20:30:40 -0500 Received: from iramx2.ira.uni-karlsruhe.de ([141.3.10.81]) by ietf-mx with esmtp (Exim 4.12) id 1AX9TT-0006MA-00 for diffserv-interest@ietf.org; Thu, 18 Dec 2003 20:30:39 -0500 Received: from irams1.ira.uni-karlsruhe.de ([141.3.10.5] helo=irams1.ira.uka.de) by iramx2.ira.uni-karlsruhe.de with esmtp (Exim 3.30 #10 (Debian)) id 1AX9T2-00035g-00 for ; Fri, 19 Dec 2003 02:30:13 +0100 Received: from i72ms1.tm.uni-karlsruhe.de ([141.3.70.16] helo=smtp.ipv6.tm.uni-karlsruhe.de ident=8) by irams1.ira.uka.de with esmtp (Exim 3.30 #7 ) for id 1AX9T2-0002bq-00; Fri, 19 Dec 2003 02:30:12 +0100 Received: from vorta.ipv6.tm.uni-karlsruhe.de ([2001:638:204:6:2e0:29ff:fe3e:c87] ident=mail) by smtp.ipv6.tm.uni-karlsruhe.de with esmtp (TLSv1:DES-CBC3-SHA:168) (Exim 4.12) id 1AX9Sz-0003C1-00 for diffserv-interest@ietf.org; Fri, 19 Dec 2003 02:30:09 +0100 Received: from localhost ([::1] helo=vorta.ipv6.tm.uni-karlsruhe.de ident=bless) by vorta.ipv6.tm.uni-karlsruhe.de with smtp (Exim 4.05) id 1AX9Sx-000307-00 for diffserv-interest@ietf.org; Fri, 19 Dec 2003 02:30:07 +0100 Date: Fri, 19 Dec 2003 02:30:07 +0100 From: Roland Bless To: diffserv interest Message-Id: <20031219023007.7a7a7253.bless@tm.uka.de> Organization: Institute of Telematics, University of Karlsruhe X-Mailer: Sylpheed version 0.9.6claws (GTK+ 1.2.10; i686-pc-linux-gnu) Mime-Version: 1.0 Content-Type: multipart/mixed; boundary="Multipart=_Fri__19_Dec_2003_02_30_07_+0100_R6RTu+orCUpxqOMb" X-Spam-Checker-Version: SpamAssassin 2.60 (1.212-2003-09-23-exp) on ietf-mx.ietf.org X-Spam-Status: No, hits=0.0 required=5.0 tests=none autolearn=no version=2.60 Subject: [Diffserv-interest] Fw: RFC 3662 on A Lower Effort Per-Domain Behavior (PDB) for Differentiated Services Sender: diffserv-interest-admin@ietf.org Errors-To: diffserv-interest-admin@ietf.org X-BeenThere: diffserv-interest@ietf.org X-Mailman-Version: 2.0.12 Precedence: bulk List-Unsubscribe: , List-Id: Differentiated services general discussion List-Post: List-Help: List-Subscribe: , This is a multi-part message in MIME format. --Multipart=_Fri__19_Dec_2003_02_30_07_+0100_R6RTu+orCUpxqOMb Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Hi, FYI: this is a first draft in the PDB series.

In this sense, the proposed PDB's traffic is forwarded with a "lower" priority than the normal "best-effort" Internet traffic, thus the PDB is called "Lower Effort" (LE). Use of this PDB permits a network operator to strictly limit the effect of its traffic on "best-effort"/"normal" or all other Internet traffic. This document gives some example uses, but does not propose constraining the PDB's use to any particular type of traffic. This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. This announcement is sent to the IETF list and the RFC-DIST list. Requests to be added to or deleted from the IETF distribution list should be sent to IETF-REQUEST@IETF.ORG. Requests to be added to or deleted from the RFC-DIST distribution list should be sent to RFC-DIST-REQUEST@RFC-EDITOR.ORG. Details on obtaining RFCs via FTP or EMAIL may be obtained by sending an EMAIL message to rfc-info@RFC-EDITOR.ORG with the message body help: ways_to_get_rfcs. For example: To: rfc-info@RFC-EDITOR.ORG Subject: getting rfcs help: ways_to_get_rfcs Requests for special distribution should be addressed to either the author of the RFC in question, or to RFC-Manager@RFC-EDITOR.ORG. Unless specifically noted otherwise on the RFC itself, all RFCs are for unlimited distribution.echo Submissions for Requests for Comments should be sent to RFC-EDITOR@RFC-EDITOR.ORG.

You'll ask: Why not? (It has been said so many times before:) DSCPs have no structure, so CS1=001000 is not in AF1x={001010,001100,001110} (you should never apply any bit mask to the DSCP, because all six bits must be considered).

See also RFC 2597: 7. Interactions with Other PHB Groups The AF codepoint mappings recommended above do not interfere with the local use spaces nor the Class Selector codepoints recommended in [Nichols]. > You'll ask: Why not?

Therefore, Class Selector Codepoints have always 000 in the lower three bits, so they do not interfere with any recommended AF DSCP values.
