Our options are to either complete the current work and close this WG, or to propose a new Charter for 2007. At the last IETF meeting in San Diego, several topics were raised as potential WG items that were outside the current WG Charter, and that could be suitable for re-chartering. The currently proposed changes include: * Removal of the WG deliverable defining a new IP Address Resolution (AR) protocol - current comments suggest there is no consensus to progress this work item, and energy was instead devoted to completion of the informational draft, now with the IESG. * Addition of a WG deliverable to define a set of extension headers for ULE that would allow convergence with the Generic Stream Encapsulation (GSE) currently being defined by the DVB Technical Module. * Addition of a WG deliverable to define security extension headers for ULE - subject to progression of the ULE Security Requirements draft. * Addition of work items to define a set of documents defining a framework and profiles that enable ULE and GSE to support header compression. This email starts an open call for ideas. Comments and feedback on the above proposals are welcome, specifically, are there issues that should not be addressed? Are there topics that should also be included? Would anyone be willing to work to define the scope of any of these proposals in a form that could be suitable for submission to the WG and IESG?

This particular draft was introduced to support a standard in preparation by the DVB Forum. The aim is to make the 2nd Generation Physical Layer present an interface via the Generic Stream Encapsulation that is consistent with ULE (e.g. uses the IANA registry), so that both can benefit from common extension modules: header compression, etc (should these be defined). PLEASE DO read the draft below and offer email comments on the suitability or progression to an RFC and the technical content. ALL comments are welcome. Email received before the 25th January 2007 will be used to inform the decision about whether to make this a WG Draft. WG documents should no longer be regarded as the property of the individuals who originally authored them - the working group as a whole must decide how they are shaped, and to see the document to a successful conclusion. If adopted, the Internet Draft will be renamed to start with the filename draft-ietf-ipdvb..., and will be listed on the IETF web page for this WG.

I read your draft carefully and found it very interesting. However, I have the feeling that MPEG-2 TS is gradually abandoned and we=20 are paving towards an "all-IP" environment. The introduction of "generic stream" shows exactly this tendency, and I=20 believe that the same philosophy is to be followed in the 2nd generation=20 terrestrial specs also (DVB-T2). Surely, providing a support for TS packets encapsulation within GSE or=20 ULE might provide a backwards-compatibility, but IMHO it is of=20 questionable usability. MPEG-2 TS packets can be directly mapped in a S2=20 BBframe, without the use of extra overhead. At NCSR "Demokritos", we have a strong experience in IP/DVB and are=20 currently leading a European research activity which is to investigate=20 DVB-T2. In the latter, our team is devoted to research regarding=20 baseband formatting and upper-layer issues. My proposal: we can go on with your draft, since it strengthens the role=20 of GSE and ULE, making them more flexible. Indeed, the feature of=20 grouping data belonging to the same NPA is quite attractive. But I believe it is also important to look into how the ipdvb WG can=20 benefit from the advance of next-generation terrestrial standards.=20 Looking towards the "shutoff" of the MPEG-2 TS, possible issues for=20 research could be: - the full migration of the MPEG signalling (PSI) to IP/GSE level - the transfer of the DVB-H Time Slicing feature in IP/GSE level - the transfer of the transport-layer FEC (MPE-FEC) in IP/GSE level. and generally any issue which may stem from the use of Next-gen DVB as a=20 "transmission system for broadcasting IP datagrams" I would be more than willing to participate in any activity covering=20 such issues.

This particular draft was introduced to support a standard in=20 preparation by the DVB Forum. The aim is to make the 2nd Generation=20 Physical Layer present an interface via the Generic Stream Encapsulation=20 that is consistent with ULE (e.g. uses the IANA registry), so that both=20 can benefit from common extension modules: header compression, etc=20 (should these be defined). PLEASE DO read the draft below and offer email comments on the=20 suitability or progression to an RFC and the technical content. ALL=20 comments are welcome. Email received before the 25th January 2007 will=20 be used to inform the decision about whether to make this a WG Draft. WG documents should no longer be regarded as the property of the=20 individuals who originally authored them - the working group as a whole=20 must decide how they are shaped, and to see the document to a successful=20 conclusion. If adopted, the Internet Draft will be renamed to start with=20 the filename draft-ietf-ipdvb..., and will be listed on the IETF web=20 page for this WG. Best wishes, Gorry Fairhurst (ipdvb WG Chair) ---- Title : Extension Formats for Unidirectional Link Encapsulation (ULE)=20 and the Generic Stream Encapsulation (GSE) Author(s) : B. Collini-Nocker, G. Fairhurst Filename : draft-fairhurst-ipdvb-ule-ext-01.txt Date : 2007-1-11 This document describes a set of Extension Headers for the Unidirectional Lightweight Encapsulation (ULE). The Extension Header formats defined in this document provide new extensions that are common extensions to both ULE and the Generic Stream Encapsulation (GSE) defined by the second generation framing structure DVB-S2 standard (Channel coding and modulation systems for Broadcasting, Interactive Services, News Gathering and other broadband satellite applications).

I strongly believe that the ipdvb WG should adopt this draft. I also have a few comments(C)/suggestions(S) (see below). === (S.1) Regarding the PDU-Concat Extension: Maybe we can somehow use the (currently unused) most-significant bit in the first byte of they PDU-Length field? Of course, as nothing comes for free, every possible use of it will complicate the receiver processing. Nevertheless, we should consider it. My suggestions are: (a) It could be used to selectively enable a type field for each concatenated PDU, i.e. sort of "Type Field present indicator" (denoted by T). Of course it could also be an "absent indicator" ;-). From now on, I'll denote the PDU-Length field along with the optional type field as "concat header". The first concat header must have T=1 to indicate the type of the payload. After that one, if in subsequent concat headers T=0 then the the type field is omitted and the type is the same as indicated in the last concat header which had a type field (T=1). This also gives us the option to use extension headers in concatenated PDUs. The question is if we should allow them. I might add that using the T-bit would make the CONCAT-PDU-Type of the current draft version unnecessary. I also discussed this point with Gorry. It would be glad if we could get some comments on this one. (b) We could also use the MSbit for padding purposes, i.e. to achieve alignment (e.g. 2- or 4-byte) for the concatenated PDUs. The bit (P) would then control the presence of a padding control byte right after the PDU-Length field. The content of this padding control byte (PDU-Pad) is interpreted as the number of (additional) padding bytes (containing the hexadecimal value 0xff) preceding the start of the concatenated PDU. Example: If P=1 and the PDU-Pad field has a value of 2, this means that 2 bytes of padding follow the padding control field. This means that in total the PDU is padded by 3 bytes (including PDU-Pad). If PDU-Pad=0, then we've a 1-byte of padding. (S.2) Regarding the TS-Concat Extension In section 3.1 it might be more clear to refer to the number of TS packets contained in the SNDU by name, e.g. TS-Count, defined as TS-Count := (Length-10+D*6) / 188 (S.3) The figures on page 9 and 10 may suggest that the concatenated PDUs are aligned, but in fact they're not. (C.4) Regarding the "Summary" section (4) I never heard the term "Next_Header options" before. (C.5) Typos Page 3: > to this document. GSE maintains a design philosophy that presents a > common network interface to that of ULE and uses a similar > construction for SNDUs ^--- A dot is missing Page 8: > The base header contains the Length of the entire SNDU. This carries > the value of the combined length of all PDUs to be encapsulated, > including each set of encapsulation headers. The base header also > caries a 16-bit ULE Type field. ^--- Don't remember me on my next visit to the dentist ;-) === Looking forward to hear from you.

BAGHDAD, Iraq (CNN) -- More than half-a-dozen bombs and a mortar attack ripped through Baghdad on Thursday, leaving at least 24 people dead and 67 wounded, according to an Interior Ministry source.

In the day's deadliest attack, 10 died after three car bombs detonated nearly simultaneously at a popular vegetable market in southern Baghdad's Dora district. The blast wounded 30 people, according to an Interior Ministry official.

Lettuce and bloodstained clothes littered the ground among the debris left by buildings and vehicles, according to The Associated Press. The blast's impact caused a metal roof to blow off from a loading area, leaving a van burned out, with lettuce and onions still on top of it, the AP said.

All these responses moved to adopt the document as a WG Draft, some issues have been raised for discussion, and these will be brought to the list. The present authors have therefore been asked to update the Internet Draft to taje into account corrections and formatting leading to a new revised draft that will named draft-ietf-ipdvb-ule-ext-00.txt. The new I-D will be a WG draft, intended for publication as a Standards-Track RFC (under the current ipdvb Charter). **ALL** inputs to help improve the document are therfore very welcome - including what extra should be added, what should be reworked, corrected, etc. Thanks for taking the time to read this document, Best wishes, Gorry Fairhurst (ipdvb WG Chair) From owner-ipdvb@erg.abdn.ac.uk Tue Jan 30 10:35:05 2007 Received: from [10.91.34.44] (helo=ietf-mx.ietf.org) by megatron.ietf.org with esmtp (Exim 4.43) id 1HBv0j-0004ZB-Gv for ipdvb-archive@ietf.org; Tue, 30 Jan 2007 10:35:05 -0500 Received: from [2001:630:241:204:203:baff:fe9a:8c9b] (helo=erg.abdn.ac.uk) by ietf-mx.ietf.org with esmtp (Exim 4.43) id 1HBv0b-0000Iy-Rf for ipdvb-archive@ietf.org; Tue, 30 Jan 2007 10:35:05 -0500 Received: from dee.erg.abdn.ac.uk (localhost [IPv6:::1]) by erg.abdn.ac.uk (8.13.4/8.13.4) with ESMTP id l0UFC1FK013302 for ; Tue, 30 Jan 2007 15:12:01 GMT Received: (from majordomo.lists@localhost) by dee.erg.abdn.ac.uk (8.13.4/8.12.2/Submit) id l0UFC1bv013301 for ipdvb-subscribed-users; Tue, 30 Jan 2007 15:12:01 GMT X-Authentication-Warning: dee.erg.abdn.ac.uk: majordomo.lists set sender to owner-ipdvb@erg.abdn.ac.uk using -f Received: from mail.iit.demokritos.gr (zeus.iit.demokritos.gr [143.233.226.2]) by erg.abdn.ac.uk (8.13.4/8.13.4) with ESMTP id l0UFBlOL013271 for ; Tue, 30 Jan 2007 15:11:47 GMT Received: from localhost (localhost [127.0.0.1]) by mail.iit.demokritos.gr (Postfix) with ESMTP id AFB99181F6D for ; Tue, 30 Jan 2007 17:11:52 +0200 (EET) Received: from mail.iit.demokritos.gr ([127.0.0.1]) by localhost (zeus [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 20864-09 for ; Tue, 30 Jan 2007 17:11:52 +0200 (EET) Received: from your2b9e04e703 (credo-143-233-227-003.iit.demokritos.gr [143.233.227.3]) (using TLSv1 with cipher RC4-MD5 (128/128 bits)) (Client did not present a certificate) by mail.iit.demokritos.gr (Postfix) with ESMTP id 7E62916BFBB for ; Tue, 30 Jan 2007 17:11:52 +0200 (EET) From: "Charalabos Skianis" To: Subject: NEW BOOK SERIES on Emerging Communication and Service Technologies Date: Tue, 30 Jan 2007 17:11:44 +0200 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" X-Mailer: Microsoft Office Outlook, Build 11.0.5510 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.2962 Thread-Index: Acc1a5GEnVONzqtGSBSwGVQ9xv3L3QACDeRQAALfl+AAAYxucAAtb/EwAAASVNADkPOpIAAAOJ+wAAAKVYAAAAfT4AAACkVgAAAGDNA= Message-Id: <20070130151152.7E62916BFBB@mail.iit.demokritos.gr> X-Virus-Scanned: by amavisd-new at iit.demokritos.gr X-ERG-MailScanner: Found to be clean, Found to be clean X-Spam-Status: No, No X-MIME-Autoconverted: from quoted-printable to 8bit by erg.abdn.ac.uk id l0UFC1B1013298 Sender: owner-ipdvb@erg.abdn.ac.uk Precedence: bulk Reply-To: ipdvb@erg.abdn.ac.uk X-ERG-MailScanner-From: owner-ipdvb@erg.abdn.ac.uk X-ERG-MailScanner-To: ipdvb-subscribed-users@dee.erg.abdn.ac.uk Content-Transfer-Encoding: quoted-printable X-MIME-Autoconverted: from 8bit to quoted-printable by erg.abdn.ac.uk id l0UFC1FK013302 X-Spam-Score: 0.0 (/) X-Scan-Signature: 3e15cc4fdc61d7bce84032741d11c8e5 Dear colleagues, Troubador Publsishing Ltd, having over 20 years experience on academic an= d consumer books, magazines and journals, is launching a new book series, entitled =91Emerging Communication and Service Technologies=92 (http://www.troubador.co.uk/emergingcommunication/).=20 I have identified that evolving Communication and Service Technologies present unique challenges and drive explosive changes in service offering= s, network infrastructures, and product technologies.

It would be glad if > we could get some comments on this one. I would like to be sure we understood this and the WG comes to the correct decision. In the first draft I made, there was a Type field for each PDU. The discusssions that followed made me doubt that this was the correct way: many PDUs were likely to have the same Type, it did not seem sensible to mix IPv4 with IPv6 or MPLS, VLAN traffic in the same concatenated PDU, and certainly it would make processing more complex (i.e. more error prone). So, in the draft with Bernhard we added the rule that all PDUs must have the Type within the concatenated PDU (your inputs helped motivate this). The T-bit seems a middle ground, allowing both varients at additional complexity. I'm interested to see where this can help... are there use-cases in which this would be desirable? Anybody have thoughts? > (b) We could also use the MSbit for padding purposes, > i.e. to achieve alignment (e.g. 2- or 4-byte) for the > concatenated PDUs. > The bit (P) would then control the presence of a padding control > byte right after the PDU-Length field.

This means > that in total the PDU is padded by 3 bytes (including PDU-Pad). > > If PDU-Pad=0, then we've a 1-byte of padding. How big an issue is this? The byte stream itself in which the SNDUs are carried can result in odd alignments. One of the strengths of removing the type field was that it reduced the number of possibly non-byte aligned 16-bit numbers, although the PDU-Length field (as above) still needs to be placed in a 16 bit register, and the data move that marshalls the PDU into its destination could in some architectures benefit from starting on an aligned address. So, I'm not sure what people feel about the use of padding to provide byte-alignment? If anyone has thoughts or opinions on either of these, do tell us. is a T-bit a good use? Is a form of P-bit good use? Should we reserve X (assign 0) as in the current draft?
