Let me pick-up this thread a= gain -

Do you have any published (or technical data) to support your= observations
about the S.2 link error properties?

Can I also make a plea for = anyone else with understanding of this particular
physical layer to also= come forward and comment on this topic...

Title : Problem Statement: Configuration of IP services for IPDVB Author(s) : M. Stiemerling, et al. Filename : draft-stiemerling-ipdvb-config-02.txt Pages : 16 Date : 2005-10-26 Future IPDVB networks will require a more powerful configuration management of IP addresses and related networking parameters as it is currently provided in such networks. Current discussions within the IPDVB working group have shown that the future usage scenarios and requirements for dynamic configuration management are not yet clearly defined. This memo identifies the problem space for dynamic configuration of IP networking parameters in IPDVB networks. A URL for this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-stiemerling-ipdvb-config-02.txt To remove yourself from the I-D Announcement list, send a message to i-d-announce-request@ietf.org with the word unsubscribe in the body of the message. You can also visit https://www1.ietf.org/mailman/listinfo/I-D-announce to change your subscription settings. Internet-Drafts are also available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-stiemerling-ipdvb-config-02.txt". A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-stiemerling-ipdvb-config-02.txt". 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.

X-Spam-Score: 0.0 (/) X-Scan-Signature: bb8f917bb6b8da28fc948aeffb74aa17 Content-Transfer-Encoding: 7bit Dear all, Regarding ULE, I think it is important for its viability to study the issue of its migration to DVB-H. It is unfortunately true that ULE cannot be applied to DVB-H ploatforms "as-is", because: i) DVB-H "steals" four bytes from MAC address field of MPE to use in time slicing signalling. These bytes convey the "delta-t" time i.e. the time interval until the next burst containing data from the same stream. Of course the whole process is a hack, and stems from the fact that DVB recognised that the MAC bytes are almost never used for what they were initially designed to. Possible solutions: a) using the NPA field in ULE (and destroy its initial purpose, i.e. hack ULE itself), b) adding extra bytes in DVB-H header (i.e. altering the candidate standard), c) using and standardizing an extension header ii) DVB-H uses the "MPE-FEC" structure, which is built upon MPE, and uses the table_id (first byte in MPE header) to discriminate between data bytes and FEC overhead bytes. Possible solution: directly port ULE to carry FEC frames (no action needed) and use of a new Typefield value to declare FEC data. What do you think? G.Gardikis ------- Dr. Georgios J.

That sounds reasonable and seems straight-forward to be implemented. In my opinion one more option could be to treat data+FEC as special kind of SNDU in which case another type value (data+FEC) might be appropriate. However, that would make the CRC being calculated over the whole data+FEC, and FEC recovery would start even if only FEC is corrupted. Again an extension header might be necessary to describe the type of FEC? Yet another option would be to send data and FEC in different IP packets and do the recovery on top of IP. But that changes the semantics of the current FEC mode completely. > What do you think? I see a generic problem with ULE and DVB-H related to the implicit packing of ULE, which is a little more tricky to implement following the current ULE spec where packing timeout would interfere with time slicing. > G.Gardikis Kind regards, Bernhard > ------- > Dr. Georgios J.

I will be out of the office starting 2005-11-03 and will not return until 2006-10-31.

Dear Friends and Academic and Business contacts,

I am moving on to venture my own, new business, and my Nera email address
will soon stop working. I therefore now have a new email address.

However, in order to try and loose some spam on the way there is an
intermediate address to use. Please resend you message to

skinnemoen.nera@gmail.com

and I will reply to your email and give you the correct address to use for
the future.

My GSM number will remain the same as before.

If your email is about NERA Business, please resend to sn@nera.no.

Med best regards,

As such, the original mandate to use ULE (2-way links) does not apply. So please, please, please check the ULE design assumptions. E.g. the time slicing and MPE-FEC frames may interfere with your packing and timing assumptions. Also, the DVB-H and ULE design assumptions because the intended applications - hence I feel it has no bearing on the viability of ULE whether it is every used over DVB-H. conversely, use over 2-way DVB-S links seems to be essential to prove ULE's viability. DVB operates on a process of commercial requirements -> technical requirements -> technical proposals and specifications -> technical standards and guidelines. A commercial requirement within DVB-CM demonstrating the need for something other-than-MPE would be needed for ULE to be viable over DVB-H. (Assuming, you share my opinion that without DVB and thus ETSI adoption of a DVB-H bearer technology, it has no viability in anycase). MPE-FEC was created through a design process I was not involved in. However it would be prudent to try and get an understanding of it's design selections and assumptions if you were to attempt a ULE-FEC. For academic purposes it would be interesting to merely copy the MPE-FEC approach with R-S and the same framing parameters. For the "delta-t", I came to the conclusion that (c) a header extension would be the best approach (a few years ago when I was curious about the feasibility of ULE for DVB-H - another lifetime :) I think it would be interesting to check the feasibility of ULE over DVB-H, but am not currently optimistic about it's uptake potential.

Data and FEC are transmitted separately, so that the system is backwards compatible. A FEC-ignorant receiver just decapsulates the datagram and discards the FEC bytes (which are transmitted in separate SNDUs). So, CRC is calculated over the data bytes and over the RS overhead seperately. No problem on that. But unfortunately, I forgot something: DVB-H also uses the section_number and last_section_number of the MPE header. Seems like DVB decided to revive all unused fields of MPE! Prior to calculating the FEC, a bunch of incoming IP datagrams are organized in a two-dimensional array, over each row of which the R-S is calculated. These two one-byte fields of MPE show the position which the encapsulated datagram has within this array. It is essential for proper FEC decoding. So, this issue also has to be solved for ULE (maybe with an extension header again, it just has to be incorporated in ULE). >I see a generic problem with ULE and DVB-H related to the implicit >packing of ULE, which is a little more tricky to implement following the >current ULE spec where packing timeout would interfere with time slicing. > > Indeed. Time slicing is very tricky itself, not mentioning its possible conflict with packing timeout. It has nothing to do with traditional TDM with time slots, since both burst length and inter-burst time can be altered on a per-burst basis. In order to make an efficient bandwidth management and not throw capacity away (by transmitting empty bursts), you need a rather smart and adaptive algorithm at the encapsulator. If you decide to use ULE packing simultaneously, things become even more complicated. That's an interesting research field, though.

I hvae pointed out my concerns about this possible interference as well, but was addressing more the implementation issue. Operationally also for DVB-H ULE (especially in case of IPv6, which seems to be condidate protocol and IP-multicast [video streaming] as killer app) is very well suited. ULE could even assist in cases where MPE completely fails, such as availability of NPA (MAC) addresses of transmit gateways in multi-service environments and SSM multicast. > Also, the DVB-H and ULE design assumptions because the intended > applications - hence I feel it has no bearing on the viability of ULE > whether it is every used over DVB-H. conversely, use over 2-way DVB-S > links seems to be essential to prove ULE's viability. Again, I do not get the point. ULE was never ever solely intended for 2-way links. Actually 2-way DVB links are just one possible scenario. > DVB operates on a process of commercial requirements -> technical > requirements -> technical proposals and specifications -> technical > standards and guidelines.

However, commercial requirements are driven by commercial aspects. If someone in the commercial module of DVB finds out that ULE saves money (less overhead) and adds extra functionality (more services) it is quite likely that ULE is being requested.

I think the above is simply wrong: The UNIDIRECTIONAL Lighweight Encapsulation (ULE) is just that, it works on 1-way links. True, there are cases where two-way links could use ULE (or any of the variants of MPE for the matter), but you can always use two unidirectional bearers to provide bi-directional connectivity. > So please, please, please check the ULE design assumptions.

That seems a reasonable summary of DVB's method of operation. The IETF process is different, and in this case, I'd encourage experimental implementation of things that may be useful, along with use-cases that show how you envisage the usage in real networks. The WG could then see if there is sufficient interest in developing something. Of course, an eye to how this relates to the DVB activity would certainly be of value. If you decide to look at FEC and ULE, it would also be useful to relate this to IETF work on transport packet-level FEC (FECFrame, for instance). > Gorry From owner-ipdvb@erg.abdn.ac.uk Mon Nov 14 10:31:10 2005 Received: from odin.ietf.org ([132.151.1.176] helo=ietf.org) by megatron.ietf.org with esmtp (Exim 4.32) id 1EbgIY-0006ri-IG for ipdvb-archive@megatron.ietf.org; Mon, 14 Nov 2005 10:31:10 -0500 Received: from ietf-mx.ietf.org (ietf-mx [132.151.6.1]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id KAA29363 for ; Mon, 14 Nov 2005 10:30:38 -0500 (EST) Received: from dee.erg.abdn.ac.uk ([139.133.204.82] helo=erg.abdn.ac.uk) by ietf-mx.ietf.org with esmtp (Exim 4.43) id 1EbgZb-0000Fu-MJ for ipdvb-archive@ietf.org; Mon, 14 Nov 2005 10:48:48 -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 jAEFGwIA029370 for ; Mon, 14 Nov 2005 15:16:58 GMT Received: (from majordomo.lists@localhost) by dee.erg.abdn.ac.uk (8.13.4/8.12.2/Submit) id jAEFGw9Q029369 for ipdvb-subscribed-users; Mon, 14 Nov 2005 15:16:58 GMT X-Authentication-Warning: dee.erg.abdn.ac.uk: majordomo.lists set sender to owner-ipdvb@erg.abdn.ac.uk using -f Received: from smtpout04-03.prod.mesa1.secureserver.net (smtpout04-03.prod.mesa1.secureserver.net [64.202.165.198]) by erg.abdn.ac.uk (8.13.4/8.13.4) with SMTP id jAEFGll3029347 for ; Mon, 14 Nov 2005 15:16:48 GMT Received: (qmail 9572 invoked from network); 14 Nov 2005 15:16:42 -0000 Received: from unknown (HELO gem-wbe02.mesa1.secureserver.net) (64.202.189.27) by smtpout04-03.prod.mesa1.secureserver.net with SMTP; 14 Nov 2005 15:16:42 -0000 Received: (qmail 3857 invoked by uid 99); 14 Nov 2005 15:16:41 -0000 Date: Mon, 14 Nov 2005 08:16:41 -0700 From: Marie-Jose Montpetit Subject: RE: ULE over DVB-H To: ipdvb@erg.abdn.ac.uk Message-ID: <20051114081641.ca5566c7162b3cfcb6c200079b757bd6.4a8d3b587d.wbe@email.email.secureserver.net> MIME-Version: 1.0 Content-Type: TEXT/plain; CHARSET=US-ASCII X-ERG-MailScanner: Found to be clean, Found to be clean 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-Spam-Score: 0.0 (/) X-Scan-Signature: 3971661e40967acfc35f708dd5f33760 In our ESA study of 2 years ago we did simulate ULE for 2-way but it was not the intended usage. I think it was understood that it was one-way or the return channel would use something else in general. On acceptance I think that before someone in industry (and a consortium of major players in this case because of the scope of DVB-H) really thinks ULE work better it will may be hard to push. Bandwidth savings is one selling point but how much depends as you know on traffic profiles and service scenarios. IPv6 is still not a given. Multicast maybe as IPTV needs it. We need to have someone (but who?) do a real commercial viability assessment. Also the cost of redoing firmware may kill all other benefits and should be looked at. What was RCS's feedback?

HI All,
 
Reading through some recent email = exchanges=20 has triggered in my mind the following very basic question:  =
 
What are the real benefits of ULE = compared=20 to MPE ?
 
Can someone or some people answer = this basic=20 question, in terms of:
 
* Bytes overhead = saving
* IPv6
* IP multicast
* Any operational = consideration
* Coding efficiency
* Future = uses
* Any other savings
 
Many thanks
Haitham

I think we should look in this document only generally on the requirements that ULE and its users could have, and should either produce documents describing the usage of IPsec over ULE (and what it provides / not provides), the usage of encryption on ULE level (and what it provides / not provides), and the usage of encryption below ULE, or describe in an impartial way pros and cons of the three possibilities. - In general, based on IETF tradition it is never a good idea to mix requirements / problem statements and partial solution in a single doc. E.g. we can say we need terminal authentication, but shouldn't say on which layer nor during which phase (these are questions to be answered later in a security solution design process) - The draft says repudiation is an application layer issue, however, means for non-repudiation (at least for non-repudiation of origin) can also be done on the network layer (digital signature of single packets) - Rather than saying "The ULE security solution should be compatible with functions such as NAT/NAPT, IPsec, TLS, ..." it should be "The ULE security solution should be compatible with functions such as NAT/NAPT." - The comparison of the different security approaches IPsec, L2security below ULE, L2 security as part of ULE is incomplete and misleading. E.g. all three will have no problems with NAT and PEP if only used between encapsulator and receiver and - as usual - the NAT and PEP functionality is outside this link - What means "Protection of the management system and the infrastructure from unauthorised people"? Management systems use like data the same transmission techniques, so there shouldn't be a difference for them. - The doc could say more about key management (especially for multicast key management), e.g. which type of multicast key management will be required (static, automatic), will key-revocation be needed for multicast, ... - Is network access control an issue? - The large transmission range of satellite technology is in no case an argument to consider legal issue. The whole Internet has a global coverage, so what is good for the Internet from a legal point of view, should also be good for ipdvb specifically. - It is not clear to us if the MAC / NPA protection is a big requirement, as also on other foo networks these are unprotected. The only argument here could be that they need to be protected as satellite links have a large reachability to other foo networks, so the visibility of the L2 identifiers and consequently their traceability is larger. Still I'm not sure if this is a major requirement. - It is good to just define the usage of e.g. IPsec or L2-Security with ULE and leaving out the details of how the keys are managed. This allows the WG to re-use already existing key management approaches (IKE, IKEv2, GSAKMP, etc) and the adoption of the used cryptographic methods to local legislation. - The often cited drawback of IPsec in tunnel mode (large overhead due to 2 IP headers) could be quickly reduced if e.g. ROHC within the IPsec tunnels is used. AFAIK, the MOBIKE WG is looking into this (Goals & Milestones: Jan 06 Submit Reduced Tunnel Overhead Mode for IPsec to IESG for Informational RFC). It is not yet clear if they really will meet the milestone in time and how fast implementations will pick this up, but the work of this WG could invalidate some of the arguments put forward in favour of ULE encryption.

Agenda --------- (WG Chair, Gorry Fairhurst) This was the 5th meeting of the IPDVB WG at the IETF. The meeting was chaired by Gorry Fairhurst. The proposed agenda was accepted. An additional presentation by Axel Jahn on IP over DVBS.2 had been received, which the WG Chair would present. 2. Document Status=20 ------------------ (WG Chair, Gorry Fairhurst) Active WG Drafts: draft-ietf-ipdvb-ule-06.txt (Proposed Standard) RFC Editor queue in EDIT IANA. draft-ietf-ipdvb-arch-04.txt (Informational) RFC Editor's queue in Auth48 call. draft-ietf-ipdvb-ar-01.txt Active WG draft. Protocol entries for ULE has been created in registries at: - ISO/SMPTE - ATSC - IANA Next-Header registry These registry assignments are now permanent. Other related documents Individual Drafts for consideration by WG: draft-stiemerling-ipdvb-config-01.txt draft-cruickshank-ipdvb-sec-req-00.txt draft-cruickshank-ipdvb-sec-00.txt draft-cantillo-ipdvb-s2encaps-01.txt There had been a re-charter of the WG Charter milestones, after the last IETF meeting. A new item added on ULE security requirements. The new milestones are progressing well and all completed on time. 3. Presentation on IP Address Resolution ---------------------------------------- (draft-ietf-ipdvb-ar-01.txt) Marie-Jose Montpetit Marie-Jose presented an overview of the document structure and noted that this must work in all MPEG-2 networks: address resolution should be technology agnostic. The I-D was to: Define terminology, lead to a common understanding, review implementation scenarios. Address resolution should also be considered above IP and the goal is how to make the implementation more IP friendly. The I-D is applicable to whatever MPEG-2 transmission is used (satellite, cable, handheld, ...) and presents methods to ensure AR is network-aware / technology agnostic (mobility of solutions) and speaks about integration into multiple signaling paradigms: DVB-SI and IMS/SIP; This can resolve other parameters: encapsulation method, MTU, policy/priority/QoS, security, packing threshold. The current revision -01 is now in good shape. Updates include: - Added description of use of SI. - Various things based-on discussion on the list. - Fixes to document format. She presented the intended work for I-D rev. -02: - Investigate integration into other new trends: SIPPING, ipconfig, autoconf; - Closer integration into other standards bodies; - Inputs are requested from the WG on mobility, DVB-H, IMS; - Also: cable/broadcast strategies usage, IP streaming over MPEG-2. Gorry Fairhurst: There are a lot of things that could be added. How long until the I-D is ready for a WGLC? Marie-Jose Montpetit: This is some kind of shopping list, we propose to cycle it one or two more times, and get comments from the list. The I-D should be ready by early next year. Gorry Fairhurst: The milestone is March 2007. Marie-Jose Montpetit: Seems OK. Gorry Fairhurst: I encourages people to read next draft, and offer contributions where able. 4. Presentation on IP Address Configuration ------------------------------------------- (draft-stiemerling-ipdvb-config-02) Martin Stiemerling There has been progress, the I-D has been reorganised, and is now ready for comments from the WG. Open issues include the configuration parameters, sets of configuration items, and how to reconfigure? The I-D still needs to differentiate between the configuration roles of the MPEG-2/DVB operator and IP operator. There is no current conclusion on whether new protocols are needed? Marie-Jose Montpetit: The I-D speaks about MPEG-2/DVB and IP operators. What about content provider configuration? Martin Stiemerling: That's a good question. It should enter the picture somewhere. Marie-Jose Montpetit: All these people have configuration. Martin Stiemerling: If we talk about IP-level questions, then I am not sure they are involved, if this is at the service-level, then there is configuration. Gorry Fairhurst: Does anyone have NDP experience in very flat networks - i.e. scalability to large numbers of systems? Marie-Jose Montpetit: The Secure Neighbor Discovery WG (send) has work on scaling, captured in an RFC. This is important to the AR I-D. Martin Stiemerling: I will look into this point. Gorry Fairhurst: Is the I-D heading towards an Informational RFC. Should the outcome be part of another I-D? Martin Stiemerling: There can be recommendations on DHCP, NDP, arp, etc. Gorry Fairhurst: This seems to fall within the Chartered item on Address Resolution. We may finally need to consider whether this I-D should be combined with the AR draft. For now, I am very happy to see the I-D proceed, and would like to see contributions. 5. Presentation Security Requirements ------------------------------------- (draft-cruickshank-ipdvb-sec-req-00) Sunil Iyengar A security I-D had been presented at IETF-63 (in Paris). The proposed L2 security method is based on an analysis of ULE. It had received many good comments at the previous meeting, but also some important questions from the IETF Security Area. This new I-D responds to these comments. It mainly describes threats and security requirements. The L2 security association is between an Encapsulation Gateway and the Receiver. A number of issues have been brought up on the mailing list. The authors are reading these and intend to work through them on the mailing list after the IETF meeting. The intention is to revise the document in December 2005, collect more feedback, and finally ask the WG to adopt it against the new Milestone. Martin Stiemerling: The document is about ULE security. Why is NAT in the L2 security document? Sunil Iyengar: ULE security does not impact NAT functions, but we need to ensure the security framework is compatible with NAT functions. Martin Stiemerling: On some links, there is no NAT. Gorry Fairhurst: I requested a work-item on ULE security requirements. Should it have been on IP security requirements when using DVB/MPEG? If so I may have requested the wrong name for the Milestone, we should see how the I-D develops and look at the current Milestone. Gorry Fairhurst: So, the NAT issue is more of an IPsec issue, than a ULE issue? Sunil Iyengar: Yes, just that. Martin Stiemerling: So the security requirements go beyond just ULE? Gorry Fairhurst: Yes. Specifically we were asked to talk about IPsec, bulk link encryption. Link encryption. This was requested at IETF-63. Martin Stiemerling: This needs to be explained in the title or elsewhere. Marie-Jose Montpetit: The authors appear to come from the satellite community. There are other MPEG-2 networks that could use ULE. Are there plans to extend the involved folks beyond satellite? Sunil Iyengar: Yes, it would be helpful. If you have expertise or requirements, please do contact us, we're looking for contributions. Marie-Jose Montpetit: A title change to MPEG/DVB security would help, and help encourage more contributions. Gorry Fairhurst: I'd like to see the scope as what needs to be done to make the Internet security service secure, and what needs to be done below the Internet layer to make this happen. Gorry Fairhurst: There was discussion on L2 signaling on the list (originally looking at AR). Is this topic ready to be summarised? Sunil Iyengar: Yes, I will send something to the list tomorrow, and will talk about what authentication means in this context. 6. Presentation Security Method ------------------------------- (draft-cruickshank-ipdvb-sec-00) Sunil Iyengar This was the same I-D that had been presented at IETF-63. The authors will keep this draft alive while the requirements I-D matures, and update it. There will a new version -01 at the end of January 2006. 7. DVB-S.2 Framework -------------------- (WG Chair, Gorry Fairhurst) Gorry presented one slide showing the position of the new DVB-S.2 physical-layer within the protocol stack. This was expected to become a widely deployed standard and support existing ULE, MPE, etc via a transport stream interface. There was also a direct mapping of IP packets into the physical layer, known as the Generic Stream. This was under study in DVB-GBS, and was the topic for the next few presentations. There is an opportunity here to ensure that the two modes of DVB-S.2 have a common IP interface (e.g. based on ULE). 7.1 DVB-S2 Encapsulation =AD GBS Activities ----------------------------------------- (prepared by Axel Jahn, presented by Gorry Fairhurst) Axel was responsible for S.2 IP Encapsulation work within DVB-GBS. The presentation described how DVB-GBS intends to define S.2 encapsulation requirements and evaluation criteria (see slides). The IP/S.2 group will send a copy of their document to the ipdvb mailing list. The group is asking for potential encapsulation methods. Next year, the comparison and evaluation would start. Many ipdvb WG members are already participating in this process, others are welcome via a DVB member.=20 7.2 Requirements for IP over DVB-S.2 ------------------------------------ (draft-cantillo-ipdvb-s2encaps-01) Juan Cantillo Juan presented a framework for IP encapsulation using Generic Streams. This version of the I-D has been completely rewritten, based on comments on and off the list. He presented a list of pending issues concerning the I-D. The next step is to propose this as a WG item. This is a hot topic, but does the WG scope cover DVB-S.2? Martin Stiemerling: What is the fragmentation problem? Juan Cantillo: ULE fragments SNDUs in MPEG-2, in S.2 BBframes have no defined method for flexible fragmentation. Martin Stiemerling: We already have ULE, is fragmentation out of scope? Gorry Fairhurst: I'm not sure this is the same problem, let's take questions about scope later. Josef Schmidbar: Are there any plans to utilize the different modulation options and link these to the IP QoS? Juan Cantillo: I am not aware of any work yet, most current systems also use MPEG-2 at constant rate. QoS could be added to the I-D. The authors would welcome ideas and text for this. Mark Watson: What is the relation between physical layer FEC and packet-level FEC? The physical layer is not necessarily the best place to expend effort to ensure overall reliability. Can the whole stack be optimised? Juan Cantillo: We are hopeful about driving ideas on cross-layer optimizations between L2 and L3. This topic needs to explored, and has many implications on IP. We are not yet talking about application optimisation, this is in the longer term. Gorry Fairhurst: You are bound to consider about applications/transport if you need to understand the loss/error requirements of specific flows. acket FEC, is now an important IETF Transport Area topic, with documents in AVT and RMT WGs, and a BoF this IETF (FECFrame). This WG is not the only place in the IETF to address this topic. Juan Cantillo: There are potential some tools in S.2, that we can use for example the ISI field. Gorry Fairhurst (WG Chair): The Charter defines what the WG should do. Any change needs to be discussed with our Area Director (and the IESG). Anyway, the WG should not duplicate what is done in another organisation. Axel's contribution seems to clarify things. It seems to methat the I-D is more focussed on IP and there is no overlap. This may compliment work in DVB-GBS by bringing Internet experience. How many had read draft-cantillo-ipdvb-s2encaps-01? (6 people had read the document) How many people think the WG has expertise to work on this topic? (6 people had read the document) The authors should continue to revise this I-D, and the WG should pursue this topic on the mailing list. The protocol specification is not a valid WG item: It would therefore be premature to propose any Milestone in this space within the ipdvb WG. 8. ULE Implementation Status ---------------------------- (WG Chair, Gorry Fairhurst) Gorry presented a list of known implementations. Once ULE is published as an RFC, implementors should be encouraged to bring their code up to the proposed standard. There is another new implementor working on trial open source for a ULE Gateway. No details were available yet, but we should expect an announcement in a few months, this will complement the existing open-source Receiver. He asked if there were any news from other implementors? Josef Schmidbar: University of Salzburg had contributed to the Linux ULE release (now a standard feature of the kernel), and had recently discovered a small bug. The treatment of the D-bit (destination NPA/MAC address suppressed) was wrong when D=3D0 (specified MAC/NPA address) and a multicast L2 address was used. This could lead to unexpected packet loss for IPv4/IPv6 multicast. Gorry Fairhurst: Was this implementation going to be fixed? Gorry Fairhurst: Yes, and it would be uploaded to the Linux distribution. 27 people were in the meeting room, and some also participated via jabber/audio. The session ended at 2:30pm.

One solution could be using the LLC/SNAP header (which has a Protocol Identifier field) , but according to the MPE specification, when carrying IP packets, the LLC/SNAP header must not be used. The ULE specification defines a Type field in the ULE header, which allo= ws to signal the type of PDU included in the SNDU, and for IP packets: the = IP version.

Can someone or some people answer this basic question, in terms of: * Bytes overhead saving * IPv6 * IP multicast * Any operational consideration * Coding efficiency * Future uses * Any other savings Many thanks Haitham -- Dr. Haitham S.

For unicast the MAC is w= hatever (generally the MAC address of the terminal, but it could be other= things too). However, it's a design assumption in using MPE for DVB-H that signalling = the IP version below IP packet is unnecessary. This was based on various = real world implementations (which are now in commercial devices) proving = that v4-v6 filtering is only needed at IP layer and where HW acceleration= is needed it is sufficient to go several bytes in to analyse the IP head= er. Although I'm not sure why ULE would need to signal IP version, any explan= ation would be helpful.

Small packets such as those in the bi-directional unicast signalling protocols which were used as examples to justify the chartering of IPDVB. For large packets, the justification to use ULE over MPE is academic and not commerical - it will not fly without some additional, non technical, change. I have nothing against ULE - it's rather good - but making the wrong assumptions about the commercial viability of such a change from MPE would lead to a lot of misdirection and wasted effort. We don't need to be experts of standardisation to have an elementary grasp of the TCP/SCTP, UDP/DCCP, Radius/Diameter and IPv4/IPv6 deployment issues where the domain is the public Internet - exactly IETF scope. Since DVB-xxx domain tends not to be public Internet, it seems there are more, not less, issues to trouble a MP->UL transition. IPDVB was chartered as the use cases were different from DVB. When they become the same, there's a competition and I'm not IPDVB has the level of commercial participation to make a mark or server the Internet community. Since this is the heartland of ULE, I'll stop my advice on general uptake of ULE and cause no more heartburn (i.e. I assume that the issues are clear and I don't need to make myself any less popular in IPDVB :( Cheers, Rod.

This is essential practice when writing code on multiprotocol routers to prevent misinterpreting other frames and generating forwarded junk. For those who only believe RFCs, original behaviour is described in RFC1122 section 3.2.1.1. This was updated by RFC2460, which added IPv6 to the standards. ('driver' is such an endhost term.)

Sure because we could pack a number of short packets in a single payload there was an obvious gain but only if no other cost was taken into account (for example can you wait for all those packets to arrive without killing your end to end delay and jitter statistics). MPE also can do the packing BTW as was reported on this list. And sure again for really long packets the MPE overhead becomes less an issue. But overall it was more complex than that. There are a number of packets in the middle between "short" and "long" and there are many options that can be turned on and off to improve one cost element over another. And one thing we did find is that ULE was offering more flexibility in packing options who for us usually looking above IP was an advantage. And this was not also taking into account any header compression scheme. This said I do agree that there are commercial elements we did not take into account either... /mjm > -------- Original Message -------- > Subject: Re: Fwd to ipdvb: [R=E9f. : The real benefits of ULE compared > to MPE] From Laurence Duquerroy > From: Lloyd Wood > Date: Tue, November 22, 2005 6:28 am > To: ipdvb@erg.abdn.ac.uk > > On Tue, 22 Nov 2005, Gorry Fairhurst wrote: > > > Rod.Walsh@nokia.com wrote: > > > IP version appears in the IP header (sorry for stating the obvious = :) > > > > > Yes - and although that is good to verify this in the inet driver, > > Essential, actually.

2005/11/22, Marie-Jose Montpetit <marie@mjmontpetit.com>:
Just one short comment:

a= ctually when we did a study of ULE vs. MPE with ns (the code BTW has
bee= n used by many people) and queueing the results were not as clean
cut as "short" vs. "long" packets.

Sure beca= use we could pack a number of short packets in a single payload
there wa= s an obvious gain but only if no other cost was taken into
account (for = example can you wait for all those packets to arrive
without killing your end to end delay and jitter statistics). MPE also<= br>can do the packing BTW as was reported on this list.

And sure aga= in for really long packets the MPE overhead becomes less an
issue. But o= verall it was more complex than that.

There are a number of packets in the middle between "short&quo= t; and "long"
and there are many options that can be turned on= and off to improve one
cost element over another. And one thing we did = find is that ULE was
offering more flexibility in packing options who for us usually looking=
above IP was an advantage. And this was not also taking into account an= y
header compression scheme.

This said I do agree that there are = commercial elements we did not take
into account either...
