How's that possible? Maybe this is really a DISCUSS-DISCUSS about transitive IPR declarations, but I'm not sure because of the write-up. If its considered ok that implemeters of this will have to read and thus be aware of the IPR in 5170, then I guess I'll clear but I figure its best to ask. |

But this gives no explanation as to why FECFrame wishes to publish this document. No answer in the shepherd report was given to the question of whether there are implementations of this protocol or whether there is interest by potential implementers in this work. The only references appear to be to research in this area, not an actual requirement for interoperability. Is there any interest in actually implementing this protocol, or is this simply another academic publication without community interest? |

These are non-blocking, but please consider them seriously, and feel free to chat with me about them: Throughout: All of the "MAY" words in here seem wrong: they're describing conditions that might exist, not specifying directives for making choices (unless I'm mis-reading it). You MUST consider various things when you construct an ADU block. One of those various things may or might (but not MAY) be factor A. I think all the "MAY"s in the document should be lower case (or be replaced by "might"): - the target use-case MAY have real-time constraints - [the real-time constraints] MAY define a maximum ADU block size - a codec MAY impose other limitations on the maximum source block size - The source ADU flows MAY have real-time constraints. - Reed-Solomon codes or 2D parity check codes MAY be more appropriate. -- Section 8 -- Values of FEC Encoding IDs are subject to IANA registration. [RFC6363] defines general guidelines on IANA considerations. In particular it defines a registry called FEC Framework (FECFRAME) FEC Encoding IDs whose values are granted on an IETF Consensus basis. IANA notes that "IETF Review" is the right term and suggests changing this. I suggest just removing the paragraph; it's not necessary, and it doesn't seem to have any value at all. You can move the reference to RFC 6363 to the next paragraph, which can otherwise remain as it is. |

In RFC 6363, it describes the registration procedures as IETF Review according to RFC 5226. Although they are the same (as described in RFC 5226) you may want to change the wording in the document to match up with what RFC 6363 says. IANA understands the above to be the only requested actions. Note: The actions requested in this document will not be completed until the document has been approved for publication as an RFC. |

02 | Amy Vezza | The following Last Call announcement was sent out: From: The IESG To: IETF-Announce CC: Reply-To: ietf@ietf.org Subject: Last Call: (Simple LDPC-Staircase Forward Error Correction (FEC) … The following Last Call announcement was sent out: From: The IESG To: IETF-Announce CC: Reply-To: ietf@ietf.org Subject: Last Call: (Simple LDPC-Staircase Forward Error Correction (FEC) Scheme for FECFRAME) to Proposed Standard The IESG has received a request from the FEC Framework WG (fecframe) to consider the following document: - 'Simple LDPC-Staircase Forward Error Correction (FEC) Scheme for FECFRAME' as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2012-10-01. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document describes a fully-specified simple FEC scheme for LDPC- Staircase codes that can be used to protect media streams along the lines defined by the FECFRAME framework. These codes have many interesting properties: they are systematic codes, they perform close to ideal codes in many use-cases and they also feature very high encoding and decoding throughputs. LDPC-Staircase codes are therefore a good solution to protect a single high bitrate source flow, or to protect globally several mid-rate flows within a single FECFRAME instance. They are also a good solution whenever the processing load of a software encoder or decoder must be kept to a minimum. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-fecframe-ldpc/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-fecframe-ldpc/ballot/ No IPR declarations have been submitted directly on this I-D. |

Why is this the proper type of RFC? Is this type of RFC indicated in the title page header? RFC proposed standard to wg consensus. The title page indicates Standards Track. (2) The IESG approval announcement includes a Document Announcement Write-Up. Please provide such a Document Announcement Write-Up. Recent examples can be found in the "Action" announcements for approved documents. The approval announcement contains the following sections: Technical Summary This document describes a fully-specified simple FEC scheme for LDPC-Staircase codes that can be used to protect media streams along the lines defined by the FECFRAME framework. Working Group Summary There is consensus within the FECFrame WG to publish this document. The document has been actively discussed on the wg list and in wg meetings. There was no controversy with the progression of this document. Document Quality Are there existing implementations of the protocol? Have a significant number of vendors indicated their plan to implement the specification? Are there any reviewers that merit special mention as having done a thorough review, e.g., one that resulted in important changes or a conclusion that the document had no substantive issues? If there was a MIB Doctor, Media Type or other expert review, what was its course (briefly)? In the case of a Media Type review, on what date was the request posted? Yes: K. Matsuzono, J. Detchart, M. Cunche, V. Roca, H. Asaeda, ``Performance Analysis of a High-Performance Real-Time Application with Several AL-FEC Schemes", 35th Annual IEEE Conference on Local Computer Networks 2010 (LCN 2010), October 2010. (PDF) Who is the Document Shepherd? Who is the Responsible Area Director? Greg Shepherd is the document shepherd and Martin Stiemerling is the responsible Area Director. (3) Briefly describe the review of this document that was performed by the Document Shepherd. If this version of the document is not ready for publication, please explain why the document is being forwarded to the IESG. I read the document. The AD read the document. The WG has read the document. It has been successfully run through idnits. This version of the document is ready for publication. (4) Does the document Shepherd have any concerns about the depth or breadth of the reviews that have been performed? I have no concerns. (5) Do portions of the document need review from a particular or from broader perspective, e.g., security, operational complexity, AAA, DNS, DHCP, XML, or internationalization? If so, describe the review that took place. No. (6) Describe any specific concerns or issues that the Document Shepherd has with this document that the Responsible Area Director and/or the IESG should be aware of? For example, perhaps he or she is uncomfortable with certain parts of the document, or has concerns whether there really is a need for it. In any event, if the WG has discussed those issues and has indicated that it still wishes to advance the document, detail those concerns here. No concerns. (7) Has each author confirmed that any and all appropriate IPR disclosures required for full conformance with the provisions of BCP 78 and BCP 79 have already been filed. If not, explain why. Yes. There is no IPR. (8) Has an IPR disclosure been filed that references this document? If so, summarize any WG discussion and conclusion regarding the IPR disclosures. No IPR. (9) How solid is the WG consensus behind this document? Does it represent the strong concurrence of a few individuals, with others being silent, or does the WG as a whole understand and agree with it? There is solid WG consensus behind the document. It has undergone thorough review within the AVT and FEC communities. The document has been actively discussed on the WG mailing list and in WG meetings. (10) Has anyone threatened an appeal or otherwise indicated extreme discontent? If so, please summarize the areas of conflict in separate email messages to the Responsible Area Director. (It should be in a separate email because this questionnaire is publicly available.) No. (11) Identify any ID nits the Document Shepherd has found in this document. (See http://www.ietf.org/tools/idnits/ and the Internet-Drafts Checklist). Boilerplate checks are not enough; this check needs to be thorough. No nits. (12) Describe how the document meets any required formal review criteria, such as the MIB Doctor, media type, and URI type reviews. No required formal review. (13) Have all references within this document been identified as either normative or informative? Yes. (14) Are there normative references to documents that are not ready for advancement or are otherwise in an unclear state? If such normative references exist, what is the plan for their completion? All normative references are to completed work. (15) Are there downward normative references references (see RFC 3967)? If so, list these downward references to support the Area Director in the Last Call procedure. No. (16) Will publication of this document change the status of any existing RFCs? Are those RFCs listed on the title page header, listed in the abstract, and discussed in the introduction? If the RFCs are not listed in the Abstract and Introduction, explain why, and point to the part of the document where the relationship of this document to the other RFCs is discussed. If this information is not in the document, explain why the WG considers it unnecessary. No, publication of this document will not change the status of any existing RFCs. (17) Describe the Document Shepherd's review of the IANA considerations section, especially with regard to its consistency with the body of the document. Confirm that all protocol extensions that the document makes are associated with the appropriate reservations in IANA registries. Confirm that any referenced IANA registries have been clearly identified. Confirm that newly created IANA registries include a detailed specification of the initial contents for the registry, that allocations procedures for future registrations are defined, and a reasonable name for the new registry has been suggested (see RFC 5226). IANA considerations are clear and detailed. (18) List any new IANA registries that require Expert Review for future allocations. Provide any public guidance that the IESG would find useful in selecting the IANA Experts for these new registries. No expert review necessary. (19) Describe reviews and automated checks performed by the Document Shepherd to validate sections of the document written in a formal language, such as XML code, BNF rules, MIB definitions, etc. Not applicable |
