This is my old discuss text for the record: 1) This document should not recommend the use of MPTCP for tunneling, as TCP-in-TCP tunnels are generally not recommend if that can be avoided. Please remove the following part from section 3.2 and leave IP-level tunneling as the only option: „Packet distribution can be done either at the transport level, e.g. using MPTCP …“ 2) Further the following sentences also in section 3.2 should be revised: „For example, high throughput services (e.g. video streaming) may benefit from per-packet distribution scheme, while latency sensitive applications (e.g. VoIP) are not be spread over different WAN paths.“ High throughput services only benefit from per-packet scheduling if the service requires higher throughput than one of the links can provide. Also video streaming may not be a good example here because high latency variations can lead to stalls. Therefore in general per-flow scheduling should be recommend for all traffic. It could still be beneficial to schedule flows that require low latency over the link with the lower base latency, or maybe more important lower jitter, however, often it is not known to the network what the requirements on latency are for a given flow. Therefore is should probably be recommended to schedule all traffic on the "better" link (where better can be pre-configured knowledge or measured) as long as the bandwidth of the incoming traffic is smaller than the bandwidth of the that link, and only use a second link (with per-flow scheduling) if the capacity is required. 3) This document does not really normative specify the use of the newly defined options. It only gives an examples but it does not specify normatively any actions that need to performed on receipt of these options. How does the MAG know if the LMA does not support Multipath binding? An LMA that does not implement this spec will not send back an error message. Why are there two different options? What happens if one of the options is present in the Proxy Binding Update but not the other? |

I have the same concern as the SecDir reviewer in reading the draft, the concern about leaking traffic as a result of multiple tunnels is not addressed in the security considerations section. Hilary's writeup is quite helpful https://www.ietf.org/mail-archive/web/secdir/current/msg07446.html Although the editor says this is not an issue, but I don't think it's clear in the draft. |

Thanks Sri, W -------------- Old discuss position for posterity: "Section 3.2. Traffic distribution schemes "Per-packet management: the LMA and the MAG distribute packets, belonging to a same IP flow, over more than one bindings (i.e. more than one WAN interface)." This immediately made my out-of-order-packets antenna pop up, so I read the section looking for mitigations. The very next sentence reads: "Packet distribution can be done either at the transport level, e.g. using MPTCP or at When operating at the IP packet level, different packets distribution algorithms are possible. " -- the fact that this sentence is a: malformed and b: hand-wavy did nothing to allay my concerns, so I read further: "The distribution algorithm is left to implementer but whatever the algorithm is, packets distribution likely introduces packet latency and out-of-order delivery. LMA and MAG shall thus be able to make reordering before packets delivery." - I agree with the first sentence (although it is poorly worded), but the second sentence doesn't follow from the first; "shall thus be able to" implies that the prior text somehow provides a solution, not points out a problem (the sentence is also malformed)-- I think you mean something like "The LMA and MAG thus need to be able reorder packets to their original order before delivery." This then continues with "Sequence number can be can be used for that purpose, for example using GRE with sequence number option [RFC5845]." - I think that the actual reference should be RFC2890, but regardless of this, I don't think that what you are proposing works - "The Sequence Number field is used to maintain sequence of packets **within** the GRE Tunnel." (from RFC2890, emphasis added). This means that sequence numbers are local to the tunnel, and (as I understand it) your solution involves diverse tunnels. Further, Section 2.2. Sequence Number says: "The receiver may perform a small amount of buffering in an attempt to recover the original sequence of transmitted packets. In this case, the packet may be placed in a buffer sorted by sequence number." - if you are proposing using a single sequence number space for multiple tunnels, you will end up with sequence number space gabs, and lots of buffering, etc. The section ends with: "However, more detailed considerations on reordering and IP packet distribution scheme (e.g. definition of packets distribution algorithm) are out the scope of this document." - I think that, unless the prior paragraph is significantly reworked, it should not try and suggest any mitigations. The whole idea of striping packets of a flow across (notably) different transports seems like a really bad idea to me -- is it actually needed?" |

I see the requests to remove MPTCP from the document, and the rationale seems sound. If, by some chance, any mention of MPTCP remains in the final version, please make sure it gets expanded (as an acronym) and cited. The final paragraph in section 3.2 starts with "Because latency introduced by..." -- this isn't the reason damage can arise. The problem is the *variation* in latency. Suggest something like: "Because the variation in packet latency, also known as jitter, introduced by per-packet scheduling between access networks can cause..." Section 4.1, definition of If-ATT -- suggest citing the specific section: "[RFC5213] section 8.5." Section 4.1, definition of If-Label -- the value of 0 appears to be reserved? Ideally, this would prescribe specific behavior for an LMA if they receive an If-Label of 0. Section 4.1, definition of BID -- same comment; ideally, this would specify recipient behavior if set to 0 or 255. Section 4.3 defines a new response code for LMAs that don't implement this spec. Existing, already deployed LMAs will necessarily have a different reaction to receiving these unknown options than sending this response code. This section should provide guidance for MAGs letting them know what observable behavior they should expect when sending these options to LMAs unaware of this extension at all. Additionally, _if_ such observable behavior is sufficient for the MAG to understand what is happening, I would assert that the new response code is unnecessary and should be removed. Please expand the following acronyms upon first use and in the title; see https://www.rfc-editor.org/materials/abbrev.expansion.txt for guidance. - MAG - Mobile Access Gateway (in the title) - GRE - Generic Routing Encapsulation - LMA - Local Mobility Anchor - LTE - Long-Term Evolution - MN - Mobile Node - BCE - Bonding Channel Entity |

Please send substantive comments to the ietf@ietf.org mailing lists by 2017-06-16. 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 specification defines extensions to the Proxy Mobile IPv6 protocol for allowing a mobile access gateway to register more than one proxy care-of-address with the local mobility anchor and to simultaneously establish multiple IP tunnels with the local mobility anchor. This capability allows the mobile access gateway to utilize all the available access networks for routing mobile node's IP traffic. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-dmm-mag-multihoming/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-dmm-mag-multihoming/ballot/ No IPR declarations have been submitted directly on this I-D. |

02 | Jouni Korhonen | As required by RFC 4858, this is the current template for the Document Shepherd Write-Up. Changes are expected over time. This version is dated … As required by RFC 4858, this is the current template for the Document Shepherd Write-Up. Changes are expected over time. This version is dated 24 February 2012. (1) What type of RFC is being requested (BCP, Proposed Standard, Internet Standard, Informational, Experimental, or Historic)? Why is this the proper type of RFC? Is this type of RFC indicated in the title page header? This document is Proposed Standard and it is also stated in the cover page. (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 specifies a multiple proxy Care-of Addresses extension for Proxy Mobile IPv6. The extension allows a multihomed Mobile Access Gateway to register more than one proxy care-of-address to the Local Mobility Anchor. Working Group Summary The document has been in a WG for a long time and gone through a bigger change to be independent of specific deployment architecture. The solution reached consensus in the working group. Document Quality There are commercial pre-standard implementations of the protocol. The document has been reviewed thoroughly and there is no need to have external directorate reviews. Personnel Jouni Korhonen (jouni.nospam@gmail.com) is the document shepherd. Suresh Krishnan (suresh.krishnan@ericsson.com) is the responsible AD. (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. The shepherd has read the latest revision of the document and thinks it is ready for publication. (4) Does the document Shepherd have any concerns about the depth or breadth of the reviews that have been performed? No. (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. None. (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. Positive "no IPR" acknowledgements have been received from all authors. (8) Has an IPR disclosure been filed that references this document? If so, summarize any WG discussion and conclusion regarding the IPR disclosures. No. (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? The document has WG consensus and support behind it. (10) Has anyone threatened an appeal or otherwise indicated extreme discontent? If so, please summarise 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 https://www.ietf.org/tools/idnits/ and the Internet-Drafts Checklist). Boilerplate checks are not enough; this check needs to be thorough. IDnits reports one error: ** The abstract seems to contain references ([RFC3963], [RFC4908], [RFC5213], [RFC6275]), which it shouldn't. Please replace those with straight textual mentions of the documents in question. The shepherd thinks the RFC Editor can easily expand these and remove references from the abstract when producing a new revision. The same goes for the other IDnits complaints. They will automatically be corrected once the RFC editor produces a new revision. (12) Describe how the document meets any required formal review criteria, such as the MIB Doctor, media type, and URI type reviews. No need for the MIB Doctor, media type, and URI type reviews. The document has no protocol elements that would need such reviews. (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? None. (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. (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). The document requires two new Mobility Option code points and defines one new status code value. Respective IANA registries are clearly identified and no new registries are created. (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. None. (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. Shepherd has done IDnits check. No other validations were done. |
