My personal experience is that when people migrate from IP multicast to MPLS multicast and deploy mLDP going to in-band signaling is a very natural step as it preserves semantics and mode of operation of IP Multicast while bringing all the advantages of MPLS. Complexity of BGP signaling is often taken in consideration when it is compared to mLDP in-band. I'd really like to ask people who are deploying and operating Multicast (not selling it) :) to speak up Cheers, Jeff -----Original Message----- From: IJsbrand Wijnands Date: Wednesday, September 25, 2013 3:31 PM To: Yakov Rekhter Cc: "mpls@ietf.org" , "draft-rekhter-mpls-pim-sm-over-mldp@tools.ietf.org" , "mpls-chairs@tools.ietf.org" , Lizhong Jin Subject: Re: [mpls] MPLS-RT review of draft-rekhter-mpls-pim-sm-over-mldp >Yakov, > >> I can not comment on whether it is "more natural to follow the >>mechanism=20 >> in draft-ietf-mpls-seamless-mcast". > >I think the question is, is there a need for a solution that combines >mLDP in-band signalling with BGP AD.

As per RFC 5036 Section 3.5.7.1.3, the problem of a live lock situation and solution to resolve the same is mentioned as below. Downstream LSR (operating in DOD) do not send unsolicited label mapping advertisements for a FEC till it is requested by Upstream LSR (operating in DU). I have captured the snippets from RFC below. 3.5.7.1.3 . Downstream on Demand Label Advertisement In general, the upstream LSR is responsible for requesting labelmappings when operating in Downstream on Demand mode. However, unless some rules are followed, it is possible for neighboring LSRs with different advertisement modes to get into a livelock situation where everything is functioning properly, but no labels are distributed. For example, consider two LSRs Ru and Rd where Ru is the upstream LSR and Rd is the downstream LSR for a particular FEC. In this example, Ru is using Downstream Unsolicited advertisement mode and Rd is using Downstream on Demand mode. In this case, Rd may assume that Ru will request a label mapping when it wants one and Ru may assume that Rd will advertise a label if it wants Ru to use one. If Rd and Ru operate as suggested, no labels will be distributed from Rd to Ru. This livelock situation can be avoided if the following rule is observed: an LSR operating in Downstream on Demand mode SHOULD NOT be expected to send unsolicited mapping advertisements. Therefore, if the downstream LSR is operating in Downstream on Demand mode, the upstream LSR is responsible for requesting label mappings as needed. As per RFC 5036 Section A.1.6, Recognize a new FEC, Section FEC.4 (Perform LSR Label Request procedure), if LSR is operating in =93Request Never=94 mo= de (As per RFC 3031 Section 5.1.2.1, Request never is DU and Liberal Retention mode), it need not send label request message.

Hello MPLS WG,

How
 an LSP will get formed if Upstream LSR is operating DU and liberal mode

Could you please point me to the specific text in 4.2 that talks about creating an S,G route and sending S,G, mLDP message "based on BGP Source = Active AD message". Could you also point me to the specific text in 3.2 that talks about creating Source Active AD message based on S,G, mLDP message ? > b) This machinery enables immediately setting up a source tree P2MP LSP > just because the LSR learned of the source (for a G) based on BGP, > while/after it created the *,G. > = > This is not correct, as RFC4601 section 4.2.1 clearly makes using a sour= ce > tree (aka switching over from shared tree to source tree) OPTIONAL.

That is correct.

While PIM-SM ASM over MPLS network with draft-ietf-mpls-seamless-mcast uses Leaf auto-discovery routes, several flavors of S-PMSI auto-discovery routes, and Source Active auto-discovery routes, draft-rekhter-mpls-pim-sm-over-mldp uses just Source Active auto-discovery routes. Moreover, draft-rekhter-mpls-pim-sm-over-mldp spells out that in certain deployment scenarios even Source Active auto-discovery routes would not be used. > (b) Why would one be using BGP, if the intent is to use in-band mLDP > signaling? = > = > (c ) If one really wants to use in-band mLDP signaling for ASM shared > tree, then why wouldn't one use > draft-wijnands-mpls-mldp-in-band-wildcard-encoding procedures that don't > require BGP? Let me just point out that draft-wijnands-mpls-mldp-in-band-wildcard-encod= ing itself said the following: In scenarios where it does not make sense to apply "threshold infinity" to a given ASM group, a more complex set of procedures are needed, as per [I-D.rekhter-pim-sm-over-mldp]. .... [I-D.rekhter-pim-sm-over-mldp] Rekhter, Y. and R. Aggarwal, "Carrying PIM-SM in ASM mode Trees over P2MP mLDP LSPs", draft-rekhter-pim-sm-over-mldp-04 (work in progress), August 2011. So, even draft-wijnands-mpls-mldp-in-band-wildcard-encoding acknowledges that there are scenarios where it is insufficient. Moreover, this draft suggest to use draft-rekhter-pim-sm-over-mldp, *not* draft-ietf-mpls-seamless-mcast. Yakov.

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : Carrying PIM-SM in ASM mode Trees over P2MP mLDP LSPs Author(s) : Yakov Rekhter Rahul Aggarwal Nicolai Leymann Wim Henderickx Quintin Zhao Richard Li Filename : draft-rekhter-mpls-pim-sm-over-mldp-07.txt Pages : 11 Date : 2013-10-02 Abstract: When IP multicast trees created by PIM-SM in Any Source Multicast (ASM) mode need to pass through an MPLS domain, it may be desirable to map such trees to Point-to-Multipoint Label Switched Paths. This document describes how to accomplish this in the case where such Point-to-Multipoint Label Switched Paths are established using mLDP.

Please send substantive comments to the ietf@ietf.org mailing lists by 2013-10-16. 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 MPLS-TP is based on a profile of the MPLS and PW procedures as specified in the MPLS-TE and (MS-)PW architectures developed by the IETF. The ITU-T has specified a Transport Network architecture. This document provides a thesaurus for the interpretation of MPLS-TP terminology within the context of the ITU-T Transport Network recommendations. It is important to note that MPLS-TP is applicable in a wider set of contexts than just Transport Networks. The definitions presented in this document do not provide exclusive nor complete interpretations of MPLS-TP concepts. This document simply allows the MPLS-TP terms to be applied within the Transport Network context. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-mpls-tp-rosetta-stone/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-mpls-tp-rosetta-stone/ballot/ No IPR declarations have been submitted directly on this I-D.

Subject: [mpls] Implementation poll for draft-ietf-mpls-tp-te-mib
To: "mpls@ietf.org" <mpls@ietf.org>, "mpls-chairs@tools.ietf.org" <mpls-chairs@tools.ietf.org>, draft-ietf-mpls-tp-te-mib@tools.ietf.org, "VIGOUREUX, MARTIN (MARTIN)" <martin.vigoureux@alcatel-lucent.com>


Working Group,

draft-ietf-mpls-tp-te-mib has been updated after working group
last call (version -06) and the MIB Doctors and authors are noe
working to tie up the last lose ends. Once the new version is
posted we are almost ready to send it to the IESG with a request
for publication.

In preparing the shepherd write-up we need information on existing
implementations.

This is to start a poll for implementations of draft-ietf-mpls-
tp-te-mib.

If you have an implementation please respond to the mailing-list
or directly to the wg-chairs.

/Loa
for the wg chairs

As was communicated in Ross's email it has been decided to take the four documents that adds new functionality to psc and merge them into one document. For draft-osborne-mpls-psc-updates there are two possibilities, either we can do a 6368bis or we can create a document that updates 6378, both optin are within the IETF tradition. The wg chairs believes that having draft-osborne-mpls-psc-updates will be the faster way to do this. Time is essential since we are working against a deadline (ITU-T SG15 meeting) in April 2014). All the PSC documents will be needed as references by SG15. An 6378bis could turn out to be a lengthy business since it opens up the entire document for discussion.

Title : Updates to PSC Author(s) : Eric Osborne Filename : draft-osborne-mpls-psc-updates-03.txt Pages : 8 Date : 2013-10-04 Abstract: This document contains four updates to the Protection State Coordination (PSC) logic defined in RFC6378, "MPLS Transport Profile (MPLS-TP) Linear Protection" . Two of the updates correct existing behavior. The third clears up a behavior which was not explained in the RFC, and the fourth adds rules around handling capabilities mismatches.

The final agenda will be published on Friday, October 11th. https://datatracker.ietf.org/meeting/88/agenda.txt We are still having some difficulty integrating the new agenda tool into the datatracker and as a result some portions of the meeting agenda -- beverage and snack breaks, plenaries -- are not yet showing up on the html version. This will hopefully be resolved very soon.

In a world with 100G links, the overhead associated with using an Ethernet header for protocol identification really won't hurt. Or you could use an L2TPv3 PW In addition, thanks to MPLS-TP, you no longer need to signal for PWs, you can statically configure them, or use any other manual or automated provisioning you like, such as SNMP (RFCs 5601 and 5602). Also, VPLS has also shown us that full meshes of PWs scale, there are some very large VPLS deployments out there.

I agree that using a PW is = a way of identifying the MPLS payload type. However, just for the purpose o= f using the EtherType field in the Ethernet header, it requires to establis= h a full mesh of P2P PWs between PE routers in addition to adding a 14-byte= -long fake Ethernet header to each MPLS packet. Doesn't it seem a bit heavy= -weight, in the case where the number of PE routers is huge enough that [RF= C4447] signaling is not suitable anymore for setting up the PW? > > Best regards, > Xiaohu > >> -----=D3=CA=BC=FE=D4=AD=BC=FE----- >> =B7=A2=BC=FE=C8=CB: mpls-bounces@ietf.org [mailto:mpls-bounces@ietf.org]= =B4=FA=B1=ED Andrew >> G.

If you know one or more of those areas, exercise your social network and submit nominations. We'll be very grateful! Is there someone you work with at IETF who has leadership potential and a growing track record? Please read this Nomcom call for nominations and consider nominating her or him. Or several folks! Deadline for nominations is October 18. Nominate soon to give your nominee(s) plenty time to fill in the questionnaire. If you're nominated, even if you support the present incumbent, being reviewed by Nomcom is great IETF experience. The questionnaire offers a chance to think about IETF and about your area. Whether or not your candidacy progresses this time, you'll have gained some valuable insights, and you'll have contributed greatly. This process only works because many IETFers take part; please join in. Lots more, including which positions are open, how to make a nomination (including nomination of yourself), and how to send us your feedback on the desired expertise, follows. IETFers, let's hear from you! Make nominations, accept nominations! If you have any questions about the process, feel free to get in touch with me. Best regards, Allison for the Nomcom Allison Mankin Nomcom Chair 2013-14 ----- The Info You Need for Nominating ----- The 2013-14 Nominating Committee (Nomcom) is seeking nominations from now until October 18, 2013. The open positions being considered by this year's Nomcom can be found later in this section, and also on this year's Nomcom website: https://datatracker.ietf.org/nomcom/2013/ Information about the desired expertise for positions is here: https://datatracker.ietf.org/nomcom/2013/expertise Nominations may be made by selecting the Nominate link at the top of the Nomcom 2013 home page, or by visiting the following URL: https://datatracker.ietf.org/nomcom/2013/nominate/ Note that nominations made using the web tool require an ietf.org datatracker account. You can create a datatracker ietf.org account if you don't have one already by visiting the following URL: https://datatracker.ietf.org/accounts/create/ Nominations may also be made by email to nomcom13 at ietf.org. If you nominate by email, please include the word "Nominate" in the Subject and indicate in the email who is being nominated, their email address (to confirm acceptance of the nomination), and the position for which you are making the nomination. If you use email, please use a separate email for each person you nominate, and for each position (if you are nominating one person for multiple positions). Self-nomination is welcome! No need to be shy. Nomcom 2013-14 will follow the policy for "Open Disclosure of Willing Nominees" described in RFC 5680. As stated in RFC 5680: "The list of nominees willing to be considered for positions under review in the current Nomcom cycle is not confidential". Willing nominees for each position will be listed in a publicly accessible way - anyone with a datatracker account may access the lists. In all other ways, the confidentiality requirements of RFC 3777/BCP10 remain in effect. All feedback and all Nomcom deliberations will remain confidential and will not be disclosed. In order to ensure time to collect sufficient community feedback about each of the willing nominees, nominations must be received by the Nomcom on or before October 18, 2013. Please submit your nominations as early as possible for the sake of your nominees, as we've set the questionnaire submission deadline for October 25, 2013. The list of people and posts whose terms end with the March 2014 IETF meeting, and thus the positions for which we are accepting nominations: IAOC Chris Griffiths IAB Bernard Aboba Marc Blanchet Ross Callon Eliot Lear Hannes Tschofenig IESG Barry Leiba (Applications) Brian Haberman (Internet) Benoit Claise (Operations and Management) Gonzalo Camarillo (RAI) Stewart Bryant (Routing) Sean Turner (Security) Martin Stiemerling (Transport) Please be resourceful in identifying possible candidates for these positions, as developing our talent is a very crucial requirement for the IETF. Also, please give serious consideration to accepting nominations you receive. The summaries of the desired expertise for the positions, developed by the respective bodies, are found at: https://datatracker.ietf.org/nomcom/2013/expertise/ In addition to nominations, the Nomcom seeks community input on the positions themselves.

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : mLDP In-Band Signaling with Wildcards Author(s) : IJsbrand Wijnands Eric Rosen Arkadiy Gulko Uwe Joorde Jeff Tantsura Filename : draft-wijnands-mpls-mldp-in-band-wildcard-encoding-01.txt Pages : 14 Date : 2013-10-09 Abstract: There are scenarios in which an IP multicast tree traverses an MPLS domain. In these scenarios, it can be desirable to convert the IP multicast tree "seamlessly" to an MPLS multipoint label switched path (MP-LSP) when it enters the MPLS domain, and then to convert it back to an IP multicast tree when it exists the MPLS domain. Previous documents specify procedures that allow certain kinds of IP multicast trees (either "Source-Specific Multicast" trees or "Bidirectional multicast" trees) to be attached to an MPLS multipoint label switched path (MP-LSP), either in the context of a particular VPN or in a "global" (non-VPN) context. However, the previous documents do not specify procedures for attaching IP "Any Source Multicast" trees to MP-LSPs, nor do they specify procedures "aggregating" multiple IP multicast trees onto a single MP-LSP. This document specifies the procedures to support these functions. It does so by defining "wildcard" encodings making it possible to specify, when setting up an MP-LSP, that a set of IP multicast trees or a shared IP multicast tree should be attached to that MP-LSP. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-wijnands-mpls-mldp-in-band-wildcard-= encoding There's also a htmlized version available at: http://tools.ietf.org/html/draft-wijnands-mpls-mldp-in-band-wildcard-encodi= ng-01 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=3Ddraft-wijnands-mpls-mldp-in-band-wildcar= d-encoding-01 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

Title : Use of Multipath with MPLS and MPLS-TP Author(s) : Curtis Villamizar Filename : draft-ietf-mpls-multipath-use-02.txt Pages : 13 Date : 2013-10-09 Abstract: Many MPLS implementations have supported multipath techniques and many MPLS deployments have used multipath techniques, particularly in very high bandwidth applications, such as provider IP/MPLS core networks. MPLS-TP has strongly discouraged the use of multipath techniques. Some degradation of MPLS-TP OAM performance cannot be avoided when operating over many types of multipath implementations. Using MPLS Entropy label, MPLS LSPs can be carried over multipath links while also providing a fully MPLS-TP compliant server layer for MPLS-TP LSPs. This document describes the means of supporting MPLS as a server layer for MPLS-TP. The use of MPLS-TP LSPs as a server layer for MPLS LSPs is also discussed.

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : MPLS Forwarding Compliance and Performance Requirements Author(s) : Curtis Villamizar Kireeti Kompella Shane Amante Andrew Malis Carlos Pignataro Filename : draft-ietf-mpls-forwarding-01.txt Pages : 52 Date : 2013-10-09 Abstract: This document provides guidelines for implementers regarding MPLS forwarding and a basis for evaluations of forwarding implementations. Guidelines cover many aspects of MPLS forwarding. Topics are highlighted where implementers might potentially overlook practical requirements which are unstated or under emphasized or are optional for conformance to RFCs but are often considered mandatory by providers.

Before we start the working group last call we will do an IPR poll. This mail starts that IPR poll. Are you aware of any IPR that applies to draft-ietf-mpls-multipath-use? If so, has this IPR been disclosed in compliance with IETF IPR rules (see RFCs 3979, 4879, 3669 and 5378 for more details). If you are listed as a document author or contributor please respond to this email regardless of whether or not you are aware of any relevant IPR. *The response needs to be sent to the MPLS wg mailing list.* The documents will not advance to the next stage until a response has been received from each author and contributor. If you are on the MPLS WG email list but are not listed as an author or contributor, then please explicitly respond only if you are aware of any IPR that has not yet been disclosed in conformance with IETF rules.

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : A Framework for Point-to-Multipoint MPLS in Transport Ne= tworks Author(s) : Dan Frost Stewart Bryant Matthew Bocci Lou Berger Filename : draft-ietf-mpls-tp-p2mp-framework-03.txt Pages : 12 Date : 2013-10-11 Abstract: The Multiprotocol Label Switching (MPLS) Transport Profile (MPLS-TP) is the common set of MPLS protocol functions defined to enable the construction and operation of packet transport networks. The MPLS-TP supports both point-to-point and point-to-multipoint transport paths. This document defines the elements and functions of the MPLS-TP architecture applicable specifically to supporting point-to- multipoint transport paths. This document is a product of a joint Internet Engineering Task Force (IETF) / International Telecommunication Union Telecommunication Standardization Sector (ITU-T) effort to include an MPLS Transport Profile within the IETF MPLS and PWE3 architectures to support the capabilities and functions of a packet transport network. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-mpls-tp-p2mp-framework There's also a htmlized version available at: http://tools.ietf.org/html/draft-ietf-mpls-tp-p2mp-framework-03 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=3Ddraft-ietf-mpls-tp-p2mp-framework-03 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : MPLS Forwarding Compliance and Performance Requirements Author(s) : Curtis Villamizar Kireeti Kompella Shane Amante Andrew Malis Carlos Pignataro Filename : draft-ietf-mpls-forwarding-02.txt Pages : 52 Date : 2013-10-11 Abstract: This document provides guidelines for implementers regarding MPLS forwarding and a basis for evaluations of forwarding implementations. Guidelines cover many aspects of MPLS forwarding. Topics are highlighted where implementers might otherwise overlook practical requirements which are unstated or under emphasized or are optional for conformance to RFCs but are often considered mandatory by providers. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-mpls-forwarding There's also a htmlized version available at: http://tools.ietf.org/html/draft-ietf-mpls-forwarding-02 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=3Ddraft-ietf-mpls-forwarding-02 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

I have given the authors a set of comments that are mostly editorial, this is in no way impacting the IPR situation. The authors are working to update the document and the wglc will be issued on the new version Before we start the working group last call we will do an IPR poll. This mail starts that IPR poll. Are you aware of any IPR that applies to ddraft-ietf-mpls-tp-p2mp- framework? If so, has this IPR been disclosed in compliance with IETF IPR rules (see RFCs 3979, 4879, 3669 and 5378 for more details).

Title : LDP Extensions for Hub & Spoke Multipoint Label Switched= Path Author(s) : Lizhong Jin Frederic Jounay IJsbrand Wijnands Nicolai Leymann Filename : draft-ietf-mpls-mldp-hsmp-02.txt Pages : 15 Date : 2013-10-12 Abstract: This draft introduces a hub & spoke multipoint LSP (or HSMP LSP for short), which allows traffic both from root to leaf through P2MP LSP and also leaf to root along the co-routed reverse path. That means traffic entering the HSMP LSP from application/customer at the root node travels downstream to each leaf node, exactly as if it is travelling downstream along a P2MP LSP to each leaf node. Upstream traffic entering the HSMP LSP at any leaf node travels upstream along the tree to the root, as if it is unicast to the root, and strictly follows the downstream path of the tree rather than routing protocol based unicast path to the root.

The purpose of this review is to catch and fix any issues as early in the process as possible. There are a number of concerns listed below. Some are minor editorial points, and a good number of the rest can be handled by the simple addition of text to describe things that I believe need extra words. a few of the issues are a little more significant and need direct discussion or modification of the draft. I am not requiring changes, but we do need to talk about any of the points that you don't think need to be addressed by updates to the document. Thanks for your work, Adrian --- It seems to me that the issue raised by Sri on the mailing list during WG last call was not addressed. Maybe it was not of concern to this working group because you are only interested in encapsulating MPLS. The question asked, however, seems to be very valid for the people charged with looking after UDP port allocation and the future use of UDP. It can be summarised as: What would happen if every protocol asked for a port number to encapsulate it? Why don't you ask for a single port number to indicate "there is a payload protocol" and insert a shim to identify and demux the payload? I don't have a view on this, but I don't see that the WG either discussed the issue or asked for input from the TSV area. I have asked the TSV ADs to solicit input from the TSV directorate and the Port Doctors. You should not wait for this input (which may come any time between now and the end of IESG evaluation, but you should consider the issue and be prepared to discuss with the reviewers. --- Abstract This document specifies an additional IP-based encapsulation for MPLS, referred to as MPLS-in-UDP (User Datagram Protocol), which is applicable in some circumstances. This document only describes the MPLS-in-UDP encapsulation. "Additional" to what? Why "referred to as"? Isn't that exactly what it is? The second sentence seems redundant since the first sentence say exactly that. "...applicable in some circumstances" says nothing, of course. Either don't say this, or explicitly state the circumstance. Since (see below) the applicability is very specific and there is a clear use case that is the target of your work, I strongly suggest that you call out this case in the Abstract. --- Introduction Many of the same comment apply here as I noted for the Abstract, but in addition: This document specifies an additional IP-based encapsulation for MPLS, referred to as MPLS-in-UDP (User Datagram Protocol). It also describes the applicability of this encapsulation in presence of other IP-based encapsulations for MPLS. s/presence/the presence/ This encapsulation allows for two Label Switching Routers (LSR) to be adjacent on a Label Switched Path (LSP), while separated by an IP network. This makes it sound like a new feature, but (of course) MPLS-in-IP and MPLS-in-GRE allows this as well. In order to support this encapsulation, each LSR needs to know the capability to decapsulate MPLS-in-UDP by the remote LSRs. This specification defines only the data plane encapsulation and does not concern itself with how the knowledge to use this encapsulation is conveyed. While this a fundamentally reasonable thing to say, it also makes the encapsulation entirely unusable. Since implementations already exist, perhaps you could tell us how this works. I suspect that in some environments the ability exist de facto (in other words, all devices are capable) while in other environments it is configured. You could say this and then suggest that distribution of this capability between participating nodes is for future study. An applicability statement will compare situations in which using the MPLS-in-UDP encapsulation might be advantageous over other IP- based encapsulations for MPLS. One of the key considerations in this respect is how to achieve efficient load-balance of traffic over Equal Cost Multi-Path (ECMP) and/or Link Aggregation Group (LAG). I don't understand this paragraph. Are you saying that a future document might be written? That isn't very helpful! It appears that you are trying to say "This encapsulation is better than other encapsulations" but without actually demonstrating it. Either delete this paragraph or actually do the work by adding a section to this document. --- Section 1 There is quite a lot missing from this section. I don't mind whether the information goes in the main part of Section 1 or in Section 1.2, but it needs to show up. - What environment / use case is this work targeted at? - Forward reference to the Security section and a note about the non- availability of security. This is key since the applicability of this is significantly restricted by this feature. - Brief overview of the mechanism (which is very simple, so doesn't need more than a sentence mentioning "direct encapsulation", "use of dest port" and a high-level observation about using the source port for entropy and why. --- Section 1.1 Currently, there are a number of IP-based encapsulations for MPLS. These include MPLS-in-IP, MPLS-in- GRE (Generic Routing Encapsulation) [RFC4023], and MPLS-in-L2TPv3 (Layer Two Tunneling Protocol - Version 3)[RFC4817]. In all these methods, the IP addresses can be varied to achieve load-balancing. "These include..." implies you know of others. What are they and why haven't you mentioned them? I think the statement about varying the IP addresses could be clearer. Probably by saying how this is done (since simply picking another destination address may balance the load by sending it somewhere else :-) --- Section 1.1 In terms of MPLS-based encapsulations, load-balancing is achieved with the introduction of the Entropy Label [RFC6790]. I think you need to delete the word "encapsulations". --- Section 1.2 s/ECMP paths/ECMPs/ --- Section 1.2 As noted above, the explanation in this section is very sparse and could benefit from additional material. --- Section 3 Source Port of UDP I think this description needs to describe how a source behaves when the flow does not need entropy. Furthermore, the text is not clear about the objective of "providing entropy". What type of algorithm should the source use and what must it not do? For example, the entropy value can be generated by performing hash calculation on certain fields in the customer packets (e.g., the five tuple of UDP/TCP packets). I find this to be a poor example because the source has in hand an MPLS packet with an arbitrary label stack and an unknown payload. Indeed, your Section 5 notes that the MPLS payload might not be TCP or UDP. --- Section 3 Destination Port of UDP The text about upstream/downstream label assignment is perfectly fine, but doesn't belong in the description of this field. --- Section 3 UDP Checksum I note that RFC 6935 says that using a zero UDP checksum for a UDP tunnel is appropriate when the payload protocol header includes its own protection. MPLS headers do not contain this form of protection. How do you justify the zero checksum in this case? I also don't think that proper attention has been paid to Section 5 of RFC 6936. You need to examine the requirements and describe additional behavior within your document. --- Section 4 As for other common processing procedures associated with tunneling encapsulation technologies including but not limited to Maximum Transmission Unit (MTU) and preventing fragmentation and reassembly, Time to Live (TTL) and differentiated services, the corresponding "Common Procedures" defined in [RFC4023] which are applicable for MPLS-in-IP and MPLS-in-GRE encapsulation formats SHOULD be followed. I think it is probably important to consider PMTU in the presence of ECMP (probably not necessary in the case of LAG). How does the source know the PMTU for each different value of the source port that it might apply? --- As far as I can see Section 5 is not ECN-friendly and says that when the payload protocol of the MPLS packet is not "TCP-friendly" the application generating the packets must use magic to avoid swamping the network. We will see what the TSV area congestion experts have to say, but I think we will find that the approach here is simplistic unless the network across which the UDP tunnel runs is used for no other traffic except UDP tunnels carrying MPLS packets. --- Section 6 seems to indicate a major draw-back of this scheme. You have to note that MPLS networks are able to get away with having very little security because it is very hard to inject MPLS packets into a network. But MPLS-in-(foo-in-)IP encapsulation provides a way to inject packets just like any packet can be injected into an IP network. Security (such as IPsec) provides a way to ensure that rogue packets do not have their headers stripped and their payload MPLS packets added to an LSP. You are making a clear statement that using IPsec means that there is no point in doing MPLS-in-UDP encapsulation. You need to follow up on this! The first thing to do is to enhance the applicability text in Section 1 to say where you would deploy this such that security is not an issue. The second thing is to talk about the security mechanisms that can be applied at the edges of the network to reduce the likelihood of such attacks being possible. Lastly (or probably firstly!) you need to describe the attack vector and the implications of such an attack so that the implementer/deployer is clear what the risks are. --- 10.1 RFC 4023 needs to be a normative reference since you rely on it to describe how to set TTL and avoid fragmentation.

[RFC5654] defines two terms.

IMHO and FWIW this is not correct. To the best of my understanding the two d= irections of an MPLS-TP co-routed bi-directional path share lifespan (i.e.,t= hey are set up and torn down in a single management or control plane operati= on). But they do not share fate, as can be seen from the following examples: 1. A unidirectiona fiber cut in one of the links used by a co-routed bi-dire= ctional trail will result in traffic failur in the affected direction but no= t necessarily in the reverse one 2. Consider the case when one of entries the ILM in one of the transit LSRs= is corruped. This will result in incorrect failure of a single label, but t= he rest of the labels would be handled correctly. Since co-routed bi-directi= onal trails do not require using the same label in both directions of a trai= l, the fate sharing would be broken. (Actually, in such a way it could be easily broken even if the same label is= used on each segment of the LSP in both directions...)

I must admit that I've mssed the text in 5960 to which you refer. The original definition, to the best of my understanding, is in Section 1.2.= 2. of RFC 5654 and says something else: Co-routed Bidirectional path: A path where the forward and backward directions follow the same route (links and nodes) across the network. Both directions are setup, monitored and protected as a single entity. A transport network path is typically co-routed. To me this means that if one of the directions of the co-routed bi-direction= al path fails to convey traffic, the monitoring mechanisms will report the entire bi-directional path as fail= ed. To the best of my recollection when I=3DD to become RFC 5960 has been discus= sed I've asked the authors of RFC 5960 whether the pairing between two direc= tions of a co-routed bi-directional MPLS-TP LSP in a transit LSR is limited= to OAM processing, and they (or one of them) have confirmed that this is in= deed so. I wonder whether this can be interpreted as "fate-sharing".

I fully agree that the confusion is over what "fate-sharing" means. E.g., OAM for an MPLS-TP LSP and user traffic that is carried by such an LSP= are fate-sharing by design: * Your interpretation (as I understand from your example) mainly deals with= the control/management plane aspects of an LSP. From this point of view the= forward and backward directions of a co-routed bi-directional LSP are indee= d fate-sharing. E.g., the definition in 5654 implies (from my point of view)= that the corresdponding data plane configuration is set up/torn down atomic= ally. However, if I extend/tweak your example a bit, I could say that unidirection= al MP2M LSPs set up by LDP within a given AS are fate-sharing with IP traff= ic paths set up by the IGP running in this AS - but somehow I do not feel th= at such a usage of the term "fate-sharing" would be appropriate. (If it were= . there would be no need for LSP Ping...) * My interpretation includes also the data plane aspects of an LSP. E.g., u= ser traffic in an MPLS-TP LSP (of any type) and its OAM packets are fate-sha= ring by design, because exactly the same part of the label stack is looked f= or forwarding decisions (please note that both identification of OAM packets= using GAL/GACH and prohibition of ECMP are part of this design). But two di= rections of a co-routed bi-direction LSP are not fate-sharing in this sense= IMHO - unless such an LSP is (a) monitored using some OAM mechanism and (b)= user traffic is blocked on both directions of an LSP if the monitoring mech= anism reports that one direction has failed. However, it is usually possibl= e to say which direction has really failed in the case of a uni-directional= failure: e.g., the local diagnostic of the BFD session - if used for monito= ring - would report time-out expiration at one endpoint and "peer declared s= ession down" at the other endpoint. ________________________________________ From: Bhatia, Manav (Manav) [manav.bhatia@alcatel-lucent.com] Sent: Monday, October 14, 2013 7:26 AM To: Alexander Vainshtein Cc: rtg-dir@ietf.org; draft-ietf-mpls-tp-rosetta-stone.all@tools.ietf.org; m= pls@ietf.org; rtg-ads@tools.ietf.org Subject: RE: RtgDir review: draft-ietf-mpls-tp-rosetta-stone-12.txt Sasha, I think the confusion is over what we mean by "fate sharing".

To me, if the forward path is torn down for some reason, and that results i= n the backward path being torn down as well, then they inextricably "share = the fate". If the path of the forward LSP changes because of an IGP trigger, then the = backward LSP changes too in case of co-routed bidirectional LSPs. However, = this isn't true in case of Associated bidirectional LSPs. Similarly, an IGP= change (or a network event -- link/node flap, link/node down) will always = result in both directions changing their path in case of co-routed bidirect= ional LSPs.

I fully agree with you that there is no difference in the data plane between= two directions a co-routed bi-directional LSP and two directions of an asso= ciated bi-directional LSP. The difference is mainly in management/control pl= ane, in the OAM etc. This is exactly why I find the term "fate-sharing" inappropriate when it is= applied to forward and backward directions of a co-routed bi-directional LS= P because to me fate-staring refers to first of all to the data plane behavi= or.

OAM, in large part, is in = data plane and how co-routed and associated bidirectional LSP being referen= ces in OAM is different in the data plane, not only in control and/or manag= ement planes.

I do not think that there is any contradiction between the two statements in= question: 1. From the data plane point of view, when an OAM packet is trapped by a tra= nsit LSR due to TTL expiration (there is no other way to do that), it is ide= ntified as such based on the GAL/GACH in its label stack and passed to the "= OAM engine" which is NOT part of the data plane. 2. The difference between co-routed and associated bidirectional LSPs only c= omes into play if/when the "OAM engine", as part of its handling of the spec= ific trapped packet, decides to send a response back to the its originator: (a) In the case of an associated bi-directional LSP it may be unable to do s= o in MPLS-TP (in IP/MPLS the response could be sent as an unlabeled packet) - In the case of a co-routed bi-directional LSP it can always send a respons= e to the head-end LER because it understands the pairing between the forward= and backward directions of this LSP (and it is the only entity that underst= ands that). This pairing effectively means that the outgoing label for the b= ackward direction of the co-routed bi-directional LSP can be found by the OA= M engine if it knows the incoming label (and its context) of the trapped OAM= packet - If (as in the case of segment OAM) the response should be trapped by an up= stream transit LSR and not by the head-end, it needs, the OAM engine, in add= ition to forming an appropriate label stack, must set the TTL to the right v= alue - this is what http://tools.ietf.org/html/draft-ietf-mpls-lsp-ping-ttl-= tlv-05 is about. Hopefully these notes clarify my understanding of the situation. IMHO and FW= IW they comply with the general claim of shared data plane between IP/MPLS a= nd MPLS-TP.

I believe that Eric Gray explained = that that was not interpretation and intention of RFC 5960 to see co-routed= bi-directional p2p LSP not as single unified object but as two federated o= bjects. I recall that intention was to have case of accidental co-routednes= s in associated p2p LSP. In other words, associated bi-directional was not = meant to happen to be co-routed. Well, that is my recollection of talking w= ith Eric and hope it's accurate one.

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : LDP Extensions for Multi Topology Routing Author(s) : Quintin Zhao Luyuan Fang Chao Zhou Lianyuan Li Kamran Raza Filename : draft-ietf-mpls-ldp-multi-topology-09.txt Pages : 20 Date : 2013-10-14 Abstract: Multi-Topology (MT) routing is supported in IP networks with the use of MT aware IGPs. In order to provide MT routing within Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) networks new extensions are required. This document describes the LDP protocol extensions required to support MT routing in an MPLS environment.

We should like to draw the attention to the expectation that IPRs need to be disclosed in a timely fashion after your name appears on on a document, we are talking days or weeks, rather than months; and certainly not years - we have not seen any comments on the list, we are therefore now also asking if there is support to progress the draft. /Loa On 2013-09-26 13:37, Loa Andersson wrote: >

At the very least, some terms should be given. IPR #853 was intended to obsolete IPR #686.

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : A Framework for Point-to-Multipoint MPLS in Transport Ne= tworks Author(s) : Dan Frost Stewart Bryant Matthew Bocci Lou Berger Filename : draft-ietf-mpls-tp-p2mp-framework-04.txt Pages : 11 Date : 2013-10-16 Abstract: The Multiprotocol Label Switching Transport Profile is the common set of MPLS protocol functions defined to enable the construction and operation of packet transport networks. The MPLS-TP supports both point-to-point and point-to-multipoint transport paths. This document defines the elements and functions of the MPLS-TP architecture applicable specifically to supporting point-to- multipoint transport paths.

Title : Performance-based Path Selection for Explicitly Routed L= SPs using TE Metric Extensions Author(s) : Alia Atlas John Drake Spencer Giacalone Dave Ward Stefano Previdi Clarence Filsfils Filename : draft-ietf-mpls-te-express-path-00.txt Pages : 10 Date : 2013-10-16 Abstract: In certain networks, it is critical to consider network performance criteria when selecting the path for an explicitly routed RSVP-TE LSP. Such performance criteria can include latency, jitter, and loss or other indications such as the conformance to link performance objectives and non-RSVP TE traffic load. This specification uses network performance data, such as is advertised via the OSPF and ISIS TE metric extensions (defined outside the scope of this document) to perform such path selections.

Title : LDP Extensions for Hub & Spoke Multipoint Label Switched= Path Author(s) : Lizhong Jin Frederic Jounay IJsbrand Wijnands Nicolai Leymann Filename : draft-ietf-mpls-mldp-hsmp-03.txt Pages : 15 Date : 2013-10-16 Abstract: This draft introduces a hub & spoke multipoint LSP (or HSMP LSP for short), which allows traffic both from root to leaf through P2MP LSP and also leaf to root along the co-routed reverse path. That means traffic entering the HSMP LSP from application/customer at the root node travels downstream to each leaf node, exactly as if it is travelling downstream along a P2MP LSP to each leaf node. Upstream traffic entering the HSMP LSP at any leaf node travels upstream along the tree to the root, as if it is unicast to the root, and strictly follows the downstream path of the tree rather than routing protocol based unicast path to the root.

OK, I get it. I suppose if was "if appropriate" that I stumbled on. On the other hand, you seem to believe that it is possible to know the payload of the MPLS flow at the time of encapsulation into UDP. I am very worried by this claim because: - you don't want to sniff every packet, nor do you want to vary whether zero checksum is used per packet - it is not possible to know for certain what the payload of every MPLS packet on an LSP will be just by looking at a few packets - while LSP end points may know the payload, it is unlikely that LSP mid-points will know - you may have multiple LSPs carried in one UDP-source-port tunnel So it seems to me that with MPLS as the transported protocol (which is the only intention of this document) using a zero checksum in UDP for IPv6 would never be appropriate because MPLS does not include its own CRC or other mechanism, and because you cannot know whether the payload of MPLS is using a CRC. If I am correct and it is never appropriate, it would be better to say that "using zero checksum is NOT RECOMMENDED because of..." and then point to the text you quoted. if I am incorrect then please discuss with me further. > > Section 4 > > > > As for other common processing procedures associated with tunneling > > encapsulation technologies including but not limited to Maximum > > Transmission Unit (MTU) and preventing fragmentation and reassembly, > > Time to Live (TTL) and differentiated services, the corresponding > > "Common Procedures" defined in [RFC4023] which are applicable for > > MPLS-in-IP and MPLS-in-GRE encapsulation formats SHOULD be followed. > > > > I think it is probably important to consider PMTU in the presence of > > ECMP (probably not necessary in the case of LAG).

OK. I also wonder whether you looked at DTLS. Thanks for all the work.

I only have one concern that needs to be thought about... Your new registry "LDP Multi-Topology (MT) ID Name Space" under "LDP = Parameter" namespace will be confusing to IANA I think. The four ranges = that are marked as "Reserved" for different purposes will cause IANA to = ask you what the rules are for allocation from those ranges. You need to = work out what your answer is. I am going to start the IETF last call, and I expect the question will = come up during that time.

Please send substantive comments to the ietf@ietf.org mailing lists by 2013-11-06 (this is a 3 week last call to allow extra time as people are preparing for IETF-88). 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 Multi-Topology (MT) routing is supported in IP networks with the use of MT aware IGPs. In order to provide MT routing within Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) networks new extensions are required. This document describes the LDP protocol extensions required to support MT routing in an MPLS environment.

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : Return Path Specified LSP Ping Author(s) : Mach(Guoyi) Chen Wei Cao So Ning Frederic Jounay Simon Delord Filename : draft-ietf-mpls-return-path-specified-lsp-ping-14.txt Pages : 19 Date : 2013-10-16 Abstract: This document defines extensions to the data-plane failure-detection protocol for Multiprotocol Label Switching (MPLS) Label Switched Paths (LSPs) known as "LSP Ping". These extensions allow selection of the LSP to use for the echo reply return path. Enforcing a specific return path can be used to verify bidirectional connectivity and also increase LSP ping robustness.

Seamless MPLS architectures have to be promoted = as they enable single and uniform MPLS technology, simplified service archi= tecture, simplified transport architecture, fewer adherences between transp= ort and service, simplified provisioning (limited to the edge of the networ= k), better and easier resiliency.

We should like to draw the attention to the expectation that IPRs need to be disclosed in a timely fashion after your name appears on on a document, we are talking days or weeks, rather than months; and certainly not years - we have not seen any comments on the list, we are therefore now also asking if there is support to progress the draft. /Loa On 2013-09-26 13:37, Loa Andersson wrote: > Working Group, > > this is to start a two week+ working group last call on > draft-ietf-mpls-seamless-mpls-05. > > Please send your comment to working group mailing lists (mpls@ietf.org). > > We did an IPR poll on this document prior to starting the wglc. > All the authors responded to the IPR poll that they are not aware of > any IPR's relating to this document other than the one already > disclosed. > > There are no IPRs disclosed directly against this document, disclosure > #1920 was disclosed against an earlier individual version of the > document. > > It has also been pointed out that one of the components in the Seamless > MPLS architecture is derived from RFC 5283 and that IPR disclosures > # 686 and # 853 are applicable. > > The working group last call will end Friday October 11, 2913. > > /Loa --=20 Loa Andersson email: loa@mail01.huawei.com Senior MPLS Expert loa@pi.nu Huawei Technologies (consultant) phone: +46 739 81 21 64 ___________________________________________________________________________= ______________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confiden= tielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.

Thank you for your review. I will address all your comments in the next spin of the draft. I only want to bring some clarification to your proposal: > o) In 3.7, it would be useful to mention that an important > property of co-routed bidirectional path is that the forward > and backward directions share fate. > Similarly, in 3.1, we should mention that the forward and > backward directions don't share fate. Fate-sharing is NOT a requirement for co-routed bi-directional paths. It is only a secondary effect. E.g. in a cable only one of the fibers can fail/break, same for internal ports in routers, as well as forwarding. The main requirements for co-routed bidirectional paths are: == follow exactly the same path i.e. physical sections, and nodes in both directions == the MEPS at the end-points can communicate directly via the RI (remote interface) NOT via the management plane == during a protection switch both directions are switched (at the same time) from working entity to protection entity. == both are managed as a single entity The only fate-sharing requirement in ITU-T is for OAM packets and data packets transported between the same endpoints See the first paragraph in clauses 6.4 and 7.1 of G.8113.1 and G.8113.2. To resolve your point I can add text to 3.7 that both directions are managed and operated as a single entity; and in 3.1 that they need not be a single management and operational entity. -- ***************************************************************** 请记ä½ï¼Œä½ æ˜¯ç‹¬ä¸€æ— äºŒçš„，就åƒå…¶ä»–æ¯ä¸€ä¸ªäººä¸€æ · From adrian@olddog.co.uk Thu Oct 17 06:18:38 2013 Return-Path: X-Original-To: mpls@ietfa.amsl.com Delivered-To: mpls@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 6545911E81B5 for ; Thu, 17 Oct 2013 06:18:27 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -2.56 X-Spam-Level: X-Spam-Status: No, score=-2.56 tagged_above=-999 required=5 tests=[AWL=0.039, BAYES_00=-2.599] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id RU1ekR5stYZg for ; Thu, 17 Oct 2013 06:18:22 -0700 (PDT) Received: from asmtp3.iomartmail.com (asmtp3.iomartmail.com [62.128.201.159]) by ietfa.amsl.com (Postfix) with ESMTP id 643F911E818F for ; Thu, 17 Oct 2013 06:18:22 -0700 (PDT) Received: from asmtp3.iomartmail.com (localhost.localdomain [127.0.0.1]) by asmtp3.iomartmail.com (8.13.8/8.13.8) with ESMTP id r9HDIKYE031089; Thu, 17 Oct 2013 14:18:20 +0100 Received: from 950129200 (dsl-sp-81-140-15-32.in-addr.broadbandscope.com [81.140.15.32]) (authenticated bits=0) by asmtp3.iomartmail.com (8.13.8/8.13.8) with ESMTP id r9HDIJCq031079 (version=TLSv1/SSLv3 cipher=AES128-SHA bits=128 verify=NO); Thu, 17 Oct 2013 14:18:20 +0100 From: "Adrian Farrel" To: Date: Thu, 17 Oct 2013 14:18:18 +0100 Message-ID: <02fe01cecb3b$59333440$0b999cc0$@olddog.co.uk> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit X-Mailer: Microsoft Outlook 14.0 Thread-Index: Ac7LO08u/cU1gZSjRe6Id4NFyYN+9A== Content-Language: en-gb Cc: mpls@ietf.org Subject: [mpls] AD review of draft-ietf-mpls-ldp-ip-pw-capability X-BeenThere: mpls@ietf.org X-Mailman-Version: 2.1.12 Precedence: list Reply-To: adrian@olddog.co.uk List-Id: Multi-Protocol Label Switching WG List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 17 Oct 2013 13:18:39 -0000 Hello authors of draft-ietf-mpls-ldp-ip-pw-capability, I have done my usual AD review of your draft having received the publication request. The purpose of my review is to remove any issues that I can find before the document reaches IETF last call and IESG evaluation. Technically, this is a fine piece of work, but I'm afraid I have a few of editorial issues. I hope they will be quick for you to fix so we can move ahead with the IETF last call. Please feel free to discuss/reject any of my requests. Thanks for the work, Adrian === IPoMPLS is not a common term. Fortunately you do define it quite early in the document, but not until after you have used it a couple of times. Could you please at least expand the acronym in the Abstract and Introduction, and maybe give a forward pointer to the definition from the Introduction. But be really careful! The term "IP Label Switching" seems to be hardly used anywhere (says Google) except: - in this I-D - in IOS to mean "hop-by-hop label switching" (about which I am also none the wiser :-) - in old material as a synonym for MPLS. So your definition of IPoMPLS in Section 2 doesn't actually tell us what it is. --- You need to take some care with acronyms on first use. You can check at http://www.rfc-editor.org/rfc-style-guide/abbrev.expansion.txt to see which are well known and don't need to be expanded. I see P2P PW LSR P2MP mLDP FEC L2VPN PE --- Are you sure you don't want IANA to manage a registry for State: Defines the type of application state (to be controlled). The value of this field is defined as follows: 1: IPv4 Label switching 2: IPv6 Label switching 3: P2P PW FEC128 signaling 4: P2P PW FEC129 signaling 0, 5-15: Reserved. What does "Reserved" mean? --- It seems (to me) odd that you require four SEC elements to disallow all four listed states. I would have thought bit flags would be more efficient with 1 disallows and 0 allows. But since this is a case of "I would not have done it this way", you do not need to make this change on my account provided the WG is OK with what you have here.

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : Definition of Time-to-Live TLV for LSP-Ping Mechanisms Author(s) : Sami Boutros Siva Sivabalan George Swallow Shaleen Saxena Vishwas Manral Sam Aldrin Filename : draft-ietf-mpls-lsp-ping-ttl-tlv-06.txt Pages : 8 Date : 2013-10-17 Abstract: LSP-Ping is a widely deployed Operation, Administration, and Maintenance (OAM) mechanism in MPLS networks. However, in the present form, this mechanism is inadequate to verify connectivity of a segment of a Multi-Segment PseudoWire (MS-PW) from any node on the path of the MS-PW. This document defines a TLV to address this shortcoming.

Halpern Review Date: 18-October-2013 IETF LC End Date: 6-November-2013 IESG Telechat date: N/A Summary: This document is nearly ready for publication as a Proposed Standard RFC. I believe there is one major issue that is easily addressed. Major issues: I may have simply missed this reviewing the document, but as far as I can tell there is no specification of the relationship between the MT-IDs in this document and the MT-IDs used elsewhere. Yes, I can take a guess at the intent. But is it stated somewhere that these are the same IDs negotiated in the relevant IGP? Or is there some other intent? Minor issues: Nits/editorial comments: I find it odd that the MT-ID follows the IP prefix in the various formats. Yes, the computer can parse both. But since we tend to think in Network byte order, I expect more significant information (MT-ID) to occur before less significant information (IP prefix within topology.)

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : A Thesaurus for the Terminology used in Multiprotocol La= bel Switching Transport Profile (MPLS-TP) drafts/RFCs and ITU-T's Transport= Network Recommendations. Author(s) : Huub van Helvoort Loa Andersson Nurit Sprecher Filename : draft-ietf-mpls-tp-rosetta-stone-13.txt Pages : 21 Date : 2013-10-20 Abstract: MPLS Transport Profile (MPLS-TP) is based on a profile of the MPLS and Pseudowire (PW) procedures as specified in the MPLS-TE, PW and Multi-Segment Pseudowire (MS-PW) architectures developed by the Internet Engineering Task Force (IETF). The International Telecommunications Union Telecommunications Standardization Sector (ITU-T) has specified a Transport Network architecture. This document provides a thesaurus for the interpretation of MPLS-TP terminology within the context of the ITU-T Transport Network Recommendations. It is important to note that MPLS-TP is applicable in a wider set of contexts than just Transport Networks. The definitions presented in this document do not provide exclusive nor complete interpretations of MPLS-TP concepts. This document simply allows the MPLS-TP terms to be applied within the Transport Network context.

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : Temporal and hitless path segment monitoring Author(s) : Alessandro D'Alessandro Manuel Paul Satoshi Ueno Yoshinori Koike Filename : draft-ietf-mpls-tp-temporal-hitless-psm-04.txt Pages : 17 Date : 2013-10-21 Abstract: The MPLS transport profile (MPLS-TP) is being standardized to enable carrier-grade packet transport and complement converged packet network deployments. Among the most attractive features of MPLS-TP are OAM functions, which enable network operators or service providers to provide various maintenance characteristics, such as fault location, survivability, performance monitoring, and preliminary or in-service measurements. One of the most important mechanisms which is common for transport network operation is fault location. A segment monitoring function of a transport path is effective in terms of extension of the maintenance work and indispensable particularly when the OAM function is effective only between end points. However, the current approach defined for MPLS-TP for the segment monitoring (SPME) has some fatal drawbacks. This document elaborates on the problem statement for the Sub-path Maintenance Elements (SPMEs) which provides monitoring of a portion of a set of transport paths (LSPs or MS-PWs). Based on the problems, this document specifies new requirements to consider a new improved mechanism of hitless transport path segment monitoring. This document is a product of a joint Internet Engineering Task Force (IETF) / International Telecommunications Union Telecommunications Standardization Sector (ITU-T) effort to include an MPLS Transport Profile within the IETF MPLS and PWE3 architectures to support the capabilities and functionalities of a packet transport network.

This draft is a work item of the Multiprotocol Label Switching Working Gro= up of the IETF. Title : Updates to PSC Author(s) : Eric Osborne Filename : draft-ietf-mpls-psc-updates-00.txt Pages : 8 Date : 2013-10-21 Abstract: This document contains four updates to the Protection State Coordination (PSC) logic defined in RFC6378, "MPLS Transport Profile (MPLS-TP) Linear Protection" . Two of the updates correct existing behavior. The third clears up a behavior which was not explained in the RFC, and the fourth adds rules around handling capabilities mismatches.

As described in section 1.3, in the ring topology, we have to consider the drop-and-continue node case. In this case, the drop-and-continue node will become an intermediate point. So, can we configure a MEP on an intermediate node(= drop-and-continue node)? As described in section 3.3 of RFC 6371, a MEP terminates all the OAM packets it receives from the MEG, may discards silently if addressing information in the OAM payload is different with termination node. It means that the intermediate node must NOT be configured as a MEP when per-node OAM configuration is used, because downstream nodes can't receive the OAM packets from root node. On the other hand, if the intermediate node can't be configured as a MEP, the path protection may not be able to work at this point. I think this is a serious problem.

Considering that the two drafts are addressing the same problem, and that this work is still premature we have decided to not entertain either of these drafts at this meeting. We advise the authors to seriously discuss merging the drafts and bring back that merged draft to the meeting in London.

Before we start the poll for adoption we will do an IPR poll. This mail starts that IPR poll. Are you aware of any IPR that applies to draft-wijnands-mpls-mldp- in-band-wildcard-encoding? If so, has this IPR been disclosed in compliance with IETF IPR rules (see RFCs 3979, 4879, 3669 and 5378 for more details).

If you are on the MPLS WG email list but are not listed as an author or contributor, then please explicitly respond only if you are aware of any IPR that has not yet been disclosed in conformance with IETF rules.

(draft-ietf-mpls-tp-rosetta-stone-13.txt) as Informational RFC This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Adrian Farrel and Stewart Bryant. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mpls-tp-rosetta-stone/ Technical Summary MPLS Transport Profile (MPLS-TP) is based on a profile of the MPLS and Pseudowire (PW) procedures as specified in the MPLS-TE, PW and Multi-Segment Pseudowire (MS-PW) architectures developed by the Internet Engineering Task Force (IETF). The International Telecommunications Union Telecommunications Standardization Sector (ITU-T) has specified a Transport Network architecture. This document provides a thesaurus for the interpretation of MPLS-TP terminology within the context of the ITU-T Transport Network Recommendations. It is important to note that MPLS-TP is applicable in a wider set of contexts than just Transport Networks. The definitions presented in this document do not provide exclusive nor complete interpretations of MPLS-TP concepts. This document simply allows the MPLS-TP terms to be applied within the Transport Network context. Working Group Summary There was broad support and strong consensus for this document, which is a valuable aid to understand the MPLS-TP work for people from both MPLS/IETF and ITU-T backgrounds. Document Quality This document has received wide review both in the IETF MPLS WG and also in the ITU-T. A number of small nits were found and fixed during IETF last call.

I do not think adding the proposed text is the best fix. Saying = "circumstances where IP-based encapsulation for MPLS is required and = fine-grained load-balancing of IP tunneled MPLS packets is required as = well" implies potentially that existing IP-based encapsulation for MPLS = are not appropriate for fine-grained load-balancing of IP tunneled MPLS = packets, and that's not necessarily the case, since fields in other = encapsulations can be used (and are used) for that (e.g., GRE Key, = L2TPv3 Session ID). Also, this proposal contradicts your (Adrian's) point below about the = inability to know what's encapsulated in MPLS (the proposed text says = "of IP tunneled MPLS packets").

A further point that does not imply you are incorrect, but I will note = that other MPLS-in-IP encapsulations do not have a checksum in the = transport, and perhaps that's what needs to be added to the document.

RFC 7032 Title: LDP Downstream-on-Demand in Seamless MPLS Author: T. Beckhaus, Ed., B. Decraene, K. Tiruveedhula, M. Konstantynowicz, Ed., L. Martini Status: Standards Track Stream: IETF Date: October 2013 Mailbox: thomas.beckhaus@telekom.de, bruno.decraene@orange.com, kishoret@juniper.net, maciek@cisco.com, lmartini@cisco.com Pages: 35 Characters: 75588 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-mpls-ldp-dod-09.txt URL: http://www.rfc-editor.org/rfc/rfc7032.txt Seamless MPLS design enables a single IP/MPLS network to scale over core, metro, and access parts of a large packet network infrastructure using standardized IP/MPLS protocols. One of the key goals of Seamless MPLS is to meet requirements specific to access networks including high number of devices, device position in network topology, and compute and memory constraints that limit the amount of state access devices can hold. This can be achieved with LDP Downstream-on-Demand (DoD) label advertisement. This document describes LDP DoD use cases and lists required LDP DoD procedures in the context of Seamless MPLS design. In addition, a new optional TLV type in the LDP Label Request message is defined for fast-up convergence. This document is a product of the Multiprotocol Label Switching Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements. Please refer to the current edition of the Internet Official Protocol Standards (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. This announcement is sent to the IETF-Announce and rfc-dist lists.
