This draft is a work item of the Multiprotocol Label Switching WG of the IETF. Title : A Simple Control Protocol for MPLS SFLs Authors : Stewart Bryant George Swallow Siva Sivabalan Filename : draft-bryant-mpls-sfl-control-05.txt Pages : 12 Date : 2020-01-02 Abstract: In draft-ietf-mpls-sfl-framework the concept of MPLS synonymous flow labels (SFL) was introduced. This document describes a control protocol that runs over an associated control header to request, withdrawn and extend the lifetime of such labels.

I have added a line to the Introduction.

I generally work on the assumption that the purpose of the Abstract is to h= elp the potential reader decide if they want to read the document (or more = likely to help a search engine match the document against a query) and I am= unconvinced as to value of the qualification text in deciding whether to r= ead the rest of the document.

The earlier references are in text that I included as a figure to force the= layout style I wanted, and the markdown compiler ignores references in fig= ures. The compiling process excluded unused references so they have to be f= orced. I have changed the text to

RFC Editor please remove this note which is used to force the following ref= erences to appear {{RFC3032}} {{RFC5036}}

The framework is informational and so the reference would become a down-ref= . I will leave it to the chairs and ADs on how they want to proceed with th= is. It is not unusual for a framework to be required reading and yet inform= ational.

Stewart,

Looking at the diff from the p= revious version, I just noticed=C2=A0a typo that I missed earlier. In the f= irst paragraph of the introduction, "withdrawn" should be "w= ithdraw". I also see that you added an Oxford comma, which is fine by = me! :-)

I have added a line to the Introduction.

I generally work on the assumption that the purpose of the Abstract is to h= elp the potential reader decide if they want to read the document (or more = likely to help a search engine match the document against a query) and I am= unconvinced as to value of the qualification text in deciding whether to r= ead the rest of the document.

The earlier references are in text that I included as a figure to force the= layout style I wanted, and the markdown compiler ignores references in fig= ures. The compiling process excluded unused references so they have to be f= orced. I have changed the text to

RFC Editor please remove this note which is used to force the following ref= erences to appear {{RFC3032}} {{RFC5036}}

The framework is informational and so the reference would become a down-ref= . I will leave it to the chairs and ADs on how they want to proceed with th= is. It is not unusual for a framework to be required reading and yet inform= ational.

George and I discussed this and concluded that the design was satisfactory.=

I certainly indicated this to the chairs but I cannot remember if I posted = that to the list. If any reader of this note (which will go to the MPLS lis= t) has any technical concerns WRT this point, please raise them and we will= work with you to address the issue.

I have added a line to the Introduction.

I generally work on the assumption that the purpose of the Abstract is = to help the potential reader decide if they want to read the document = (or more likely to help a search engine match the document against a = query) and I am unconvinced as to value of the qualification text in = deciding whether to read the rest of the document.

The earlier references are in text that I included as a figure to force = the layout style I wanted, and the markdown compiler ignores references = in figures. The compiling process excluded unused references so they = have to be forced. I have changed the text to

RFC Editor please remove this note which is used to force the following = references to appear {{RFC3032}} {{RFC5036}}

George and I discussed this and concluded that the design was = satisfactory.

I certainly indicated this to the chairs but I cannot remember if I = posted that to the list. If any reader of this note (which will go to = the MPLS list) has any technical concerns WRT this point, please raise = them and we will work with you to address the issue.

New version (05) has been uploaded.

This is to initiate a "two week" working group last call on
draft-ietf-mpls-base-yang.

Mote: We are allowing for the holiday season and intend to close the
wglc on Friday January 10, 2020.

Please send your comments to the mpls wg mailing list (mpls@ietf.org).

There are no IPR disclosures against draft-ietf-mpls-rmr.

Both the authors and the contributors have stated on the working group
mailing list that they are unaware of any non-disclosed IPRs that
relates to this document.

This working group last call ends Friday January 10, 2020.

The use of "first bit" and "next bits" could be confusing since it may vary by context, e.g. order on the wire and descriptive text. I think it would be better to use LSB and MSB. BTW - I quite like the figure, if for no other reason that it give a name for the R-bit. To the authors: Query/Response indicator is fine in this context, but is it possible that it might be confused with other Query/Response indicators? Do we want to talk about "SFL Query/Response indicator" as the general term? /Loa > > 5. section 3.1 SFL Control Message > > Regarding the 'Control Code', do we allocate specific value for the > query/response actions?

The Security Considerations section says "It is assumed that this protocol is run in a well managed MPLS network with strict access controls preventing unwanted parties from generating MPLS OAM packets."

We need to = confirm 1) the allocation is intended to be 26+6; 2) add something to = the TLV explanation, for example: The choice of the 26 bit size is inherited from RFC 6374 and needs to be = the same. I have added in the (6-bits) because it is unusual, but it is obvious = from the figure and we do not specify the size of any of the other = fields. The use of 6 bits was a compromise. Strictly the protocol would work = without it, but at the cost of extra messages and extra state. Allowing = the use of a 6-bit batch identifier is convenient in that it reuses the = DS field in the RFC6374 structure.

I have tidied the text a little to mirror the RFC 6374 layout. I really do not think it is necessary to say 4-bits. It now looks like this - not sure it it is back to where it started: Flags: The format of the Flags field is shown below. +-+-+-+-+ |R|0|0|0| +-+-+-+-+ SFL Control Message Flags. The meanings of the flag bits are: R: Query/Response indicator. Set to 0 for a Query and set to 1 for a Response. 0: Set to zero by the Sender and ignored by the Receiver. Note that this then style matches the text that follows. > =20 > 5. section 3.1 SFL Control Message > Regarding the 'Control Code', do we allocate specific value for the = query/response actions? For example, we can have request (control code =3D= 0), refresh (control code =3D 1) and withdraw (control code =3D2) for a = query. Currently there is no such allocations. Thank you for noting that.

Hi, All,
 
Happy new year = to you all.
 
I am another = MPLS-RT reviewer for this document, and would like to follow up in this = thread, by starting from reviewing the latest = draft-bryant-mpls-sfl-control-05. Generally I think this is a complete = work with self-contained solution, and I assume the importance of the = document has been evaluated by the WG chairs and experts. Some comments = are listed below as a =E2=80=98MPLS beginner=E2=80=99J
 
1.       Section 1 = Introduction
"well managed" = should be "well-managed"; -> this also applies for section 7 security = considerations.
 "withdrawn" should be "withdraw", -> this also = applies for the abstract = text.

Withdrawn correction done.

I have put the hyphens in, but I am not sure = whether they are required. 

 
2. The RFC6374 = looks slightly different than other RFC citations, as the '[]' is = missing; please check the = formatting.

Thanks for picking that I. I regenerated the .mkd from = a .txt file and missed that reference. More importantly the RFC was not = in the reference list at the end of the document.

It is now fixed in -06.


 
3. section 3.1 = SFL Control Message
I am curious on the bits allocation "26-bit Session = Identifier" and "6-bit SFL Batch", which is not typical (my intuitive is = 24+8), and there is no reason in the explanation text below the TLV. We = need to confirm 1) the allocation is intended to be 26+6; 2) add = something to the TLV explanation, for = example:


The choice of the 26 bit = size is inherited from RFC 6374 and needs to be the same.

I have added in the (6-bits) because it is = unusual, but it is obvious from the figure and we do not specify the = size of any of the other fields.

The = use of 6 bits was a compromise. Strictly the protocol would work without = it, but at the cost of extra messages and extra state. Allowing the use = of a 6-bit batch identifier is convenient in that it reuses the DS field = in the RFC6374 structure. If we had made it larger we would have needed = to use an additional longword in the protocol.

A batch size of 64 seemed a good engineering = compromise when we drew up the design.


 
OLD:
SFL = Batch      Used where the SFLs for this Session = Identifier
          &nb= sp;    managed across multiple SFL Control = Messages.  A given
          &nb= sp;    set of SFLs MUST be retained in the same = batch.
NEW:
SFL Batch (6 bits) Used = where the SFLs for this Session Identifier
          &nb= sp;       managed across multiple SFL = Control Messages.  A given
          &nb= sp;       set of SFLs MUST be retained in = the same batch. 
 

Done


4. section 3.1 SFL = Control Message
Regarding the = flags, my understanding is that the intention is to use the first bit to = indicate query/respond, and pad the other 3 bits as 0. The processing of = '0' bits is understood as "MUST be set to 0 by sender and ignored by = receiver". Is it correct? If yes, the following statement may be = easier:
OLD:
Flags: The format of = the Flags field is shown below.
 
          &nb= sp;            = ;       +-+-+-+-+
          &nb= sp;            = ;       |R|0|0|0|
          &nb= sp;            = ;       +-+-+-+-+
 
          &nb= sp;            = ; SFL Control Message Flag
 
   = R: Query/Response indicator.  Set to 0 for a Query and 1 for a
      Response.
 
   = 0: Set to zero by the Sender and ignored by the Receiver.
 
NEW:
Flags (4 bits): The = first bit is set to 0 for a query and 1 for a
response; the next 3 = bits MUST be set to 0 by the Sender and ignored
by the Receiver.
 

Remember that this is inherited from RFC 6374 and = I have tried to use a similar presentation of information.

I have tidied the text a little to mirror the RFC = 6374 layout.

I really do not think = it is necessary to say 4-bits.


It now looks like this - not sure it it is back to = where it started:

 Flags: = The format of the Flags field is shown below.

              =             =  +-+-+-+-+
            =               =  |R|0|0|0|
            =               =  +-+-+-+-+

      =               SFL Control Message = Flags.

The meanings of the flag bits = are:

    R: Query/Response = indicator.  Set to 0 for a Query and set
    =    to 1 for a Response.

    0: Set to zero by the Sender and = ignored by the Receiver.

Note that this then style matches the text that = follows.



 
5. section 3.1 = SFL Control Message
Regarding the 'Control Code', do we allocate specific value = for the query/response actions? For example, we can have request = (control code =3D 0), refresh (control code =3D 1) and withdraw (control = code =3D2) for a query. Currently there is no such = allocations.

Thank you for noting that. That is the most = important review comment. I will address it in a separate = email.


 
6. section = 3.2.1.  Request/Grant
In the first paragraph, when you say 'It sets ...' and 'It = chooses ...', does the =E2=80=9Cit=E2=80=9D refer the Querier?
This problem confused = me some times in later sections as = well.

I have worked on this a bit and changed most of = the =E2=80=9CIt=E2=80=9D to Querier or Responder as = appropriate.

 
7. section 4. = Return Path
'mulit-point' = -> 'multi-point'
The usage of comma and bracket confused me, does it mean the = following?
Where the MPLS = LSP  (or other construct) is a multi-point to point or
multi-point to = multi-point, the RFC6374 Address TLV MUST be included
in Query packet even if = the response is requested in-band, since it is
necessary to provide = the necessary return address for this = request.

I have clarified this.

Thank you for the review

Best wishes

Stewart

 
Thank you.

I have added a line to the Introduction.

The earlier = references are in text that I included as a figure to force the layout = style I wanted, and the markdown compiler ignores references in figures. = The compiling process excluded unused references so they have to be = forced. I have changed the text to

RFC = Editor please remove this note which is used to force the following = references to appear {{RFC3032}} {{RFC5036}}

After reading it, I have the following comments on it: 1. Since the SFL control protocol uses ACH =96 the SFL control messages flo= w in-band over the MPLS datapath (e.g. PW, LSP, etc.). Is this restriction = required? How does it differ from other protocol(s) that do out-of-band con= trol messaging -- e.g. BGP, T-LDP, etc. that allocate PW labels? 2. It would be useful to have text for any considerations/comparison given = to existing control plane protocols that can do same/similar function and i= f/why they are not adopted/extended 3. Section 3 mentions, the SFL ACH can be carried over PW, or LSP. What abo= ut MPLS section/i.e. MPLS link? E.g. for use with single-hop LM? Any restri= ctions for this? 4. Section 3.1: a. Some flags may be meaningful at one side (i.e. either querier or respon= der) and depending if CC flag is R set or not -- some flags may be invalid = if received - e.g. W Lflag is not expected to be received by a querier. Do = such cases necessitate errors? How is it handled - rejecting the whole SFL = batch or the whole SFL message? b. s/Responser/Responder 5. Section 3.2.1 a. May clarify that =93SFL Control Request=94 message, is =93SFL Control M= essage=94 with CC Flag (R=3D1) b. Can the same message serve as Request, Refresh and Withdraw for a speci= fic Batch? i.e. to allow existing (allocated) SFL batch to be resized by re= freshing some existing SFL(s), withdrawing some, and requesting some new on= es? If yes, may clarify it - since as-is the sections defined in the docume= nt hint that a message can be one of (request/refresh/withdraw) at any time c. In cases where a node functions as both requester and responder, can s= ame session Id be used for sending requests and respond by the same node? d. As per https://tools.ietf.org/html/draft-ietf-mpls-sfl-framework, the h= igh runner case for SFL is for additional action packet counter - is this a= ction assumed implicit always for all SFL(s)? Is there a way in the protoco= l to associate different/additional action with a specific SFL? e. =93A Querier MUST NOT send an expired SFL to a Responder since to do so= may invalidate another SFL operation.=94: this may be considered a securit= y for a DoS, you may want to highlight this in the security section f. s/SFV/SFL g. The text =93All other LFlags are cleared.=94 Seem to override the previ= ous text that. V LFlag can be also set at same time to cover requesting a s= pecific label 6. For unidirectional LSP(s), how is the return path for response messages = specified? Is the Querier source address derived from LSP control plane sta= te? Or, is the SA TLV from RFC6374 for p2p unidirectional added too? In thi= s case, how to force the SFL Control Response message =96 e.g. be IP routed= back or go over a specific reverse LSP? 7. "3.2.3. Withdraw =20 [...] via an appropriate path.", does this mean control messages= can be sent over any path (other than the underlying LSP or PW)? 8. " A Querier MUST wait a configured time (suggested wait of 60 seconds) before reattempting a Withdraw request.", may be useful to highlight why= the restriction? Is this to avoid frequent sending of control plane messag= ing?

This draft is a work item of the Multiprotocol Label Switching WG of the IETF. Title : A Simple Control Protocol for MPLS SFLs Authors : Stewart Bryant George Swallow Siva Sivabalan Filename : draft-bryant-mpls-sfl-control-06.txt Pages : 13 Date : 2020-01-03 Abstract: In draft-ietf-mpls-sfl-framework the concept of MPLS synonymous flow labels (SFL) was introduced.

Working Group,

This is to initiate a "two week" working group last call on
draft-ietf-mpls-base-yang.

Mote: We are allowing for the holiday season and intend to close the
wglc on Friday January 10, 2020.

Please send your comments to the mpls wg mailing list (mpls@ietf.org).

There are no IPR disclosures against draft-ietf-mpls-rmr.

Both the authors and the contributors have stated on the working group
mailing list that they are unaware of any non-disclosed IPRs that
relates to this document.

This working group last call ends Friday January 10, 2020.

This draft is a work item of the Multiprotocol Label Switching WG of the IETF. Title : RSVP-TE Summary Fast Reroute Extensions for LSP Tunnels Authors : Mike Taillon Tarek Saad Rakesh Gandhi Abhishek Deshmukh Markus Jork Vishnu Pavan Beeram Filename : draft-ietf-mpls-summary-frr-rsvpte-08.txt Pages : 21 Date : 2020-01-12 Abstract: This document updates RFC 4090 for the Resource Reservation Protocol (RSVP) Traffic-Engineering (TE) procedures defined for facility backup protection. The updates include extensions that reduce the amount of signaling and processing that occurs during Fast Reroute (FRR), and subsequently, improves scalability when undergoing FRR convergence after a link or node failure. These extensions allow the RSVP message exchange between the Point of Local Repair (PLR) and the Merge Point (MP) to be independent of the number of protected Label Switched Paths (LSPs) traversing between them when facility bypass FRR protection is used. The signaling extensions are fully backwards compatible with nodes that do not support them.

I had an off-line mail asking for more time, but since the time is up and I haven't heard anything based on that request it is time to close. This working group last call is closed. There have been comments, the authors should address the comments and work with the reviewers so they are comfortable with how we handle the comment. Post a new version as necessary. /Loa MPLS WG Co-chair On 19/12/2019 18:22, Loa Andersson wrote: > Working Group, > > This is to initiate a "two week" working group last call on > draft-ietf-mpls-base-yang. > > Mote: We are allowing for the holiday season and intend to close the > wglc on Friday January 10, 2020. > > Please send your comments to the mpls wg mailing list (mpls@ietf.org). > > There are no IPR disclosures against draft-ietf-mpls-rmr. > > Both the authors and the contributors have stated on the working group > mailing list that they are unaware of any non-disclosed IPRs that > relates to this document. > > This working group last call ends Friday January 10, 2020. > > /Loa > mpls wg co-chair -- Loa Andersson email: loa@pi.nu Senior MPLS Expert Bronze Dragon Consulting phone: +46 739 81 21 64 From nobody Sat Jan 25 19:58:48 2020 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 BADE112001E; Sat, 25 Jan 2020 19:58:45 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -1.898 X-Spam-Level: X-Spam-Status: No, score=-1.898 tagged_above=-999 required=5 tests=[BAYES_00=-1.9, SPF_HELO_NONE=0.001, SPF_NONE=0.001] autolearn=ham autolearn_force=no Received: from mail.ietf.org ([4.31.198.44]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 4R9dIkOWcOO9; Sat, 25 Jan 2020 19:58:44 -0800 (PST) Received: from pipi.pi.nu (pipi.pi.nu [83.168.239.141]) (using TLSv1.1 with cipher AECDH-AES256-SHA (256/256 bits)) (No client certificate requested) by ietfa.amsl.com (Postfix) with ESMTPS id 0205E12001B; Sat, 25 Jan 2020 19:58:43 -0800 (PST) Received: from [192.168.1.6] (unknown [119.94.173.58]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (No client certificate requested) (Authenticated sender: loa@pi.nu) by pipi.pi.nu (Postfix) with ESMTPSA id 159C63640D1; Sun, 26 Jan 2020 04:58:40 +0100 (CET) To: tom petch , "mpls@ietf.org" Cc: "mpls-chairs@ietf.org" , "draft-ietf-mpls-base-yang@ietf.org" References: <2e2ce194-ed62-d225-ca7e-97e373c9c5c9@pi.nu> From: Loa Andersson Message-ID: Date: Sun, 26 Jan 2020 11:58:35 +0800 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:68.0) Gecko/20100101 Thunderbird/68.4.1 MIME-Version: 1.0 In-Reply-To: Content-Type: text/plain; charset=utf-8; format=flowed Content-Language: en-US Content-Transfer-Encoding: 7bit Archived-At: Subject: Re: [mpls] MPLS wglc draft-ietf-mpls-base-yang X-BeenThere: mpls@ietf.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Multi-Protocol Label Switching WG List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 26 Jan 2020 03:58:46 -0000 Tom, Thanks for cataching this, yes it is true that there are no IPR disclosures against draft-mpls-base yang.
