This draft is a work item of the Common Control and Measurement Plane Working Group of the IETF. Title : General Network Element Constraint Encoding for GMPLS Controlled Networks Authors : Greg M. Bernstein Young Lee Dan Li Wataru Imajuku Filename : draft-ietf-ccamp-general-constraint-encode-18.txt Pages : 31 Date : 2015-02-02 Abstract: Generalized Multiprotocol Label Switching can be used to control a wide variety of technologies. In some of these technologies, network elements and links may impose additional routing constraints such as asymmetric switch connectivity, non-local label assignment, and label range limitations on links. This document provides efficient, protocol-agnostic encodings for general information elements representing connectivity and label constraints as well as label availability. It is intended that protocol-specific documents will reference this memo to describe how information is carried for specific uses.

For instance, if we have one source (port 1) and one destination (port 2) with two labels > each. Then we would have: {(1,1,2,1), (1,1,2,2), (1,2,2,1), (1,2,2,2)} I think with the current statement, we can send this info in any combination > of multiple matrices, which I think perfectly fine. With your suggestion, I would not be able send (1,1,2,1) and (1,1,2,2) together. Why would this > not be made possible? My take is as long as each submatrix represents a set of disjoint quadruples, that should be allowed. > My reading of "two matrices will not have the same {src port, src label, dst port, dst label}" is as follows. > > > > input port=1 --> Submatrix#1 --> output port=2 > input label=1 output label=1 > > input port=1 --> Submatrix#2 --> output port=2 > input label=1 output label=2 > > This is allowed. > > > > input port=1 --> Submatrix#1 --> output port=2 > input label=1 output label=1 > > input port=1 --> Submatrix#2 --> output port=2 > input label=1 output label=1 > > This is not allowed. > > > > input port=1 --> Submatrix#1 --> output port=2 > input label=1 output label=1 > > input port=1 --> Submatrix#2 --> output port=2 > input label=2 output label=2 > > This is allowed. > > Is above understanding correct? > If so, I am not sure how example A works, since I am not sure what is the indentifier to direct from input to each submatrix. > > Maybe I am mis-understanding what sub-matrix is. I thought sub-matrix is a sort of virtual node, splitting the single matrix (or switch) into smaller pieces. Can you explain how the revised text clarifies this point? Thanks, Lou > ....

preceding text: ... There may be more than one matrix associated with a node as the node can partition the switch matrix into several sub- matrices for various reasons such as incremental updates, etc. When the matrix is partitioned into sub-matrices, it is envisioned that they are mutually exclusive to one another in representing which ports/labels are associated with each sub-matrix. This implies that two matrices will not have the same {src port, src label, dst port, dst label}. I'd suggest directly addressing the ambiguity by revising the first sentence and "for various reasons such as incremental updates, etc. " in particular. Perhaps "primarily to limit the size of any individual information element used to represent the matrix." or however else you'd like to capture the intent.

The answer was no, and sub-matrix is simply a partition of connectivity matrix into smaller pieces.

How about: There may be more than one Field associated with a node as a node can partition the switch matrix into several sub- matrices. This partitioning is primarily to limit the size of any individual information element used to represent the matrix and to enable incremental updates. When the matrix is partitioned into sub-matrices, each sub-matrix will be mutually exclusive to one another in representing which ports/labels are associated with each sub-matrix. This implies that two matrices will not have the same {src port, src label, dst port, dst label}. Each sub-matrix is identified via a different Matrix ID which MUST represent a unique combination of {src port, src label, dst port, dst label}. Lou > Would this be Ok with you? Then I will publish a revision upon your approval. Also we need to hear from Tomonori on if his issues is addressed.

Bernstein Young Lee Dan Li Wataru Imajuku Filename : draft-ietf-ccamp-general-constraint-encode-19.txt Pages : 31 Date : 2015-02-03 Abstract: Generalized Multiprotocol Label Switching can be used to control a wide variety of technologies. In some of these technologies, network elements and links may impose additional routing constraints such as asymmetric switch connectivity, non-local label assignment, and label range limitations on links. This document provides efficient, protocol-agnostic encodings for general information elements representing connectivity and label constraints as well as label availability. It is intended that protocol-specific documents will reference this memo to describe how information is carried for specific uses.

Title : Routing and Wavelength Assignment Information Encoding for Wavelength Switched Optical Networks Authors : Greg M. Bernstein Young Lee Dan Li Wataru Imajuku Filename : draft-ietf-ccamp-rwa-wson-encode-27.txt Pages : 40 Date : 2015-02-04 Abstract: A wavelength switched optical network (WSON) requires that certain key information elements are made available to facilitate path computation and the establishment of label switching paths (LSPs). The information model described in "Routing and Wavelength Assignment Information for Wavelength Switched Optical Networks" shows what information is required at specific points in the WSON.

Abstract A wavelength switched optical network (WSON) requires that certain key information elements are made available to facilitate path computation and the establishment of label switching paths (LSPs). The information model described in "Routing and Wavelength Assignment Information for Wavelength Switched Optical Networks" shows what information is required at specific points in the WSON. Part of the WSON information model contains aspects that may be of general applicability to other technologies, while other parts are specific to WSONs. This document provides efficient, protocol-agnostic encodings for the WSON specific information elements. It is intended that protocol-specific documents will reference this memo to describe how information is carried for specific uses. Such encodings can be used to extend GMPLS signaling and routing protocols.

So perhaps something like... x. Manageability Considerations No existing management tools handle the additional TE parameters as defined in this document and distributed in OSPF-TE. The existing MIB module contained in [RFC6825] allows the TE information distributed by OSPF-TE to be read from a network node: this MIB module could be augmented (possibly by a sparse augmentation) to report this new information. The current environment in the IETF favors NETCONF [RFC6241] and YANG [RFC6020] over SNMP and MIB modules. Work is in progress in the TEAS working group to develop a YANG module to represent the generic TE information that may be present in a Traffic Engineering Database (TED). This model may be extended to handle the additional information described in this document to allow that information to be read from network devices or exchanged between consumers of the TED. Furthermore, links state export using BGP (BGP-LS) [draft-ietf- idr-ls-distribution] enables the export of TE information from a network using BGP. Work could realistically be done to extend BGP-LS to also carry the information defined in this document. It is not envisaged that the extensions defined in this document will place substantial additional requirements on Operations, Management, and Administration (OAM) mechanisms currently used to diagnose and debug OSPF systems. However, tools that examine the contents of opaque LSAs will need to be enhanced to handle these new sub-TLVs. Edit this to read the way you want it to, and post a revision.

This draft is a work item of the Common Control and Measurement Plane Working Group of the IETF. Title : OSPF-TE Extensions for General Network Element Constraints Authors : Fatai Zhang Young Lee Jianrui Han Greg Bernstein Yunbin Xu Filename : draft-ietf-ccamp-gmpls-general-constraints-ospf-te-09.txt Pages : 14 Date : 2015-02-11 Abstract: Generalized Multiprotocol Label Switching (GMPLS) can be used to control a wide variety of technologies including packet switching (e.g., MPLS), time-division (e.g., SONET/SDH, Optical Transport Network (OTN)), wavelength (lambdas), and spatial switching (e.g., incoming port or fiber to outgoing port or fiber). In some of these technologies, network elements and links may impose additional routing constraints such as asymmetric switch connectivity, non- local label assignment, and label range limitations on links.

So perhaps something like... x. Manageability Considerations No existing management tools handle the additional TE parameters as defined in this document and distributed in OSPF-TE. The existing=20 MIB module contained in [RFC6825] allows the TE information=20 distributed by OSPF-TE to be read from a network node: this MIB=20 module could be augmented (possibly by a sparse augmentation) to report this new information. The current environment in the IETF favors NETCONF [RFC6241] and YANG [RFC6020] over SNMP and MIB modules. Work is in progress in the TEAS working group to develop a YANG module to represent the generic TE=20 information that may be present in a Traffic Engineering Database=20 (TED). This model may be extended to handle the additional=20 information described in this document to allow that information to=20 be read from network devices or exchanged between consumers of the TED. Furthermore, links state export using BGP (BGP-LS) [draft-ietf- idr-ls-distribution] enables the export of TE information from a=20 network using BGP. Work could realistically be done to extend BGP-LS to also carry the information defined in this document. It is not envisaged that the extensions defined in this document will place substantial additional requirements on Operations, Management, and Administration (OAM) mechanisms currently used to diagnose and=20 debug OSPF systems. However, tools that examine the contents of opaque LSAs will need to be enhanced to handle these new sub-TLVs. Edit this to read the way you want it to, and post a revision.

Please send substantive comments to the ietf@ietf.org mailing lists by 2015-02-26. 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 Generalized Multiprotocol Label Switching (GMPLS) can be used to control a wide variety of technologies including packet switching (e.g., MPLS), time-division (e.g., SONET/SDH, Optical Transport Network (OTN)), wavelength (lambdas), and spatial switching (e.g., incoming port or fiber to outgoing port or fiber). In some of these technologies, network elements and links may impose additional routing constraints such as asymmetric switch connectivity, non- local label assignment, and label range limitations on links. This document describes Open Shortest Path First (OSPF) routing protocol extensions to support these kinds of constraints under the control of GMPLS.

Title : Framework and Requirements for GMPLS-based control of Flexi-grid DWDM networks Authors : Oscar Gonzalez de Dios Ramon Casellas Fatai Zhang Xihua Fu Daniele Ceccarelli Iftekhar Hussain Filename : draft-ietf-ccamp-flexi-grid-fwk-03.txt Pages : 40 Date : 2015-02-23 Abstract: To allow efficient allocation of optical spectral bandwidth for high bit-rate systems, the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) has extended its Recommendations G.694.1 and G.872 to include a new dense wavelength division multiplexing (DWDM) grid by defining a set of nominal central frequencies, channel spacings and the concept of "frequency slot". In such an environment, a data plane connection is switched based on allocated, variable-sized frequency ranges within the optical spectrum creating what is known as a flexible grid (flexi- grid). This document defines a framework and the associated control plane requirements for the GMPLS-based control of flexi-grid DWDM networks.

This draft is a work item of the Common Control and Measurement Plane Working Group of the IETF. Title : General Network Element Constraint Encoding for GMPLS Controlled Networks Authors : Greg M. Bernstein Young Lee Dan Li Wataru Imajuku Filename : draft-ietf-ccamp-general-constraint-encode-20.txt Pages : 31 Date : 2015-02-23 Abstract: Generalized Multiprotocol Label Switching can be used to control a wide variety of technologies. In some of these technologies, network elements and links may impose additional routing constraints such as asymmetric switch connectivity, non-local label assignment, and label range limitations on links. This document provides efficient, protocol-agnostic encodings for general information elements representing connectivity and label constraints as well as label availability. It is intended that protocol-specific documents will reference this memo to describe how information is carried for specific uses.

The IESG contact persons are Alia Atlas and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ccamp-general-constraint-encode/ Technical Summary Generalized Multiprotocol Label Switching can be used to control a wide variety of technologies. In some of these technologies, network elements and links may impose additional routing constraints such as asymmetric switch connectivity, non-local label assignment, and label range limitations on links. This document provides efficient, protocol-agnostic encodings for general information elements representing connectivity and label constraints as well as label availability. It is intended that protocol-specific documents will reference this memo to describe how information is carried for specific uses. Working Group Summary This topic has been discussed in the WG for a very long time, perhaps 6 years. Support for the work has been tepid, but there are multiple sets of contributors who would like to see the work result in proposed standards. This document was updated after detailed reviews by the document shepherd and responsible AD. Document Quality This document provides background and an approach to extending exiting RFCs for which there are implementations, but does not itself define any protocol mechanisms. The existing RFCs include RFC3471, RFC3473, RFC4202, RFC4203. This work is based on RFC6163. A number of subsequent documents related to signalling and routing for Wavelength Switched Optical Networks (WSON) have dependencies on the generic mechanisms defined in this document. Personnel Lou Berger is the document Shepherd. Adrian Farrel is the Responsible Area Director.

This draft is a work item of the Common Control and Measurement Plane Working Group of the IETF. Title : Routing and Wavelength Assignment Information Encoding for Wavelength Switched Optical Networks Authors : Greg M. Bernstein Young Lee Dan Li Wataru Imajuku Filename : draft-ietf-ccamp-rwa-wson-encode-28.txt Pages : 39 Date : 2015-02-24 Abstract: A wavelength switched optical network (WSON) requires that certain key information fields are made available to facilitate path computation and the establishment of label switching paths (LSPs). The information model described in "Routing and Wavelength Assignment Information for Wavelength Switched Optical Networks" shows what information is required at specific points in the WSON. Part of the WSON information model contains aspects that may be of general applicability to other technologies, while other parts are specific to WSONs. This document provides efficient, protocol-agnostic encodings for the WSON-specific information fields. It is intended that protocol- specific documents will reference this memo to describe how information is carried for specific uses. Such encodings can be used to extend GMPLS signaling and routing protocols. In addition these encodings could be used by other mechanisms to convey this same information to a path computation element (PCE).

Hi, Rajan,

 

    As I was not involved earlier, I find the foll= owing may be  a bit long for others in the WG to get involved.  B= efore I dive into the discussion and share my thoughts, am I accurate if I recap the question as:

 

   You think the existing = text in draft-ietf-ccamp-flexible-grid-ospf-ext-01 do not support the follo= wing:

1)      Do not support priority;

2)      Do not convey the min & max LSP bandwidth information= in the SCSI field;

 

Could you confirm my interpretation of your issue?

 

The following is my thoughts ( subject to change if the question = I recapped above is not as exact as what you want to say):

 

The  current method is to reuse what has already been propos= ed for WSON. So it reuses the SCSI field defined in WSON-OSPF draft (https://tools.ietf.org/html/draft-ietf-ccamp-wson-sig= nal-compatibility-ospf-15#section-3.1). So, it DOES support priority (see the details are in [GEN-ENCODE] draft-ie= tf-ccamp-general-constraint-encode-20). Exactly because of the same reason,= the draft under discussion uses label set field to describe what frequency= slots are available. So, although it allows for all different varieties supported by [GEN-ENCODE] (i.e., lis= t, bitmap, inclusive, exclusive etc.), the method does not see the need of = specify the max&min LSP bandwidth since it can be naturally deduced fro= m the available frequency spectrum information conveyed.  

 

The above discussion actually reminds me of a question Ramon rais= ed up a while ago among the authors of this draft, what has been defined in= WSON-OSPF is truly usable labels in signaling. But with Flexi-grid, it is not true anymore. For example, although we use = Inclusive Label Range to describe available frequency range, say the exampl= e in Section 4.4 of  draft-ietf-ccamp-flexible-grid-ospf-ext-01 (assum= e m=3D1), none of these labels are directly usable if what is actually requested is a bandwidth with m=3D2.  I my= self do not see any issue as long as we make it clear we use the format jus= t to describe what resource available NOT usable labels. Since it is a WG d= raft, it is worthwhile to solicit what you think?

 

Cheers,
Xian

The pri= ority in each layer is independent.  The intent of explicitly carrying= priority info in the advertisement is to allow for LSP creation at differe= nt priorities.  Note that priority defined in OTN RFC don=A1=AFt apply here as it is a different layer.   Y= ou can have L0-LSP setup at priority-1 but L1-Telink (OTN link) formed out = of this may advertise all 8 or subset of them.  It is an implementatio= n choice.  I don=A1=AFt see any conflicts here.

&n= bsp;

Once we= agree on the following items we can figure out TLV encoding options.<= /o:p>

&n= bsp;

1.      Allow for Advertisement of Min & Max slot widths at different prioriti= es =A8C up to 8

2.      Min/Max slot width field =A8C 16 bit instead of 8  (I see you are agr= eeing to this change below)

3.      Max LSP Bandwidth =A8C this was debated in previous meetings but no firm c= onclusion.

Hi, Rajan,

 

Thanks for the information, I noticed there is a change talking a= bout extending Flexi-grid data plan to satisfy requirements in RFC4202. I f= orward this email to all the authors of OSPF draft to advertise your commentsJ  <= /p>

 

Firstly let=A1=AFs recall the sub-TLV format in draft-dhillon-cca= mp-flexgrid-ospfte-ext as follow:

 

  0        =            1  &= nbsp;           &nbs= p;    2         = ;          3=

   +-------------------------= --------------------------------------+

   |     = ;    Min Slot Width       = ; |       Max Slot Width   &nb= sp;      |

   +-+-+-+-+-= +-+-+-+-+-+-+-+-+-+-+-+-= 3;-+-+-+-+-+-+-+-+-+-+-+-+-= +-+-+

 

Then I share my understanding on your concern. Compared with sub-= TLV in section 4.3 of draft-ietf-ccamp-flexible-grid-ospf-ext-01, I highlig= ht the difference as follow:

 

In your proposal,

1)      Slice Spacing is preferred to be carried in the  sub= -TLV;

2)      Priority bits are preferred to be included in sub-TLV;

3)      Min/Max Widths should both be 16-bit;

4)      N-start and Num of Slices to represent the spectrum rathe= r than C.F.G and S.W.G;

 

Below please find my comments:

Firstly I believe both of your structure and the current structur= e in WG draft are satisfying the requirement of flexi-grid FWK draft (the i= nfo model in Fig. 17). We only need to deal with some differences in representation format, and some additional i= nformation may be useful.

 

1)      Different slice spacing is applicable but may not be nece= ssary; the spirit to introduce flexible grid is to allow flexibility in spe= ctrum allocation and current WG draft can satisfy the requirement. Not much further advantage for using slice sp= acing;

2)      Priority bits: I agree that it is widely used, I am basic= ally fine to include priority bits in the sub-TLV. My only concern is, ther= e are also such priority information in other place (for example OTN BW sub-TLV in Section 4.1.3 in RFC7138), d= o we need to repeat here? What is the relationship if we have two prioritie= s? Is it possible the OTN priority is not consistent with flexi-grid priori= ty? Why? And How to deal with this?

3)      Agreed, will change both the min/max widths to 16-bit in = the next version;

4)      Personally I don=A1=AFt think it=A1=AFs necessary to chan= ge the current WG draft: I think your proposed representation can have equi= valent result as the one in current WG draft;

 

Rajan, please correct me if there is misunderstanding, also let m= e know if you have other comments.

 

All, please feel free to comments, or we move to the list if nece= ssaryJ

 

Best wishes,

Haomian

Hi, Rajan,=

 

Firstly sorry for the very l= ate response.

 

For your first concern, I se= e some difference in TLVs about priority issue (Table I in your draft). I t= hink I understand your description but I didn't find very much advantage to= include such 'scalable' settings.

&= nbsp;

RR&g= t;> Priority based advertisement is pretty standard mechanism used in al= l existing RFCs.  For e.g. you can find these in WSON, OTN  docs = and any other Te-extensions draft.

 

Another concern from me is, = for the flexi-grid literature, there are more than one WG draft, I think it= 's better to consider such case in fwk draft, and after that the OSPF one c= an revise accordingly. P.S, I don't know whether this topic was discussed on the list before (perhaps there ar= e some conclusions, let me know). If not, I would like to suggest move to t= he list.

 

RR&g= t;> I looked at framework.  Yes, it doesn=A1=AFt talk about priorit= y based advertisement.  Thanks for pointing this out. Good catch. We w= ill provide this comment to FWK authors & CC you.  I do not see any issue updating the fwk doc with this detail.   

 

For your second concern on M= ax LSP Bandwidth, my understanding is you are trying to use the description= in section 3.2 of your draft to replace the one in section 4.3 of current = WG draft. Is this true? I believe the description in your draft is clear and correct. BTW, I noticed bit differe= nce in Min Bandwidth (16 bits allocated in your draft and 8 bit in current = WG draft), hopefully this will not be a big issue (8 bit support a bandwidt= h up to 3200GHz, which is absolutely more than the normal requirement for a minimal BW).

 

RR&g= t;>  Yes, I was referring to section 3.2 in our draft.   =

We w= ent with 16-bit fields for Min & Max fields as the values for these fie= lds range from 0 =A8C 384.  We tried to address the case of using full= spectrum BW as one LSP.  This is an extreme case but can=A1=AFt be ruled out.

 

Pl l= et me know if you have any other comments.

Thanks.

 

Best wishes,

Haomian

Haomian,

 

As I had mentioned we are no= longer pushing for SuperChannel in the draft.  So, this should make i= t easier to merge the docs.

 

In my view there are couple = of areas your draft doesn't address which can be taken from our draft:=

 

1.  You have separated = Max & Min Slot width in Port Label restriction sub-TLV.  This is O= .K. But this doesn't allow for priority based Min/Max usage.   Ou= r draft allows for this flexibility which can be used.

2.  Max LSP Bandwidth f= ield definition can be taken from our doc.

 

The priority handling can be= further simplified by merging slice info & Min/Max fields in to a sing= le sub-TLV if other authors agree.

 

Pl let me know.

 

Thx

Rajan

Xian,

 

I understand this doc = is trying to reuse GEN-ENCODE & ther= e is support for priority.  I am not referring to this one.  The = Min Width & Max  Width fields do exist in the draft but these alon= e are not sufficient. We need info per priority for the following reason.

=  

The i= ntent of Min & Max width info is to specify what is the Minimum/Maximum= LSP bandwidth an LSP could reserve at a given priority =A1=AEp=A1=AF on th= e link.  You can draw parallel to =A1=AEMinimum LSP Bandwidth=A1=AF & =A1=AEMaximum LSP Bandwidth=A1=AF fields in RFC 4202.   

=  

I don= =A1=AFt understand how you can derive this from label set field.  &nbs= p;Availability of  =A1=AEN=A1=AF consecutive labels doesn=A1=AFt mean = you can setup an LSP with a size of =A1=AEN=A1=AF.

Thx

Hi, R= ajan,

=  

 = ;   As I was not involved earlier, I find the following may be &n= bsp;a bit long for others in the WG to get involved.  Before I dive in= to the discussion and share my thoughts, am I accurate if I recap the question as:

=  

   You think the existing text in draft-i= etf-ccamp-flexible-grid-ospf-ext-01 do not support the following:

1)      Do not support priority;

2)      Do not convey the min & max LSP bandwidth information in the SCSI fi= eld;

=  

Could= you confirm my interpretation of your issue?

=  

The f= ollowing is my thoughts ( subject to change if the question I recapped abov= e is not as exact as what you want to say):

=  

The&n= bsp; current method is to reuse what has already been proposed for WSON. So= it reuses the SCSI field defined in WSON-OSPF draft (https://tools.ietf.org/html/draft-ietf-ccamp-wson-signal-compatibili= ty-ospf-15#section-3.1). So, it DOES support priority (see the details are in [GEN-ENCODE] draft-ie= tf-ccamp-general-constraint-encode-20). Exactly because of the same reason,= the draft under discussion uses label set field to describe what frequency= slots are available. So, although it allows for all different varieties supported by [GEN-ENCODE] (i.e., lis= t, bitmap, inclusive, exclusive etc.), the method does not see the need of = specify the max&min LSP bandwidth since it can be naturally deduced fro= m the available frequency spectrum information conveyed.  

=  

The a= bove discussion actually reminds me of a question Ramon raised up a while a= go among the authors of this draft, what has been defined in WSON-OSPF is t= ruly usable labels in signaling. But with Flexi-grid, it is not true anymore. For example, although we use Incl= usive Label Range to describe available frequency range, say the example in= Section 4.4 of  draft-ietf-ccamp-flexible-grid-ospf-ext-01 (assume m= =3D1), none of these labels are directly usable if what is actually requested is a bandwidth with m=3D2.  I my= self do not see any issue as long as we make it clear we use the format jus= t to describe what resource available NOT usable labels. Since it is a WG d= raft, it is worthwhile to solicit what you think?

=  

Cheer= s,
Xian

Hi all,

 

This is a really inter= esting discussion and since we=A1=AFre speaking about a working group draft= I think we should continue con the mailing list.

Please include the WG = in your reply.

Haomian,

 

The priority in each l= ayer is independent.  The intent of explicitly carrying priority info = in the advertisement is to allow for LSP creation at different priorities.&= nbsp; Note that priority defined in OTN RFC don=A1=AFt apply here as it is a different layer.   You can have L0-LSP set= up at priority-1 but L1-Telink (OTN link) formed out of this may advertise = all 8 or subset of them.  It is an implementation choice.  I don= =A1=AFt see any conflicts here.

 

Once we agree on the f= ollowing items we can figure out TLV encoding options.

 

1. &nbs= p;    Allow for Adve= rtisement of Min & Max slot widths at different priorities =A8C up to 8=

2. &nbs= p;    Min/Max slot w= idth field =A8C 16 bit instead of 8  (I see you are agreeing to this c= hange below)

3. &nbs= p;    Max LSP Bandwi= dth =A8C this was debated in previous meetings but no firm conclusion.

  

Thx<= /p>

Rajan

Hi, R= ajan,

=  

Thank= s for the information, I noticed there is a change talking about extending = Flexi-grid data plan to satisfy requirements in RFC4202. I forward this ema= il to all the authors of OSPF draft to advertise your commentsJ

First= ly let=A1=AFs recall the sub-TLV format in draft-dhillon-ccamp-flexgrid-osp= fte-ext as follow:

   +-+-+-+-+-+-+-+-= 3;-+-+-+-+-+-+-+-+-+-+-+-+-= +-+-+-+-+-+-+-+-+-+-+-+

=  

Then = I share my understanding on your concern. Compared with sub-TLV in section = 4.3 of draft-ietf-ccamp-flexible-grid-ospf-ext-01, I highlight the differen= ce as follow:

=  

In yo= ur proposal,

1)      Slice Spacing is preferred to be carried in the  sub-TLV;

2)      Priority bits are preferred to be included in sub-TLV;=

3)      Min/Max Widths should both be 16-bit;

4)      N-start and Num of Slices to represent the spectrum rather than C.F.G an= d S.W.G;

=  

Below= please find my comments:

First= ly I believe both of your structure and the current structure in WG draft a= re satisfying the requirement of flexi-grid FWK draft (the info model in Fi= g. 17). We only need to deal with some differences in representation format, and some additional information may = be useful.

=  

1)      Different slice spacing is applicable but may not be necessary; the spir= it to introduce flexible grid is to allow flexibility in spectrum allocatio= n and current WG draft can satisfy the requirement. Not much further advantage for using slice spacing; =

2)      Priority bits: I agree that it is widely used, I am basically fine to in= clude priority bits in the sub-TLV. My only concern is, there are also such= priority information in other place (for example OTN BW sub-TLV in Section 4.1.3 in RFC7138), do we need to re= peat here? What is the relationship if we have two priorities? Is it possib= le the OTN priority is not consistent with flexi-grid priority? Why? And Ho= w to deal with this?

3)      Agreed, will change both the min/max widths to 16-bit in the next versio= n;

4)      Personally I don=A1=AFt think it=A1=AFs necessary to change the current = WG draft: I think your proposed representation can have equivalent result a= s the one in current WG draft;

Hi, Rajan,

 

Firstly sorry for the very late response.

 

For your first concern, I see some difference in = TLVs about priority issue (Table I in your draft). I think I understand you= r description but I didn't find very much advantage to include such 'scalab= le' settings.

 

RR>> Priority= based advertisement is pretty standard mechanism used in all existing RFCs= .  For e.g. you can find these in WSON, OTN  docs and any other T= e-extensions draft.

 

Another concern from me is, for the flexi-grid li= terature, there are more than one WG draft, I think it's better to consider= such case in fwk draft, and after that the OSPF one can revise accordingly= . P.S, I don't know whether this topic was discussed on the list before (perhaps there are some conclusions, let = me know). If not, I would like to suggest move to the list.

 

RR>> I looked= at framework.  Yes, it doesn=A1=AFt talk about priority based adverti= sement.  Thanks for pointing this out. Good catch. We will provide thi= s comment to FWK authors & CC you.  I do not see any issue updating the fwk doc with this detail.   

 

For your second concern on Max LSP Bandwidth, my = understanding is you are trying to use the description in section 3.2 of yo= ur draft to replace the one in section 4.3 of current WG draft. Is this tru= e? I believe the description in your draft is clear and correct. BTW, I noticed bit difference in Min Bandwidth= (16 bits allocated in your draft and 8 bit in current WG draft), hopefully= this will not be a big issue (8 bit support a bandwidth up to 3200GHz, whi= ch is absolutely more than the normal requirement for a minimal BW).

 

RR>>  Ye= s, I was referring to section 3.2 in our draft.   

We went with 16-bit= fields for Min & Max fields as the values for these fields range from = 0 =A8C 384.  We tried to address the case of using full spectrum BW as= one LSP.  This is an extreme case but can=A1=AFt be ruled out.

 

Pl let me know if y= ou have any other comments.

Thanks.

 

Best wishes,

Haomian

Haomian,

 

As I had mentioned we are no longer pushing for S= uperChannel in the draft.  So, this should make it easier to merge the= docs.

 

In my view there are couple of areas your draft d= oesn't address which can be taken from our draft:

 

1.  You have separated Max & Min Slot wi= dth in Port Label restriction sub-TLV.  This is O.K. But this doesn't = allow for priority based Min/Max usage.   Our draft allows for th= is flexibility which can be used.

2.  Max LSP Bandwidth field definition can b= e taken from our doc.

 

The priority handling can be further simplified b= y merging slice info & Min/Max fields in to a single sub-TLV if other a= uthors agree.

 

Pl let me know.

 

Thx

Rajan

Hi, Rajan and Khuzema,

 

Thanks for reminding. Do you guys have any sugges= tion on how to merge? Even if we think the current draft is self-contained,= we are still open on this.

 

I know there are some different ideas from Infine= ra, but sorry I am not fully understand every detail. Please let me know th= e exact section that need to be updated and let's see how to proceed. Again= , this will finally be determined by the WG since already adopted.

Hi, Rajan and all,

 

Thank you for your clarification and I = now fully understand your question. I think you have misunderstood Section = 4.3. of this draft. It was not to describe dynamic Max & Min LSP bandwidth but rather the capability/constraint a= ssociated with an port, which rarely change over time.

 

Isn=A1=AFt information per priority al= ready supported? Quoting text from the drafts referred:

 

=A1=B0The technology specific part of the WSON IS=
CD may include a variable

   number of sub-TL= Vs called Bandwidth sub-TLVs.=A1=B1

 

As for the Mix and Max LSP bandwidth, c= ould you give me an example of what you said below, i.e.,=A1=B0Availability= of  =A1=AEN=A1=AF consecutive labels doesn=A1=AFt mean you can setup an LSP with a size of =A1=AEN=A1=AF=A1=B1?

 

    What does the WG think of the issue under discus= sion?

 

Regards,

Xian

Xian,

&n= bsp;

I under= stand this doc is trying to reuse GEN-EN= CODE & there is support for priority.  I am not referring to this = one.  The Min Width & Max  Width fields do exist in the draft= but these alone are not sufficient. We need info per priority for the following reason.

 

The intent of Min & Max width info is to specify what is the = Minimum/Maximum LSP bandwidth an LSP could reserve at a given priority =A1= =AEp=A1=AF on the link.  You can draw parallel to =A1=AEMinimum LSP Bandwidth=A1=AF & =A1=AEMaximum LSP Bandwidth=A1=AF fields in RFC = 4202.   

 

I don=A1=AFt understand how you can derive this from label set fi= eld.   Availability of  =A1=AEN=A1=AF consecutive labels doe= sn=A1=AFt mean you can setup an LSP with a size of =A1=AEN=A1=AF. 

 

Thx

Rajan

Hi, Rajan,

 

    As I was not involved earlier, I find the foll= owing may be  a bit long for others in the WG to get involved.  B= efore I dive into the discussion and share my thoughts, am I accurate if I recap the question as:

 

   You think the existing = text in draft-ietf-ccamp-flexible-grid-ospf-ext-01 do not support the follo= wing:

1)      Do not support priority;

2)      Do not convey the min & max LSP bandwidth information= in the SCSI field;

 

Could you confirm my interpretation of your issue?

 

The following is my thoughts ( subject to change if the question = I recapped above is not as exact as what you want to say):

 

The  current method is to reuse what has already been propos= ed for WSON. So it reuses the SCSI field defined in WSON-OSPF draft (https://tools.ietf.org/html/draft-ietf-ccamp-wson-sig= nal-compatibility-ospf-15#section-3.1). So, it DOES support priority (see the details are in [GEN-ENCODE] draft-ie= tf-ccamp-general-constraint-encode-20). Exactly because of the same reason,= the draft under discussion uses label set field to describe what frequency= slots are available. So, although it allows for all different varieties supported by [GEN-ENCODE] (i.e., lis= t, bitmap, inclusive, exclusive etc.), the method does not see the need of = specify the max&min LSP bandwidth since it can be naturally deduced fro= m the available frequency spectrum information conveyed.  

 

The above discussion actually reminds me of a question Ramon rais= ed up a while ago among the authors of this draft, what has been defined in= WSON-OSPF is truly usable labels in signaling. But with Flexi-grid, it is not true anymore. For example, although we use = Inclusive Label Range to describe available frequency range, say the exampl= e in Section 4.4 of  draft-ietf-ccamp-flexible-grid-ospf-ext-01 (assum= e m=3D1), none of these labels are directly usable if what is actually requested is a bandwidth with m=3D2.  I my= self do not see any issue as long as we make it clear we use the format jus= t to describe what resource available NOT usable labels. Since it is a WG d= raft, it is worthwhile to solicit what you think?

 

Cheers,
Xian

The pri= ority in each layer is independent.  The intent of explicitly carrying= priority info in the advertisement is to allow for LSP creation at differe= nt priorities.  Note that priority defined in OTN RFC don=A1=AFt apply here as it is a different layer.   Y= ou can have L0-LSP setup at priority-1 but L1-Telink (OTN link) formed out = of this may advertise all 8 or subset of them.  It is an implementatio= n choice.  I don=A1=AFt see any conflicts here.

&n= bsp;

Once we= agree on the following items we can figure out TLV encoding options.<= /o:p>

&n= bsp;

1.      Allow for Advertisement of Min & Max slot widths at different prioriti= es =A8C up to 8

2.      Min/Max slot width field =A8C 16 bit instead of 8  (I see you are agr= eeing to this change below)

3.      Max LSP Bandwidth =A8C this was debated in previous meetings but no firm c= onclusion.

Hi, Rajan,

 

Thanks for the information, I noticed there is a change talking a= bout extending Flexi-grid data plan to satisfy requirements in RFC4202. I f= orward this email to all the authors of OSPF draft to advertise your commentsJ  <= /p>

 

Firstly let=A1=AFs recall the sub-TLV format in draft-dhillon-cca= mp-flexgrid-ospfte-ext as follow:

   +-+-+-+-+-= +-+-+-+-+-+-+-+-+-+-+-+-= 3;-+-+-+-+-+-+-+-+-+-+-+-+-= +-+-+

 

Then I share my understanding on your concern. Compared with sub-= TLV in section 4.3 of draft-ietf-ccamp-flexible-grid-ospf-ext-01, I highlig= ht the difference as follow:

 

In your proposal,

1)      Slice Spacing is preferred to be carried in the  sub= -TLV;

2)      Priority bits are preferred to be included in sub-TLV;

3)      Min/Max Widths should both be 16-bit;

4)      N-start and Num of Slices to represent the spectrum rathe= r than C.F.G and S.W.G;

 

Below please find my comments:

Firstly I believe both of your structure and the current structur= e in WG draft are satisfying the requirement of flexi-grid FWK draft (the i= nfo model in Fig. 17). We only need to deal with some differences in representation format, and some additional i= nformation may be useful.

 

1)      Different slice spacing is applicable but may not be nece= ssary; the spirit to introduce flexible grid is to allow flexibility in spe= ctrum allocation and current WG draft can satisfy the requirement. Not much further advantage for using slice sp= acing;

2)      Priority bits: I agree that it is widely used, I am basic= ally fine to include priority bits in the sub-TLV. My only concern is, ther= e are also such priority information in other place (for example OTN BW sub-TLV in Section 4.1.3 in RFC7138), d= o we need to repeat here? What is the relationship if we have two prioritie= s? Is it possible the OTN priority is not consistent with flexi-grid priori= ty? Why? And How to deal with this?

3)      Agreed, will change both the min/max widths to 16-bit in = the next version;

4)      Personally I don=A1=AFt think it=A1=AFs necessary to chan= ge the current WG draft: I think your proposed representation can have equi= valent result as the one in current WG draft;

 

Rajan, please correct me if there is misunderstanding, also let m= e know if you have other comments.

 

All, please feel free to comments, or we move to the list if nece= ssaryJ

 

Best wishes,

Haomian

Hi, Rajan,=

 

Firstly sorry for the very l= ate response.

 

For your first concern, I se= e some difference in TLVs about priority issue (Table I in your draft). I t= hink I understand your description but I didn't find very much advantage to= include such 'scalable' settings.

&= nbsp;

RR&g= t;> Priority based advertisement is pretty standard mechanism used in al= l existing RFCs.  For e.g. you can find these in WSON, OTN  docs = and any other Te-extensions draft.

 

Another concern from me is, = for the flexi-grid literature, there are more than one WG draft, I think it= 's better to consider such case in fwk draft, and after that the OSPF one c= an revise accordingly. P.S, I don't know whether this topic was discussed on the list before (perhaps there ar= e some conclusions, let me know). If not, I would like to suggest move to t= he list.

 

RR&g= t;> I looked at framework.  Yes, it doesn=A1=AFt talk about priorit= y based advertisement.  Thanks for pointing this out. Good catch. We w= ill provide this comment to FWK authors & CC you.  I do not see any issue updating the fwk doc with this detail.   

 

For your second concern on M= ax LSP Bandwidth, my understanding is you are trying to use the description= in section 3.2 of your draft to replace the one in section 4.3 of current = WG draft. Is this true? I believe the description in your draft is clear and correct. BTW, I noticed bit differe= nce in Min Bandwidth (16 bits allocated in your draft and 8 bit in current = WG draft), hopefully this will not be a big issue (8 bit support a bandwidt= h up to 3200GHz, which is absolutely more than the normal requirement for a minimal BW).

 

RR&g= t;>  Yes, I was referring to section 3.2 in our draft.   =

We w= ent with 16-bit fields for Min & Max fields as the values for these fie= lds range from 0 =A8C 384.  We tried to address the case of using full= spectrum BW as one LSP.  This is an extreme case but can=A1=AFt be ruled out.

 

Pl l= et me know if you have any other comments.

Thanks.

 

Best wishes,

Haomian

Haomian,

 

As I had mentioned we are no= longer pushing for SuperChannel in the draft.  So, this should make i= t easier to merge the docs.

 

In my view there are couple = of areas your draft doesn't address which can be taken from our draft:=

 

1.  You have separated = Max & Min Slot width in Port Label restriction sub-TLV.  This is O= .K. But this doesn't allow for priority based Min/Max usage.   Ou= r draft allows for this flexibility which can be used.

2.  Max LSP Bandwidth f= ield definition can be taken from our doc.

 

The priority handling can be= further simplified by merging slice info & Min/Max fields in to a sing= le sub-TLV if other authors agree.

 

Pl let me know.

 

Thx

Rajan

Section 4.3 is trying = to use port label restrictions sub-TLV with a new restriction type.  T= his is fine.  But how does a path computing node determine if it can u= se the link to setup an LSP with N-slots @ priority =A1=AEp=A1=AF?   For e.g  I don=A1=AFt want to allow priori= ty 7 LSPs to use bandwidth greater than 20 slots on the link but allow for = LSPs with priority 0, 1 & 2.  Where is this info in the TLV?<= /o:p>

 

We had given examples = when we presented our draft in Taipei IETF-82.  Ref slides 8 & 10 = (link below).  We had coverage for advertisement of  Min & Ma= x slot widths per priority. This is meant to align with RFC 4202.  I believe WG doc lacks this and needs to address.

Hi, Raj= an and all,

&n= bsp;

Thank you for your clarification and I now fully under= stand your question. I think you have misunderstood Section 4.3. of this dr= aft. It was not to describe dynamic Max & Min LSP bandwidth but rather the capability/constraint associated wi= th an port, which rarely change over time.

 

Isn=A1=AFt information per priority already supported= ? Quoting text from the drafts referred:

 

=A1=B0The technology specific part of the WSON ISCD may include a vari=
able

   number of sub-TLVs cal= led Bandwidth sub-TLVs.=A1=B1

 

As for the Mix and Max LSP bandwidth, could you give m= e an example of what you said below, i.e.,=A1=B0Availability of  =A1= =AEN=A1=AF consecutive labels doesn=A1=AFt mean you can setup an LSP with a size of =A1=AEN=A1=AF=A1=B1?

 

 &= nbsp;  What does the WG think of the issue under discussion?

 

Regards,

Xian

Xian,

 

I understand this doc = is trying to reuse GEN-ENCODE & ther= e is support for priority.  I am not referring to this one.  The = Min Width & Max  Width fields do exist in the draft but these alon= e are not sufficient. We need info per priority for the following reason.

=  

The i= ntent of Min & Max width info is to specify what is the Minimum/Maximum= LSP bandwidth an LSP could reserve at a given priority =A1=AEp=A1=AF on th= e link.  You can draw parallel to =A1=AEMinimum LSP Bandwidth=A1=AF & =A1=AEMaximum LSP Bandwidth=A1=AF fields in RFC 4202.   

=  

I don= =A1=AFt understand how you can derive this from label set field.  &nbs= p;Availability of  =A1=AEN=A1=AF consecutive labels doesn=A1=AFt mean = you can setup an LSP with a size of =A1=AEN=A1=AF.

Hi, R= ajan,

=  

 = ;   As I was not involved earlier, I find the following may be &n= bsp;a bit long for others in the WG to get involved.  Before I dive in= to the discussion and share my thoughts, am I accurate if I recap the question as:

=  

   You think the existing text in draft-i= etf-ccamp-flexible-grid-ospf-ext-01 do not support the following:

1)      Do not support priority;

2)      Do not convey the min & max LSP bandwidth information in the SCSI fi= eld;

=  

Could= you confirm my interpretation of your issue?

=  

The f= ollowing is my thoughts ( subject to change if the question I recapped abov= e is not as exact as what you want to say):

=  

The&n= bsp; current method is to reuse what has already been proposed for WSON. So= it reuses the SCSI field defined in WSON-OSPF draft (https://tools.ietf.org/html/draft-ietf-ccamp-wson-signal-compatibili= ty-ospf-15#section-3.1). So, it DOES support priority (see the details are in [GEN-ENCODE] draft-ie= tf-ccamp-general-constraint-encode-20). Exactly because of the same reason,= the draft under discussion uses label set field to describe what frequency= slots are available. So, although it allows for all different varieties supported by [GEN-ENCODE] (i.e., lis= t, bitmap, inclusive, exclusive etc.), the method does not see the need of = specify the max&min LSP bandwidth since it can be naturally deduced fro= m the available frequency spectrum information conveyed.  

=  

The a= bove discussion actually reminds me of a question Ramon raised up a while a= go among the authors of this draft, what has been defined in WSON-OSPF is t= ruly usable labels in signaling. But with Flexi-grid, it is not true anymore. For example, although we use Incl= usive Label Range to describe available frequency range, say the example in= Section 4.4 of  draft-ietf-ccamp-flexible-grid-ospf-ext-01 (assume m= =3D1), none of these labels are directly usable if what is actually requested is a bandwidth with m=3D2.  I my= self do not see any issue as long as we make it clear we use the format jus= t to describe what resource available NOT usable labels. Since it is a WG d= raft, it is worthwhile to solicit what you think?

=  

Cheer= s,
Xian

Haomian,

 

The priority in each l= ayer is independent.  The intent of explicitly carrying priority info = in the advertisement is to allow for LSP creation at different priorities.&= nbsp; Note that priority defined in OTN RFC don=A1=AFt apply here as it is a different layer.   You can have L0-LSP set= up at priority-1 but L1-Telink (OTN link) formed out of this may advertise = all 8 or subset of them.  It is an implementation choice.  I don= =A1=AFt see any conflicts here.

 

Once we agree on the f= ollowing items we can figure out TLV encoding options.

 

1. &nbs= p;    Allow for Adve= rtisement of Min & Max slot widths at different priorities =A8C up to 8=

2. &nbs= p;    Min/Max slot w= idth field =A8C 16 bit instead of 8  (I see you are agreeing to this c= hange below)

3. &nbs= p;    Max LSP Bandwi= dth =A8C this was debated in previous meetings but no firm conclusion.

Thank= s for the information, I noticed there is a change talking about extending = Flexi-grid data plan to satisfy requirements in RFC4202. I forward this ema= il to all the authors of OSPF draft to advertise your commentsJ

=  

Then = I share my understanding on your concern. Compared with sub-TLV in section = 4.3 of draft-ietf-ccamp-flexible-grid-ospf-ext-01, I highlight the differen= ce as follow:

=  

In yo= ur proposal,

1)      Slice Spacing is preferred to be carried in the  sub-TLV;

2)      Priority bits are preferred to be included in sub-TLV;=

3)      Min/Max Widths should both be 16-bit;

4)      N-start and Num of Slices to represent the spectrum rather than C.F.G an= d S.W.G;

=  

Below= please find my comments:

First= ly I believe both of your structure and the current structure in WG draft a= re satisfying the requirement of flexi-grid FWK draft (the info model in Fi= g. 17). We only need to deal with some differences in representation format, and some additional information may = be useful.

=  

1)      Different slice spacing is applicable but may not be necessary; the spir= it to introduce flexible grid is to allow flexibility in spectrum allocatio= n and current WG draft can satisfy the requirement. Not much further advantage for using slice spacing; =

2)      Priority bits: I agree that it is widely used, I am basically fine to in= clude priority bits in the sub-TLV. My only concern is, there are also such= priority information in other place (for example OTN BW sub-TLV in Section 4.1.3 in RFC7138), do we need to re= peat here? What is the relationship if we have two priorities? Is it possib= le the OTN priority is not consistent with flexi-grid priority? Why? And Ho= w to deal with this?

3)      Agreed, will change both the min/max widths to 16-bit in the next versio= n;

4)      Personally I don=A1=AFt think it=A1=AFs necessary to change the current = WG draft: I think your proposed representation can have equivalent result a= s the one in current WG draft;

Hi, Rajan,

 

Firstly sorry for the very late response.

 

For your first concern, I see some difference in = TLVs about priority issue (Table I in your draft). I think I understand you= r description but I didn't find very much advantage to include such 'scalab= le' settings.

 

RR>> Priority= based advertisement is pretty standard mechanism used in all existing RFCs= .  For e.g. you can find these in WSON, OTN  docs and any other T= e-extensions draft.

 

Another concern from me is, for the flexi-grid li= terature, there are more than one WG draft, I think it's better to consider= such case in fwk draft, and after that the OSPF one can revise accordingly= . P.S, I don't know whether this topic was discussed on the list before (perhaps there are some conclusions, let = me know). If not, I would like to suggest move to the list.

 

RR>> I looked= at framework.  Yes, it doesn=A1=AFt talk about priority based adverti= sement.  Thanks for pointing this out. Good catch. We will provide thi= s comment to FWK authors & CC you.  I do not see any issue updating the fwk doc with this detail.   

 

For your second concern on Max LSP Bandwidth, my = understanding is you are trying to use the description in section 3.2 of yo= ur draft to replace the one in section 4.3 of current WG draft. Is this tru= e? I believe the description in your draft is clear and correct. BTW, I noticed bit difference in Min Bandwidth= (16 bits allocated in your draft and 8 bit in current WG draft), hopefully= this will not be a big issue (8 bit support a bandwidth up to 3200GHz, whi= ch is absolutely more than the normal requirement for a minimal BW).

 

RR>>  Ye= s, I was referring to section 3.2 in our draft.   

We went with 16-bit= fields for Min & Max fields as the values for these fields range from = 0 =A8C 384.  We tried to address the case of using full spectrum BW as= one LSP.  This is an extreme case but can=A1=AFt be ruled out.

 

Pl let me know if y= ou have any other comments.

Thanks.

 

Best wishes,

Haomian

Haomian,

 

As I had mentioned we are no longer pushing for S= uperChannel in the draft.  So, this should make it easier to merge the= docs.

 

In my view there are couple of areas your draft d= oesn't address which can be taken from our draft:

 

1.  You have separated Max & Min Slot wi= dth in Port Label restriction sub-TLV.  This is O.K. But this doesn't = allow for priority based Min/Max usage.   Our draft allows for th= is flexibility which can be used.

2.  Max LSP Bandwidth field definition can b= e taken from our doc.

 

The priority handling can be further simplified b= y merging slice info & Min/Max fields in to a single sub-TLV if other a= uthors agree.

 

Pl let me know.

 

Thx

Rajan

Hi, Rajan and Khuzema,

 

Thanks for reminding. Do you guys have any sugges= tion on how to merge? Even if we think the current draft is self-contained,= we are still open on this.

 

I know there are some different ideas from Infine= ra, but sorry I am not fully understand every detail. Please let me know th= e exact section that need to be updated and let's see how to proceed. Again= , this will finally be determined by the WG since already adopted.

 

Thanks.

 

Best wishes,

Haomian

Haomian,

 

We had sent couple of emails asking about merging= the contents with our draft.  Do you see an opportunity or any issues= with the merge?  Can you pl respond on how you would like to proceed?= Pl see the attached email we had sent a while back.

 

 

Thanks
