Hi Salvatore et al:

At IETF 80 in Prague we said "work item, Flow Selection, is under
review, and will be discussed further on the IPFIX list."

Shortly after that (30 March) Brian Trammell posted a review,
pointing out that the draft as it stands doesn't adequately
address what our charter said it would.

I trust that the authors are working on this, can you estimate
when you expect to publish a new revision, please?

[I'll remind you that this is the last remaining item on our
current charter ...]

Cheers, Nevil

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IP Flow Information Export Working Group of the IETF.


	Title           : Export of Structured Data in IPFIX
	Author(s)       : B. Claise, et al.
	Filename        : draft-ietf-ipfix-structured-data-06.txt
	Pages           : 75
	Date            : 2011-05-03

This document specifies an extension to the IP Flow Information 

  eXport (IPFIX) protocol specification in [RFC5101] and the IPFIX 

  information model specified in [RFC5102] to support hierarchical 

  structured data and lists (sequences) of Information Elements in 

  data records.  This extension allows definition of complex data 

  structures such as variable-length lists and specification of 

  hierarchical containment relationships between Templates. 

  Finally, the semantics are provided in order to express the 

  relationship among multiple list elements in a structured data 

  record.

A URL for this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-ietf-ipfix-structured-data-06.txt

Internet-Drafts are also available by anonymous FTP at:
ftp://ftp.ietf.org/internet-drafts/

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the

Hi all:

Sorry if you get multiple copies of this.

The Internet Research Task Force (IRTF) are offering a prize,
as per the notice below ...

Cheers, Nevil

                   CALL FOR NOMINATIONS:

          APPLIED NETWORKING RESEARCH PRIZE (ANRP)


*** Apply until May 8, 2011 for the ANR Prize for IETF-81,
*** July 24-29, 2011 in Quebec City, Canada!

The Applied Networking Research Prize (ANRP) is awarded for
recent results in applied networking research that are relevant
for transitioning into shipping Internet products and related
standardization efforts. Researchers with relevant, recently
published results are encouraged to apply for this prize, which
will offer them the opportunity to present and discuss their work
with the engineers, network operators, policy makers and
scientists that participate in the Internet Engineering Task
Force (IETF) and its research arm, the Internet Research Task
Force (IRTF). Third-party nominations for this prize are also
encouraged. The goal of the Applied Networking Research Prize
(ANRP) is to recognize the best new ideas in networking, and
bring them to the IETF and IRTF especially in cases where they
would not otherwise see much exposure or discussion.

The Applied Networking Research Prize (ANRP) consists of:

  * cash prize of $500 (USD)

  * invited talk at the IRTF Open Meeting

  * travel grant to attend the week-long IETF meeting
    (airfare, hotel, registration, stipend)

  * recognition at the IETF plenary

  * invitation to related social activities

  * potential for additional travel grants to future IETF
    meetings, based on community feedback

The Applied Networking Research Prize (ANRP) will be awarded
three times per year, in conjunction with the three annual IETF
meetings.


HOW TO APPLY

Applicants must nominate a peer-reviewed, recently-published,
original journal, conference or workshop paper. Both self
nominations (nominating one's own paper) and third-party
nominations (nominating someone else's paper) are encouraged. The
nominee must be one of the main authors of the nominated paper.

The nominated paper should provide a scientific foundation for
possible future IETF engineering work or IRTF experimentation,
analyze the behavior of Internet protocols in operational
deployments or realistic testbeds, make an important contribution
to the understanding of Internet scalability, performance,
reliability, security or capability, or otherwise be of relevance
to ongoing or future IETF or IRTF activities.

Applicants must briefly describe how the nominated paper relates
to these goals, and are encouraged to describe how presentation
of these research results will foster their transition into new
IETF engineering or IRTF experimentation, or otherwise seed new
activities that will have an impact on the real-world Internet.

The goal of the Applied Networking Research Prize (ANRP) is to
foster the transitioning of research results into real-world
benefits for the Internet. Therefore, applicants must indicate
that they (or the nominee, in case of third-party applications)
are available to attend the respective IETF meeting in person and
in its entirety.

Applications must include:

  * the name and email address of the nominee

  * a reference to the published nominated paper

  * a PDF copy of the nominated paper

  * a statement that describes how the nominated paper
    fulfills the goals of the award

  * a statement that the nominee is available to attend the
    respective IETF meeting in person and in its entirety

  * a brief biography or CV of the nominee

  * optionally, any other supporting information (link to
    nominee's web site, etc.)

*** Applications are submitted by email to anrp@isoc.org. ***


SELECTION PROCESS

A small selection committee comprised of individuals
knowledgeable about the IRTF, IETF and the broader networking
research community will evaluate the submissions against these
selection criteria. The goal is to select 1-2 submissions for the
Applied Networking Research Prize (ANRP) during each application
period. All applicants will be notified by email.

Document:  draft-ietf-ipfix-psamp-mib-03
Title:     Definitions of Managed Objects for Packet Sampling
Editors:   Thomas Dietz, Benoit Claise. Juergen Quittek
Intended status:  Standards Track

As required by RFC-to-be draft-ietf-proto-wgchair-doc-shepherding,
this is the current template for the Document Shepherd Write-Up. 
Changes are expected over time. This version is dated September 17, 2008.

(1.a) Who is the Document Shepherd for this document? Has the 
      Document Shepherd personally reviewed this version of the 
      document and, in particular, does he or she believe this 
      version is ready for forwarding to the IESG for publication?

  Nevil Brownlee.  I have reviewed this draft, I believe it's ready
  for publication.

(1.b) Has the document had adequate review both from key WG members 
      and from key non-WG members? Does the Document Shepherd have 
      any concerns about the depth or breadth of the reviews that 
      have been performed?

  Yes.  Version 00 appeared in March 2010, Version 03 (March 2011)
  makes changes suggested during WGLC.

(1.c) Does the Document Shepherd have concerns that the document 
      needs more review from a particular or broader perspective, 
      e.g., security, operational complexity, someone familiar with 
      AAA, internationalization or XML?

  I believe that MIB Doctors were consulted for help with finding
  a textual convention for float64 objects (used in the current
  version).  However, a final check by MIB Doctors would be helpful.
  Apart from that, this is a small extension to the IPFIX MIB.

(1.d) Does the Document Shepherd have any specific concerns or 
      issues with this document that the Responsible Area Director 
      and/or the IESG should be aware of? For example, perhaps he 
      or she is uncomfortable with certain parts of the document, or 
      has concerns whether there really is a need for it. In any 
      event, if the WG has discussed those issues and has indicated 
      that it still wishes to advance the document, detail those 
      concerns here. Has an IPR disclosure related to this document 
      been filed? If so, please include a reference to the 
      disclosure and summarize the WG discussion and conclusion on 
      this issue.

  There are no such issues with this draft.

(1.e) How solid is the WG consensus behind this document? Does it 
      represent the strong concurrence of a few individuals, with 
      others being silent, or does the WG as a whole understand and 
      agree with it?

  The WG has reached full consensus on this draft.

(1.f) Has anyone threatened an appeal or otherwise indicated extreme 
      discontent? If so, please summarise the areas of conflict in 
      separate email messages to the Responsible Area Director. (It 
      should be in a separate email because this questionnaire is 
      entered into the ID Tracker.)

  No.

(1.g) Has the Document Shepherd personally verified that the 
      document satisfies all ID nits? (See 
      http://www.ietf.org/ID-Checklist.html and 
      http://tools.ietf.org/tools/idnits/). Boilerplate checks are 
      not enough; this check needs to be thorough. Has the document 
      met all formal review criteria it needs to, such as the MIB 
      Doctor, media type and URI type reviews?

  Yes.  Apart from one outdated reference, there are no ID nits.

(1.h) Has the document split its references into normative and 
      informative? Are there normative references to documents that 
      are not ready for advancement or are otherwise in an unclear 
      state? If such normative references exist, what is the 
      strategy for their completion? Are there normative references 
      that are downward references, as described in [RFC3967]? If 
      so, list these downward references to support the Area 
      Director in the Last Call procedure for them [RFC3967].

  There is one normative reference to an I-D:
  draft-ietf-opsawg-mib-floats-01 (this is the reference mentioned 
  in 1.g above).  This draft contains the textual convention 
  this MIB uses for float64; any document using float objects
  needs this convention!

(1.i) Has the Document Shepherd verified that the document IANA 
      consideration section exists and is consistent with the body 
      of the document? If the document specifies protocol 
      extensions, are reservations requested in appropriate IANA 
      registries? Are the IANA registries clearly identified? If 
      the document creates a new registry, does it define the 
      proposed initial contents of the registry and an allocation 
      procedure for future registrations? Does it suggest a 
      reasonable name for the new registry? See [RFC5226]. If the 
      document describes an Expert Review process has Shepherd 
      conferred with the Responsible Area Director so that the IESG 
      can appoint the needed Expert during the IESG Evaluation?

  Yes.  The IANA requirements are clearly explained.

(1.j) Has the Document Shepherd verified that sections of the 
      document that are written in a formal language, such as XML 
      code, BNF rules, MIB definitions, etc., validate correctly in 
      an automated checker?

  Yes.  Using http://www.agentpp.com/mibtools/mibtools.html,
  the only things that raise warnings relate to to-be-assigned
  numbers and to Float64TC objects.

(1.k) The IESG approval announcement includes a Document 
      Announcement Write-Up. Please provide such a Document 
      Announcement Write-Up? Recent examples can be found in the
      "Action" announcements for approved documents. The approval 
      announcement contains the following sections:

         Technical Summary 
   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it describes extensions to the IPFIX MIB module
   [RFC5815].  For IPFIX implementations that use packet Sampling
   (PSAMP) techniques as described in [RFC5475], this memo defines the
   PSAMP MIB module containing managed objects for providing information
   on applied packet selection functions and their parameters.

         Working Group Summary 
             Was there anything in WG process that is worth noting? For 
             example, was there controversy about particular points or 
             were there decisions where the consensus was particularly 
             rough?
   This document was originally intended to be a stand-alone MIB;
   once the WG had decided to produce an IPFIX MIB, PSAMP was left
   to be added as an extension to the IPFIX MIB.
   No controversy arose during the work on this MIB.

         Document Quality
   As well as its WGLC, this MIB was reviewed by Christian Henke and 
   Benoit Claise.  No issues were found.

	Title           : Export of Structured Data in IPFIX
	Author(s)       : B. Claise, et al.
	Filename        : draft-ietf-ipfix-structured-data-06.txt

	Date            : 2011-05-03

This document specifies an extension to the IP Flow Information 

  eXport (IPFIX) protocol specification in [RFC5101] and the IPFIX 

  information model specified in [RFC5102] to support hierarchical 

  structured data and lists (sequences) of Information Elements in 

  data records.  This extension allows definition of complex data 

  structures such as variable-length lists and specification of 

  hierarchical containment relationships between Templates. 

  Finally, the semantics are provided in order to express the 

  relationship among multiple list elements in a structured data 

  record.

Technical Summary

        This document specifies an extension to the IP Flow Information 
        eXport (IPFIX) protocol specification in [RFC5101] and the IPFIX 
        information model specified in [RFC5102] to support hierarchical 
        structured data and lists (sequences) of Information Elements in 
        data records.  This extension allows definition of complex data 
        structures such as variable-length lists and specification of 
        hierarchical containment relationships between Templates. 
        Finally, the semantics are provided in order to express the 
        relationship among multiple list elements in a structured data 
        record. 

Working Group Summary

  Work on this draft began in March 2009.  Its development has had
  strong co-operative work from WG members in Europe, Japan and 
  elsewhere.  Its WG Last Call generated enough comments that a
  second WGLC was run and this version represents  the WG 
  consensus. 

Document Quality

  The shepherd is not aware of any current implementations, 
  but the list discussion makes him think that they do exist.
 
Personnel

   Nevil Brownlee is Document Shepherd for this document.
   Dan Romascanu is the Responsible Area Director.

Hi Dan, all,

here are the xml sources. I think the RFC Editors might need them to publish
the draft as RFC.

Best Regards,

Thomas

      <t>All tables in this MIB module may be considered sensitive or=0A=
      vulnerable in some network environments because objects in the =

these=0A=

responsibility to=0A=

This document describes anonymization techniques for IP flow data and
the export of anonymized data using the IP Flow Information Export
(IPFIX) protocol.  It categorizes common anonymization schemes and
defines the parameters needed to describe them.  It provides
guidelines for the implementation of anonymized data export and
storage over IPFIX, and describes an information model and Options-
based method for anonymization metadata export within the IPFIX
protocol or storage in IPFIX Files.  This document defines an 
Experimental Protocol for the Internet community.

This document is a product of the IP Flow Information Export Working Group of the IETF.


EXPERIMENTAL: This memo defines an Experimental Protocol for the
Internet community.  It does not specify an Internet standard of any
kind. Discussion and suggestions for improvement are requested.
Distribution of this memo is unlimited.

   (1.a)  Who is the Document Shepherd for this document?  Has the
          Document Shepherd personally reviewed this version of the
          document and, in particular, does he or she believe this
          version is ready for forwarding to the IESG for publication?

Juergen Quittek is the document shepherd. He has reviewed it personally
and believes that this version is ready for forwarding to the IESG
for publication.

   (1.b)  Has the document had adequate review both from key WG members
          and from key non-WG members?  Does the Document Shepherd have
          any concerns about the depth or breadth of the reviews that
          have been performed?

The document had multiple individual reviews from key WG members during
WG last call. Since it contains a YANG module, a YANG doctor review was
organized for this draft by the NETMOD WG. Several comments were made and
have been addressed when updating the document after the reviews.The
shepherd has no concern about the depth or breadth of the reviews.

   (1.c)  Does the Document Shepherd have concerns that the document
          needs more review from a particular or broader perspective,
          e.g., security, operational complexity, someone familiar with
          AAA, internationalization, or XML?

The document shepherd sees no need for an additional particular review.

   (1.d)  Does the Document Shepherd have any specific concerns or
          issues with this document that the Responsible Area Director
          and/or the IESG should be aware of?  For example, perhaps he
          or she is uncomfortable with certain parts of the document, or
          has concerns whether there really is a need for it.  In any
          event, if the WG has discussed those issues and has indicated
          that it still wishes to advance the document, detail those
          concerns here.  Has an IPR disclosure related to this document
          been filed?  If so, please include a reference to the
          disclosure and summarize the WG discussion and conclusion on
          this issue.

There is no such concern.

   (1.e)  How solid is the WG consensus behind this document?  Does it
          represent the strong concurrence of a few individuals, with
          others being silent, or does the WG as a whole understand and
          agree with it?

There is a strong consensus in the IPFIX WG to publish this version
of the document. There are no particular issues in the document
without strong consensus in the IPFIX WG.

   (1.f)  Has anyone threatened an appeal or otherwise indicated extreme
          discontent?  If so, please summarize the areas of conflict in
          separate email messages to the Responsible Area Director.  (It
          should be in a separate email because this questionnaire is
          entered into the ID Tracker.)

There was no appeal.

   (1.g)  Has the Document Shepherd personally verified that the
          document satisfies all ID nits?  (See
          http://www.ietf.org/ID-Checklist.html and
          http://tools.ietf.org/tools/idnits/.)  Boilerplate checks are
          not enough; this check needs to be thorough.  Has the document
          met all formal review criteria it needs to, such as the MIB
          Doctor, media type, and URI type reviews?  If the document
          does not already indicate its intended status at the top of
          the first page, please indicate the intended status here.

The document shepherd checked for ID nits.  There are none.

   (1.h)  Has the document split its references into normative and
          informative?  Are there normative references to documents that
          are not ready for advancement or are otherwise in an unclear
          state?  If such normative references exist, what is the
          strategy for their completion?  Are there normative references
          that are downward references, as described in [RFC3967]?  If
          so, list these downward references to support the Area
          Director in the Last Call procedure for them [RFC3967].

References are arranged correctly.

   (1.i)  Has the Document Shepherd verified that the document's IANA
          Considerations section exists and is consistent with the body
          of the document?  If the document specifies protocol
          extensions, are reservations requested in appropriate IANA
          registries?  Are the IANA registries clearly identified?  If
          the document creates a new registry, does it define the
          proposed initial contents of the registry and an allocation
          procedure for future registrations?  Does it suggest a
          reasonable name for the new registry?  See [RFC2434].  If the
          document describes an Expert Review process, has the Document
          Shepherd conferred with the Responsible Area Director so that
          the IESG can appoint the needed Expert during IESG Evaluation?

The document defines actions for IANA in an appropriate way.

   (1.j)  Has the Document Shepherd verified that sections of the
          document that are written in a formal language, such as XML
          code, BNF rules, MIB definitions, etc., validate correctly in
          an automated checker?

The document contains a YANG module in section 6 and several XML
configuration modules in section 7. All have been validated.

   (1.k)  The IESG approval announcement includes a Document
          Announcement Write-Up.  Please provide such a Document
          Announcement Write-Up.  Recent examples can be found in the
          "Action" announcements for approved documents.  The approval
          announcement contains the following sections:

Technical Summary

   This document specifies a data model for configuring and monitoring
   Selection Processes, Caches, Exporting Processes, and Collecting
   Processes of IPFIX and PSAMP compliant Monitoring Devices using the
   NETCONF protocol [RFC4741].  The data model is defined using UML
   (Unified Modeling Language) class diagrams and formally specified
   using YANG [RFC6020].  The configuration data is encoded in
   Extensible Markup Language (XML).

Working Group Summary

   The mediation framework was added to the IPIFX charter in 2008.
   The document was discussed at all meetings since then and had
   several revisions. There was nothing special about this document.

Document Quality

   The document underwent a WG last call in the IPFIX WG and a YANG
   doctor review organized by the NETMOG WG. This way, a high document
   quality has been achieved already.

Personnel

   Juergen Quittek is shepherding this document. Dan Romascanu is the
   responsible Area director.

   Flow selection is the process of selecting a subset of flows from all
   flows observed at an observation point.  Flow selection reduces the
   effort of post-processing flow data and transferring flow records.
   This document describes motivations for flow selection and presents
   flow selection techniques.  It provides an information model for
   configuring flow selection techniques and discusses what information
   about a flow selection process should be exported.

Hi all,

we worked on a major revision of the flow selection draft and just =
submitted a new version (see below). Among other changes we now provide =
a much improved classification of methods, which is more consistent with =
the PSAMP packet selection documents.=20
Many thanks to all who provided comments.=20

Changes:
 - Flow recording process removed
 - Clarification of difference between flow selection and packet =
selection
 - Distinguished flow filtering and flow sampling similar to PSAMP
 - Flow selection in the metering process either before aggregation or =
after aggregation
 - Integrated Flow-state dependent packet selection
 - Supporting arbitrary  key space subsets with property match flow =
filtering
 - Removed timestamp IEs for reporting=20
 - Mediator integrated in first picture
 - Configuration parameters and IEs redefined and re-named
 - Many rewording, shortened several paragraphs to improve readability

Kind regards
Tanja

Hi all:

Thanks very much to all the authors of the flow-selection draft,
it does indeed look much better.  Since there's so much new material
in it, we need to run a new WG LC on it - that start's today, and
will finish on Friday, 10 June.  Do please read it anew, and send
comments to the list.  Brief comments such as "yes, this looks fine
now" are welcome, of course!

Cheers, Nevil

Hi, Nevil, all,

The following is intended as a WGLC comment on flow-selection-tech. It =
will not be my only one; however, it identifies an issue I've seen in a =
cursory review of the document which I believe could benefit from some =
discussion:

Is this document intended to update RFC 5470? I'm not convinced this is =
necessary; e.g. RFC 6235 defines a flow-modifying intermediate process, =
and shows how it could be integrated into various stages within the =
IPFIX Architecture, without introducing a new model of how data is =
handled in the architecture. If each additional intermediate process =
definition updates the architecture, the architecture becomes confusing, =
and subsequently useless.

If the authors and the WG believe it is necessary to update 5470 to =
support flow selection, I would _strongly_ suggest reviewing all new =
terminology, as the proposed terms collide with existing terms of art in =
network measurement. Specifically, there are two serious problems here. =
First, I'm not aware of any use of the word "classification" with =
respect to the associating of packets with flows; classification instead =
seems primarily to be used when associating a label with a packet of a =
flow (e.g., application classification). Second, while packets are =
indeed aggregated into flows, the word "aggregation" in this draft is =
used in a completely different way than in either -ipfix-a9n or in RFCs =
5982 or 6183. This could lead to confusion.

More detailed comments to follow.

Best regards,

Brian

Dear Tanja,

One quick remark (a thorough review should follow) regarding this I.E.

7.5.  fsFlowEntryTotalCount

    Description:

       This Information Element specifies the current number of all Flow
       Entries that form the parent population as input to the Flow
       Selection Process.

    Abstract Data Type: unsigned64

    ElementId: TBD5

    Status: Proposed

    Units: Flow Entries


In Cisco, years ago, we have defined the I.E. #3 with the same concept. 
It is used when we do router-based aggregation, which is exported with 
NetFlow version 8. It represents the number of flow that we're given as 
input to the router-based aggregation process.
See 
http://www.cisco.com/en/US/technologies/tk648/tk362/technologies_white_paper09186a00800a3db9_ps6601_Products_White_Paper.html 
(which btw, we're busy updating)

So this TBD5 should be 3.  Does it make sense?

Regards, Benoit.

Hi, Benoit,

I disagree, I think, for two reasons.

First, if IE3 is defined with parallel semantics to IE1 and IE2 (octet =
and packet delta count), it should provide _delta_ count, not _total_ =
count, semantics (i.e., subsequent exports are a delta from last export, =
not a replacement value).

Second, this is an IE with a much more restricted semantic meaning; it =
refers to Flow Entries (a new bit of flow selection terminology, the =
difference between which and "Flow" and "Flow Record" is still a bit =
unclear to me) that are given as _input_ to a (undefined but I presume =
contextually resolvable) Flow Selection Process.=20

This is somewhat different than the Flow analog of Packet and Octet =
Delta Count.

(However, if IE3 was _not_ defined by Cisco with this in mind, and =
really means "the total number of flows seen at the (Metering Process or =
analogue) _before_ flow processing", objection withdrawn.)

Best regards,

Brian

Brian,

The flow count in field #3 follows the same semantics as the octet count 
in field #1 and the packet count in field #2.

We use it internally in our "top talkers" feature to count the number of 
aggregated flows, though we don't currently export it.

As to the terminology issue: a "flow" is the set of packets which are 
observed at the input to the metering process, while a "flow record" is 
the output from the metering process. I look forward to finding out what 
"Flow Entries" are :-)

P.

See RFC5101

  Metering Process

       The Metering Process generates Flow Records.  Inputs to the
       process are packet headers and characteristics observed at an
       Observation Point, and packet treatment at the Observation Point
       (for example, the selected output interface).

Considering that there are no flows as input to the Metering Process, ...

	"the total number of flows seen at the (Metering Process or analogue) _before_ flow processing"

That gives

	"the total number of flows seen at the Flow Selection Process before flow processing"

Which is equivalent to

Description:

      This Information Element specifies the current number of all Flow
      Entries that form the parent population as input to the Flow
      Selection Process.


And yes, this is how we used this I.E. in Cisco. See Figure D, RFC 6183

(**) this is where value is metered.

Btw, Tanja, this is one of my important WG-LAST points.
http://tools.ietf.org/html/draft-ietf-ipfix-flow-selection-tech-06, 
Figure 1, should build on the top of the RFC6183, and clearly explains 
where is the Flow Intermediate Process.

Hi, all,

The following are the balance of my WGLC comments on the flow selection =
draft.

Summary: The document has made _significant_ progress in the right =
direction, in my opinion, but requires at least one more revision before =
it is ready for the IESG. The issues are as follows:

1. As Benoit said, and in refinement of my earlier message, the model =
which the document uses should be based on an Intermediate (Flow) =
Selection Process (IFSP) as in RFC 6183, instead of adding new concepts =
to 5470. The case in section 4.1 is a bit of a special one, to address =
an uncommon requirement; in addition, it isn't really a flow selection =
process at all, but rather a packet selection process that selects =
packets on the same criteria that by which packets are separated into =
flows by the flow key. Therefore it can be noted here, I think, that the =
_function_ run within an IFSP can run _as a packet selection process_ =
before flow generation within an MP without having to hack new processes =
into the 5470 model. Section 6 will have to be updated a bit to fit this =
change as well.

2. The document should use a different term for "aggregation" (of =
packets into flows) to avoid collision with terminology related to =
aggregation in RFCs 5982 and 6183.

3. The document should use a different term for "classification" to =
avoid confusion with the use of this term with respect to "flow =
classification" and labeling. I realize 5470 uses the verb "classify" to =
refer to this process; I really wish it didn't.=20

Aggregation and classification _together_ comprise the "assignment" of =
packets to flows, and flow "generation". I'm afraid I don't have any =
better suggestions at this time.

4. Terminology based on terminology borrowed by analogy or reference to =
the packet selection techniques draft is a good idea; however, these =
terms should be defined in section . Additionally, terminology through =
the entire document should be reviewed for proper capitalization.

5. Within section 6, it is not clear how to apply this configuration =
data model. Should this be harmonized with ipfix-configuration-model?

6. In section 7, I would suggest unifying Paul and Benoit's comments on =
the subject of fsFlowRecordTotalCount; additionally, the IE should be =
named flowDeltaCount to keep parallel with IEs 1 and 2. Consider =
renaming the IEs in general to drop the "fs" prefix. perhaps =
"postSelection" or something similar (as with the pre/post IEs). Review =
other IEs to ensure they are not covered by existing IEs (especially =
those "pre-selection", as with IE 3)

7. What is a Flow Entry? Should this be defined in this document, or =
referenced as terminology from another? If this is what I think it is =
(reporting flow cache size inline), I'm not certain it belongs here in =
flow selection (perhaps in a document on metering process monitoring?).

Best regards,

Brian

seems primarily to be used when associating a label with a packet of a =

5982 or 6183. This could lead to confusion.

A mediator may receive packets containing flow records from other exporters.

The number of flows contained in those those packets counts as a "packet 
characteristic" per the RFC 5101 definition above.

If the mediator wanted to report the number of bytes, packets, and flows 
which it observed, I'd expect it to use fields #1, #2 and #3.

BMWG,
CC: IPFIX WG,

This message begins the second WG Last call on the draft:

IP Flow Information Accounting and Export Benchmarking Methodology
draft-ietf-bmwg-ipflow-meth-01.txt

A URL for this draft is:
http://tools.ietf.org/html/draft-ietf-bmwg-ipflow-meth-01

The Last Call will end on June 20, 2011.

We have discussed this draft in the working group for
over two years and made many improvements.
We have also benefited from review by folks from IPFIX WG.

I now ask everyone to consider items where they commented earlier,
and make sure that the resolutions are satisfactory.

Please weigh-in on whether or not this Internet-Draft
should be given to the Area Directors and IESG for consideration and
publication as an Informational RFC.  Send your comments
to this list and/or acmorton@att.com.

Al
bmwg chair
