Adoption of traffic management draft

Sarah: I support the adoption of draft-constantine-bmwg-traffic-
management as a chartered work item.  With the need for services that
purport to switch data-centers or server farms or VPNs depending on
traffic patterns, a draft such as this could provide some
repeatability to better understand traffic management.

Thanks,

Publication Request and Shepherding Form for IMIX draft

BMWG,

Following Joel's WG consensus call, Lucien Avramov volunteered to 
be the document shepherd for the IMIX draft, and he completed the
shepherd's form (attached). The IETF Last Call started last Monday,
and is still in progress.

Usually I send these forms to the WG, and that step
was delayed about a week, but here it is now.

In the future, Sarah and I will ask for other volunteers to 
learn more about the IETF process through the role of shepherd,
and the shepherd role will be expanding a bit, too.  For now,
I thank Lucien for his willingness to serve the BMWG in this
capacity (your work as shepherd is just beginning, Lucien!).

regards,
Al

This is a Publication Request & document shepherding form for 
   
IMIX Genome: Specification of variable packet sizes for additional testing
draft-ietf-bmwg-imix-genome-04

using the shepherding form dated 24 February 2012, now available from
http://www.ietf.org/iesg/template/doc-writeup.html


(1) What type of RFC is being requested (BCP, Proposed Standard, Internet Standard, Informational,
Experimental, or Historic)? Why is this the proper type of RFC? Is this type of RFC indicated in the title
page header?

Informational, as indicated on the title page.
All BMWG RFCs are traditionally Informational,
in part because they do not define protocols and
the traditional conditions for Stds track advancement
did not apply.  However, they are specifications and
the RFC 2119 terms are applicable to identify the
level of requirements.

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

Technical Summary:

   Benchmarking Methodologies have always relied on test conditions with
   constant packet sizes, with the goal of understanding what network
   device capability has been tested.  Tests with constant packet size
   reveal device capabilities but differ significantly from the
   conditions encountered in operational deployment, and so additional
   tests are sometimes conducted with a mixture of packet sizes, or
   "IMIX".  The mixture of sizes a networking device will encounter is
   highly variable and depends on many factors.  An IMIX suited for one
   networking device and deployment will not be appropriate for another.
   However, the mix of sizes may be known and the tester may be asked to
   augment the fixed size tests.  To address this need, and the
   perpetual goal of specifying repeatable test conditions, this draft
   defines a way to specify the exact repeating sequence of packet sizes
   from the usual set of fixed sizes, and other forms of mixed size
   specification.

Working Group Summary:

WG Consensus was smooth after development over a reasonable period of time.

Document Quality:

There are many implementations of various test equipment that use IMIX. 

Personnel:

Who is the Document Shepherd?  Lucien Avramov
Who is the Responsible Area Director?  Joel Jaeggli 


(3) Briefly describe the review of this document that was performed by the Document Shepherd. If this
version of the document is not ready for publication, please explain why the document is being forwarded
to the IESG.

In depth review of the draft and the meeting minutes from the IETF conferences regarding this draft.

(4) Does the document Shepherd have any concerns about the depth or breadth of the reviews that have been performed?

No concerns

(5) Do portions of the document need review from a particular or from broader perspective, e.g., security,
operational complexity, AAA, DNS, DHCP, XML, or internationalization? If so, describe the review that
took place.

No

(6) Describe any specific concerns or issues that the Document Shepherd has with this document that the
Responsible Area Director and/or the IESG should be aware of? For example, perhaps he or she is
uncomfortable with certain parts of the document, or has concerns whether there really is a need for it. In
any event, if the WG has discussed those issues and has indicated that it still wishes to advance the
document, detail those concerns here.

No concerns

(7) Has each author confirmed that any and all appropriate IPR disclosures required for full conformance
with the provisions of BCP 78 and BCP 79 have already been filed. If not, explain why?

Yes.

(8) Has an IPR disclosure been filed that references this document? If so, summarize any WG discussion and
conclusion regarding the IPR disclosures.

No

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

Long standing reviews were constructive and agreeable, consensus is strong.

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

No

(11) Identify any ID nits the Document Shepherd has found in this document. (See
http://www.ietf.org/tools/idnits/ and the Internet-Drafts Checklist). Boilerplate checks are not
enough; this check needs to be thorough.

Based on idnits 2.12.16  <at>  April 13, 2013
Summary: 0 errors (**), 0 flaws (~~), 1 warning (==), 1 comment (--).
where the warning and comment stem from the document date, 12/12/12.

(12) Describe how the document meets any required formal review criteria, such as the MIB Doctor, media
type, and URI type reviews.

N/A

(13) Have all references within this document been identified as either normative or informative?

Yes

(14) Are there normative references to documents that are not ready for advancement or are otherwise in an
unclear state? If such normative references exist, what is the plan for their completion?

No

(15) Are there downward normative references references (see RFC 3967)? If so, list these downward
references to support the Area Director in the Last Call procedure.

No

(16) Will publication of this document change the status of any existing RFCs? Are those RFCs listed on the
title page header, listed in the abstract, and discussed in the introduction? If the RFCs are not listed in
the Abstract and Introduction, explain why, and point to the part of the document where the relationship
of this document to the other RFCs is discussed. If this information is not in the document, explain why the
WG considers it unnecessary.

No

(17) Describe the Document Shepherd's review of the IANA considerations section, especially with regard
to its consistency with the body of the document. Confirm that all protocol extensions that the document
makes are associated with the appropriate reservations in IANA registries. Confirm that any referenced
IANA registries have been clearly identified. Confirm that newly created IANA registries include a
detailed specification of the initial contents for the registry, that allocations procedures for
future registrations are defined, and a reasonable name for the new registry has been suggested (see RFC 5226).

N/A, no IANA considerations.

(18) List any new IANA registries that require Expert Review for future allocations. Provide any public
guidance that the IESG would find useful in selecting the IANA Experts for these new registries.

N/A

(19) Describe reviews and automated checks performed by the Document Shepherd to validate sections of the
document written in a formal language, such as XML code, BNF rules, MIB definitions, etc.

None.

Biggest Fake Conference in Computer Science

Biggest Fake Conference in Computer Science

We are researchers from different parts of the world and conducted a study on  
the world’s biggest bogus computer science conference WORLDCOMP 
( http://sites.google.com/site/worlddump1 ) organized by Prof. Hamid Arabnia 
from University of Georgia, USA.

We submitted a fake paper to WORLDCOMP 2011 and again (the same paper 
with a modified title) to WORLDCOMP 2012. This paper had numerous 
fundamental mistakes. Sample statements from that paper include: 

(1). Binary logic is fuzzy logic and vice versa
(2). Pascal developed fuzzy logic
(3). Object oriented languages do not exhibit any polymorphism or inheritance
(4). TCP and IP are synonyms and are part of OSI model 
(5). Distributed systems deal with only one computer
(6). Laptop is an example for a super computer
(7). Operating system is an example for computer hardware

Also, our paper did not express any conceptual meaning.  However, it 
was accepted both the times without any modifications (and without 
any reviews) and we were invited to submit the final paper and a 
payment of $500+ fee to present the paper. We decided to use the 
fee for better purposes than making Prof. Hamid Arabnia (Chairman 
of WORLDCOMP) rich. After that, we received few reminders from 
WORLDCOMP to pay the fee but we never responded. 

We MUST say that you should look at the above website if you have any thoughts 
to submit a paper to WORLDCOMP.  DBLP and other indexing agencies have stopped 
indexing WORLDCOMP’s proceedings since 2011 due to its fakeness. See 
http://www.informatik.uni-trier.de/~ley/db/conf/icai/index.html for of one of the 
conferences of WORLDCOMP and notice that there is no listing after 2010. See Section 2 of
http://sites.google.com/site/dumpconf for comments from well-known researchers 
about WORLDCOMP. 

The status of your WORLDCOMP papers can be changed from scientific
to other (i.e., junk or non-technical) at any time. Better not to have a paper than 
having it in WORLDCOMP and spoil the resume and peace of mind forever!

Our study revealed that WORLDCOMP is a money making business, 
using University of Georgia mask, for Prof. Hamid Arabnia. He is throwing 
out a small chunk of that money (around 20 dollars per paper published 
in WORLDCOMP’s proceedings) to his puppet (Mr. Ashu Solo or A.M.G. Solo) 
who publicizes WORLDCOMP and also defends it at various forums, using 
fake/anonymous names. The puppet uses fake names and defames other conferences
to divert traffic to WORLDCOMP. He also makes anonymous phone calls and tries to 
threaten the critiques of WORLDCOMP (See Item 7 of Section 5 of above website). 
That is, the puppet does all his best to get a maximum number of papers published 
at WORLDCOMP to get more money into his (and Prof. Hamid Arabnia’s) pockets. 

Monte Carlo Resort (the venue of WORLDCOMP for more than 10 years, until 2012) has 
refused to provide the venue for WORLDCOMP’13 because of the fears of their image 
being tarnished due to WORLDCOMP’s fraudulent activities. That is why WORLDCOMP’13 
is taking place at a different resort. WORLDCOMP will not be held after 2013. 

The draft paper submission deadline is over but still there are no committee 
members, no reviewers, and there is no conference Chairman. The only contact 
details available on WORLDCOMP’s website is just an email address! 

Let us make a direct request to Prof. Hamid arabnia: publish all reviews for 
all the papers (after blocking identifiable details) since 2000 conference. Reveal 
the names and affiliations of all the reviewers (for each year) and how many 
papers each reviewer had reviewed on average. We also request him to look at 
the Open Challenge (Section 6) at https://sites.google.com/site/moneycomp1 

Sorry for posting to multiple lists. Spreading the word is the only way to stop 
this bogus conference. Please forward this message to other mailing lists and people. 

We are shocked with Prof. Hamid Arabnia and his puppet’s activities

keyword worldcomp fake for additional links.

Last Call: <draft-ietf-bmwg-imix-genome-04.txt> (IMIX Genome: Specification of variable packet sizes for additional testing) to Informational RFC


The IESG has received a request from the Benchmarking Methodology WG
(bmwg) to consider the following document:
- 'IMIX Genome: Specification of variable packet sizes for additional
   testing'
  <draft-ietf-bmwg-imix-genome-04.txt> as Informational RFC

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf <at> ietf.org mailing lists by 2013-05-06. Exceptionally, comments may be
sent to iesg <at> ietf.org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.

Abstract

   Benchmarking Methodologies have always relied on test conditions with
   constant packet sizes, with the goal of understanding what network
   device capability has been tested.  Tests with constant packet size
   reveal device capabilities but differ significantly from the
   conditions encountered in operational deployment, and so additional
   tests are sometimes conducted with a mixture of packet sizes, or
   "IMIX".  The mixture of sizes a networking device will encounter is
   highly variable and depends on many factors.  An IMIX suited for one
   networking device and deployment will not be appropriate for another.
   However, the mix of sizes may be known and the tester may be asked to
   augment the fixed size tests.  To address this need, and the
   perpetual goal of specifying repeatable test conditions, this draft
   defines a way to specify the exact repeating sequence of packet sizes
   from the usual set of fixed sizes, and other forms of mixed size
   specification.

draft-constantine-bmwg-traffic-management-01.txt

Hi BMWG,

 

The new individual submission was posted today and we worked hard to incorporate many comments from Al, Gilles, and Shane received on the list.

 

The central focus of this revision was to augment the verification aspect of the first draft with capacity benchmarking for each traffic management area.  

 

An example would include the area of traffic shapers; the capacity benchmarking section specifies various combinations of stress test including:

-        Single shaper per port, all ports active

-        Multiple shapers per port, single port active

-        Combination of the first two; multiple shapers per port and all ports active

 

We hope that this version aligns to the charter of the BMWG and that the group would accept this as a formal work item as discussed in Orlando.

 

Thank you,

Barry Constantine

Traffic Management Benchmarking Alignment

Hi Folks,

 

First off, thanks to those that read this draft and provided feedback; the co-authors are working on some key revisions and hope to submit individual draft version 1 in mid-April.

 

One key point that Al made was that the work needed refinement to not only address traffic management verification testing, but to extend into the core scope of BMWG which includes capacity benchmarking, etc.

 

Our plan to accomplish this is summarized below and any feedback before we make the revisions will be appreciated.

 

Currently the draft is divided into several sections, each a specific traffic management function:

 

·        Buffer / Queue testing

·        Policing tests

·        Shaping tests

·        Congestion Management tests

 

Each individual test provides the test method and metrics that need to be measured in order to properly compare different vendor’s performance.

 

What we propose to add is a scalability test to each individual section, which tests each traffic management function to the rated limits; i.e. if each port can perform shaping at egress simultaneously, then the shaping  scalability test would provide the method to conduct that test

 

Scalability testing  of a combination of traffic management functions would be a daunting task (i.e. hierarchical QoS policies) and would be outside the scope of this work.  The draft may touch on the subject with general guidelines, but complex QoS policies would be deferred to potential follow-on drafts.

 

Thanks in advance for any feedback on this proposed alignment to BMWG charter.

 

Barry Constantine
