Dear NMRG,

This message starts the call for adoption as RG document for:
Digital Twin Network: Concepts and Reference Architecture - draft-zhou-nmrg=
-digitaltwin-network-concepts
https://datatracker.ietf.org/doc/draft-zhou-nmrg-digitaltwin-network-concep=
ts/

Please let us know if you support or not the work becoming a RG document.
In all cases, provide detailed comments to support your opinion and send th=
em on the mailing list.
We are particularly interested in assessing the following aspects:

  1.  NMRG being a *research* group it is important to articulate well the =
problem(s), challenge(s) and research questions.
  2.  Is the scientific soundness of the draft satisfying? (quality of the =
scientific proposition, rigor of the method, impact) ; "the measure of succ=
ess is the quality and impact of the research results" [RFC2014]
  3.  As the document proposes an *architecture*, it is important to provid=
e a clear scope and positioning of this architecture with respect to networ=
k management/automation/operation frameworks and where/how the proposed arc=
hitecture will prove useful or aims at replacing/augmenting certain functio=
nality

The procedure for RG document adoption and important criteria are detailed =
here: https://mailarchive.ietf.org/arch/msg/nmrg/CVEyLUvfxJk1Ud5WdM9Y5LGvQm=
U

Given the time of the year, this call for adoption is open for four weeks a=
nd ends on January 7th, 2022.

Best regards, NMRG chairs
Laurent & J=E9r=F4me

Hi, all
I have read the draft and support this work to become a RG document.
I believe that a common understanding of basic definition and architecture =
of digital twin networks is of great significance for the continuous resear=
ch of digital twin.

I have one question regarding the reference architecture: do we allow the a=
pplication layer to interact with physical network directly?
The user intent needs to be reflected into physical network after being tes=
ted/diagnosed on the virtual twin network, but do we allow applications to =
interact directly with the physical layer here?
Or do we think that physical network should only be controlled by digital t=
win network?


Best Regards,
Qiufang Ma

Subject: [nmrg] call for adoption as RG document : draft-zhou-nmrg-digitalt=
win-network-concepts

Dear NMRG,

This message starts the call for adoption as RG document for:
Digital Twin Network: Concepts and Reference Architecture - draft-zhou-nmrg=
-digitaltwin-network-concepts
https://datatracker.ietf.org/doc/draft-zhou-nmrg-digitaltwin-network-concep=
ts/

Please let us know if you support or not the work becoming a RG document.
In all cases, provide detailed comments to support your opinion and send th=
em on the mailing list.
We are particularly interested in assessing the following aspects:
1.       NMRG being a *research* group it is important to articulate well t=
he problem(s), challenge(s) and research questions.
2.       Is the scientific soundness of the draft satisfying? (quality of t=
he scientific proposition, rigor of the method, impact) ; "the measure of s=
uccess is the quality and impact of the research results" [RFC2014]
3.       As the document proposes an *architecture*, it is important to pro=
vide a clear scope and positioning of this architecture with respect to net=
work management/automation/operation frameworks and where/how the proposed =
architecture will prove useful or aims at replacing/augmenting certain func=
tionality

The procedure for RG document adoption and important criteria are detailed =
here: https://mailarchive.ietf.org/arch/msg/nmrg/CVEyLUvfxJk1Ud5WdM9Y5LGvQm=
U

Given the time of the year, this call for adoption is open for four weeks a=
nd ends on January 7th, 2022.

Best regards, NMRG chairs
Laurent & J=E9r=F4me

Hi Qiufang,=20

=20

Thanks for your support and good question.

Our understanding is that the application is using digital twin network =
layer to control the physical network indirectly. This way, control =
changes can be simulated and verified before being deployed onto =
physical network.

So, we think the application layer to interact with physical network =
directly is not in the scope of this draft.

=20

Thanks and Best Regards,

Cheng Zhou=20

Hi, all

I have read the draft and support this work to become a RG document.=20

I believe that a common understanding of basic definition and =
architecture of digital twin networks is of great significance for the =
continuous research of digital twin.

=20

I have one question regarding the reference architecture: do we allow =
the application layer to interact with physical network directly?=20

The user intent needs to be reflected into physical network after being =
tested/diagnosed on the virtual twin network, but do we allow =
applications to interact directly with the physical layer here?

Or do we think that physical network should only be controlled by =
digital twin network?

=20

Best Regards,

Qiufang Ma

Dear NMRG,

=20

This message starts the call for adoption as RG document for:

Digital Twin Network: Concepts and Reference Architecture - =
draft-zhou-nmrg-digitaltwin-network-concepts

https://datatracker.ietf.org/doc/draft-zhou-nmrg-digitaltwin-network-conc=
epts/

=20

Please let us know if you support or not the work becoming a RG =
document.

In all cases, provide detailed comments to support your opinion and send =
them on the mailing list.

We are particularly interested in assessing the following aspects:

1.       NMRG being a *research* group it is important to articulate =
well the problem(s), challenge(s) and research questions.=20

2.       Is the scientific soundness of the draft satisfying? (quality =
of the scientific proposition, rigor of the method, impact) ; =
=E2=80=9Cthe measure of success is the quality and impact of the =
research results=E2=80=9D [RFC2014]

3.       As the document proposes an *architecture*, it is important to =
provide a clear scope and positioning of this architecture with respect =
to network management/automation/operation frameworks and where/how the =
proposed architecture will prove useful or aims at replacing/augmenting =
certain functionality

=20

The procedure for RG document adoption and important criteria are =
detailed here: =
https://mailarchive.ietf.org/arch/msg/nmrg/CVEyLUvfxJk1Ud5WdM9Y5LGvQmU

=20

Given the time of the year, this call for adoption is open for four =
weeks and ends on January 7th, 2022.

=20

IFIP Networking Conference 2022
https://networking.ifip.org/2022/
Call for Workshop Proposals

+ Workshop proposal submission: 10 January 2022
+ Workshop acceptance notification: 17 January 2022
+ Proposals should be sent by e-mail to pedro.casas@ait.ac.at<mailto:pedro.=
casas@ait.ac.at>

IFIP Networking 2022, hosted by the University of Catania in Sicily, Italy,=
 is soliciting proposals for one-day workshops, to will be held on 13 June =
2022 during the conference week.
Accepted papers will be published in the IFIP Digital Library as open acces=
s and submitted to IEEE Xplore Digital Library (pending).
The main purpose of the IFIP Networking 2022 Workshops is to provide fora f=
or research, development, integration, standards, service provisioning, and=
 user communities addressing timely topics relevant to the main conference.
Workshops can take different styles, for example, targeting students, speci=
alizing on a scientific topic area, or fostering interaction between academ=
ia and industry. We encourage fresh topics and workshop styles.

SUBMISSION GUIDELINES

Each workshop proposal, in a single PDF file, must include:


  1.  Title of the workshop and abbreviation.
  2.  Names, affiliations, e-mail addresses, and a short (200 words) bio of=
 the co-chairs and possibly other main organizers.
  3.  A brief description (max. 1 page) of the technical issues addressed b=
y the workshop. State reasons why and how the workshop would attract the IF=
IP Networking 2022 audience.
  4.  Technical Program Committee (TPC), indicating which of the TPC member=
s already accepted and which are tentative
  5.  The planned format of the workshop (including other elements besides =
technical sessions are foreseen) and how to facilitate lively and interacti=
ve discussions. The format should also have a fallback plan in case IFIP Ne=
tworking 2022 should go virtual.
  6.  If applicable, a description of the past events of the workshop, incl=
uding website address, and statistics of submitted/accepted papers and atte=
ndee numbers. If the workshop does not have past editions, please provide e=
stimates and explain a strategy on how to reach the targets of paper submis=
sions and attendees.
  7.  Publicity and advertising plan to attract paper submissions and atten=
dees.
  8.  A draft of 1-page "Call for Papers (CFP)" including title, descriptio=
n, topics and important dates (see also the tentative important dates below=
).

Submission of workshop proposals should be made to the Workshop Chairs of I=
FIP Networking 2022 by e-mail to the following address: pedro.casas@ait.ac.=
at<mailto:pedro.casas@ait.ac.at>, indicating in the subject "IFIP Networkin=
g 2022 Workshop Proposal".
Selection of workshops will be made by the Workshop Chairs, in consultation=
 with the Conference General chairs.

Hello Colin, and all,

it has taken us a while, but we have now updated the draft per your 
comments as follows and hope it addresses your concerns so you will send 
it for IRSG review. We are posting -06 shortly.

Re: 1 (better relate it to current research needs):

We are adding the following paragraph, at the end of section 1, to 
indicate the growing relevance in the research community.

/Intent has also become an important topic in the research community.  
Per IEEE Xplore [Reference: //https://ieeexplore.ieee.org///] , in the 
past decade since 2012, there have been 1138 papers with the index term 
"intent", of which 411 specifically mention networking.  The time period 
since 2020 alone accounts for 316 papers on intent and 153 for intent 
networking, indicating accelerating interest.  In addition, workshops 
dedicated to this theme are beginning to appear, such as the IEEE 
International Workshop on Intent-Based Networking [Reference: 
//https://netsoft2021.ieee-netsoft.org/program/workshops/win-2021///], 
as well as various special journal issues [Reference: Special Issue on 
Intent-Based Networking for 5G-Envisioned Internet of Connected 
Vehicles, in IEEE Transactions on Intelligent Transportation Systems, 
vol. 22, no. 8, DOI: 10.1109/TITS.2021.3101259, August 2021] [Reference: 
Special Issue "Intent-Based Software-Defined Networks", in Computers 
(MDPI), M. Gharbaoui (editor), 2022, to appear].  A survey of current 
intent-driven networking research has been published in [L. Pang, C. 
Yang, D. Chen, Y. Song, M. Guizan, "A Survey on Intent-Driven Networks", 
in IEEE Access Vol 8 pp. 22862-22873, 2020, DOI: 
10:110/ACCESS.2020.2969208], listing among the current research 
challenges aspects such as intent translation and understanding, intent 
interfaces, and security.  The survey highlights that there is no common 
terminology and calls out the lack for uniform understanding and 
standardization as a potential inhibitor for the further development  of 
IBN.
/

As an FYI (we are not mentioning this in the document), per Google 
Scholar, the current draft has already received 47 citations, which is 
also indicative of its relevance to the research community; see here: 
https://scholar.google.com/citations?view_op=view_citation&hl=en&user=YGBQsCQAAAAJ&cstart=20&pagesize=80&sortby=pubdate&citation_for_view=YGBQsCQAAAAJ:OP4eGU-M3BUC

Re: 2: We believe that much of this should be answered by our response 
to the first question.  We will add the references to the current survey 
as per the above.  The examples that we chose are indeed 
networking-centric and intended to make them easily relatable to a 
networking audience without needing much explanation about the example 
domain.  We disagree that these are "old" problems, some (such as the  
intent to generate in-situ OAM data under certain conditions, or 
intent-based traffic steering based on geographic considerations) are 
certainly very current. That said, we can add some more "researchy" 
examples of intent from research papers, as follows:

/- "Route traffic in a Space Information Network in a way that minimizes 
dependency on stratospheric balloons unless the intended destination is 
an aircraft." (Does not specify how to precisely achieve this; 
extrapolates on scenarios mentioned in [Survey] //
/

//

/- "For a smart city service, ensure traffic signal control traffic uses 
dedicated and redundant slices that avoid fate sharing." (A desired 
outcome with a set of constraints and additional guidance without 
specifying how to precisely achieve this;  extrapolates on scenarios 
from[Reference: M. Gharbaoui, B. Martini, P. Castoldi, "Implementation 
of an Intent Layer for SDN-enabled and QoS-aware Network Slicing", in 
2021 IEEE 7th Int. Conference on Netowrk Softwarization (NetSoft), pp 
17-23, doi: 10.1109/NetSoft51509.2021.9492643.] /

Re: 3, we will repeat the statement from the abstract in the 
Introduction.  We are putting this in the beginning so it is very clear:

/This document is a product of the IRTF Network Management 
Research//Group (NMRG). It reflects the consensus of the RG, receiving 
reviews and explicit support from many members./

Re: 4, as mentioned before, we will reword the first sentence to avoid 
the term "traditionally" as follows:

/In the past, interest regarding management and operations in the IETF 
has focused largely on individual network and device features./

Please let us know if these modifications address your concerns.

Thank you

--- Alex (on behalf of coauthors)

Similarly, there are no conclusions drawn, and no attempt to summarise and relate the work to ongoing research. The definitions and discussion of concepts is good, but the draft needs to better relate it to ongoing research needs and trends.

As IRTF Chair, I perform an initial review of all drafts submitted for publication on the IRTF stream before sending them for detailed review by the IRSG. This note provides my review comments, for discussion.

Result:
* Almost ready

RFC 5743 compliance:
* The draft does not follow the guidelines in RFC 5743


Comments:

* The structure and focus of the Introduction suggests that this is an IETF document, primarily discussing standards and saying little about the research need for this document. Similarly, there are no conclusions drawn, and no attempt to summarise and relate the work to ongoing research. The definitions and discussion of concepts is good, but the draft needs to better relate it to ongoing research needs and trends.

* Most of the examples are standards-based, and the few that point to research work are to old papers. How does the work relate to current research?

* RFC 5843, Section 2.1, requires all IRTF stream documents to include certain statements in the Abstract and Introduction. The necessary statements appear in the Abstract, but appear to be missing from the Introduction.

* First sentence: “Traditionally in the IETF…” – the RFC Editor will flag the use of the word “traditionally” in their review of inclusive language. Suggest rephrasing.

Abstract:
   Intent and Intent-Based Networking (IBN) are taking the industry by
   storm.  At the same time, IBN-related terms are often used loosely
   and inconsistently, in many cases overlapping and confused with other
   concepts such as "Policy."  This document clarifies the concept of
   "Intent" and provides an overview of the functionality that is
   associated with it.  The goal is to contribute towards a common and
   shared understanding of terms, concepts, and functionality that can
   be used as the foundation to guide further definition of associated
   research and engineering problems and their solutions.

   This document is a product of the IRTF Network Management Research
   Group (NMRG).  It reflects the consensus of the RG, receiving reviews
   and explicit support from many members.  It is published for
   informational purposes.

ACM SIGCOMM 2022
August 22-26, 2022
Amsterdam, the Netherlands
https://conferences.sigcomm.org/sigcomm/2022/

***Important dates***

  *   Jan 26, 2022, 23:59 UTC -- Abstract registration deadline
  *   Feb 2, 2022, 23:59 UTC -- Paper submission deadline
  *   April 14/May 7, 2022 - Early/Notification date


***Call for Papers***

The ACM SIGCOMM 2022 conference seeks papers describing significant researc=
h contributions to the field of communication networks and networked system=
s. SIGCOMM takes a broad view of networking research, which includes (but i=
s not limited to) the following topics:


  *   All types of computer networks such as mobile, wide-area, data-center=
, embedded, home, and enterprise networks.
  *   All types of wired and wireless technologies, including optics, radio=
, and acoustic and visible light-based communication.
  *   All aspects of networks and networked systems such as architecture, p=
acket-processing hardware and software, virtualization, mobility, resource =
management, performance, energy consumption, topology, robustness, security=
, diagnosis, verification, privacy, economics, evolution, and interactions =
with applications.
  *   All types of computer network design, analysis, and experimental appr=
oaches such as theory, measurements, and machine learning-based techniques.

SIGCOMM 2022 will accept submissions in two tracks.  In the regular researc=
h track, papers should significantly advance the state-of-the-art in networ=
king by, for instance, proposing and developing novel ideas or rigorously (=
re-)evaluating existing ideas. The review process will take the nature of t=
he contribution into account. We strongly encourage authors to discuss not =
only the benefits but also the limitations of their work.

In the experience track, submissions should describe the design, analysis, =
and evaluation of techniques in commercial or otherwise widely-used deploym=
ent. Experience track submissions need not describe new ideas, but are stro=
ngly encouraged to elucidate key insights and takeaways gathered from desig=
n, deployment, or operational experience. The PC will evaluate these submis=
sions with the understanding that the primary contributions may be in exten=
ding the SIGCOMM community's knowledge of how known techniques fare when ad=
apted to real-world settings, and particularly in settings that most in the=
 community cannot duplicate, for reasons of scale or otherwise. All submiss=
ions must be double-blind (not revealing author names), but due to the natu=
re of experience track submissions, they may reveal the company or system n=
ame.

At paper registration time, authors must explicitly indicate both in their =
paper title and submission form if their paper is preferred to be considere=
d for the experience or regular research track. Each submission will only b=
e considered for the one track identified at submission time. The final con=
ference program will not preserve the distinction between the two tracks.

In addition to the main conference, SIGCOMM 2022 will have a series of co-l=
ocated workshops, tutorials, poster and demo sessions, and conference best =
paper and SIGCOMM awards.


***Submissions***

Papers submitted to SIGCOMM typically report novel results firmly substanti=
ated by experimentation, deployment, simulation, or analysis. The program c=
ommittee will judge submissions based upon novelty, significance, correctne=
ss, clarity of presentation, and relevance to the SIGCOMM community.

Submissions should be in two-column, 10-point format, and can be up to 12 p=
ages in length with as many additional pages as necessary for references an=
d optional appendices.

Submissions and final papers may include appendices (following references, =
not counting against the 12 pages). Reviewers are not required to read appe=
ndices or consider them in their review. Authors should thus ensure that th=
e core paper is complete and self-contained. For example, if the appendix p=
rovides details of a proof or experiment, the body should summarize the key=
 result.  Appendices may also include non-traditional material, such as vid=
eos, datasets, and code, all appropriately anonymized.

The review process will involve two rounds.  Papers that are not selected t=
o proceed after the first round will receive early notification, including =
reviews.

All accepted papers will be shepherded by a member of the program committee=
 to ensure the committee's feedback is appropriately addressed.  The shephe=
rd will also review appendices and must approve their necessity.

For accepted papers, the official publication date is the date the proceedi=
ngs are made available in the ACM Digital Library. This date may be up to t=
wo weeks prior to the first day of the conference. The official publication=
 date affects the deadline for any patent filings related to published work=
. (For those rare conferences whose proceedings are published in the ACM Di=
gital Library after the conference is over, the official publication date r=
emains the first day of the conference.)

Detailed submission instructions can be found here --> https://conferences.=
sigcomm.org/sigcomm/2022/submission.html

Submission site: https://sigcomm2022.hotcrp.com


***Artifact Evaluation for Accepted Papers***

The authors of accepted SIGCOMM 2022 papers will be invited to submit suppo=
rting materials to the Artifact Evaluation process. Artifact Evaluation is =
run by a separate committee that will assess how well the submitted artifac=
ts support the work described in the accepted papers. Participation in Arti=
fact Evaluation is voluntary and has no influence on the paper's acceptance=
, but is strongly encouraged. Papers that go through the Artifact Evaluatio=
n process successfully will receive badges printed on the papers themselves=
. Additional details on the Artifact Evaluation process can be found here.


***Public Summaries for Accepted Papers***

The SIGCOMM 2022 program will feature public summaries accompanying each ac=

***Ethical Concerns***

All papers must include, in the main body of the paper, a statement about e=
thical issues; papers that do not include such a statement may be rejected.=
 This could be, if appropriate for the paper, simply the sentence "This wor=
k does not raise any ethical issues." If the work involves human subjects o=
r potentially sensitive data (e.g., user traffic or social network informat=
ion, evaluation of censorship, etc.), the paper should clearly discuss thes=
e issues, perhaps in a separate subsection.

Papers must follow basic precepts of ethical research and subscribe to comm=
unity norms. These include respect for privacy, secure storage of sensitive=
 data, voluntary and informed consent if human subjects are involved or oth=
er people are placed at risk, avoiding deceptive practices when not essenti=
al, beneficence (maximizing the benefits to an individual or to society whi=
le minimizing potential harm to an individual), and risk mitigation. Author=
s may want to consult the Menlo Report and the ACM ethics policy for furthe=
r information on ethical principles, and they may find the Allman/Paxson pa=
per in IMC 2007 helpful for a perspective on ethical data sharing.

Many organizations have an ethics review process (sometimes called an Insti=
tutional Review Board, IRB). In some cases, research work may clearly have =
no human subjects, and formal institutional review may not be required. (Ho=
wever, a sentence in the paper stating this evaluation is still required.) =
In many cases, IRB involvement is appropriate. IRB approval of research is =
an important factor and should be mentioned, but the program committee will=
 independently evaluate the ethical soundness of the work just as they eval=
uate its technical soundness.

The PC takes a broad view of what constitutes an ethical concern, and the P=
C chairs may reach out to authors during the review process if questions ar=
ise.

ts of ethical research and subscribe to community norms. These include resp=
ect for privacy, secure storage of sensitive data, voluntary and informed c=
onsent if human subjects are involved
 or other people are placed at risk, avoiding deceptive practices when not =
essential, beneficence (maximizing the benefits to an individual or to soci=
ety while minimizing potential harm to an individual), and risk mitigation.=
 Authors may want to consult the
 Menlo Report and the ACM ethics policy for further information on ethical =
principles, and they may find the Allman/Paxson paper in IMC 2007 helpful f=
or a perspective on ethical data sharing.<o:p></o:p></span></p>

<p class=3D"MsoNormal"><span lang=3D"EN-US">Many organizations have an ethi=
cs review process (sometimes called an Institutional Review Board, IRB). In=
 some cases, research work may clearly have no human subjects, and formal i=
nstitutional review may not be required.
 (However, a sentence in the paper stating this evaluation is still require=
d.) In many cases, IRB involvement is appropriate. IRB approval of research=
 is an important factor and should be mentioned, but the program committee =
will independently evaluate the
 ethical soundness of the work just as they evaluate its technical soundnes=
s.<o:p></o:p></span></p>

IEEE/IFIP ANMS 2022 =96 CALL FOR PAPERS
1st Workshop on Autonomous Network Management in 5G and beyond Systems (ANM=
S 2022)
Co-located with IFIP/IEEE NOMS 2022
Apr 25--29, 2022 // Budapest, Hungary
    Paper Submission: Jan 23, 2022
                                                              https://h2020=

***************************************************************************=
****************************
New networking systems aim to be fully Autonomous Networks (ANs) with manag=
ement capabilities such as self-configuration, self-healing, self-optimizin=
g, and self-evolving, aspects that today=92s networks do not support as the=
ir management is mainly manual with some automated assistance. Artificial I=
ntelligence (AI) (and more precisely Machine Learning (ML)) algorithms are =
promising to empower the new generation of intelligent decision engines tha=
t present self-dynamic capabilities to fully realize ANs. ANMS workshop foc=
uses on novel research in AI-based and hybrid approaches (AI + non-AI) algo=
rithms for AN management (closed-loop control) and Framework, algorithms, t=
echniques, and tools to build and support AI-based solutions for ANs.

Topics of interest include, but are not limited to:

AI-based and hybrid approaches (AI + non-AI) algorithms for AN management (=
closed loop control):

  *   Decentralized management of multi-domain ANs.
  *   End-to-end lifecycle of ANs.
  *   Network resource and service automation and orchestration.
  *   Automated network operation and maintenance.
  *   Intelligent service provisioning and assurance.
  *   Wireless network coverage optimization and assurance.
  *   Wireless network energy saving.
  *   Intelligent slice lifecycle management.
  *   Metadata-driven policies to recognize and incorporate new knowledge i=
n AN.
  *   Efficient resource allocation and scheduling (e.g., spectrum, storage=
, computing, processing).
  *   Network state prediction and forecasting for AN.
  *   Network monitoring systems (traffic recognition, anomaly detection, e=
tc.) for AN.
  *   AN management in resource-constrained environments.
  *   AN management in Mobile Radio Access Networks (RANs) and Wireless Loc=
al Area Networks (WLANs).
  *   AN management in cognitive radio networks and opportunistic spectrum =
access.
  *   AN management in Mobile Edge Computing (MEC).
  *   AN Management in Transport Networks (TNs).
  *   End-to-end management of AN.
  *   Security provision in ANs
Framework, algorithms, techniques, and tools to build and support AI-based =
solutions for ANs:

  *   Architectures and frameworks to integrate AI in AN management (e.g., =
MLOps optimized for networking).
  *   Algorithms, techniques, methods and tools from AI adapted to network =
management (e.g., online learning, reinforcement learning, hierarchical lea=
rning, multi-task learning, federated learning, transfer learning, spike ne=
ural networks, graph neural networks, resource-aware AI, explainable AI, on=
e-shot learning, etc.).
  *   Guidelines for designing and benchmarking AI-based solutions for netw=
ork management.
  *   Energy-efficient techniques for data pre-processing, resource allocat=
ion, and model training and deployment of AI-based algorithms.
  *   Lightweight communication protocols for AI-embedded network managemen=
t (e.g., neural networks compression).
  *   AI-enabled network simulation tools, testbeds, or hardware implementa=
tions

Paper submissions must present original, unpublished research or experience=
s. Only original papers that have not been published or submitted for publi=
cation elsewhere can be submitted. Each submission must be written in Engli=
sh, accompanied by a 75 to 200 words abstract that clearly outlines the sco=
pe and contributions of the paper. There is a length limitation of 6 pages =
(including title, abstract, all figures, tables, and references) for regula=
r papers, and 4 pages for short papers describing work in progress. Submiss=
ions must be in IEEE 2-column style. Self-plagiarized papers will be reject=
ed without further review. Authors should submit their papers via the follo=
wing link: https://jems.sbc.org.br/home.cgi?c=3D4018

Extended versions of the best paper(s) may be considered for fast-tracking =
to the Journal of Network and Systems Management (confirmed, https://www.sp=
ringer.com/journal/10922, IF 2.026). The decision will depend on the qualit=
y and scope of the paper(s) and its (their) potential to spark lively discu=
ssion(s) at the workshop. The final decision will be made by the co-chairs =
after the workshop.

Hi Alex,

Thank you for updating the draft.

The changes around terminology and consensus are fine.

The other changes to the Introduction, to highlight that there is =
research on intent-based networking, are less convincing. It=E2=80=99s =
clear that the topic of intent-based networking is one that's receiving =
interest from the community, but I was rather interested in =
understanding how this draft fits with ongoing research since the =
Introduction is so heavily focussed on standards. Reviewing the =
citations you highlight in Google Scholar, however, makes it clear that =
the definitions are broadly useful to the research community.=20

Accordingly, I'll move this draft forward to IRSG review if the chairs =
are happy with the changes.=20

I would, however, ask the document shepherd to update the write-up in =
the datatracker to highlight the papers and research that build on this =
draft =E2=80=93 this would make it=E2=80=99s relevance to the research =
community clearer.

Colin

As IRTF Chair, I perform an initial review of all drafts submitted for =
publication on the IRTF stream before sending them for detailed review =
by the IRSG. This note provides my review comments, for discussion.

Result:
* Almost ready

RFC 5743 compliance:
* The draft does not follow the guidelines in RFC 5743


Comments:

* The structure and focus of the Introduction suggests that this is an =
IETF document, primarily discussing standards and saying little about =
the research need for this document. Similarly, there are no conclusions =
drawn, and no attempt to summarise and relate the work to ongoing =
research. The definitions and discussion of concepts is good, but the =
draft needs to better relate it to ongoing research needs and trends.

* Most of the examples are standards-based, and the few that point to =
research work are to old papers. How does the work relate to current =
research?

* RFC 5843, Section 2.1, requires all IRTF stream documents to include =
certain statements in the Abstract and Introduction. The necessary =
statements appear in the Abstract, but appear to be missing from the =
Introduction.

* First sentence: =E2=80=9CTraditionally in the IETF=E2=80=A6=E2=80=9D =

The IRTF publication process is described in RFC 5743, and comprises a review by the IRSG to ensure technical and editorial quality, followed by a check by the IESG to ensure the work does not conflict with IETF standards activities. 

As IRTF Chair, I perform an initial review of all drafts submitted for publication on the IRTF stream before sending them for detailed review by the IRSG. This note provides my review comments, for discussion.

Result:
* Almost ready

RFC 5743 compliance:
* The draft does not follow the guidelines in RFC 5743


Comments:

* The structure and focus of the Introduction suggests that this is an IETF document, primarily discussing standards and saying little about the research need for this document. Similarly, there are no conclusions drawn, and no attempt to summarise and relate the work to ongoing research. The definitions and discussion of concepts is good, but the draft needs to better relate it to ongoing research needs and trends.

* Most of the examples are standards-based, and the few that point to research work are to old papers. How does the work relate to current research?

* RFC 5843, Section 2.1, requires all IRTF stream documents to include certain statements in the Abstract and Introduction. The necessary statements appear in the Abstract, but appear to be missing from the Introduction.

* First sentence: “Traditionally in the IETF…” – the RFC Editor will flag the use of the word “traditionally” in their review of inclusive language. Suggest rephrasing.

Content-Type: text/plain; charset="UTF-8"

Dear all,

My name is Qiao Xiang and I am a member of the ALTO WG. I have been
following some drafts in NMRG because they are related to network
information abstraction and exposure, which is exactly what ALTO focuses
on. I am writing to share some thoughts about the digital twin network
draft (draft-zhou-nmrg-digitaltwin-network-concepts),

Overall, I find this draft providing a clean view about the research topic
of digital twin network, in particular its goal, potential use cases and
key challneges. Digital twin network aims to provide a unified view
(including both configurations and network state) of the physical network,
and how to use this unified view to achieve automatic, intelligent and
intent-based network management of large networks such as DCN.

In this draft, a reference architecture is presented, which puts instances
of digital twin network into a middle layer between applications and the
physical networks. The 3-layer design has been adopted by many major IT
companies, such as Robotron in Facebook (in SIGCOMM'18), and MALT/Orion in
Google (in NSDI'20 and '21), to play a major role in simplifying their
daily network operations and management. But by putting digital twin
network into the middle layer, and letting it collect information from
physical networks, process and encode the collected information in
abstractions, and expose them to the applications, not only can we automate
the deep integration between network and application, but also we can let
applications to be able to fully utilize the huge amount of resources in
the network, to improve their performance. So personally, I think this
architecture is promising, and could shed light for many future research
opportunities in network management and automation.

To summarize, overall I find this draft trying to position digital twin
network as a major research direction to further improve the efficiency of
network management. It articulates the scientific soundness and the key
challenges of this direction, and provides a clean, promising reference
architecture that can motivate many future research. So IMHO, I would
advocate this draft being adopted by the NMRG.

Paper Submission

----------------

Prospective authors are invited to submit high-quality original 
technical papers for presentation at the conference and publication in 
the NetSoft 2022 Proceedings. All submissions must be written in English 
and must use standard IEEE two-column conference template that can be 
downloaded from https://www.ieee.org/conferences/publishing/templates.html.


Technical Papers can be of two types: Full or Short papers, up to 9 and 
5 pages respectively, including references and all other material. If 
accepted, a paper will be published in the category (long/short) of its 
submission. Long papers are the more traditional form to present 
technical work. Long papers should emphasize not only novelty and 
vision, but execution and thoroughness of the contribution (design, 
evaluation). Short papers are the preferred vehicle for visionary papers 
or traditional technical papers whose description fits within a smaller 
number of pages. Short papers may not yet be 'fully baked' in terms of 
execution and evaluation. In both Full and Short papers, author names 
and affiliations should be included after the title, as provided in the 
templates.


Papers submitted should describe original, previously unpublished 
research results, not currently under review by another conference or 
journal. Papers not meeting the length and formatting requirements or 
violating IEEE's guidelines on plagiarized content will be rejected 
without review.  All other submitted papers will be reviewed. Selected 
papers for NetSoft 2022 may be conditionally accepted and subjected to 
shepherding before final acceptance.


Only PDF files will be accepted for the review process and all 
manuscripts must be electronically submitted through EDAS: 
https://edas.info/newPaper.php?c=28960


Important: NetSoft 2022 is enforcing a strict publication and no-show 
policy as stated by IEEE. By submitting a contribution, you agree with 
the terms of the publication and no-show policy as mentioned here.

        has become the core value provider in the telecommunications
        industry. Boosted by scientific breakthroughs, continuous
        innovation and stringent requirements for new services, network
        softwarization is currently transforming telecommunications and
        networking industry and is bringing several opportunities, while
        raising new challenges, from both conceptual and operational
        perspectives. While 5G technologies have adopted network
        softwarization as a foundation, many challenges remain for
        end-users to see their benefits, and for the software-based
        network to add user and provider perceived value.</span></p>

        papers whose description fits within a smaller number of pages.
        Short papers may not yet be 'fully baked' in terms of execution

Hi Colin, Alex,

As NMRG co-chair and shepherd, I'm fine with the new version.
As mentioned in the email discussion, this draft is well cited and can be thus 
considered as an helpful document for other research papers. I'll update the write 
up accordingly.

      <div class="">The other changes to the Introduction, to highlight
        that there is research on intent-based networking, are less
        convincing. It’s clear that the topic of intent-based networking
        is one that's receiving interest from the community, but I was
        rather interested in understanding how this draft fits with
        ongoing research since the Introduction is so heavily focussed
        on standards. Reviewing the citations you highlight in Google
        Scholar, however, makes it clear that the definitions are
        broadly useful to the research community. </div>
      <div class=""><br class="">

      <div class="">I would, however, ask the document shepherd to
        update the write-up in the datatracker to highlight the papers

                    have been 1138 papers with the index term "intent",
                    of which 411 specifically mention networking.  The

                    on intent and 153 for intent networking, indicating
                    accelerating interest.  In addition, workshops

                <p class="">Re: 2: We believe that much of this should
                  be answered by our response to the first question.  We
                  will add the references to the current survey as per
                  the above.  The examples that we chose are indeed
                  networking-centric and intended to make them easily
                  relatable to a networking audience without needing
                  much explanation about the example domain.  We
                  disagree that these are "old" problems, some (such as
                  the  intent to generate in-situ OAM data under certain
                  conditions, or intent-based traffic steering based on
                  geographic considerations) are certainly very
                  current.  That said, we can add some more "researchy"

The IRTF publication process is described in RFC 5743, and comprises a review by the IRSG to ensure technical and editorial quality, followed by a check by the IESG to ensure the work does not conflict with IETF standards activities. 

As IRTF Chair, I perform an initial review of all drafts submitted for publication on the IRTF stream before sending them for detailed review by the IRSG. This note provides my review comments, for discussion.

Result:
* Almost ready

RFC 5743 compliance:
* The draft does not follow the guidelines in RFC 5743


Comments:

* The structure and focus of the Introduction suggests that this is an IETF document, primarily discussing standards and saying little about the research need for this document. Similarly, there are no conclusions drawn, and no attempt to summarise and relate the work to ongoing research. The definitions and discussion of concepts is good, but the draft needs to better relate it to ongoing research needs and trends.

* Most of the examples are standards-based, and the few that point to research work are to old papers. How does the work relate to current research?

* RFC 5843, Section 2.1, requires all IRTF stream documents to include certain statements in the Abstract and Introduction. The necessary statements appear in the Abstract, but appear to be missing from the Introduction.

* First sentence: “Traditionally in the IETF…” – the RFC Editor will flag the use of the word “traditionally” in their review of inclusive language. Suggest rephrasing.

CALL FOR WORKSHOP PAPERS

WIN 2022: 2nd International Workshop on Intent-based Networking

co-located with IEEE International Conference on Network Softwarization 
(NetSoft)  - 27 June - 1 July 2022, Milan, Italy

Workshop paper submission deadline: February 28, 2022
================================================================

Aim and Scope
=============
Intent Based Networking (IBN) aims at technology-agnostic, fast and 
robust interaction between network infrastructure management systems and 
their users, in order to automate and speed up the deployment and 
lifecycle of applications. IBN as such covers mechanisms to recognize, 
understand and augment intents defining service or operational requests, 
so as to ensure their fulfillment, with the support of reliable system 
feedback enabling their execution within the expected quality limits.
The concept of IBN appeared in the 2010’s with a focus on automated 
policy configuration. IBN now reaches out to OTT applications deployed 
on multiple and heterogeneous networks. IBN solutions do not aim at 
covering all applications and the entire network. Instead, they are 
deemed to run in a well-defined network scope and associated knowledge 
domains. That said, IBN solutions need to have enough flexibility to 
span and exchange with connected domains.
The goal of this workshop is to gather research and experiments from 
industry, academia, and standards, to get a sense of where we stand, 
what needs to be addressed and what should be explored. To this end, the 
workshop will cover IBN aspects of all domains including applications, 
concepts, lifecycle, challenges, architectures, modeling, instantiation, 
robustness, etc.

Topics of Interest
==================
* IBN concepts, architectures, and frameworks
* IBN enabling techniques: knowledge graphs, natural languages 
understanding, policy refinement, feedback control loops, smart 
telemetry, various artificial intelligence methods, etc.
* IBN applications and use cases, including scenarios combining digital 
infrastructures and vertical industries
* IBN proof-of-concepts, experimentations; report on field trials and 
real-world deployments
* IBN implementations, tools, and user interface design
* IBN applications for 5G, beyond-5G and 6G networks
* Intent modeling, representation, languages, and intent translation 
techniques
* Intent and intent-related information models (policies and services)
* Intent recognition, recommendation, and abstraction techniques
* Availability, resiliency, performance, trust, and security 
considerations in IBN
* Interfaces and API for intent based systems
* Recent advances in standards and open source

Important Dates
===============
* Paper Submission: February 28, 2022
* Notification of Acceptance: April 11, 2022
* Camera-ready Submission: April 25, 2022
* Workshops Date: Either Monday June 27th, 2022 or Friday July 1st, 2022

Submission
==========
A selection of the best papers will be further considered for possible 
publication in IEEE Journals and Magazines with high impact factors.
Only PDF files will be accepted for the review process and all 
manuscripts must be electronically submitted through 
EDAS: https://www.edas.info/chair.php?c=29267

Hi RG,



Having read the draft, I think it's a valuable work item for the RG, and I =
support the adoption of the I-D. However, significant work by the authors a=
nd input from the RG will be required, as expected with a recently adopted =
document.



In response to the questions posed:



Q1.  NMRG being a *research* group, it is important to articulate well the =
problem(s), challenge(s) and research questions.



Yes, but. The document would benefit from several significant updates that =
are proposed in more detail below.



Q2. Is the scientific soundness of the draft satisfying? (quality of the sc=
ientific proposition, rigor of the method, impact) ; "the measure of succes=
s is the quality and impact of the research results" [RFC2014]



Within reason. The document is informational and provides an overview of th=
e digital twin network state of the art. It would benefit from resequencing=
 sections and more academic research papers/journals that also cite common =
challenges. The authors discuss a broad set of use cases. It may be better =
to focus on one or two initially and go deeper in the discussion.



3.  As the document proposes an *architecture*, it is important to provide =
a clear scope and positioning of this architecture with respect to network =
management/automation/operation frameworks and where/how the proposed archi=
tecture will prove useful or aims at replacing/augmenting certain functiona=
lity.



I think the document's readability would be improved if the authors made th=
e core requirements and research challenge more evident/earlier in the docu=
ment, perhaps as research questions raised by the authors and citing other =
research (a few links provided below) that highlights challenges. Then when=
 the authors present the architecture and functional components, they could=
 may how it solves the specific challenges outlined earlier in the document=
.



Please find my specific comments and numerous editorial suggestions and que=
stions below.



1. Introduction



Replace: "The fast growing of network scale and the increased demand placed=
 on these networks, requires them to accommodate and adapt dynamically to c=
ustomer needs, implying a big challenge to network operators."



With: "The fast growth of network scale and the increased demand placed on =
these networks require them to accommodate and adapt dynamically to custome=
r needs, implying a significant challenge to network operators."



Replace: "Indeed, network operation and maintenance are becoming more compl=
ex due to the higher complexity of the managed networks and their sophistic=
ated services."



With: "Indeed, network operation and maintenance are becoming more complex =
due to the higher complexity of the managed networks and their sophisticate=
d services."



Replace: "full lifecycle and full business data-driven."



With: "full lifecycle and comprehensive business data-driven."



Replace: "The main difference compared to traditional network management sy=
stem is the use of interactive virtual-real mapping to build closed-loop ne=
twork automation."



With: "The main difference compared to traditional network management syste=
ms is interactive virtual-real mapping to build closed-loop network automat=
ion."



Replace: " Having an emulation platform that allows to reliably represent t=
he state of a network is more dependable than a simulation platform."



With: " An emulation platform that highlights the state of network reliabil=
ity provides a more helpful simulation platform."



Replace: " Service impact analysis tasks will also be facilitated."



With: " In addition, service impact analysis tasks will also be facilitated=
."



At this point, I just exported the text I-D into an MS Word document, enabl=
ed change markers and edited directly. I will provide this to the authors a=
s an MS Word file.



2. Requirements Language



As an informational document, do you need to use specific requirement langu=
age? If you intend to have hard and soft requirements in future discussions=
, it may make more sense to keep this section.



3. Definitions and Acronyms



This section feels a little light given the various technology areas you di=
scuss. Also, it only provides expanded acronym definitions, and I would thi=
nk some definitions such as "digital twin" would also be helpful.



4. Definition of Digital Twin Network



The concept of "digital twin" predates 2003 (Michael Grieves). My understan=
ding is "digital twin" was initially coined by NASA in the 1970s during the=
 Apollo 13 program so that terrestrial engineers could model the extra-terr=
estrial effects on  Apollo 13 objects and systems. You might want to update=
 your etymology and add a citation, such as "S. Ferguson, "Apollo 13: The F=
irst Digital Twin", Article by Siemens Blogs, April 14, 2020. https://blogs=
.sw.siemens.com/simcenter/apollo-13-the-first-digital-twin/"



Before you define "digital twin network", you might want to enlighten the r=
eaders about the "digital twin" concept. This might be a definition in sect=
ion 3., or a paragraph in section 5 along the lines of:



>>

"A digital twin is a virtual representation of the real-time digital counte=
rpart, including physical objects, systems or processes. A digital twin is =
generated by gathering data and simulating the environment so that machine =
learning reasoning may be applied, often the entire lifecycle of the object=
 or system is also represented."

<<



It may be useful to highlight the differences between a digital "model", "s=
hadow" or " clone" of a system, and "digital twin". A key difference will b=
e the direction of data between the physical and virtual systems. For insta=
nce, you might state:



>>

"Typically, when using a digital twin the system is generated and then sync=
hronized using data flows in both directions between physical and digital c=
omponents, so that control data can be sent and changes between the physica=
l and digital objectives and systems are automatically represented. This be=
havior is unlike a digital model, shadow or clone, which are synchronized m=
anually,  lack control data, and will not have a full cycle of data integra=
ted."

<<



This section then launches into the discussion of the "digital twin network=
". It proposes "Key Elements of Digital Twin Network" which on my initial r=
eadthrough, read like functional components, which then leads into architec=
ture later in the document. It may be better to reorganise the document for=
 the reader to clearly state the general problem scope, then research chall=
enges and requirements not just in this document but also from other resear=
ch papers. Then you can highlight your architecture and functional componen=
ts as a way to address those research challenges.



Several journals refer to digital twin research challenges for specific ver=
tical industries (with a focus on manufacturing and healthcare), I apprecia=
te this document is focused on the telco network research, but it may be wo=
rth highlighting other research efforts as there seem to be several common =
challenges across technology areas. In addition, this document may benefit =
from a specific section on telco networking use cases, including smart citi=
es and next generation infrastructure. Then you can summarise some of the m=
ore pertinent research challenges outlined in several documents I found rel=
evant:

al twin networks. I think the document would benefit from a section on "Ena=
bling Technologies" to support the proposed architecture and functional com=
ponents. These advanced/recent technologies are related to:



- Network connectivity

- Real-time data communication, ultra-low latency and time-based networking

- Collaboration management, conflict detection and resolution

- Data privacy and integrity, trust and security



Indeed, several exciting research challenges exist for digital twin network=
ing. Still, you might also document/cite recent implementations and highlig=
ht deficiencies, and in some cases, gaps are highlighted in the implementat=
ion documentation, such as:



Digital Twins for IoT Applications: A Comprehensive Approach to Implementin=
g IoT Digital Twins

https://www.semanticscholar.org/paper/A-Comprehensive-Approach-to-Implement=
ing-IoT-Twins/5d0482cf23a52da8cf7bf8be05e1e483dc296bf0



I hope these thoughts and suggestions are helpful.

Dear NMRG,

This message starts the call for adoption as RG document for:
Digital Twin Network: Concepts and Reference Architecture - draft-zhou-nmrg=
-digitaltwin-network-concepts
https://datatracker.ietf.org/doc/draft-zhou-nmrg-digitaltwin-network-concep=
ts/<https://eur02.safelinks.protection.outlook.com/?url=3Dhttps%3A%2F%2Fdat=

ved=3D0>

Please let us know if you support or not the work becoming a RG document.
In all cases, provide detailed comments to support your opinion and send th=
em on the mailing list.
We are particularly interested in assessing the following aspects:

  1.  NMRG being a *research* group it is important to articulate well the =
problem(s), challenge(s) and research questions.
  2.  Is the scientific soundness of the draft satisfying? (quality of the =
scientific proposition, rigor of the method, impact) ; "the measure of succ=
ess is the quality and impact of the research results" [RFC2014]
  3.  As the document proposes an *architecture*, it is important to provid=
e a clear scope and positioning of this architecture with respect to networ=
k management/automation/operation frameworks and where/how the proposed arc=
hitecture will prove useful or aims at replacing/augmenting certain functio=
nality

The procedure for RG document adoption and important criteria are detailed =
here: https://mailarchive.ietf.org/arch/msg/nmrg/CVEyLUvfxJk1Ud5WdM9Y5LGvQm=

<p class=3D"MsoPlainText"><o:p>&nbsp;</o:p></p>
<p class=3D"MsoPlainText">This section feels a little light given the vario=

<p class=3D"MsoPlainText"><o:p>&nbsp;</o:p></p>
<p class=3D"MsoPlainText">4. Definition of Digital Twin Network<o:p></o:p><=
/p>
<p class=3D"MsoPlainText"><o:p>&nbsp;</o:p></p>
<p class=3D"MsoPlainText">The concept of &quot;digital twin&quot; predates =
2003 (Michael Grieves). My understanding is &quot;digital twin&quot; was in=
itially coined by NASA in the 1970s during the Apollo 13 program so that te=
rrestrial engineers could model the extra-terrestrial
 effects on&nbsp; Apollo 13 objects and systems. You might want to update y=
our etymology and add a citation, such as &quot;S. Ferguson, &quot;Apollo 1=
3: The First Digital Twin&quot;, Article by Siemens Blogs, April 14, 2020.

>&quot;<o:p></o:p></p>
<p class=3D"MsoPlainText"><o:p>&nbsp;</o:p></p>
<p class=3D"MsoPlainText">Before you define &quot;digital twin network&quot=
;, you might want to enlighten the readers about the &quot;digital twin&quo=
t; concept. This might be a definition in section 3., or a paragraph in sec=
tion 5 along the lines of:<o:p></o:p></p>
<p class=3D"MsoPlainText"><o:p>&nbsp;</o:p></p>
<p class=3D"MsoPlainText">&gt;&gt;<o:p>&nbsp;</o:p></p>
<p class=3D"MsoPlainText">&quot;A digital twin is a virtual representation =
of the real-time digital counterpart, including physical objects, systems o=
r processes. A digital twin is generated by gathering data and simulating t=
he environment so that machine learning
 reasoning may be applied, often the entire lifecycle of the object or syst=
em is also represented.&quot;<o:p></o:p></p>
<p class=3D"MsoPlainText">&lt;&lt;<o:p>&nbsp;</o:p></p>
<p class=3D"MsoPlainText"><o:p>&nbsp;</o:p></p>
<p class=3D"MsoPlainText">It may be useful to highlight the differences bet=
ween a digital &quot;model&quot;, &quot;shadow&quot; or &quot; clone&quot; =
of a system, and &quot;digital twin&quot;. A key difference will be the dir=
ection of data between the physical and virtual systems. For instance, you
 might state:<o:p></o:p></p>
<p class=3D"MsoPlainText"><o:p>&nbsp;</o:p></p>
<p class=3D"MsoPlainText">&gt;&gt;<o:p>&nbsp;</o:p></p>
<p class=3D"MsoPlainText">&quot;Typically, when using a digital twin the sy=
stem is generated and then synchronized using data flows in both directions=
 between physical and digital components, so that control data can be sent =
and changes between the physical and digital
 objectives and systems are automatically represented. This behavior is unl=
ike a digital model, shadow or clone, which are synchronized manually, &nbs=
p;lack control data, and will not have a full cycle of data integrated.&quo=
t;

<p class=3D"MsoPlainText"><o:p>&nbsp;</o:p></p>
<p class=3D"MsoPlainText">This section then launches into the discussion of=
 the &quot;digital twin network&quot;. It proposes &quot;Key Elements of Di=
gital Twin Network&quot; which on my initial readthrough, read like functio=
nal components, which then leads into architecture later
 in the document. It may be better to reorganise the document for the reade=
r to clearly state the general problem scope, then research challenges and =
requirements not just in this document but also from other research papers.=
 Then you can highlight your architecture
 and functional components as a way to address those research challenges. <=

<p class=3D"MsoPlainText">Several journals refer to digital twin research c=

research, but it may be worth highlighting
 other research efforts as there seem to be several common challenges acros=
s technology areas. In addition, this document may benefit from a specific =
section on telco networking use cases, including smart cities and next gene=

Dear Laurent, all,

After reading the draft I support its adoption as RG document.

In respect to the points you raise, here are my views:

1.       NMRG being a *research* group it is important to articulate well t=
he problem(s), challenge(s) and research questions.
This document clearly address a very relevant research topic which is the d=
efinition of network digital twin, as well as it proposes an initial archit=
ecture. In my view it is well stated, despite some aspects could be better =
clarified, as stated below when answering point 3.


2.       Is the scientific soundness of the draft satisfying? (quality of t=
he scientific proposition, rigor of the method, impact) ; "the measure of s=
uccess is the quality and impact of the research results" [RFC2014]
I think so.

3.       As the document proposes an *architecture*, it is important to pro=
vide a clear scope and positioning of this architecture with respect to net=
work management/automation/operation frameworks and where/how the proposed =
architecture will prove useful or aims at replacing/augmenting certain func=
tionality
With respect to the propose architecture, I think it is a good proposition.=
 However, I think some points need better clarification:

-          In page 5, in the first paragraph after the bullets it is mentio=
ned that it is expected the DT to control the physical network. This is als=
o reflected in the architecture figure by means of an specific control inte=
rface from the DT to the physical network. I think this control capability =
should be better explained, including scope, situations for that, etc. Is t=
his control expected to happen with/without supervision? Is it directly int=
eracting with the physical network elements, through a control element (may=
be with some associated policies), etc?

-          After Figure 2, when describing options for physical networks, a=
 number of non-IETF networks are enumerated. Not sure if we should limit th=
e scope to IETF technologies in this sense, since those are the ones that t=
he research of IRTF can influence directly.

-          When referring to base and functional models it would be nice to=
 refer to existing IETF models that could exemplify the purpose of the DT a=
rchitecture. This would help to understand the areas of future work, as wel=
l.

-          The architecture assumes a DT management entity, but the respons=
ibilities of this entity are both: (1) managing the emulated nodes and (2) =
manage the overall DT. It would be probably better to separate these two ro=
les on independent entities.

-          It is not clear if the physical network in the architecture cont=
ains both network elements and the control and managing entities acting on =
those elements. I assume yes, but some explicit statement in that respect w=
ould be beneficial.

-          The architecture assumes applications on top of the DT that coul=
d provide conventional OAM actions. This implies in my view the need of emu=
lating as well the different NMSs/SDN controllers of the physical network t=
hat could be in place since the expectation would be to have similar integr=
ation in both the DT and the physical network. Is this the expectation in t=
he draft?

Best regards,

Luis

Asunto: [nmrg] call for adoption as RG document : draft-zhou-nmrg-digitaltw=
in-network-concepts

Dear NMRG,

This message starts the call for adoption as RG document for:
Digital Twin Network: Concepts and Reference Architecture - draft-zhou-nmrg=
-digitaltwin-network-concepts
https://datatracker.ietf.org/doc/draft-zhou-nmrg-digitaltwin-network-concep=
ts/

Please let us know if you support or not the work becoming a RG document.
In all cases, provide detailed comments to support your opinion and send th=
em on the mailing list.
We are particularly interested in assessing the following aspects:
1.       NMRG being a *research* group it is important to articulate well t=
he problem(s), challenge(s) and research questions.
2.       Is the scientific soundness of the draft satisfying? (quality of t=
he scientific proposition, rigor of the method, impact) ; "the measure of s=
uccess is the quality and impact of the research results" [RFC2014]
3.       As the document proposes an *architecture*, it is important to pro=
vide a clear scope and positioning of this architecture with respect to net=
work management/automation/operation frameworks and where/how the proposed =
architecture will prove useful or aims at replacing/augmenting certain func=
tionality

The procedure for RG document adoption and important criteria are detailed =
here: https://mailarchive.ietf.org/arch/msg/nmrg/CVEyLUvfxJk1Ud5WdM9Y5LGvQm=
U

Given the time of the year, this call for adoption is open for four weeks a=
nd ends on January 7th, 2022.

Best regards, NMRG chairs

Hi all,

I support adoption of the document.  Articulation of the concepts and issue=
s behind "digital twin networks" are an important relevant topic for manage=
ment research and work item for NMRG and I would like to see the RG produce=
 a corresponding document as output.

That said, I think in its current state, the document still needs improveme=
nt in a number of areas.  I am, however, willing to the give the document a=
 benefit of a doubt as I view it as being still quite "early" and hence by =
the nature of things as somewhat immature.  For example, figure 1 has IMHO =
a key omission in that it does not depict the "original" of the twin.  Also=
, if research challenges are to be part of the document, then section 7 nee=
ds to be significantly expanded (too superficial for my taste, needs to e.g=
. elaborate more on the synchronization challenge of keeping the twins in s=
ync, on the real-time challenge given the nature of distributed systems, pr=
opagation delays, and corresponding limitations of the problem that a DT ne=
twork can address, issues and limits of emulation (and the degree to which =
you can mimic dynamic behaviors at the level of the DT) vs real-time compli=
ance assessment with models, and more.

On the research side, the idea behind DT networks is reminiscent of earlier=
 work from the 1990ies that should be referenced/acknowledged.  Examples in=
clude the Shadow MIB concept (implemented eg in the OSIMIS platform at the =
time), in which a representation of the network in a management platform wa=
s acted on by by applications, with active objects being responsible for th=
eir synchronization, similarly Inductive Modeling Technique (as implemented=
 by Cabletron Spectrum at the time), presumably also references from the th=
e TMN and ISO/OSI management arena.

With that, responses to the questions inline, <ALEX>

Subject: [nmrg] call for adoption as RG document : draft-zhou-nmrg-digitalt=

Dear NMRG,

This message starts the call for adoption as RG document for:
Digital Twin Network: Concepts and Reference Architecture - draft-zhou-nmrg=
-digitaltwin-network-concepts
https://datatracker.ietf.org/doc/draft-zhou-nmrg-digitaltwin-network-concep=
ts/<https://nam11.safelinks.protection.outlook.com/?url=3Dhttps%3A%2F%2Fdat=

d=3D0>

Please let us know if you support or not the work becoming a RG document.
<ALEX> Yes, I support </ALEX>
In all cases, provide detailed comments to support your opinion and send th=
em on the mailing list.
We are particularly interested in assessing the following aspects:

  1.  NMRG being a *research* group it is important to articulate well the =
problem(s), challenge(s) and research questions.
<ALEX> If it is to address research questions, this should probably be refl=
ected in title or abstract.  The topic is certainly relevant for research a=
nd IMHO appropriate for NMRG to tackle. </ALEX>

  1.  Is the scientific soundness of the draft satisfying? (quality of the =
scientific proposition, rigor of the method, impact) ; "the measure of succ=
ess is the quality and impact of the research results" [RFC2014]
<ALEX> As mentioned earlier, references to previous work need to be expande=
d on.  Section 7, which discusses key challenges, is at the moment still un=
derdeveloped and will need to be significantly expanded. </ALEX>

  1.  As the document proposes an *architecture*, it is important to provid=
e a clear scope and positioning of this architecture with respect to networ=
k management/automation/operation frameworks and where/how the proposed arc=
hitecture will prove useful or aims at replacing/augmenting certain functio=
nality
<ALEX> I think the architecture that is described is clear enough, will be =
useful, and provides a sufficient basis for going forward.</ALEX>

The procedure for RG document adoption and important criteria are detailed =
here: https://mailarchive.ietf.org/arch/msg/nmrg/CVEyLUvfxJk1Ud5WdM9Y5LGvQm=

Given the time of the year, this call for adoption is open for four weeks a=
nd ends on January 7th, 2022.

Best regards, NMRG chairs

Hi all,

I support adoption of the document.  Articulation of the concepts and =
issues behind =E2=80=9Cdigital twin networks=E2=80=9D are an important =
relevant topic for management research and work item for NMRG and I =
would like to see the RG produce a corresponding document as output. =20

That said, I think in its current state, the document still needs =
improvement in a number of areas.  I am, however, willing to the give =
the document a benefit of a doubt as I view it as being still quite =
=E2=80=9Cearly=E2=80=9D and hence by the nature of things as somewhat =
immature.  For example, figure 1 has IMHO a key omission in that it does =
not depict the =E2=80=9Coriginal=E2=80=9D of the twin.  Also, if =
research challenges are to be part of the document, then section 7 needs =
to be significantly expanded (too superficial for my taste, needs to =
e.g. elaborate more on the synchronization challenge of keeping the =
twins in sync, on the real-time challenge given the nature of =
distributed systems, propagation delays, and corresponding limitations =
of the problem that a DT network can address, issues and limits of =

<Authors> Accept your suggestion. We will revise the draft in next =
version via 1) describing more on the =E2=80=98original=E2=80=99 of the =
twin, and 2) expending research challenges.=20

On the research side, the idea behind DT networks is reminiscent of =

Please let us know if you support or not the work becoming a RG =

<ALEX> Yes, I support </ALEX>

In all cases, provide detailed comments to support your opinion and send =
them on the mailing list.

We are particularly interested in assessing the following aspects:

1.      NMRG being a *research* group it is important to articulate well =
the problem(s), challenge(s) and research questions.=20

<ALEX> If it is to address research questions, this should probably be =

<Authors> Accept your suggestion and will revise in next version.

the scientific proposition, rigor of the method, impact) ; =E2=80=9Cthe =
measure of success is the quality and impact of the research =
results=E2=80=9D [RFC2014]

<ALEX> As mentioned earlier, references to previous work need to be =
expanded on.  Section 7, which discusses key challenges, is at the =
moment still underdeveloped and will need to be significantly expanded. =
</ALEX>

<Authors> Accept your suggestion and will revise in next version.

3.      As the document proposes an *architecture*, it is important to =
provide a clear scope and positioning of this architecture with respect =
to network management/automation/operation frameworks and where/how the =
proposed architecture will prove useful or aims at replacing/augmenting =

<ALEX> I think the architecture that is described is clear enough, will =
