*** Paper submission deadline: July 19, 2021 ***

The  12th  International Conference on  Network of the Future (NoF) is  
inviting
authors to submit original contributions  in the area of Future Internet 
design,
with emphasis on enabling and cutting-edge technologies from the 
perspectives of
specification,  design and  analysis related to  network of future 
architecture,
applications, services,  management, scalability, standardization, 
business and
legal aspects, just to name a few.

NoF 2021 Demo Sessions aims at offering  a venue for the latest 
breakthroughs in
the topics of interest of NoF 2021  to be presented live and discussed 
with the
audience.  Demos ranging from working prototypes, novel applications and 
ground-
breaking ideas to live experiments in the areas shaping future networks 
are wel-
come. We also encourage demos from industrial researchers.

The  conference  aims  at  providing  a  forum  for  researchers, 
students, and
professionals  to  exchange ideas,  share  their experiences,  and 
discuss their
research results  around a single-track  of technical sessions and a 
series  of
keynote speeches.

NoF 2021 will take place at the University of Coimbra in Portugal.

The  conference  will  be  designed  and prepared  as a  hybrid event  
allowing
registrants the choice to participate either virtually or in-person. In 
the case
of perduring traveling restrictions (official or de facto) during the 
conference
dates due  to the COVID-19 pandemic, we will  be ready to convert the 
conference
to a fully on-line event.

Dear all,

I would like to thank you all for proposing your help to lead some challenges and 
providing inputs in the doc.
Note that I've now created a third version of the document: 
https://docs.google.com/document/d/1I9Z3MiwqdY_CkQI5yWpyKRTvIYjeDqWM5fDIZQ_K63o/edit

It reflects the discussion by emails and during meetings.
Lead editors have been partially identified in bold fonts (some needs to be confirmed)

We start now phase 2 dedicated to collectively write the two selected challenges 
as examples. I suggest the following ones:
- #2 data management
- #9 AI for planning of actions

*T**he deadline is July 18. I ask every contributor to provide their inputs and 
the lead editor to monitor and consolidate them according to the generic template 
we defined in the last meeting:*
- Motivation
--> Highlight the criticality/impact of the problem to be addressed
- Current SotA
--> current proposals / trends based on reference/survey
- Detailed description of the sub(challenges)
-->Highlight what are the remaining issues to be resolved from the previous SotA

*I would like also to propose a tentative editorial meeting focused on these two 
challenges to finalize them the week before IETF. Please fill out the following 
doodle by July 9:*

    Dear all,<br>
    <br>
    I would like to thank you all for proposing your help to lead some
    challenges and providing inputs in the doc.<br>
    Note that I've now created a third version of the document:
<a class="moz-txt-link-freetext" href="https://docs.google.com/document/d/1I9Z3MiwqdY_CkQI5yWpyKRTvIYjeDqWM5fDIZQ_K63o/edit">https://docs.google.com/document/d/1I9Z3MiwqdY_CkQI5yWpyKRTvIYjeDqWM5fDIZQ_K63o/edit</a><br>
    <br>
    It reflects the discussion by emails and during meetings. <br>
    Lead editors have been partially identified in bold fonts (some
    needs to be confirmed)<br>
    <br>
    We start now phase 2 dedicated to collectively write the two
    selected challenges as examples. I suggest the following ones:<br>
    - #2 data management<br>
    - #9 AI for planning of actions <br>
    <br>
    <b>T</b><b>he deadline is July 18. I ask every contributor to
      provide their inputs and the lead editor to monitor and
      consolidate them according to the generic template we defined in
      the last meeting:</b><br>
    - Motivation<br>
    --&gt; Highlight the criticality/impact of the problem to be
    addressed<br>
    - Current SotA<br>
    --&gt; current proposals / trends based on reference/survey<br>
    - Detailed description of the sub(challenges)<br>
    --&gt;Highlight what are the remaining issues to be resolved from
    the previous SotA<br>
    <br>
    <b>I would like also to propose a tentative editorial meeting
      focused on these two challenges to finalize them the week before
      IETF. Please fill out the following doodle by July 9:</b><br>
    <br>

      <br>
      To progress on the document we agree to target the following
      timeline:<br>
      <br>
      <b>1) June 30<br>
      </b>- List of challenges identified<b><br>
      </b>- One lead editor per challenge identified<br>
      <br>
      <br>
      <b>2) July 18</b><br>
      Writing of one or two challenges as example(s) based on the
      template (see the slides: <a class="moz-txt-link-freetext"
href="https://docs.google.com/presentation/d/1FH4M884mHXdr2WrZZ3UTcuxlIxUV4mXE/edit#slide=id.ge19cc74927_0_58"

      (They will be identified after June 30)<br>
      <br>
      <b>3) September 07</b><br>
      All challenges written according to the template with an
      equivalent level of details of the examples<br>
      Introduction refined according to current comments (Jerome)<br>
      <br>
      <br>
      <b>For point 1):</b><br>
      - the list of challenges must be frozen for our first iteration
      (challenges could be added later if needed)<br>
      - The current challenge (<a class="moz-txt-link-freetext"
href="https://docs.google.com/document/d/1dQOzZustI2mkYr_omtiqu3FqUvoqLgaCp7nbRj4ZJyw/edit"
        moz-do-not-send="true">https://docs.google.com/document/d/1dQOzZustI2mkYr_omtiqu3FqUvoqLgaCp7nbRj4ZJyw/edit</a>)
      list will be kept with the following modifications:<br>
      -- "#2 data" merged with "#13 Scalable real-time monitoring"<br>
      -- "#9 AI for Intent-based management " to be reshaped as AI for
      planning actions in NM (not specific to IBN)<br>
      -- "#8 ML for Intent based management": must not be specific to
      IBN. Maybe to be merged "#10 AI for Exploiting External Events"
      under a challenge related to the use of non technical/external
      data but we would like to have more feedback here.<br>
      <br>
      Of course, this represents the outcome of the discussion we had
      during the meeting but please do not hesistate to provide <b>any
        feedback until June 30.<br>
        <br>
      </b> <b>Besides, please let me know by June 30 if you are willing
        to be the lead editor for a challenge.</b><b><br>
      </b><b> Anybody can contribute to any challenge but the role of
        the lead editor would be to integrate the different
        comments/modifications proposed.</b><b><br>

Hello, experts in NMRG,=20

We just submitted a new version of I-D =
draft-zhou-nmrg-digitaltwin-network-concepts-04.txt.=20
The main changed in the version are listed as below.=20
 1)  Changed the I-D title from "Concepts of Digital Twin Network" to =
"Digital Twin Network: Concepts and Reference Architecture".
 2)  Update data definition and models definitions to clarify their =
difference.
 3)  Remove the orchestration element and consolidated into control =
functionality building block in the digital twin network.
 4)  Clarify the mapping relation (one to one, and one to many) in the =
mapping definition.
 5)  Add explanation text for continuous verification.

We would appreciate any thoughts or comments on this I-D from the group.

Thanks and Best Regards,
Cheng Zhou (on behalf of co-authors)

Abstract:
   Digital Twin technology has been seen as a rapid adoption technology
   in Industry 4.0.  The application of Digital Twin technology in the
   networking field is meant to realize efficient and intelligent
   management and accelerate network innovation.  This document presents
   an overview of the concepts of Digital Twin Network (DTN), provides
   the definition and reference architecture, application scenarios, and
   then describes the benefits and key challenges of such technology.

                                                                         =

Internet-Draft        Digital Twin Network Concept             July 2021=0A=
=0A=
=0A=
1.  Introduction=0A=
=0A=
   With the advent of technologies such as 5G, Industrial Internet of=0A=
   Things, Edge Computing, and Artificial Intelligence, the ICT=0A=
   (Information and Communications Technology) and other vertical=0A=
   industries such as smart cities or smart manufacturers are=0A=
   transformed dramatically through replacing what is used to be manual=0A=
   processes with digital processes.=0A=
=0A=
   With the fast growing of the network scale and the increased demand=0A=
   placed on the network, accommodating and adapting dynamically to=0A=
   customer needs becomes a big challenge to network operators.  Indeed,=0A=
   network operation and maintenance are becoming more complex due to=0A=
   higher complexity of the managed networks.  As such, providing=0A=
   innovations on network will be more and more difficult due to the=0A=
   high risk of interfering with existing services and higher trial cost=0A=
   if no reliable emulation platforms are available.=0A=
=0A=
   Digital Twin is the real-time representation of physical entities in=0A=
   the digital world.  It has the characteristics of virtual-reality=0A=
   interrelation and real-time interaction, iterative operation and=0A=
   process optimization, as well as full life-cycle, and full business=0A=
   data-driven.  So far, it has been successfully applied in the fields=0A=
   of intelligent manufacturing, smart city, or complex system operation=0A=
   and maintenance [Tao2019] to help with not only object design and=0A=
   testing, but also operation and maintenance.=0A=
=0A=
   A digital twin network platform can be built by applying Digital Twin=0A=
   technology to networks and creating a virtual image of physical=0A=
   network facilities (emulation).  Through the real-time data=0A=
   interaction between the physical network and its twin network, the=0A=
   digital twin network platform might help the network designers to=0A=
   achieve more simplification, automatic, resilient, and full life-=0A=
   cycle operation and maintenance.  Having an emulation platform that=0A=
   allows to reliably represent the state of a network is more reliable=0A=
   than a simulation platform.  The emulated platform can thus be used=0A=
   to assess specific behaviors before actual implementation in the=0A=
   physical network, tweak the network for better optimized behavior,=0A=
   run 'what-if' scenarios that can't be tested and evaluated easily in=0A=
   the physical network.  Service impact analysis tasks will also be=0A=
   facilitated.=0A=

4.  Definition of Digital Twin Network=0A=
=0A=
   The concept of a virtual equivalent to a physical product or the=0A=
   digital twin was first introduced in the Product Lifecycle Management=0A=
   (PLM) course in 2003 by Scholar Michael Grieves [Grieves2014].  It=0A=
   has been widely acknowledged in both industry and academic=0A=
   publications.  However, there is no standard definition of "digital=0A=
   twin network" within the networking industry or SDOs.  This document=0A=
   defines digital twin network as a virtual representation of the=0A=
   physical network.  Such virtual representation of the network is=0A=
   meant to be used to analyze, diagnose, emulate, and then control the=0A=
   physical network based on data, model and interface.  To that aim, a=0A=
   real-time and interactive mapping is required between the physical=0A=
   network and its virtual twin network.=0A=
=0A=
   As shown in Figure 1, the digital twin network involve four key=0A=
   technology elements: data, mapping, models, and interfaces=0A=

   Data:  A digital twin network should maintain historical data and/or=0A=
      real time data (configuration data, operational state data,=0A=
      topology data, trace data, metric data, process data, etc.) about=0A=
      its real-world twin (i.e., physical network) that are required by=0A=
      the models to represent and understand the states and behaviors of=0A=
      the real-world twin.  The data is characterized as the single=0A=
      source of the "truth" and populated in the data repository, which=0A=
      provides timely and accurate data service support for building=0A=
      various models..=0A=
=0A=
   Models:  Techniques that involve collecting data from one or more=0A=
      sources in the real-world twin and developing a comprehensive=0A=
      representation of the data (e.g., system, entity, process) using=0A=
      specific models.  It is used as emulation and diagnosis basis to=0A=
      provides dynamics and elements on how live physical network=0A=
      operates and develop reasoning data utilized for decision-making.=0A=
      Various models such as service models, data models, dataset=0A=
      models, or knowledge graph can be used to represent the physical=0A=
      network assets and then instantiated to serve various network=0A=
      applications.=0A=
=0A=
   Interfaces:  Standardized interfaces can ensure the compatibility of=0A=
      digital twin network.  There are two major types of interface: (1)=0A=
      the interface between the digital twin network platform and the=0A=
      physical network infrastructure and (2) the interface between=0A=
      digital twin network platform and applications.  The former=0A=
      provides real time data collection and control on the physical=0A=
      network; the latter helps deliver application requirements to=0A=

      to applications.=0A=
=0A=
   Mapping:  Is used to identify the digital twin and the underlying=0A=
      entities and establish a real-time interactive mapping between the=0A=
      physical network and the twin network or between two twin=0A=
      networks.  The mapping can be:=0A=
=0A=
      *  One to one (pairing, vertical): Synchronize between a physical=0A=
         network and its virtual twin network with continuous flow.=0A=
=0A=
      *  One to many (coupling, horizontal): Synchronize among virtual=0A=
         twin networks with occasional data exchange.=0A=
=0A=
      Such mapping provides a good visibility of actual status which=0A=
      makes it more convenient to analyze and understand what is going=0A=
      on in the physical network.  It also allows using the digital twin=0A=
      to optimize the performance and maintenance of the physical=0A=
      network.=0A=
=0A=
   The digital twin network constructed based on the four core=0A=
   technology elements can analyze, diagnose, emulate, and control the=0A=
   physical network in the whole life cycle with the help of=0A=
   optimization algorithms, management methods, and expert knowledge.=0A=
   One of the objectives of such control is to master the digital twin=0A=
   network environment and its elements to derive the required system=0A=
   behavior, e.g., provide:=0A=
=0A=
   o  repeatability: that is the capacity to replicate network=0A=
      conditions on-demand.=0A=
=0A=
   o  reproducibility: i.e., the ability to replay successions of=0A=
      events, possibly under controlled variations.=0A=
=0A=
5.  Benefits of Digital Twin Network=0A=
=0A=
   Digital twin network can help enable closed-loop network management=0A=
   across the entire lifecycle, from deployment and emulation, to=0A=
   visualized assessment, physical deployment, and continuous=0A=
   verification.  In doing so, network operators (and end-users to some=0A=
   extent) can get a global, systemic, and consistent view of the=0A=
   network.  Also, network operators can safely exercise the enforcement=0A=
   of network planning policies, deployment procedures, etc., without=0A=
   jeopardizing the daily operation of the physical network.=0A=
=0A=
   The benefits of digital twin network can be classified into: low cost=0A=
   of network optimization, optimized and safer decision-making, safer=0A=
   testing of innovative network capabilities (including "what if"=0A=

   scenarios), privacy and regulatory compliance, and customize network=0A=
   operation training.  The following subsections further elaborate on=0A=
   such benefits.=0A=
=0A=
5.1.  Lower the Cost of Network Optimization=0A=
=0A=
   Large scale networks are complex to operate.  Since there is no=0A=
   effective platform for simulation, network optimization designs have=0A=
   to be tested on the physical network at the cost of jeopardizing its=0A=
   daily operation and possibly degrading the quality of the services=0A=
   supported by the network.  Such assessment greatly increases network=0A=
   operator's Operational Expenditure (OPEX) budgets too.=0A=
=0A=
   With a digital twin network platform, network operators can safely=0A=
   emulate candidate optimization solutions before deploying them in the=0A=
   physical network.  In addition, the operator's OPEX on the real=0A=
   physical network deployment will be greatly decreased accordingly at=0A=
   the cost of the complexity of the assessment and the resources=0A=
   involved.=0A=
=0A=
5.2.  Optimized Decision Making=0A=
=0A=
   Traditional network operation and management mainly focus on=0A=
   deploying and managing running services, but hardly support=0A=
   predictive maintenance techniques.=0A=
=0A=
   Digital twin network can combine data acquisition, big data=0A=
   processing, and AI modeling to assess the status of the network, but=0A=
   also to predict future trends, and better organize predictive=0A=
   maintenance.  The ability to reproduce network behaviors under=0A=
   various conditions facilitates the corresponding assessment of the=0A=
   various evolution options as often as required.=0A=
=0A=
5.3.  Safer Assessment of Innovative Network Capabilities=0A=
=0A=
   Testing a new feature in an operational network is not only complex,=0A=
   it is also extremely risky.=0A=
=0A=
   As mentioned above, digital twin network can greatly help assessing=0A=
   innovative network capabilities without jeopardizing the daily=0A=
   operation of the physical network.  In addition, it also helps=0A=
   researchers to explore network innovation (e.g., new network=0A=
   protocols, network AI/ML applications) efficiently, and network=0A=
   operators to deploy new technologies quickly with lower risks.  Take=0A=
   AI/ ML application as example, it is a conflict between the=0A=
   continuous high reliability requirement (i.e., 99.999%) of network=0A=
   and the slow learning speed or phase-in learning steps of AI/ML=0A=
   algorithms.  With digital twin network platform, AI/ML can complete=0A=

   the learning and training with the sufficient data before deploying=0A=
   the model in the real network.  This will greatly encourage more=0A=
   network AI innovations in future networks.=0A=
=0A=
5.4.  Privacy and Regulatory Compliance=0A=
=0A=
   The requirements on data confidentiality and privacy on network=0A=
   providers increase the complexity of network management, as decisions=0A=
   made by computation logics such as an SDN controller may rely upon=0A=
   the payloads content.  As a result, the improvement of data-driven=0A=
   management requires complementary techniques that can provide a=0A=
   strict control based upon security mechanisms to guarantee data=0A=
   privacy protection and regulatory compliance.  Some examples of these=0A=
   techniques include payload inspection, including decryption with user=0A=
   explicit consents, or data anonymization mechanisms.=0A=
=0A=
   Given digital twin network operation assumes the mapping between real=0A=
   traffic or services and the traffic used by the digital twin network=0A=
   for assessment purposes in particular, the need for privacy is of the=0A=
   utmost importance.  The lack of personal data permits to lower the=0A=
   privacy requirements and simplifies the use of privacy-preserving=0A=
   techniques.=0A=
=0A=
5.5.  Customize Network Operation Training=0A=
=0A=
   Network architectures can be complex, and their operation requires=0A=
   expert personnel.  Digital twin network offers an opportunity to=0A=
   train staff for customized networks and specific user needs.  Two=0A=
   salient examples are the application of new network architectures and=0A=
   protocols or the use of cyber-ranges to train security experts in the=0A=
   threat detection and mitigation.=0A=
=0A=
6.  Reference Architecture of Digital Twin Network=0A=
=0A=
   Based on the definition of the key digital twin network technology=0A=
   elements introduced in Section 4, a digital twin network architecture=0A=
   is depicted in Figure 2.  The digital twin network architecture is=0A=

   1.  The lowest layer is the Physical Network.  (All) network elements=0A=
       in the physical network exchange massive network data and control=0A=
       with network digital twin entity, through twin southbound=0A=
       interfaces.  As the physical object of the network twin, the=0A=
       physical network can be a mobile access network, a transport=0A=
       network, a mobile core, a backbone, etc.  The network can also be=0A=
       a data center network, a campus enterprise network, an industrial=0A=
       Internet of Things, etc.  The network can span across a single=0A=
       network domain or multiple network domains.=0A=

             characterization of the physical network.=0A=
=0A=
          +  Functional models refer to various data models such as=0A=
             network analysis, simulation, diagnosis, prediction,=0A=
             assurance, etc.  The functional models can be constructed=0A=
             and expanded by multiple dimensions: by network type, there=0A=
             can be models serving for a single or multiple network=0A=

7.  Challenges to build Digital Twin Network=0A=
=0A=
   As mentioned in the above section, digital twin networks can bring=0A=
   many benefits to network management as well as facilitate the=0A=
   introduction of innovative network capabilities.  However, building=0A=
   an effective and efficient digital twin network system remains a=0A=
   challenge.  The following is a list of the major challenges:=0A=
=0A=
   o  Large scale challenge: The digital twin of large-scale networks=0A=
      will significantly increase the complexity of data acquisition and=0A=
      storage, the design and implementation of models.  And the=0A=
      requirements of software and hardware of the system will be even=0A=
      more constraining.=0A=
=0A=
   o  Interoperability: It is difficult to establish a unified digital=0A=
      twin platform with a unified data model in the whole network=0A=
      domain due to the inconsistency of technical implementations and=0A=
      the heterogeneity of vendor technologies.=0A=
=0A=
   o  Data modeling difficulties: Based on large-scale network data,=0A=
      data modeling should not only focus on ensuring the accuracy of=0A=
      model functions, but also need to consider the flexibility and=0A=
      scalability of the model.  Balancing these requirements further=0A=
      increase the complexity of building efficient and hierarchical=0A=
      functional data models.=0A=
=0A=
   o  Real-time requirement: For services with real-time requirements,=0A=
      the processing of model simulation and verification through a=0A=
      digital twin network will increase the service delay, so the=0A=
      function and process of the data model need to be based on=0A=
      automated processing mechanism under various network application=0A=
      scenarios; at the same time, the real-time requirements will=0A=
      further increase performance requirements on the system software=0A=
      and hardware.=0A=
=0A=
   o  Security risks: the digital twin network synchronizes all the data=0A=
      of physical networks in real time, which inevitably augments the=0A=
      attack surface, with a higher risk of information leakage, in=0A=
      particular.=0A=
=0A=
   To address these challenges, the digital twin network needs=0A=
   continuous optimization and breakthrough on key enabling technologies=0A=
   including data acquisition, data storage, data modeling, network=0A=
   visualization, interface standardization, and security assurance, so=0A=
   as to meet the requirements of compatibility, reliability, real-time=0A=
   and security.=0A=

=0A=
=0A=
8.  Interaction with IBN=0A=
=0A=
   Implementing Intent-Based Networking (IBN) is an innovative=0A=
   technology for life-cycle network management.  Future network will be=0A=
   possibly Intent-based, which means that users can input their=0A=
   abstract 'intent' to the network, instead of detailed policies or=0A=
   configurations on the network devices.=0A=
   [I-D.irtf-nmrg-ibn-concepts-definitions] clarifies the concept of=0A=
   "Intent" and provides an overview of IBN functionalities.  The key=0A=
   characteristic of an IBN system is that user's intent can be assured=0A=
   automatically via continuously adjusting the policies and validating=0A=
   the real-time situation.=0A=
=0A=
   IBN can envisaged in a digital twin network context to show how=0A=
   digital twin network improves the efficiency of deploying network=0A=
   innovation.  To lower the impact on real networks, several rounds of=0A=
   adjustment and validation can be emulated on the digital twin network=0A=
   platform instead of directly on physical network.  Therefore, digital=0A=
   twin network can be an important enabler platform to implement IBN=0A=
   system and speed up the deployment of IBN in customer's network.=0A=
=0A=
9.  Application Scenarios=0A=
=0A=
   Digital twin network can be applied to solve different problems in=0A=
   network management and operation.=0A=
=0A=
9.1.  Human Training=0A=
=0A=
   The usual approach to network Operations, Administration, and=0A=
   Maintenance (OAM) with procedures applied by humans is open to errors=0A=
   in all these procedures, with impact in network availability and=0A=
   resilience.  Response procedures and actions for most relevant=0A=
   operational requests and incidents are commonly defined to reduce=0A=
   errors to a minimum.  The progressive automation of these procedures,=0A=
   such as predictive control or closed loop management, reduce the=0A=
   faults and response time, but still there is the need of a human-in-=0A=
   the-loop for multiples actions.  These processes are not intuitive=0A=
   and require training to learn how to respond.=0A=
=0A=
   The use of digital twin network for this purpose in different network=0A=
   management activities will improve the operators performance.  One=0A=
   common example is cybersecurity incident handling, where cyber-range=0A=
   exercises are executed periodically to train security practitioners.=0A=
   Digital twin network will offer realistic environments, fitted to the=0A=
   real production networks.=0A=

=0A=
=0A=
9.2.  ML Training=0A=
=0A=
   Machine Learning requires data and their context to be available in=0A=
   order to apply it.  A common approach in the network management=0A=
   environment has been to simulate or import data in a specific=0A=
   environment (the ML developer lab), where they are used to train the=0A=
   selected model, while later, when the model is deployed in=0A=
   production, re-train or adjust to the production environment context.=0A=
   This demands a specific adaption period.=0A=
=0A=
   Digital twin network simplifies the complete ML lifecycle development=0A=
   by providing a realistic environment, including network topologies,=0A=
   to generate the data required in a well-aligned context.  Dataset=0A=
   generated belongs to the digital twin network and not to the=0A=
   production network, allowing information access by third parties,=0A=
   without impacting data privacy.=0A=
=0A=
9.3.  DevOps-oriented certification=0A=
=0A=
   The potential application of CI/CD models network management=0A=
   operations increases the risk associated to deployment of non-=0A=
   validated updates, what conflicts with the goal of the certification=0A=
   requirements applied by network service providers.  A solution for=0A=
   addressing these certification requirements is to verify the specific=0A=
   impacts of updates on service assurance and SLAs using a digital twin=0A=
   network environment replicating the network particularities, as a=0A=
   previous step to production release.=0A=
=0A=
   Digital twin network control functional block supports such dynamic=0A=
   mechanisms required by DevOps procedures.=0A=
=0A=
9.4.  Network fuzzing=0A=
=0A=
   Network management dependency on programmability increases systems=0A=
   complexity.  The behavior of new protocol stacks, API parameters, and=0A=
   interactions among complex software components are examples that=0A=
   imply higher risk to errors or vulnerabilities in software and=0A=
   configuration.=0A=
=0A=
   Digital twin network allows to apply fuzzing testing techniques on a=0A=
   twin network environment, with interactions and conditions similar to=0A=
   the production network, permitting to identify and solve=0A=
   vulnerabilities, bugs and zero-days attacks before production=0A=

10.  Summary=0A=
=0A=
   Research on digital twin network has just started.  This document=0A=
   presents an overview of the digital twin network concepts.  Looking=0A=
   forward, further elaboration on digital twin network scenarios,=0A=
   requirements, architecture, and key enabling technologies should be=0A=
   promoted by the industry, so as to accelerate the implementation and=0A=
   deployment of digital twin network.=0A=
=0A=
11.  Security Considerations=0A=
=0A=
   This document describes concepts and definitions of digital twin=0A=
   network.  As such, the below security considerations remain high=0A=
   level, i.e., in the form of principles, guidelines or requirements.=0A=
=0A=
   Security considerations of the digital twin network include:=0A=
=0A=
   o  Secure the digital twin system itself.=0A=
=0A=
   o  Data privacy protection.=0A=
=0A=
   Securing the digital twin network system aims at making the digital=0A=
   twin system operationally secure by implementing security mechanisms=0A=
   and applying security best practices.  In the context of digital twin=0A=
   network, such mechanisms and practices may consist in data=0A=
   verification and model validation, mapping operations between=0A=
   physical network and digital counterpart network by authenticated and=0A=
   authorized users only.=0A=
=0A=
   Synchronizing the data between the physical and the digital twin=0A=
   networks may increase the risk of sensitive data and information=0A=
   leakage.  Strict control and security mechanisms must be provided and=0A=
   enabled to prevent data leaks.=0A=

Dear Cheng,

The overall proposal in this I-D is an enlarged version of a typical
closed-cycle autonomic network management architecture. It has been
enlarged by instantiating a simulator together with the model building
and other elements of the analysis stage and knowledge base. Moreover,
it has increased requirements for input data, so that both models and
simulators have a more realistic view of the network. Because of this I
find the document lacks a mapping of the reference architecture and the
typical network management architecture, both abstract, in terms of, for
instance, MAPE loop, as well as an implementation, as Open Source MANO.

   3rd International Workshop on High-Precision, Predictable,    =20
            and Low-Latency Networking (HiPNet 2021)

Call for Papers

New waves  of networked  applications continue to  push the  limits of
what is possible with networks today. For example, Industrial Internet
applications,  Augmented Reality,  Tactile Internet  require ultra-low
latency measured in  single-digit milliseconds and do  not tolerate no
jitter at all. Economic  pressures mandate increasingly cloudification
of real-time applications with precision  service level needs. Many of
those applications are mission-critical and  cannot afford any loss in
connectivity or even single  packets. Collectively, these applications
require   networking   services   that  support   high-precision   and
predictable service  levels with associated guarantees  that border on
determinism.  This requires  a rethinking  of many  of the  principles
underlying existing "Best Effort" internetworking technology.

Various  approaches  are emerging  to  tackle  those challenges.  Data
centers with  fixed topologies and  a constant number of  hops rapidly
replace    conventional   routing    and    more   general    Internet
topologies.  Networks  are  becoming  more programmable  to  allow  to
custom-tailor  and optimize  treatment of  packets and  flows. Related
technologies range  from Service Function Chaining  to Network Slicing
to  SDN.  While  5G is  making URLLC  at the  network edge  a reality,
momentum for  Beyond 5G and 6G  is building to push  the boundaries of
precision  services  beyond  the  edge   and  across  the  core.   One
overarching question concerns how  these technologies can be harnessed
and what additional approaches are needed to deliver on high-precision
and predictable networking. This will involve advances over all planes
of  network  architectures,  such  as programming  and  processing  of
packets in  the data plane,  control interfaces and  ultra-low latency
control  loops  to  optimize  service  levels  in  the  control-plane,
high-precision measurements and telemetry  with nanosecond accuracy at
scale, and related platforms and algorithms in the management plane.

The workshop  aims to  provide a forum  for researchers,  students and
professionals  from  industry  and  academia  to  discuss  challenges,
solution  approaches, and  work-in-progress  to  deliver, manage,  and
control high-precision and  predictable networking services, including
(Ultra) Low-Latency  networks, deterministic networking, 6G,  etc. The
workshop welcomes  papers related  to disruptive  concepts, innovative
solutions, testbeds, experiments, etc.  Topics of Interest include but
are not limited to the following:

- Platforms  to   manage  and  operate  high-precision   networks  and
services,  e.g.  Industrial  Networks, Tactile  Networks,  Augmented
Reality (AR), cloud gaming
- Proof and validation of high-precision service level guarantees
- High-precision  measurement  techniques  for ultra-low  latency  and
jitter
- Service assurance for micro services, for service function chains
- Applications for Inband Network Telemetry and iOAM
- High-precision networking using service function chaining
- In-network service level tuning and optimization; predictable QoS
- Novel network programming models
- Applications   of   Artificial   Intelligence   for   high-precision
networking
- Time-Sensitive Networking  (TSN) interconnect and wide-area  TSN; IP
and TSN convergence
- SDN applications for high-precision, high-performance networking
- High-precision networking over 5G
- High-Precision networking services using Fog and Edge Computing
- Deployment & operational experiences w/ Industrial Internet, Tactile
Internet, networked AR, cloud gaming
- 5G optimization techniques for ensuring Low Latency
- Testbeds for High-Precision (OAI, MAGMA, etc.)
- Networking  optimization for  fast  processing  and delivery  (DPDK,
etc.)
- Microservices platform for ensuring High-Precision (OpenNetVM, etc.)

***************************************************************************=
******
As we are heading towards nascent 6G networks, this is the appropriate time=
 to do a hindsight exercise to gather the lessons learned to start shaping =
the networks to come in a coherent and converged manner towards a service-o=
riented automatically managed network. The adoption of virtualization and s=
oftwarization for networks and ICT infrastructures in general is more than =
ever an opportunity of moving network solutions to customized end-to-end, y=
et private and independent, network services designed and delivered on-dema=
nd over heterogeneous network segments and infrastructures. The ever-growin=
g connectivity demand and continually more stringent performance requiremen=
ts along with operational and environmental costs are pushing the boundarie=
s of network solutions to maximize the efficiency of every deployment and o=
peration action.

In this direction, automation and its extreme form known as "zero-touch" ha=
s drawn the attention of many actors from the IT, Telecom and Cloud sectors=
. A plethora of initiatives dealing with all related aspects from a global =
or specialized point of view for 5G and beyond networks can be cited here: =
TMF ZOOM, ETSI ZSM, ETSI ENI, RAN-related management initiatives (O-RAN, ON=
F SD-RAN), different EU and non-EU research projects like MON-B5G, 5G-DIVE,=
 5Growth, 5GZORRO, INSPIRE5Gplus, and last but not least the Hexa-X project=
 recently launched as a flagship 6G European initiative.

An important objective of zero-touch is to go beyond the use of software-ba=
sed solutions to automate some well-understood tasks for the sake of time s=
avings. Zero-touch considers to make full use of analytics and AI-based mod=
els to perform decision making at all levels of operations: optimize resour=
ce sharing, reduce consumption using flexible mechanisms for network servic=
e provisioning, and support new deployment models adapted to massively dist=
ributed infrastructures, while ensuring smooth service continuity, SLA-comp=
liance and end-to-end automation of the management and orchestration of net=
work services and resources. Automation brings a series of challenges to th=
e ways in which network services and more generally network slices are desi=
gned, deployed, provided and (intelligently) managed. Multiple issues are s=
till to be addressed for zero-touch to be concretely adopted by the Industr=
y. One important direction is the need to converge on the way societal stim=
uli coming in the form of service requests from a variety of vertical indus=
tries (e.g., industry 4.0, transportation, energy, automotive, eHealth) are=
 handled by the network. And it is not only about dynamically deploying the=
 service, but most importantly about continuously monitoring it and providi=
ng the various control loops towards 24/7 operation whilst fulfilling SLA r=
equirements. This is the point at which the network will become a catalyzer=
 of all sorts of economic activity of our society, at the level of what the=
 Internet represented half a century ago.

Therefore, with the same spirit of CNSM as a whole, this workshop on "Zero-=
touch Network and Service Management" (ZNSM) aims at providing an internati=
onal forum for researchers and practitioners from academia and the industry=
 at large, including network operators, service providers, equipment manufa=
cturers and IT companies, to discuss and address the challenges deriving fr=
om such evolution in the delivery and operation of networks and services.

***************************************************************************=
*******

Dear Cheng,

The overall proposal in this I-D is an enlarged version of a typical
closed-cycle autonomic network management architecture. It has been
enlarged by instantiating a simulator together with the model building
and other elements of the analysis stage and knowledge base. Moreover,
it has increased requirements for input data, so that both models and
simulators have a more realistic view of the network. Because of this I
find the document lacks a mapping of the reference architecture and the
typical network management architecture, both abstract, in terms of, for
instance, MAPE loop, as well as an implementation, as Open Source MANO.

Dear all,

We cannot plan a meeting the week before IETF.
We could do another try either as a side meeting during IETF or the week after 
(preferably). I have create a new doodle accordingly:
https://doodle.com/poll/saiwk24iueax4dut?utm_source=poll&utm_medium=link

Depending on the availability of participants, we'll decide.
As a preparation of the discussion during the next NMRG meeting, please have a 
look at the current version of the doc 
(https://docs.google.com/document/d/1I9Z3MiwqdY_CkQI5yWpyKRTvIYjeDqWM5fDIZQ_K63o/edit), 
in particular regarding  challenge #2 data management, and give any 
feedback/comment or add your own inputs to the text.

We'll probably use this challenge to better profile what we expect in terms of 
levels of details.

Best regards
jerome
