3rd Workshop on Advances in Slicing for Softwarized Infrastructures (S4SI 2020)
Panel: Network Slicing is multifaceted but does its approach and understanding need to be fragmented?
Abstract: Network Slicing keeps growing in significance in the academic and industrial communities. Network Slicing can be defined from different functional or behavioral perspectives, as well as from different viewpoints depending on the stakeholder (e.g., verticals, solution providers, infrastructure owners) and the technical domain (e.g. cloud data centers, radio access, packet/optical transport networks). Standardization bodies and open source projects are being involved in some forms of network slicing support. How far are these views from each other? Is fragmentation leading to incompatible approaches or is there some hope of convergence, at least at conceptual levels? What is the next frontier in Network Slicing? These and other questions will be thrown to our panel experts after introducing their lightning viewpoints.

Projeto financiado pela FAPESP Processo: 18/23101-0
Resumo
Em relatório publicado pelo Comitê Gestor da Internet no Brasil (CGI.br) em 2018, em termos de acesso à Internet por banda larga no Brasil, há uma ampla desigualdade entre as classes econômicas A/B (maior) e D/E (menor), fato evidenciado nas análises entre as áreas urbanas e rural. Além de evidenciar que cerca de 34% dos brasileiros ainda não possuem acesso à Internet, o relatório também explica que o acesso à Internet é um catalisador de desenvolvimento social, econômico e tecnológico: fato consagrado em diversas pesquisas internacionais e enfatizado pela organização Internet Society. Redes sem fio comunitárias têm se tornado um meio sustentável de promover meios acessíveis de conexão à Internet,tanto em áreas rurais remotas quanto em regiões urbanas densas. Em sua ampla maioria, redes sem fio comunitárias adotam a tecnologia wifi, no entanto apenas recentemente, devido ao desenvolvimento de tecnologias de código livre e de baixo custo, o padrão Long-Term Evolution (LTE) começou a ser explorado para estes fins. Logo, não há conhecimento na literatura acadêmica de estudos que busquem utilizar e melhorar o padrão LTE aplicado à redes sem fio comunitárias. Nesse escopo, esta proposta busca trazer conceitos inovadores de novos paradigmas de redes, Redes Definidas por Software (Software Defined Networks -SDN) e Virtualização de Funções de Rede (Network Functions Virtualization - NFV), para o desenvolvimento de redes LTE comunitárias. Por meio de uma metodologia ágil de testes,conceitos de SDN e NFV serão aplicados no desenvolvimento de mecanismos que realizem o gerenciamento inteligente de recursos de redes LTE comunitárias visando desempenho eficiente e tolerância a falhas robusta, i.e., a sustentabilidade da rede. Todos estes estudos serão feitos tendo por base um levantamento de características de redes sem fio comunitárias em operação no Brasil proposto para o início do projeto. Ao final, a execução desta proposta irá produzir um material didático elucidando as formas de modelamento, implantação, e manutenção sustentável de uma rede LTE comunitária nos moldes dos estudos realizados por esta proposta (i.e., com todos os dados, avaliações, metodologias, e protótipos). Este material será utilizado como base de uma proposta de implantação de uma rede LTE comunitária no Brasil junto ao programa "Beyond the Net" da Internet Society.

Standard Protocols for Heterogeneous P2P Vehicular Networksijtsrd
Vehicular Communication Systems are developing form of networks in which moving vehicles and side road units are the main communicating nodes. In such networks, vehicular nodes provide information to other nodes via Vehicle to Vehicle communication protocols. A vehicular communication system can be used to support smart road applications such as accidents and traffic congestion avoidance, collision warning forwarding, forensic accidents assistance, crime site investigation, and alert notification. However, current Vehicular Communication Systems suffer from many issues and challenges, one of which is their poor interoperability as they lack standardization due to the inconsistent technologies and protocols they use. This paper proposes several standard protocols and languages for P2P vehicular networks that are built using heterogeneous technologies and platforms. These standards consist of three protocols a Standard Communication Protocol which enables the interoperable operation between the heterogeneous nodes of a P2P Vehicular network an Autonomous Peers Integration Protocol which enables the self integration and self disintegration of functionalities and a Standard Information Retrieval Protocol which allows the P2P network to be queried using a standard high level language. In the experiments, a case study was presented as a proof of concept which demonstrated the feasibility of the proposed protocols and that they can be used as a standard platform for data exchange in P2P Vehicular Communication Systems. As future work, Service oriented architectures for vehicular networks are to be investigated while addressing security issues such as confidentiality, integrity, and availability.

TRUST BASED ROUTING METRIC FOR RPL ROUTING PROTOCOL IN THE INTERNET OF THINGSpijans
While smart factories are becoming widely recognized as a fundamental concept of Industry 4.0, their implementation has posed several challenges insofar that they generate and process vast amounts of security critical and privacy sensitive data, in addition to the fact that they deploy IoT heterogeneous and constrained devices communicating with each other and being accessed ubiquitously through lossy networks. In this scenario, the routing of data is a specific area of concern especially with the inherent constraints and limiting properties of such devices like processing resources, memory capacity and battery life. To suit these constraints and to provide the required connectivity, the IETF has developed several standards, among them the RPL routing protocol for Low powerand Lossy Networks (LLNs). However, and even though RPL provides support for integrity and confidentiality of messages, its security may be compromised by several threats and attacks. We propose in this work TRM-RPL, a Trust based Routing Metric for the RPL protocol in an IIoT based environments. TRM-RPL uses a trust management mechanism to detect malicious behaviors and resist routing attacks while providing QoS guarantees. In addition, our model addresses both node and link trust and follows a multidimensional approach to enable
an accurate trust assessment for IoT entities. TRM-RPL is implemented, successfully tested and compared with the standard RPL protocol where its effectiveniness and resilience to attacks has been proved to be better.

IT teams face unprecedented challenges to support dynamic application requirements on top of a rigid legacy infrastructure. A vendor-agnostic orchestration helps deliver rapid network
services for multi-vendor infrastructure. Anuta NCX platform with it’s layered, YANG model-driven and abstraction approach helps in delivering vendor neutral, extensible and maintainable
services for multiple domains such as Branch/CPE, Data Center, Cloud, and Carrier Core networks. The NCX platform enables customers and partners to develop their own Service and Device models for complete customization within few days. Many large enterprises and service providers have deployed NCX to orchestrate their brownfield and greenfield networks.
CONTAINERIZED SERVICES ORCHESTRATION FOR EDGE COMPUTING IN SOFTWARE-DEFINED W...IJCNCJournal
As SD-WAN disrupts legacy WAN technologies and becomes the preferred WAN technology adopted by corporations, and Kubernetes becomes the de-facto container orchestration tool, the opportunities for deploying edge-computing containerized applications running over SD-WAN are vast. Service orchestration in SD-WAN has not been provided with enough attention, resulting in the lack of research focused on service discovery in these scenarios. In this article, an in-house service discovery solution that works alongside Kubernetes’ master node for allowing improved traffic handling and better user experience when running micro-services is developed. The service discovery solution was conceived following a design science research approach. Our research includes the implementation of a proof-ofconcept SD-WAN topology alongside a Kubernetes cluster that allows us to deploy custom services and delimit the necessary characteristics of our in-house solution. Also, the implementation's performance is tested based on the required times for updating the discovery solution according to service updates. Finally, some conclusions and modifications are pointed out based on the results, while also discussing possible enhancements.
SDN Performance evaluation for floodlight controller and OVS controller using adaptive approaches (i.e. statistical approach and genetic algorithm approach).
According to a new Gartner report1, “Around 10% of enterprise-generated data is created and processed outside a traditional centralized data center or cloud. By 2022, Gartner predicts this
figure will reach 75%”. In addition to hosting new 5G era services, the other major network operator driver for edge compute and edge clouds is deploying virtualized network infrastructure, replacing many dedicated hardware-based elements with virtual network functions (VNFs) running on general purpose edge compute. Even portions of access networks are being virtualized, and many of these functions need to be deployed close to end users. The combination of these infrastructure and applications drivers is a major reason that so much of 5G era network transformation resolves around edge cloud distribution.
In these slides, you will be able to learn about what we will need to do in order to enable 5G and how open source can help accelerate that transformation.

Fluid Network Planes – An overview of Network Refactoring and Offloading Trends. Keynote at IEEE Netsoft'19, Paris, 2019.
Keynote Description
10 years have passed since the term SDN was coined in 2009. Since then, the three letter acronym has kept evolving through broadening definitions until our state of affairs where SDN means little unless adequately technically elaborated.
Among the key aspects of SDN is the refactoring of the network control plane. At the crossroads, NFV introduces new ways to refactor network functions, be them control or data plane related.
Despite the softwarization flag of SDN and NFV, the hardware/software continuum is as relevant as ever, offering new offloading opportunities at node and network-wide scales.
In this talk, we will review evolving transformations behind network softwarization with a special focus on network refactoring and offloading trends leading to “fluid network planes”, where the location and HW/SW embodiments of network functions becomes blurry, from the edge to core, from one administrative provider to another, from programmable silicon to portable lightweight virtualized containers.
The realization of network softwarization, an overarching buzzword to encompass all software-centric developments from the Software-Defined Networking (SDN) and Network Function Virtualization (NFV) trends, is being enabled through a set of innovations in high-speed data plane design and implementation. Recent efforts include te-architecting the hardware-software interfaces and exposing programmatic interfaces (e.g., OpenFlow), programmable hardware-based pipelines (e.g. Protocol Independent Switch Architecture – PISA) along suitabe programming languages (e.g., P4), and multiple advances on low overhead virtualization and fast packet processing libraries (e.g. DPDK, FD.io) for Linux based general purpose processor platforms. This talk provides an overview of relevant ongoing work and discusses the trade-offs of each design and implementation choice of software-defined dataplanes regarding Programmability, Performance, and Portability.
This talk provides a 2017 updated view on SDN and the broader Network Softwarization trend (e.g., + NFV, P4) aiming and trying to provide a clarifying view on the evolving SDN definitions (beyond a purist view) by explaining the main characteristics of SDN embodiments in 2017+

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

5. Panel theme
Network Slicing is multifaceted
but does its approach and understanding need to be fragmented?
● Network Slicing keeps growing in significance in academia and industry
● Network Slicing can be defined from different functional or behavioral perspectives, as
well as from different viewpoints depending on the stakeholder (e.g., verticals, solution
providers, infrastructure owners) and the technical domain (e.g. cloud data centers, radio
access, packet/optical transport networks).
● Standardization bodies and open source projects are being involved in some forms of
network slicing support.
● How far are these views from each other?
● Is fragmentation leading to incompatible approaches or is there some hope of
convergence, at least at conceptual levels?
● What is the next frontier in Network Slicing?

● The NGMN White Paper about Network Slicing widely accepted (3GPP, ETSI
MANO, ...)
● In 5G all necessary mechanisms for slicing have been defined (selection, LCM,
run-time management, management delegation,...)
● GSMA has defined GST (Generic Slice Template) and NEST (Network Slice Type)
per use case
● Network Slice is a software entity - do we need to standardize everything?
● Still no large scale deployment of the technology
○ Vendors/verticals/operators are not ready yet?
○ Do we need to improve the existing approaches (RAN,...)?
○ Are there serious implementation issues? Do we have COTS solutions?
○ No market yet for network slicing?
○ Do we have killer application?

36. Wireless Network Slicing:
Considerations
• Need to advance to spectrum-level towards full e2e slicing
capabilities
• SDR as enabling technology to enforce isolated service delivery at
the spectrum level
• AI-empowered wireless:
• ML can learn to predict settings best-fitted to the elasticity
• Predict demand and optimize channel settings
• Predict the load of each BS on the fly, figure out the location of devices
and decide about best BS to handover
40. Network Slicing is multifaceted but does its approach and understanding need to be
fragmented?
It doesn’t need to be, but it is, as it depends on where you start, and what is meant by
slicing ? It depends on your answer of what you think a slice is, but I believe it should be
something new.
A slice should be an addressable and manageable end-to-end abstraction, composed
from slice parts created over the underlying resources, but that means all the parts:
network, data center, storage, mobile edge, RAN, ...
41. Network Slicing is multifaceted but does its approach and understanding need to be
fragmented?
For slicing to be globally useful, in general, there needs to be agreement on:
● the right abstractions,
● the right building blocks,
● the right separation of concerns,
● the right composability,
● the right mechanisms to be in place for slice lifecycle management: to create, adjust,
and remove slices
42. How far are these views from each other?
Due to the different layering of the systems, and the different starting points we are
seeing some divergence.
It depends on how you construct a slice, which layer does the slicing, and what the
conceptual abstraction looks like.
Until you have decided these, you don't know what or how you can manage and
orchestrate them.
43. How far are these views from each other?
Some approaches suggested for slicing are not from first principles.
There are slicing processes which seem to rely on some magic. The mechanism to make
it work is left to someone else.
Other approaches make some big assumptions or rely on existing components which will
need the necessary extensions.
44. Is fragmentation leading to incompatible approaches or is there some hope of
convergence, at least at conceptual levels?
It is generally agreed that slicing gives an extra mechanism overlayed on the underlying
resources for the deployment of services with particular requirements.
We see standards being created by different bodies, with no testing or evaluation.
Renaming or relabelling an existing features and/or functions is not a slice:
A VPN is still a VPN ! You haven't created something new.
45. Is fragmentation leading to incompatible approaches or is there some hope of
convergence, at least at conceptual levels?
There is a naming anomaly where calling a slice "a network slice", but having VMs running
NFVs which are in a Data Center causes a bit confusing. If it uses DCs, then it's not just
the network part.
Having a non-symmetric model where you can partition a network, and partition the
storage, but not partition the Data Center gives poor composability, poor manageability
capabilities and characteristics.
Until the standards address these aspects, I think fragmentation will continue.
46. What is the next frontier in Network Slicing?
Concentrate on the aspects needed to complete:
● dynamic allocation of all slice parts
● end-to-end composability of the slice parts
● management interfaces for all slice parts
● create the lifecycle operations for slices
● building the right abstractions and layers for slicing
● design and build all new components and sub-systems need to make slicing work
● design APIs for addressing slices
47. What is the next frontier in Network Slicing?
Convergence of the concepts and the operations, and of course the standards.
The ability for operators to allocate network segments/parts, which meet slice
requirements, in a dynamic on-the-fly manner by returning all the end-point information,
in software, at run-time, and not in a written contract.
