Tutorial #1

Title: Recent Advances in Data Engineering for Networking


To address the complex issues that larger and highly integrated networks face in the design, analysis, deployment and management phases, recent advances in data science and engineering technologies in both academia and industry have spurred the adoption of various Artificial Intelligence (AI)/Machine Learning (ML) platforms and frameworks in telecommunication network infrastructures. In this tutorial, we aim to provide a comprehensive and thorough overview of the recent advances in data engineering frameworks and link the capabilities of the data engineering ecosystem with a possible connection to future telecommunication systems in the context of network management and orchestration.

Some special features of this tutorial are:

  • A clear link between the data engineering ecosystem (including data connection, data ingestion, data processing & analysis, data storage, data monitoring & visualization and data management & orchestration frameworks),
  • Recent developments in networking, an overview of standardization efforts in network management and orchestration and how these can be related to data engineering frameworks,
  • The relationship to data science frameworks, ML platforms used in the industry, and related data engineering use cases for telecommunications networks will be discussed.
  • Two examples on log management in NFV service orchestration and AI/ML-driven scaling of digital service will also be demonstrated.
  • Finally, gap analysis, challenges, and future directions will be discussed.

The target audience is networking practitioners who are willing to get involved in the data engineering ecosystem. The attendees to this tutorial will have the chance to learn more about data engineering for networking and its applications from the perspective of telecommunication operators. The audience is expected to have basic knowledge of networking as a prerequisite.

Tutorial #2

Title: Building Network Digital Twins for Next-Generation WLANs using Graph Neural Networks


Network operators face a significant problem when it comes to dynamically accommodating and reacting to customer expectations due to, among other reasons, the exponential growth in network scale and an extreme set of requirements in network services, such as ultra-low latency, highly reliable communication, and improved user experience. In fact, as managed networks become more complex, network operation and maintenance become more difficult and costly to carry out.

By building Network Digital Twins (NDTs), network operators can create network optimization strategies, carry out what-if analyses, troubleshoot problems, and plan network upgrades. The operations can be executed in real-time without endangering the physical network because interacting with the NDT does not require access to the real network, only its data.

In this tutorial we envision Next-Generation Wireless Local Area Networks (WLANs), where a highly degree of automation is enabled by techniques such as SDN, NFV and ML. In such context, we will build an NDT using the latest advances in ML to predict WLANs performance when different configurations of channel bonding are enforced.

The tutorial will address the following topics:

  • Part I – Introduction to wireless networking management
    • Background in Wi-Fi and its medium access mechanisms.
    • Background in Channel Bonding
    • Challenges in Channel Bonding        
    • Necessity for digital twins.
  • Part II – Hands-on: Building an NDT for Next-Generation WLANs with traditional AI/ML/DL
    • Introduction to dataset
    • Introduction to AI/ML/DL techniques
    • Hands on: Building an NDT with traditional AI/ML/DL
  • Break
  • Part III – Hands-on: Building an NDT for Next-Generation WLANs using Graph Neural Networks
    • Motivation for using Graph Neural Networks (GNNs) in topology-based problems
    • Introduction to GNNs
    • Hands-on: Building an NDT for Next-Generation WLANs using GNNs.
  • Part IV – State of the art and beyond
    • Recent advances in building NDTs

This tutorial is mainly intended for researchers interested in the intersection between novel AI/ML techniques and wireless network management, optimization, and planning. A brief introduction to Machine Learning and Wireless Networks will be given in this tutorial, but some background in the topic would be advantageous.
