Abstract

In an era characterized by pervasive connectivity and the convergence of 5G/6G, IoT, and Edge/Fog computing, network orchestration practises represent a fundamental toolset enabling innovation in communication networks. This tutorial has two main goals. First, it reviews how traditional network management and automation practices have evolved into a more comprehensive orchestration paradigm capable of integrating multi-vendor, multi-technology environments, in a seamless manner. Second, it shows participants that they too can be part of this software (r)evolution in communication networks, demonstrating how easy it can be to "build your own SDN controller" leveraging architectures and technologies which are already of common use. The tutorial addresses key challenges of network orchestration (e.g., interoperability, dynamic resource allocation, and automation) in scenarios where computing is increasingly shifting towards the Edge. To tackle these issues, the tutorial outlines network softwarization and its underlying concepts, and introduce a practical "playground" framework for designing and evaluating microservice-based SDN controllers. Through concrete examples, the tutorial shows how to develop, customize, and test critical functionalities in a sandboxed environment, leading to fully fledged SDN controllers. The ultimate objective is to facilitate participants in understanding the current developments and best practices, and anticipating the upcoming ones, in the broad domain of network softwarization.

A. Tutorial Title

Integrating Quantum Security in 6G Communication Systems: A Conceptual Framework

B. Abstract

The tutorial proposal focuses on the convergence of quantum threats in the domain of 6G networks. It aims to provide an in-depth study of this convergence, starting with background information on quantum attacks, post-quantum cryptography, and quantum key distribution. It will then explore its execution to 6G networks and their quantum-based threats. The tutorial will include a step-by-step demonstration of two of the demos to illustrate the practical implementation of these concepts. The tutorial is designed for participants with no prerequisite knowledge and aims to introduce them to the application of post-quantum cryptography and quantum key distribution to protect the 6G networks. As this topic is gaining significance and relevance in the telecommunications industry, the tutorial offers attendees the opportunity to learn about cutting-edge security issues for 6G networks and their specific applications from the cybersecurity perspective.

AI/ML Integration in 5G and Beyond 5G

Abstract

Machine Learning (ML) and Artificial Intelligence (AI) concepts are gradually being integrated in modern 3GPP standardized cellular networks. The process is initiated by introducing AI/ML functions in the 5G core network (5G CN) and from there, it is expanding towards AI-enabled 5G radio access network (RAN). AI/ML is currently at the early stage of design within 3GPP standardisation and many pathways for its impact are still open. In this talk, we present an overview of AI/ML integration in 5G and Beyond. Following the 3GPP perspective, we start from 5G CN and move towards 5G RAN, focusing on AI/ML impact on 5G and B5G physical layer design. We also cover complementary work done by Open RAN (O-RAN) Alliance. The final part of the tutorial we will demonstrate several use cases of AI/ML integration in 5G/B5G that are active topics in our research team.

Duration and Structure

Tutorial duration: 90 minutes (2 x 45 minutes)
