2019 ComSoc Autumn School

This presentation highlights the role of 5G in the factory of the future. It consists of two parts: the first part targets a lay audience and provides general information on industrial Internet of Things, with focus on the associated values and business requirements. The technology enablers for such unification between the worlds of telecommunications and industrial automation are put forward, highlighting the role of network slicing. The second part touches more technical aspects of industrial 5G deployments, and discusses solutions offering increased levels of reliability at the radio access domain, as well as network function availability. Emphasis is put on the data duplication approach, showing an analysis on the achievable reduction on packet drops in various load scenarios. The presentation closes with an overview of positioning (localization) approaches, underlining the advances of 5G positioning to predecessor technologies and their potential to meet the stringent industrial requirements.

This tutorial is intended to teach the basics of Software Defined Networking and Network Function Virtualization by providing both theoretical concepts as well as
hands-on experience. By merging theory with practice, the audience will be able to understand the concepts and possibilities of these two emerging communication
paradigms. In the first part of the tutorial, Software Defined Networking will be introduced as a novel paradigm for controlling network infrastructures and then
implemented by using the OpenFlow protocol and related controllers. By using a proper Virtual Machine running mininet emulation software, the audience will be
able to implement a simple SDN network based on OpenFlow and analyze its behaviour. In the second part of the tutorial, NFV and the MANO architecture will be
introduced, and the audience will have the chance to experiment with such technology by using docker to deploy available services and also design new ones.

This tutorial gives an overview of problems, models and algorithmic techniques.
arising in the context network slicing, with a focus on resource allocation and optimization,
but also including an excursion to security aspects.
In particular, we will cover network virtualization and virtual network embedding problems,
routing via waypoints and traffic engineering, and algorithms for local fast failover.

Service providers are in a continuous evolution in order to satisfy the changing and variable service demand of the end users. This affects not only to the service offering but also to the network supporting the delivery of such services. A key part of it is the transport infrastructure. Network operations are heavily influenced by the control and management capabilities available. The paradigm of Software Defined Networking (SDN) becomes the central point of network evolution, covering the majority of existing gaps. Key aspects of operations such as network provisioning or troubleshooting can then benefit from advanced tools and mechanisms. Software Defined Networking (SDN) originally entailed the decoupling of control and forwarding planes in the network elements, with the deployment of a centralized controller with the complete network view, running intelligent algorithms and applications (either as part of the controller or on top of it) and instructing the nodes accordingly. This original view, when ported to real carrier networks, has been evolved slightly towards an architecture where the centralized control assists the network elements on the forwarding tasks, providing single and unified control environment for network operations and at the same time optimizing the usage of network assets. The network elements yet retain control capabilities (in some cases alleviating some signaling tasks) but leveraging on the centralized controller for end-to-end and cross-layer actions through programmable interfaces. This session presents a realistic SDN approach towards and standards-based architecture for softwarized network operation.
