Tutorial 1

Title: Network Slicing: A holistic architectural approach, orchestration and management with applicability in mobile / fixed networks and clouds
Speaker: Prof. Alex Galis
Date: November 5^th, 2018, 9:00 - 12:30 AM

Abstract: This half-day tutorial will present the concepts, design and technologies enabling Network Slicing (NS). NS is both an old and new idea. While its scope and definition continue to evolve, there is reasonable level common understanding of the key central role it will play in future network and service delivery scenarios. The significant value of network slicing architecture will be seen in terms of dynamic and non-disruptive control, operation and scaling of services in a network slice by the tenant of the slice. In order to achieve this, a fundamental change in how we administer networks is required in terms of abstraction, separation and mapping of forwarding, control and management aspects of a service. There exists a possibility of applying already mature methodologies such as SDN, NFV, service chains, network virtualization, etc. The challenge lies enabling an operator to flexibly use such tools in a light-weight manner with in a viable architectural framework. The first part of this tutorial presents the main slicing concepts and their history, key slicing characteristics and usage scenarios, Standard Organization activities in network slicing (ITU-T, IETF, ETSI, other SDOs), Slice Life Cycle Management, Management & Orchestration frameworks, Research & Development projects on Slicing. This part will conclude with identifying research and development challenges in Network Slicing. The second part presents industry use cases as a perspective on an overall architecture of network slicing and corresponding operations to demonstrate how an end-to-end slice couple be deployed and managed. It shows many existing standard techniques can be used to simplify network slice workflows. This part will wrap up with a report on progress and approach currently used for standardization of requirements of network slices.

Tutorial 2

Title: Network Function Virtualization (NFV) Enabling Technology for 5G
Speaker: Faqir Zarrar Yousaf
Date: November 5^th, 2018, 13:30 - 17:00 PM

Abstract: Communication networks’ architecture and technologies are undergoing through their next evolutionary phase towards 5G. This evolutional phase is markedly different from the previous phases in that the complete concept of networking is undergoing a paradigm shift. Networks are now moving beyond as mere bit-pipes towards a highly agile and programmable entity that can be tailored to the varying demands of the various industry verticals while ensuring conformance to stringent performance requirements and expectations of 5G.  New technologies and architectures are being developed that will provide the customers their own isolated network “slices” over the same infrastructure thus creating new use cases and business models. NFV is now recognized as one of the key enabling technologies for the management of 5G networks, and the NFV Management and Orchestration (MANO) framework and its various aspects is being specified keeping in view of management and orchestration of virtualized network functions and services. The goal of this tutorial is:

1. To highlight the challenges and requirements for the management of 5G networks;

2. To impart in-depth knowledge about the ETSI NFV MANO system framework;

3. To explore the features/capabilities/functions/services of NFV MANO system in view of the 5G networks requirements/challenges.

This tutorial will also discuss the various integration options of the NFV MANO with the SDN networks and how the two technologies complement each other in imparting a truly programmable and agile network platform. At the end of the proposed 180 minute tutorial, the audience is expected to have an effective knowledge of NFV MANO system and its key role in the context of 5G.

Tutorial 3

Title: Blockchain and Smart Contracts – From Theory to Practice
Speaker: Bruno Rodrigues, Roman Blum, Thomas Bocek, Burkhard Stiller
Date: November 9^th, 2018, 9:00 - 17:00

Abstract: Blockchains and Smart Contracts are more recent technologies and they help building the foundation of a truly distributed digital society. This tutorial provides at first a basic theoretical introduction into blockchains and Smart Contracts and secondly a practical interaction with a blockchain and initial aspects for the development of Smart Contracts. Hence, the audience is guided through the deployment of an Ethereum Blockchain and the creation of an ERC20 token (Ethereum Request for Comment Number 20) using Smart Contracts. In this regard, besides the practical support of the instructors, the audience will receive a key basis and an introduction to major concepts and issues with respect to blockchains and Smart Contracts. At the end of the tutorial, the audience is expected to be not only able to create blockchains and Smart Contracts, but also to interact on a detailed technical level with these components.
