Tutorial #1: Network Slicing: All-inclusive approach, architectures, orchestration and management with applicability in networks and clouds slicing and challenges for Network 2030
Speaker
Alex Galis, University College London, UK
Tutorial Description
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 softwarization methods such as SDN, NFV, service chains, network virtualization, network programmability 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, 3GPP, other SDOs), Slice Life Cycle Management, Management & Orchestration frameworks, Research & Development projects on Slicing.
The second part presents use cases as an industrial perspective on an overall architecture of network slicing and corresponding operations to demonstrate how some end-to-end slices are deployed, managed and used. It will conclude with the remaining challenges in networking slicing for Network 2030.

Tutorial #2: Packet Processing and Service Assurance constructs for achieving Network Transformation
Speakers
- Sunku Ranganath, Intel, USA
- Matthias Runge, Red Hat, Germany
- Sujata Tibrewala, Intel, USA
- Jayakumar Muthurajan, Intel, USA
Tutorial Description
5G is not just the next generation of networks but is also an innovation platform for services, applications, and connected devices. Moving services and applications to edge is accelerating services “today”, without having to wait for 5G to happen. But what does it take to develop an application that is ready for the Edge and 5G? What sort of hardware, software and ecosystem can enable an application that is future ready.
In this tutorial, we will talk about how packet processing framework like Data Plane Development Kit (DPDK) will help create fast, scalable & agile networks. DPDK has many sample apps which can help speed up the development time for a 5G and edge application. We will talk about one such application IP pipeline. With the foundation of flexible packet processing we will move on to the need of telemetry, which is important to ensure quality and build inter-operable and deployable solutions. Service Assurance (SA) and telemetry are increasingly relevant in 5G networks and Edge deployment as network architectures evolve to become more distributed. 5G and Edge networks introduces dynamic network architectures that require a level of closed loop automation and contextual service assurance for meeting Service Level Agreements (SLAs) establishing itself as a foundational pillar in the network transformation. This tutorial helps introduce the 3 key elements of SA platform of monitoring, provisioning & presentation layers and helps students understand its nuances and complexity.

Tutorial #3: SEBA: SDN Enabled Broadband Access as next-generation access solutions for the Open Networking Foundation ecosystem
Speaker
Abdulhalim Dandoush, ESME-Sudria, France
Tutorial Description
SDN Enabled Broadband Access (SEBA) is an initiative started by AT&T and ONF. It is an exemplar implementation based on the edge computing reference design jointly developed by a number of operators working with ONF based on the CORD project (Central Office Re-architected as a Datacenter).
This tutorial will explain the basic hardware and software elements of CORD with a focus on SEBA as an exemplar implementation. We will start by briefly discussing the key challenges facing the operators and vendors and how to meet them through CORD. Then we address the technologies of CORD (SDN, NFV and Cloud) and describe its architecture. After that we will explain the two basic steps for transforming a traditional Central Office (CO) into a data centre through CORD. A use case of CORD is then discussed through SEBA (the successor of residential CORD, R-CORD). In particular, we will delve deep into the components that make up SEBA including Open Networking Operating System (ONOS) SDN Controller, VOLTHA project, Network Edge Mediator (NEM), Optical Line Terminations (OLTs) , Optical Network Units (ONUs), Passive Optical Network (PON), and Aggregation ( AGG) switches, describing how they all fit together in a modular way. We will show a demo of SEBA with simulated subscribers (using BBSim or PONsim) and provide full instructions for installing SEBA components within a Kubernetes cluster, e.g., three physical compute nodes or virtual Machines. We will explain how to run an end-to-end network slicing with commodity open hardware and open-source software stack. We will provide in depth details of the ONOS Controller and introduce the basic concepts for developing a SDN application.

Tutorial #4: Edge Computing from Cloudlets to ETSI Multi-access Edge Computing and Fog Computing: What is it?
Speaker
Roch H. Glitho, Concordia University, Canada
Tutorial Description
Cloud computing enables cost efficiency through the virtualization of resources residing in data centers. However, these data centers might be too far from end-users and/or devices, and this may be detrimental to applications with stringent delay requirements. Furthermore, regulations may prescribe processing at locations where the cloud provider has no data center. The concept of edge computing has emerged to remedy the situation. It is poised to play a vital role with the deployment of 5G along with applications such as Tactile Internet. Edge computing enables processing closer to end-users and/or devices. Cloudlet, ETSI multi-access edge computing (MEC) and fog computing are the three distinct paradigms that embody it nowadays. The overall objective of this talk is to give the big picture of edge computing. We introduce and contrast the three paradigms, using Tactile Internet, mobile off-loading, content delivery and Internet of Things (IoT) as illustrative application areas. We also sketch the research directions.
