Tutorial #1: Network Softwarization in 5G: recent trends
Speaker
Adlen Ksentini, EURECOM, France

Tutorial Description

5G is assumed to not only increase the physical data rate, but also support a diverse set of new services coming from the vertical industries (e.g., automotive, eHealth and IOT). These services are known to have different needs in terms of network performance, such as low latency access, high communication reliability and the support of massive numbers of devices. According to their type, 5G classifies services into: enhanced Mobile BroadBand (eMBB), ultra Reliable Low Latency (uRLLC) and massive Machine Type Communication (mMTC). Therefore, the “one size fits all architecture” currently in use by 4G is no more sufficient, leading to rethink the network architecture at all system levels. In this context, network slicing is envisioned as the key solution to create virtual network instances tailored to vertical services, on top of a shared network infrastructure. Network Slicing relies on the advances made in network softwarization, i.e. Network Functions Virtualization (NFV), Software Defined Networking (SDN) and cloud computing, to provide flexible and dynamic virtual networks.

This tutorial aims to give insight to network softwarization and its usage in 5G, focusing on Network Slicing and presenting the recent advances in terms of architecture and technology enablers. The tutorial starts by introducing concepts related to network softwarization, such as SDN, NFV and Mobile Edge Computing (MEC). Afterwards, the tutorial introduces the newly 5G architecture, based on Network Slicing, as defined by 3GPP and ETSI, covering: (i) Radio Access Network (RAN); (ii) Core Network (CN) and (iii) Life Cycle Management (LCM) of network slices. An implementation of an end-to-end network slice using OpenAirInetrface(OAI) will be used as example to show the enabling technologies. The tutorial will then discuss the relation between MEC and 5G, particularly on solutions to ensure MEC slicing. Finally, conclusions and research perspectives will be discussed towards 5G long-term evolution.

Tutorial #2: Packet Processing and Service Assurance constructs for achieving Network Transformation

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.
