Tutorial A: Towards programmable Mobile Networks
FRIDAY, May 12, 09:00 - 12:30
Speaker: Adlen Ksentini, EURECOM, France
Several ongoing research and deployment scenarios envision the use of SDN to manage mobile network. Each scenario brings new ideas and challenges to accommodate SDN concepts to mobile network. This tutorial will present recent advance on the use of SDN in 4G and beyond (5G). It will shed light on the advantage of using SDN in mobile network, and the related challenges and issues. The tutorial begins by reviewing the different mobile systems defined by 3GPP, including the Evolved Packet Core (EPC) and Radio Access Networks (RAN). After a short discussion on the basic principles of LTE, the tutorial presents the major architectural enhancements that have been already standardized within 3GPP for supporting Evolved Packet System (EPS). The tutorial will be afterwards touching the ongoing advances in SDN. A particular focus will be done on the current technologies around SDN controllers and the different available APIs (Southbound and Northbound). The tutorial will then review and discuss several use-cases and architectures to introduce SDN in mobile network to manage EPC and RAN, presenting the advantage and inconvenient of each solution in terms of performance and implementation. The tutorial will also present the ongoing solutions to combine SDN and Network Function Virtualization (NFV) to enable the programmability of the mobile network architecture, and ease the deployment of Mobile Edge Concept (MEC) principle. The tutorial will discuss the implementation results of SDN on Open Air Interface (OAI) (Open Source of 4G EPC and eNodeB). Finally, the conclusion will show how to enable Network Slicing, highly recommended in 5G, using the mechanisms described throughout the tutorial.

Tutorial B: Programming data-planes in P4, a high-level language for packet processors
FRIDAY, May 12, 09:00 - 12:30
Speakers: Salvatore Signorello & Jérôme Francois, University of Luxembourg & Loria - University of Nancy, France
Recent advances in literature and latest available chip-designs showcase fully programmable forwarding elements performing at terabit rate. Once this next-generation of network devices will be commonplace, there will be the need to program them, as well as the old fixed-function ASICs, to implement desired behaviors. P4 was originally proposed as a protocol-agnostic, target-independent language for fully programmable network devices. One common open high-level language, instead of a plethora of proprietary microcode-like languages, could ease prototyping, testing and disseminating new ideas. Ideally, P4 programs will be written once and then ported many times regardless of the hardware setting, though assuming that there will be compilers for different platforms. Since its inception, the P4 language has generated a notable momentum across both the industry and academia, gathering together the biggest network operators and some visionary academics in the P4 Language non-profit consortium (http://www.p4.org/). Moreover, the potential of the language to validate novel network protocols has already been showcased by several research works. Today, an hectic ecosystem of open source software tools is maintained and developed by the P4 community. In addition to that, some important network vendors, like Netronome, have started providing support to compile and execute P4 programs on their hardware. This tutorial will introduce the participants to the P4 language, providing them with the knowledge necessary to develop and prototype their own ideas in P4. More in detail, the tutorial will first introduce the motivation that led to the language creation, the consortium objectives and its ongoing activities. Then, the tutorial overviews the language programming model and main syntax. Finally, the development environment is introduced and some assignments to be implemented in P4 and run on different targets are proposed to the audience.

Tutorial C: The Information-Centric Networking Challenge from a Network and Resource Management Perspective
FRIDAY, May 12, 14:00 - 17:30
Speaker: Ioannis Psaras, University College London, UK
Information-Centric Networking (ICN) has been the topic of endless discussions in the research community in the past few years, for two main reasons: i) due to the huge advantages that such a networking paradigm would bring, and ii) due to the difficulty of implementing such a radical change on top of the current Internet. Information-Centric Networks work on the basis of content, rather than end-hosts. In the vast majority of Internet transfers, users are not actually interested in the host-to-host communication per se, but instead in the actual content/data/information that the host in question holds. Therefore, instead of searching for the host that holds the content of interest, ICN focuses on the search and resolution of the content itself, irrespectively of where the content is, who is the host of the content, or how can the content-host be reached. The evolution steps from the client-server model to the ICN proposal included IP Multicast, Web-caching, Content Distribution Networks (CDNs), Peer-to-Peer computing, but were also influenced from the wireless and mobile world, i.e., Mobile Ad Hoc Networks (MANETs), opportunistic networks and Delay-/Disruption-Tolerant Networks (DTNs). In this tutorial, we will start off with a short summary on the evolution of content-based networking through the years, which is necessary in order to understand the foundations of the ICN pyramid; then we will dive into the details of specific research challenges in ICN. These challenges span from network layer naming and addressing to in-network caching and resource management and further to application layer issues. Of particular importance in the ICN area is the issue of network management, which has been a topic of extensive research in the Internet community. An ICN approach to networking has the potential to significantly ease network management operations. We will therefore, pay particular attention to the issue of network and resource management from an ICN perspective with special focus on edge-cloud and fog computing environments. The open issues in the ICN area far outweigh the solved ones and hence, our discussion and presentation will focus on the related tradeoffs and research directions for future ICN investigations.
Dr Ioannis Psaras is Senior Researcher and an EPSRC Fellow with the Department of Electronic and Electrical Engineering of University College London. He has participated in several EU FP7, H2020 and EPSRC projects focusing on future Internet architectures with a special focus on resource allocation and management. His broad research interests include Congestion and Flow Control, Transport-layer Protocols, Delay-/Disruption-Tolerant Networks (DTNs), User-Provided and User-Centric Networks and Information-Centric Networks. His work in Information-Centric Networking has made substantial impact in the research community and is considered to be part of the leading forces towards this new networking paradigm. He is active in the ICNRG group of the IRTF on ICN and has co-authored one of the first Internet Drafts on “Research Challenges of ICN”, which has recently become RFC 7927. He has received four Best Paper Awards at IFIP Networking 2012 and 2015, IEEE LANMAN 2016 and ACM MobiArch 2016, all in the area of Information-Centric Networks. He has recently received more than £1M from the UK Engineering and Physical Sciences Research Council (EPSRC) to pursue a 5-year Early Career Fellowship on the interplay between Information-Centric Networks, Software-Defined Networks and edge-/fog-computing.

Tutorial D: Powering Internet of Things with Cloud and NFV for Cost Efficient and Agile Applications and Services Provisioning
FRIDAY, May 12, 14:00 - 17:30
Speaker: Roch Glitho, Concordia University, Canada
The Internet of Things (IoT) exploits the ubiquity of objects such as sensors and actuators which could be networked and collaborate for meeting specific goals. The expected applications and services are numerous and cover all aspects of business and everyday life. However provisioning these applications and services in a cost efficient and agile manner remains an uphill task. The deployment of wireless sensor networks (a key building block of IoT) for instance, remains applications/services specific, precluding cost efficiency through re-use by new applications and services. The deployment of middle boxes services such as IoT gateways also remains quite cumbersome. Cloud computing and NFV, emerging paradigms for cost efficient and agile applications and services provisioning, are poised to change the current state of affairs. This tutorial reviews in three parts the state of the art and discusses the research directions. The first part introduces the basics of applications and services provisioning, IoT, cloud computing and NFV. The second part is devoted to cloud based IoT applications and services provisioning. The approaches proposed so far for IoT virtualization to enable cost efficiency are reviewed. The works on IoT platforms as a Service (PaaS) for rapid and easy applications and services provisioning are also discussed. A concrete cloud based - IoT fire detection and fighting application we have prototyped in our lab is presented as a case study. In the last part NFV based IoT applications and service provisioning is reviewed with a focus on virtual network function (VNF) chaining and deployment issues. A concrete NFV based IoT gateway we have designed and prototyped in our lab is presented as a case study. We conclude by discussing research directions including how fog computing could complement cloud and NFV for unleashing even more powerful IoT applications and services.
