Computing in Communication Networks

A big step lies ahead, when moving from today’s 5G network to the future 6G. The 5G network introduced a fully softwarized and programmable architecture, with new degrees of freedom still to be fully explored, leading to the next generation of mobile networks (6G). The aim of the tutorial is to illustrate how the emerging paradigms of Software Defined Networking, Network Function Virtualization, and Information Centric Networking will impact on the development of future systems and networks, both from the theoretical/formal as well as from the practical perspective, and more in general how they are leading to the paradigm of “Computing in Communication Networks”. Main focus will be on mobile networks, i.e. 5G and beyond.

The tutorial will provide a comprehensive overview of the individual building blocks (software defined networking; network function virtualization; information centric networks) enabling the concept of computing in future networks, starting from use cases and concepts over technological enablers (Mininet; Docker) and future innovations (machine learning; network coding; compressed sensing) to implementing all of them on personal computers.

Practical hands-on activities will be proposed, with realistic use cases to bridge theory and implementation by several examples, through the usage of a pre-built ad-hoc Virtual Machine (ComNetsEmu) that can be easily be extended for new experiments. The instructions to download the Virtual Machine will be provided in advance of the event.

The main objective of the tutorial will be to expose attendees to the most recent technologies in the field of networking and teach them how to use them in a real setup in the “hands-on” session. A related book written by the two presenters “Computing in Communication Networks” is available, and it provides in-depth description of the concepts and hands-on activities presented in the tutorial, to enable interested attendees to learn additional details on the reviewed technologies.

IMPORTANT: the tutorial will be partly hands-on. Each participant will be able to follow and replicate the examples on his/her personal laptop. Please install the required environment (Comnetsemu) in advance (at least a couple of days before the tutorial), following the instructions available here:
(extensions are not necessary, and not maintained by the tutorial authors)

He was ComSoc Director of Online Content (2016-17). Prof. Granelli was the Dean of Education of the DISI Department for the period 2015-2017, and coordinator of the research and didactical activities on computer networks within the degree in Telecommunications Engineering. He was advisor of more than 80 B.Sc. and M.Sc. theses and 8 Ph.D. theses. He was IEEE ComSoc Distinguished Lecturer for 2012-15 and Visiting Professor at the State University of Campinas (SP, Brazil) and at The University of Tokyo (Japan). He is author or co-author of more than 200 papers published in international journals, books and conferences in networking, with particular reference to performance modeling, cross-layering, wireless networks, cognitive radios and networks, green networking and smart grid communications. Starting from January 2017, Prof. Granelli is Associate Editor-in-Chief of the IEEE Communications Surveys and Tutorials journal (IF=22 - the HIGHEST among all computer science and telecommunications publications!). Prof. Granelli is Area Editor of the IEEE Transactions on Green Communications and Networks. Prof. Granelli is current Chair of the IEEE Communications Society Technical Committee on Transmission, Access and Optical Systems (TAOS TC), and was Chair of the IEEE ComSoc Technical Committee on Communication Systems Integration and Modeling (CSIM TC).

Frank H. P. Fitzek is a Professor and head of the “Deutsche Telekom Chair of Communication Networks” at TU Dresden. He is the spokesman of the DFG Cluster of Excellence CeTI and the 6G-life hub in Germany. He received his diploma (Dipl.-Ing.) degree in electrical engineering from the University of Technology – Rheinisch-Westfälische Technische Hochschule (RWTH) – Aachen, Germany, in 1997 and his Ph.D. (Dr.-Ing.) in Electrical Engineering from the Technical University Berlin, Germany in 2002 and became Adjunct Professor at the University of Ferrara, Italy in the same year. In 2003 he joined Aalborg University as Associate Professor and later became Professor. He co-founded several start-up companies starting with acticom GmbH in Berlin in 1999. He has visited various research institutes including Massachusetts Institute of Technology (MIT), VTT, and Arizona State University. In 2005 he won the YRP award for the work on MIMO MDC and received the Young Elite Researcher Award of Denmark. He was selected to receive the NOKIA Champion Award several times in a row from 2007 to 2011. In 2008 he was awarded the Nokia Achievement Award for his work on cooperative networks. In 2011 he received the SAPERE AUDE research grant from the Danish government and in 2012 he received the Vodafone Innovation prize. In 2015 he was awarded the honorary degree “Doctor Honoris Causa” from Budapest University of Technology and Economics (BUTE). His current research interests are in the areas of 5G/6G communication networks, in-network computing, network coding, compressed sensing, post-Shannon theory, quantum and molecular communication, as well as human-machine interaction in the virtual worlds.
