Information Centric Networks: Toward an Internet of Named Objects

By Andrea Araldo, Associate Professor at Telecom SudParis

Biography: Andrea Araldo is Associate Professor at Telecom SudParis (Institut Polytechnique de Paris) and member of the research lab SAMOVAR. His current research interests are Content Distribution in the Internet, Networked Systems Optimization, Intelligent Transportation Systems. He received an MSc degree in Computer Engineering (2012) from Universita di Catania (Italy) and a PhD degree in Computer Networks from Telecom Paristech and Universite Paris Sud (France -2016). He was visiting researcher at KTH Royal Institute of Technology (Sweden -2016) and Postdoctoral.

Abstract: The rationale behind Information Centric Network (ICN) is that more than 80% of traffic consists of immutable “objects”, e.g. multimedia content like video, each of them transmitted many times to different users. Users just request to retrieve the desired object, no matter the host in which it is stored. Therefore, differently from current IP networks that connect users to hosts, in ICNs users request content by name, without specifying a destination host address. The ICN is then responsible to retrieve it from the “best location”. “In-network caching” allows to replicate popular content in several locations, directly on routers. Content can be thus served from sources close to the users, thus decreasing redundant transmissions and reducing traffic. This tutorial introduces the main innovations of ICN: in-network caching, naming schemes, routing by names, content-based security, content-routers. He presents the main theoretical results to model and evaluate the performance of ICN, the different philosophies behind the most relevant ICN architectures, some notable experimental applications, the open source software for simulating or implementing ICN, some developed ICN hardware devices. The tutorial also discusses possible reasons of the slow adoption of ICN in the current Internet, as well as the fundamental concepts of ICN being adopted in IoT, vehicular networks and Content Delivery Networks (CDNs). Research and industrial perspectives and challenges conclude the tutorial.

Shannon versus Turing, the limit of Artificial Intelligence

By Philippe Jacquet, Research Director at Inria

Biography: Mathematical oriented background, Philippe Jacquet is expert in the analysis of algorithm, in particular in the algorithms related to networking, Information Theory, data analytics. And Artificial Intelligence.

He has been a major contributor to the specification of mobile ad hoc routing protocols, in particular the Optimized Link State Routing that has been standardized in the IETF.

After eight years as head of a math department in Nokia Bell Labs, Philippe Jacquet is back to Inria.

Abstract: We will describe an imaginary dialogue between Shannon and Turing about Artificial Intelligence (AI). The enormous impact of AI and its most recent advances with Deep Learning should not hide that this technology must conform to the laws of Information Theory, i.e. that in order to become autonomous and efficient in solving problems an AI system should absorb a huge quantity of entropy from the external world. Furthermore, we will show that even with an infinite computing power, some problems (and some are surprisingly simple) are not fully learnable.

5G: Key technologies, standard and evolutions

By Marceau Coupechoux, Professor at Telecom ParisTech and École Polytechnique.

Biography: Marceau Coupechoux is Professor at Telecom Paris and École Polytechnique. He graduated from Telecom Paris and University of Stuttgart, and obtained his PhD from Institut Eurecom. He is member of the ARCEP expert group on mobile networks (french telecom regulator). His research interests are the performance evaluation, the optimization and the resource management of wireless and cellular networks.

Abstract: The Release 15 of 3GPP has been recently frozen. This is the first 5G New Radio standard, also called 5G Phase 1. As first 5G deployments are starting around the world, especially in US and in Korea, there are many expectations around this new generation. Compared to previous ones, it is expected to address the requirements of several vertical markets like Industry 4.0, vehicular networks or massive IoT. This tutorial will give an overview of the potential use cases, of the key emblematic technologies of 5G, and some research perspectives for the evolutions of cellular networks.
