09:00 – 09:30Introduction, Welcome by the chairs, Best Paper Award Ceremony – Anna Sperotto and Roland van Rijswijk-Deij

09:30 – 10:30   Keynote: Impactful Measurement Research Costs Time and Nerves – Lessons from Internet Security (Matthias Wählisch, Freie Universität Berlin)
session chair: Anna Sperotto


The Internet is the largest distributed, networked system that is currently deployed. Measuring the Internet and the services on top is pivotal to improve security and reveal current trends towards consolidation and centralization. Unfortunately, the Internet was never meant to be measured. In this presentation, I will discuss our work that aims for a better understanding of security deployments in the Internet core and edge. We will revisit BGP routing, DNS, and Web services.


Matthias is an assistant professor of computer science at Freie Universität Berlin, heading the Internet technologies research group.His research and teaching focus on efficient, reliable, and secure Internet communication. This includes the design and evaluation of networking protocols and architectures as well as Internet measurements and analysis. Matthias is actively involved in the IETF since 2005 andco-founded multiple successful open source projects such as RIOT, the friendly operating system for the Internet of Things, and RTRlib, a library for BGP origin validation. He is also a member of the Advisory Board of BCIX, the Berlin Commercial Internet Exchange e.V.

session chair: Roland van Rijswijk-Deij

Download the slides for Doina’s talk here.


Many networks are hiding in plain sight: words are connected into discourse, books are connected via the readers they have in common, concepts are connected into knowledge graphs, biological species into food webs, and stars into constellations. All these networks are intangible, but measuring and analysing them provides insight about how the mind and societies work. This talk runs through Network Science (a creative and very cross-disciplinary field), and demonstrates recent research, with diverse data sources, methods (from various areas of artificial intelligence), and case studies.


Doina Bucur (/’dɔɪ nɑ ‘bu kur/) is Assistant Professor of Network Data Science at University of Twente, The Netherlands. Her research revolves around the data science of networked systems. She designs computational methods to predict how a networked system will evolve in time, methods to learn the relationship between network structure and network function, and optimization algorithms to improve the functioning of such systems. Most of these algorithms build on machine learning and artificial intelligence. She works with small and big data from many domains: social, information, geographic, ecological networks, and also with communication networks. Before coming to The Netherlands, she got a PhD from the University of Aarhus, Denmark, and did postdoctoral research at the University of Oxford, UK.

09:30 – 10:30   Keynote (Vaibhav Bajpai, CISPA Helmholtz Centre for Information Security)
session chair: Roland van Rijswijk-Deij


Towards Digital Sovereignty in the Age of Hyper-giants

The Internet was initially designed to be a decentralized system, but in recent decades has transitioned towards an increasingly centralized ecosystem where majority of the Internet traffic is brokered through large content-delivery hyper-giants. In the first half of my talk, I will present a long-term perspective on the growth and ubiquity of hyper-giants, and their push towards providing new services traditionally delivered by Internet service providers (ISPs). Consequently, more content is getting centralised, and is leading to increased security and privacy concerns. In the second half
of my talk, I will speak about how we can combat this centralisation trend, and instead pivot towards digital sovereignty. I will present how new foundations can be built and deployed using upcoming secure and privacy enhancing protocols to give back users control of their data when using traditional network services, and eventually the Web.



Dr. Vaibhav Bajpai is an independent research group leader at CISPA Helmholtz Center for Information Security, Hannover. Previously, he was a senior researcher at the Department of Computer Science at the Technical University of Munich. He received his PhD (2016) and Masters (2012) degrees from Jacobs University Bremen. He is the recipient of the best of CCR award (2019), ACM SIGCOMM best paper award (2018), and IEEE CNOM best dissertation award (2017). He is also the recipient of the Preis für die beste Lehre (2020) awarded by the Department of Computer Science at TUM. His current research focuses on improving Internet operations (e.g., performance, security, and privacy) using data-intensive methods and by building real-world systems and models.

13:30 – 14:30   Keynote (Alessandro Finamore, Huawei Technologies France) – Taming the data divide to enable AI-driven networks
session chair: Anna Sperotto


Artificial Intelligence (AI) is more and more penetrating networks design and operation. Yet, if/what we need to and how/where to integrate AI in networks is still largely a debate, arguably due to the fundamental need for effective sharing of data and measurements. In this talk we review the challenges surrounding this renewed “data divide” and discuss possible ways to mitigate them.



Alessandro Finamore is a Principal Engineer at the DataCom Lab of the Paris Research Center focusing on
integrating Artificial Intelligence technologies in network monitoring and operation.
He received his Ph.D. from the Politecnico di Torino in 2012. He then joined Telefonica Research in Barcelona in 2014, working on mobile network analytics related to RAN and end-users experience. In 2018 he moved to O2/UK to lead the development of a product focusing on predicting customer satisfaction based on network data combining ML and BigData frameworks.
