18.07.2023 | Matthias Wählisch, Technische Universität Dresden


Matthias Wählisch is a full professor and holds the Chair of Distributed and Networked Systems at TU Dresden. His research includes the design and evaluation of networking protocols and architectures as well as Internet measurements and analysis. Together with his team, he aims for real-world impact based on first-class scientific results to improve the Internet, its services, and applications. This challenge was tackled several times successfully. The research results of his group helped to improve the security of the current Internet infrastructure, introduced new services, and enabled commercial products. Matthias is actively involved in the Internet Engineering Task Force (IETF) since 2005 and coordinates multiple open-source projects. Among others he co-founded RIOT, the friendly operating system for the Internet of Things, and RTRlib, a library for route origin validation. He is a member of the Advisory Boards of BCIX, the Berlin Commercial Internet Exchange e.V., and INSO, the Internet Namespace Security Observatory, which is supported by the Internet Society (ISOC) and the Internet Corporation for Assigned Names and Numbers (ICANN).

Impactful Measurement Research: Lessons from Analyzing IP Prefix Hijacks, DDoS, and Emerging Transport Protocols


In this presentation, we start from two observations. First, the Internet is the most popular (and important) communication infrastructure, and communication is key. Second, we need to consider all pieces of the Internet puzzle to create a scalable, secure, and reliable ecosystem. Then, we will take a ride and visit some of the pieces that currently need attention, including secure inter-domain routing, denial of service attacks, and QUIC. A key argument of this talk is that Internet measurements, if conducted carefully, are a relevant tool to improve the situation.
