Personal Information

I studied computer science at Universitaet Paderborn in Germany and received my degree in 1990. After that I continued my studies at Carnegie Mellon University, where I earned my M.Sc. in 1991 and, four years later, my Ph.D. The next four years I did postdoctoral work at AT&T Labs Research, before holding research positions at Saarland University and the Technical University Munich. Since 2006, I have been professor of Internet Network Architectures at Telekom Innovation Laboratories at Technische Universitaet Berlin. In May 2012, I was elected the first woman on the employer side of the Supervisory Board of SAP. Since the beginning of 2018 I am director at the Max Planck Institute for Informatics in Saarbruecken.

Abstract
Reproducibility is one of the key characteristics of good science, but hard to achieve for experimental disciplines like Internet measurements and networked systems. This guide provides advice to researchers, particularly those new to the field, on designing experiments so that their work is more likely to be reproducible and to serve as a foundation for follow-on work by others.

Abstract
The conventional wisdom is that a software-defined network (SDN) operates under the premise that the logically centralized control plane has an accurate representation of the actual data plane state. Nevertheless, bugs, misconfigurations, faults or attacks can introduce inconsistencies that undermine correct operation. Previous work in this area, however, lacks a holistic methodology to tackle this problem and thus, addresses only certain parts of the problem. Yet, the consistency of the overall system is only as good as its least consistent part. Motivated by an analogy of network consistency checking with program testing, we propose to add active probe-based network state fuzzing to our consistency check repertoire. Hereby, our system, PAZZ, combines production traffic with active probes to continuously test if the actual forwarding path and decision elements (on the data plane) correspond to the expected ones (on the control plane). Our insight is that active traffic covers the inconsistency cases beyond the ones identified by passive traffic. PAZZ prototype was built and evaluated on topologies of varying scale and complexity. Our results show that PAZZ requires minimal network resources to detect persistent data plane faults through fuzzing and localize them quickly.
