Marcel Dischinger

New: [28.01.2009] Our Glasnost project is part of the recently announced Measurement Lab, an open measurement platform to enhance Internet transparency.

I am currently a fourth-year doctoral student at the Max Planck Institute for Software Systems. My advisor is Krishna Gummadi. I received my diploma in computer science from the University of Karlsruhe, Germany in 2005.

Research

My research interests span the areas of networking and distributed systems. In particular, I am interested in the measurement, analysis, and design of Internet-scale networked systems.
My recent work focuses on making the Internet more transparent to users and researchers. As part of the Glasnost project, I am building easy to use online tools, e.g., to detect whether an ISP blocks BitTorrent traffic. Furthermore, by developing novel measurement tools I was able to study Internet edge networks, such as DSL, cable, and cellular broadband networks, which configuration and characteristics were not well-studied before, at large scale.
In a related project, I work on building new testbed infrastructures to help researchers evaluate their designs in heterogeneous network environments. And I am also working on new network architectures to deliver bulk content (e.g., DVDs, online backups) over the Internet cheaply and more efficiently.
Previously, I was working in the area of mobile ad-hoc and P2P networks.

Projects

Glasnost: Bringing Transparency to the Internet [webpage] [paper]
To improve network transparency, we are building easy to use online tools, for example a tool that can detect blocking of BitTorrent traffic by ISPs.

SatelliteLab [webpage] [paper]
SatelliteLab is a new Internet testbed design that allows all sorts of end nodes to join the testbed, e.g., home machines, wireless hosts, PDAs, and cell-phones.

Characterizing Residential Broadband Networks [webpage] [paper]
This work presents the first large-scale study of residential broadband networks and shows that they differ significantly from academic networks.

Monarch [webpage] [paper]
Monarch is a tool that accurately emulates transport protocol flows from an end host under the experimenter's control to any other end host that responds to simple TCP, UDP or ICMP packet probes.
