The Technische Universität Darmstadt has established a research team funded by the German Research Society Deutsche Forschungsgemeinschaft (DFG) for the „Improvement of the Quality of Peer-to-Peer Systems by Systematically Researching Quality Features and Their Interdependencies“ (FOR 733). In August 2009 the second phase of this project started. In the course of that the research team got two cooperative partners, University of Mannheim and RWTH Aachen University.
