Current P2P research have a clear lack in comparability of P2P systems regarding the quality aspects. During the first three years of the DFG research group QuaP2P individual quality characteristics and bilateral interactions between quality aspects of P2P systems have been investigated. During the second phase of QuaP2P, which started in August 2009, will focus on multilateral interactions between different quality aspects of a P2P systems aiming for a P2P specific benchmarking methodology.
Under benchmarking, we mean here a test or a group of tests, designed to compare the performance of a computer system against the performance of others. The benchmarking will now evaluate the fundamental functions of P2P systems on various investigation levels in order to qualify dependencies between quality characteristics and make them if possible quantitatively comparable.
A P2P system consists of mechanisms which are intertwined with the functionality of the system. To improve and control the quality of a P2P system, adding new or modifying existing mechanisms is necessary. Therefore, our research focuses on existing and novel mechanisms for P2P systems that control the quality of P2P systems along with the above-mentioned qualities. Furthermore, in order to address the above mentioned goals, we plan in developing a benchmarking platform along with a general benchmarking methodology for P2P systems, which allows for the comparability of different P2P mechanisms in a qualitative and quantitative manner.
