A P2PSIP Demonstrator Powered by OverSim

A fundamental problem in studying peer-to-peer networks is the evaluation of new protocols. This commonly involves both the simulation of the protocol in a large-scale network as well as the testing of the protocol in connection with real applications in networks like PlanetLab. To facilitate these tasks we developed the overlay simulation framework OverSim. It was designed to fulfill a number of requirements that have been partially neglected by existing simulation frameworks. In our demonstrator we show how OverSim can not only be used to simulate overlay protocols in large-scale networks, but also demonstrate its real-world capabilities by means of a P2PSIP testbed.
