Abstract
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 [1]. 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.
