Abstract
We describe a scalable server-array based testbed for simulating various usage scenarios of peer-to-peer (P2P) overlay networks. Each server is responsible for a subset of the simulated peer processes, managed by the mechanisms presented herein. The system follows a star topology, where one master server acts as a point of control for a set of slave servers. We present both the structure of the system and the activities needed before, during, and after a simulation run in order to accomplish automated simulations, where each interesting combination of the variable parameters of the overlay network is evaluated. The functionality of the control scripts is explained in detail. Among other things, the system sets up the required start conditions for a P2P overlay simulation, manages the online-time and the specific P2P activities of each simulated peer, and facilitates the handling of the generated log files, from which the result statistics are derived.
