P2P systems became an interesting area since early 2000. Researchers conducted a large amount of research in some challenging areas and, to check their experiments, several implementations and simulators were created. Over time, Internet has evolved and P2P has been widely used for file sharing, but the main structured P2P overlays were progressively abandoned. However, these overlays are still taught in network engineering courses. The aim of this master thesis is to find and implement a p2p overlay over the \texttt{simctl} platform, used both for teaching and research in the network engineering department. First, it is tried to locate and test the original structured P2P overlays source codes developed by the authors of the original publications. Then, several available P2P implementations developed by researchers and users have been tested. Once the software was selected, different scenarios for \texttt{simctl} were developed. Finally, a lab session was created by using the previous scenarios.
This project intends to find and implement a p2p overlay over the simctl platform. Simctl is used both for teaching and research in the network engineering department.
