The Overlay Framework

OverSim is an open-source overlay and peer-to-peer network simulation framework for the ​OMNeT++ simulation environment. The simulator contains several models for structured (e.g. Chord, Kademlia, Pastry) and unstructured (e.g. GIA) P2P systems and overlay protocols.

OverSim was developed at the ​Institute of Telematics (research group Prof. Zitterbart), Karlsruhe Institute of Technology (KIT) within the scope of the ​ScaleNet project funded by the ​German Federal Ministry of Education and Research. The simulator is actively developed and open to contributions. If you have any questions regarding OverSim, please send an email to the MailingList.
