= The Overlay Framework =

!OverSim is an open-source overlay and peer-to-peer network simulation framework for the [http://www.omnetpp.org/ 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 [http://telematics.tm.kit.edu/english/ Institute of Telematics (research group Prof. Zitterbart)], Karlsruhe Institute of Technology (KIT) within the scope of the [http://www.scalenet.de ScaleNet] project funded by the [http://www.bmbf.de/en/index.php 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.
