= The P2P Simulation Framework =

!OverSim is an open-source overlay network simulation framework for the [http://www.omnetpp.org/ OMNeT++/OMNEST] simulation environment. The peer-to-peer simulator contains several models for structured (e.g. Chord, Kademlia, Pastry) and unstructured (e.g. GIA) P2P protocols.

!OverSim is developed at the [http://www.tm.uka.de/itm/index.php?lang=en Institute of Telematics (research group Prof. Zitterbart)], Universität Karlsruhe (TH) 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.

'''If you write a paper using !OverSim, please use the following citation: [http://www.tm.uka.de/itm/publications.php?bib=250&lang=en bibtex reference]'''.

January 16, 2009
  * !OverSim was successfully deployed in the [http://www.planet-lab.org/ PlanetLab] research network on about 450 nodes to provide the [http://www.p2pns.org/ peer-to-peer name service P2PNS]. The P2PNS name service is used to built a P2P SIP VoIP network without servers. There is a [http://p2pname.org/ P2P SIP demo website] which shows the current overlay status and allows to make P2PSIP test calls.
