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.

- OverSwarm is an OverSim extension for creating and evaluating swarm intelligence based peer-to-peer network algorithms. Download it on the OverSwarm website.
November 3, 2010
- Released OverSim-20101103.
- Support for the ReaSE Internet topology generator (ReaSEUnderlay)
- TCP support for SimpleUnderlay and InetUnderlay (still experimental)
- IPv6 support for SimpleUnderlay and InetUnderlay (still experimental)
- N-Tree: New overlay protocol for virtual worlds
- Recursive routing for the Kademlia protocol
- GlobalNodeList now internally uses a better data structure (implemented in the PeerStorage class). This allows for random node access in O(1).
- Many other bugfixes and enhancements (take a look at doc/ChangeLog)
