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)
