= 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://www.tm.uka.de/itm/index.php?lang=en 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. '''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]'''. = News = November 3, 2010 * Released [OverSimDownload OverSim-20101103]. * Support for the [https://i72projekte.tm.uka.de/trac/ReaSE 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 [/chrome/site/doc/ChangeLog doc/ChangeLog]) [OldNews [Old News...]] {{{ #!html
