OverSimFeatures

 On this page we'll present some of the available and planned features of !OverSim soon.
+
+This is a list of requirements we think a modern overlay networks simulator should fulfill.
+
+ * '''Statistics''': The simulator should be able to collect
+  statistical data such as sent, received, or forwarded network traffic per
+  node, successful or unsuccessful packet delivery, and packet hop
+  count. The output needs to be in a format that is easy to
+  postprocess e.g. for generating gnuplot output.
+
+ * '''Underlying Network Modelling''': There should be a
+  flexible underlying network scheme, which on the one hand provides a
+  fully configurable network topology with realistic bandwidths,
+  packet delays, and packet losses, and on the other hand a fast and
+  simple alternative model for high simulation performance. All
+  necessary specifications should be placed as parameters in
+  configuration files in a human readable form.
+
+ * '''Scalability''': The simulator should be able to run huge
+  simulations in real-time with at least 10.000 nodes. In these cases
+  a GUI is useless and needs to be detachable for higher
+  performance.
+
+ * '''Reuse of simulation code''': The different implementations
+  of overlay protocols should be reusable for real network
+  applications, so that researchers can validate the simulator framework results by
+  comparing them to the results from real-world test networks like
+  [http://www.planet-lab.org/ PlanetLab]. Therefore, the simulation framework should
+  be able to handle and
+  assemble real network packets and to communicate with other
+  implementations of the same overlay protocol.
+
+ * '''Flexibility''': The simulator should facilitate both
+  structured and unstructured overlay network simulations.  The user
+  should be able to specify a large number of parameters.  The
+  simulator should also be able to provide node mobility and node
+  failure, as well as malicious behavior of nodes.
+
+ * '''Documentation''': For using and extending the simulator
+  with e.g. new overlay protocols, there should be a comprehensive user
+  manual. The source code and the API has to be well documented.
+
+ * '''Interactive Visualizer''': In order to validate and debug
+  new or existing overlay protocols there should be a GUI, which
+  visualizes both the topology of the
+  underlying network and the overlay topology in a customizable way.
