 '''For support of [https://i72projekte.tm.uka.de/trac/ReaSE/ ReaSE topologies] in !OverSim, you need a new ReaSE version, which will be released in a couple of days!'''
+
+
+== How to build !OverSim with ReaSE support ==
 
 1. Download and compile ReaSE (in the following we assume you have installed OMNeT++ and !OverSim to ~/sim/):

 }}}
+
+6. Copy the generated topology to the !OverSim directory:
+{{{
+  cp ~/sim/generatedTopologies/MyFirstTopology_servers.ned ~/sim/OverSim-20101103/src/underlay/reaseunderlay/topologies/MyFirstTopology/MyFirstTopology_servers.ned
+}}}
+
+7. Edit omnetpp.ini and create a new entry containing your topologie:
+{{{
+  [Config MySimulation]
+  network = oversim.underlay.reaseunderlay.topologies.MyFirstTopology.ReaSEUnderlayNetwork
+  **.TerminalConnector.channelTypes = "oversim.underlay.reaseunderlay.topologies.MyFirstTopology.host2edge"
+  **.TerminalConnector.channelTypesRx = "oversim.underlay.reaseunderlay.topologies.MyFirstTopology.edge2host"
+}}}
+
+== How to use ReaSEGUI to generate a topology for OverSim ==
+
+=== Customize settings and generate a new topology ====
+
+1. Press "Select TGM Path" on the "Topology" panel and select ~/sim/ReaSEGUI/TGM/tgm .
+
+2. Press "Save" and select a location to save your generation parameters.
+
+3. Modify or deselect "AS-Level" parameters. The following parameters can be set:
+                Nodes: Number of autonomous systems generated.
+                Transit-Node-Thresh: Minimum node degree to be a transit AS.
+                Parameter P: PFP Growing Parameter.
+                Parameter Delta: PFP Growing Parameter.
+
+4. Modify "Router-Level" parameters: The following parameters can be set:
+                Min Nodes: Minimum routers nodes per router topology.
+                Max Nodes: Maximum routers nodes per router topology.
+                Core Ratio: Percentage of core router nodes per router topology.
+                Core Cross Link Ratio: Percentage of core cross links.
+                Min Hosts per Edge: Minimum number of hosts per edge router.
+                Max Hosts per Edge: Maximum number of hosts per edge router.
+
+        IMPORTANT NOTE: In order to use the generated topology with the ReaSEUnderlay "Router-Level" option must not be deselected.
+
+        NOTE: If the minimum number of Hosts per Edge is not zero ReaSE must be installed and included in OverSim to use the topology.
+
+5. Choose name and path of the ned file by pressing "select". e.g. ~/sim/generatedTopologies/MyFirstTopology.ned
+        NOTE: The name of the ned file will also be the name of the topology.
+
+6. Select the "OverSim topology" option.
+
+7. Press "Run" in the upper right corner of the panel. Wait a few seconds while the TGM is trying multiple times to generate the topology.
+
+=== Modified bandwiths, latencies, server and router fractions ===
+
+        1. Switch to the "Server Settings" panel.
+        2. Press "Set Script Path" and select ~/sim/ReaSEGUI/UtilScripts/setServer.pl .
+        3. Press "Save" and select a location to save your parameter settings.
+        4. Modify parameters or press "Default".
+        5. Press "Run" in the upper right corner of the panel.
+
+        NOTE: The script writes the modified topology to a new file. e.g. ~/sim/generatedTopologies/MyFirstTopology_servers.ned
