+Topology Input Readers
+----------------------
+
+The topology modules aim at reading a topology file generated by an automatic topology generator.
+ 
+The process is divided in two steps:
+
+- running a topology generator to build a topology file
+- reading the topology file and build a ns-3 simulation
+ 
+Hence, model is focused on being able to read correctly the various topology formats.
+ 
+Currently there are three models:
+
+* ``ns3::OrbisTopologyReader`` for Orbis_ 0.7 traces 
+* ``ns3::InetTopologyReader`` for Inet_ 3.0 traces 
+* ``ns3::RocketfuelTopologyReader`` for Rocketfuel_ traces 
+ 
+An helper ``ns3::TopologyReaderHelper`` is provided to assist on trivial tasks.
+ 
+A good source for topology data is also Archipelago_.
+
+The current Archipelago Measurements_, monthly updated, are stored in the CAIDA website using 
+a complete notation and triple data source, one for each working group. 
+
+A different and more compact notation reporting only the AS-relationships (a sort of more 
+Orbis-like format) is here: as-relationships_.
+
+The compact notation can be easily stripped down to a pure Orbis format, just removing
+the double relationships (the compact format use one-way links, while Orbis use two-way
+links) and pruning the 3rd parameter. Note that with the compact data Orbis can then be
+used create a rescaled version of the topology, thus being the most effective way
+(to my best knowledge) to make an internet-like topology.
+
+Examples can be found in the directory ``src/topology-read/examples/``
