-At the moment, we support the well-known <a href="http://www.nsnam.org/"><b>ns-3</b></a> packet-level simulator. Earlier
-releases of SimGrid did support the <b>GTNetS</b> simulator. Its support could possibly be revived by someone who would
-need it.
+This binding is still somehow limited: you can only express what is at
+the intersection between ns-3 and SimGrid. For example, ns-3 wireless
+models are not available, while no route longuer than 1 must appear in
+your SimGrid platform (add routers on need).
