-\subsection pf_switch I want to describe a switch but there is no switch tag !
+\subsection pf_switch How to describe a switch given that is no switch tag?
Actually we did not include switch tag, ok. But when you're trying to
simulate a switch, the only major impact it has when you're using
(as a link is not an edge by a hyperedge, you can connect more than 2
other links to it).
+\subsection pf_multicabinets How to model multi-cabinets clusters?
+
+You have several possibilities, as usual when modeling things. If your
+cabinets are homogeneous and the intercabinet network negligible for
+your study, you should just create a larger cluster with all hosts at
+the same layer.
+
+In the rare case where your hosts are not homogeneous between the
+cabinets, you can create your cluster completely manually. For that,
+create an As using the Cluster routing, and then use one
+<cabinet> for each cabinet. This cabinet tag can only be used an
+As using the Cluster routing schema, and creating
+
+Be warned that creating a cluster manually from the XML with
+<cabinet>, <backbone> and friends is rather tedious. The
+easiest way to retrieve some control of your model without diving into
+the <cluster> internals is certainly to create one separate
+<cluster> per cabinet and interconnect them together. This is
+what we did in the G5K example platform for the Graphen cluster.
