+ * @brief Create a Fat-Tree zone
+ *
+ * Fat-Tree clusters are characterized by:
+ * - levels: number of levels in the cluster, e.g. 2 (the final tree will have n+1 levels)
+ * - downlinks: for each level, how many connections between elements below them, e.g. 2, 3: level 1 nodes are connected
+ * to 2 nodes in level 2, which are connected to 3 nodes below. Determines the number total of leaves in the tree.
+ * - uplinks: for each level, how nodes are connected, e.g. 1, 2
+ * - link count: for each level, number of links connecting the nodes, e.g. 1, 1
+ *
+ * The best way to understand it is looking to the doc available in: <a
+ * href="https://simgrid.org/doc/latest/Platform_examples.html#fat-tree-cluster">Fat Tree Cluster</a>
