4 <!-- This is an example for a fat tree cluster.
5 This is taken from figure 1(b) of the paper "D-Mod-K Routing Providing on-Blocking Traffic for Shift Permutations on
6 Real Life Fat Trees" available at https://ece.technion.ac.il/wp-content/uploads/2021/01/publication_776.pdf
7 This defines a two levels fat-tree, with 4 leaf switches connected to 4 nodes each and 2 core switches connected to
8 each leaf switch by two cables -->
