+<!-- Describe a dogbone graph, with 4 hosts:
+  -
+  -  S1 ___[ 1 ]___                 ___[ 3 ]___ C1
+  -                \               /
+  -                 R1 __[ 2 ]__ R2
+  -                /               \
+  -  S2 ___[ 4 ]__/                 \__[ 5 ]___ C2
+  -
+  -  This platform is a valid ns-3 platform, even if it exhibits routes of length >1,
+  -  because when you only keep the routes of length 1,
+  -  you get a graph where every host can speak to any other host.
+  -
+  -  For example, S1__C1 is (l1,l2,l3) of length >1
+  -  But it's also S1__C1 = S1__R1, R1__R2, R2__C1 which are all of length 1
