+  -- This platform is a valid NS3 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
