+ * This function is used by the networking model to find the information it needs when starting a communication.
+ *
+ * The things are not straightforward because the platform can be routed using several routing models.
+ * Some ASes may be routed in full, others may have only some connection information and use a shortest path on top of that, and so on.
+ * Some ASes may even not have any predefined links and use only coordinate informations to compute the latency.
+ *
+ * So, the path is constructed recursively, with each traversed AS adding its information to the set.
