- * @brief Probe the routing path between two points
- *
- * The networking model uses this function when creating a communication
- * to retrieve both the list of links that the create communication will use,
- * and the summed latency that these links represent.
- *
- * The network could recompute the latency by itself from the list, but it would
- * require an additional link set traversal. This operation being on the critical
- * path of SimGrid, the routing computes the latency in behalf of the network.
- *
- * Things are rather complex here because we have to find the path from ASes to ASes, and within each.
- * In addition, the different ASes may use differing 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.
- * The algorithm for that is explained in http://hal.inria.fr/hal-00650233/
- *
- * @param src Initial point of the routing path
- * @param dst Final point of the routing path
- * @param into Container into which the traversed links should be pushed
- * @param latency Accumulator in which the latencies should be added (caller must set it to 0)
