- * An AS is a network container, in charge of routing information between elements (hosts) and to the nearby ASes.
- * In SimGrid, there is a hierarchy of ASes, ie a tree with a unique root AS, that you can retrieve from the
- * s4u::Engine.
+ * A netzone is a network container, in charge of routing information between elements (hosts and sub-netzones)
+ * and to the nearby netzones. In SimGrid, there is a hierarchy of netzones, ie a tree with a unique root
+ * NetZone, that you can retrieve with simgrid::s4u::Engine::netRoot().
*
* The purpose of the kernel::routing module is to retrieve the routing path between two points in a time- and
- * space-efficient manner. This is done by AsImpl::getGlobalRoute(), called when creating a communication to
+ * space-efficient manner. This is done by NetZoneImpl::getGlobalRoute(), called 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 on the
- * behalf of the network.
+ * The network model could recompute the latency by itself from the list, but it would require an additional
+ * traversal of the link set. This operation being on the critical path of SimGrid, the routing computes the
+ * latency on the behalf of the network while constructing the link set.
*
- * Finding the path between two nodes is rather complex because we navigate a hierarchy of ASes, each of them
- * being a full network. In addition, the routing can declare shortcuts (called bypasses), either within an AS
- * at the route level or directly between ASes. Also, each AS can use a differing routing algorithm, depending
- * on its class. @ref{AsFull} have a full matrix giving explicitly the path between any pair of their
- * contained nodes, while @ref{AsDijkstra} or @ref{AsFloyd} rely on a shortest path algorithm. @ref{AsVivaldi}
