-  can derive the next hop of neighbors and that of neighbors of neighbors. For others, it has no information in the beginning,
-  which results into falling back to the FloodingRouter. Upon successful delivery via flooding, it updates the next hop of the

+  Router for direct messages, which only relays if it is the next hop for a packet. The next hop is set by the current
+  relayer of a packet, which bases this on information from a previous successful delivery to the destination via flooding.
+  Namely, in the PacketHistory, we keep track of (up to 3) relayers of a packet. When the ACK is delivered back to us via a node
+  that also relayed the original packet, we use that node as next hop for the destination from then on. This makes sure that only
+  when there’s a two-way connection, we assign a next hop. Both the ReliableRouter and NextHopRouter will do retransmissions (the
+  NextHopRouter only 1 time). For the final retry, if no one actually relayed the packet, it will reset the next hop in order to
+  fall back to the FloodingRouter again. Note that thus also intermediate hops will do a single retransmission if the intended
+  next-hop didn’t relay, in order to fix changes in the middle of the route.
