 :::note
 A node being in router mode will have a CW size that is a fraction of that of a normal node at the same SNR, such that it is more likely to flood first. For an explanation of what router mode does additionally, see [settings](/docs/settings/router#enabledisable-router-mode).

-### Layer 4: DSR for Multi-Hop Unicast Messaging
-
-This layer is not yet fully implemented and is currently unused. Eventually conventional [DSR](https://en.wikipedia.org/wiki/Dynamic_Source_Routing) will be used for for unicast messaging, unless transport is switched to [QMesh](https://github.com/faydr/QMesh) or [Reticulum](https://github.com/markqvist/Reticulum).
-
-Currently, we send any multi-hop unicasts as broadcasts so that we can leverage the existing flooding implementation, even when broadcasts are not required. While this is suboptimal, it is a very rare use-case, because current networks are small and are geared towards a hiking use case, which means that most nodes are withing a very small number of hops.
-
-If a node is attemptimg to broadcast a packet and receives an ACK for that packet, it can stop trying to broadcast that packet.
