+
+@section overview Overview
+
+BNEP is a network encapsulation protocol for bluetooth, intended to present a
+bluetooth network as an ethernet network.  Due to the bluetooth protocols, any
+network with more than two devices needs to be a star configuration, with one
+node taking on packet forwarding and routing roles.
+
+@subsection roles Roles
+
+To represent this layout, BNEP defines three roles for a node in the network.
+-# <b>PANU</b>\n
+   A PANU is the leaf node in a PAN network.  It can connect to one other
+   device, which can be operating in any of the three roles.  Some devices
+   will allow incoming connections to a PANU, although it may be that GN is
+   considered the minimum for incoming connections.
+   
+-# <b>GN</b>\n
+   A GN is the basic bridging node.  It can support up to seven attached
+   devices due to the limitations imposed by the need to stay within a
+   bluetooth piconet.  In order to support more than one PANU the GN must be
+   the piconet master.
+   
+-# <b>NAP</b>\n
+   A special GN with access to an external network (typically the internet).
+   The device may either bridge at the network level, or route IP packets
+   through Network Address Translation.
