@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.
