     5 @section overview Overview

     6 

     7 BNEP is a network encapsulation protocol for bluetooth, intended to present a

     8 bluetooth network as an ethernet network.  Due to the bluetooth protocols, any

     9 network with more than two devices needs to be a star configuration, with one

    10 node taking on packet forwarding and routing roles.

    12 @subsection roles Roles

    13 

    14 To represent this layout, BNEP defines three roles for a node in the network.

    15 -# <b>PANU</b>\n

    16    A PANU is the leaf node in a PAN network.  It can connect to one other

    17    device, which can be operating in any of the three roles.  Some devices

    18    will allow incoming connections to a PANU, although it may be that GN is

    19    considered the minimum for incoming connections.

    20    

    21 -# <b>GN</b>\n

    22    A GN is the basic bridging node.  It can support up to seven attached

    23    devices due to the limitations imposed by the need to stay within a

    24    bluetooth piconet.  In order to support more than one PANU the GN must be

    25    the piconet master.

    26    

    27 -# <b>NAP</b>\n

    28    A special GN with access to an external network (typically the internet).

    29    The device may either bridge at the network level, or route IP packets

    30    through Network Address Translation.
