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. |
|
11 |
|
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. |
