/** @defgroup DataLink The BACnet Network (DataLink) Layer
|
|
* <b>6 THE NETWORK LAYER </b><br>
|
|
* The purpose of the BACnet network layer is to provide the means by which
|
|
* messages can be relayed from one BACnet network to another, regardless of
|
|
* the BACnet data link technology in use on that network. Whereas the data
|
|
* link layer provides the capability to address messages to a single device
|
|
* or broadcast them to all devices on the local network, the network layer
|
|
* allows messages to be directed to a single remote device, broadcast on a
|
|
* remote network, or broadcast globally to all devices on all networks.
|
|
* A BACnet Device is uniquely located by a network number and a MAC address.
|
|
*
|
|
* Each client or server application must define exactly one of these
|
|
* DataLink settings, which will control which parts of the code will be built:
|
|
* - BACDL_ETHERNET -- for Clause 7 ISO 8802-3 ("Ethernet") LAN
|
|
* - BACDL_ARCNET -- for Clause 8 ARCNET LAN
|
|
* - BACDL_MSTP -- for Clause 9 MASTER-SLAVE/TOKEN PASSING (MS/TP) LAN
|
|
* - BACDL_BIP -- for ANNEX J - BACnet/IP
|
|
* - BACDL_ALL -- Unspecified for the build, so the transport can be
|
|
* chosen at runtime from among these choices.
|
|
* - Clause 10 POINT-TO-POINT (PTP) and Clause 11 EIA/CEA-709.1 ("LonTalk") LAN
|
|
* are not currently supported by this project.
|
|
*//** @defgroup DLTemplates DataLink Template Functions
|
|
* @ingroup DataLink
|
|
* Most of the functions in this group are function templates which are assigned
|
|
* to a specific DataLink network layer implementation either at compile time or
|
|
* at runtime.
