2、地址绑定和交换状态机
* address.c - This module is used to handle the address binding that occurs
in BACnet. A device id is bound to a MAC address. The normal method is using
Who-Is, and binding with the data from I-Am. This is needed for client
ality.
* tsm.c - Transaction State Machine handles resending messages if a timeout
occurs, and is needed for client ality. The transaction state machine is
used for Confirmed messages and segmentation. For confirmed messages, it
automatically (via tsm_timer_milliseconds) handles the retries and the timeout.
It uses the InvokeID as the unique key (although officially it should be the
combination of InvokeID, DeviceID, and service). So if you tried to send a
confirmed request to a device that was taken offline, you would see the retry go
out after every apdu_timeout until apdu retries had completed. Then the
transaction would self-delete (free). The stack as it is written (and most
stacks are written this way) has a limited amount of transactions, and if you
are sending alot of confirmed data, it can be a bottleneck if they are not freed
in a timely manner.

There are a dozen demonstration applications in the demo directory,
along with many demonstation objects and handlers. All the demos accept
command line options and have been tested under Win32 and Linux.
There is a makefile in the respective demo directory for Linux and
for Borland C++ compilers, and a master makefile at the root level
(Makefile=Linux, makefile.b32=Borland).
The simplest demonstration is to run demo/server/bacserv on one PC (or
virtual PC), and run the other client demonstration applications one
at time on another PC (or virtual PC). Monitor the network communcations
using Wireshark protocol analyzer, or test the BACnet server using
BACnet Visual Test Shell VTS3.
