BACnet/IP - Some basic design criteria...

The most basic consideration is that BACnet/IP devices should behave conceptually like all other BACnet devices in terms of their network activities:

Similarly, routers on B/IP networks should respond to the same network layer messages and perform the same functions as current routers. The implications of these assumptions will hopefully become clear as you work through these slides.

Here are two fundamental assumptions about BACnet devices that we make use of:

BACnet/IP uses the User Datagram Protocol (UDP), a connectionless protocol. Here is why UDP was chosen:

In the course of this presentation we will show that UDP provides all the power required to construct BACnet/IP internetworks of nearly any architecture.
