communication, can also borrow public telecommunications network to achieve. This makes the presentation layer, the session layer, and the transport layer in the OSI model unnecessary in the BACnet system. At the same time, the BACnet system supports a variety of networking methods in the physical layer and data link layer. BACnet can use different LAN technolog

IP subnet addressing All Hosts must support subnet addressing (rfc950 [mogulandpostel1985]). IThe P address is simply composed of a network number and a host number. Instead, the host number is divided into a sub-network number and a host number.The reason for this is that Class A and Class B addresses allocate too much space for the master host number, and the number of hosts can be-2 and 21 respectively.6-2. In fact, there are not so many hosts in a
