Abstract
BACnet(Building Automation and Control networks) is a standard data communication network protocol designed specifically for building automation and control systems. BACnet provides BACnet/IP Protocol for data communication through the Internet. BACnet device uses BBMD(BACnet Broadcasting Management Device) to deliver BACnet broadcast messages. In this study, we propose a fault tolerant BBMD in the BACnet/IP protocol. The fault tolerant BBMD improves the connectivity of BACnet/IP networks by inheriting the operation of original BBMD in the networks. The fault tolerant BBMD is implemented with added functions to the original BACnet/IP protocol so that it can provide backward compatibility with the original BACnet/IP devices. We examined the validity of the fault tolerant BBMD using an experimental model.
