Large messages may be nondestination specific; that is, they may be broadcast messages. To broadcast a multipacket message, a node first transmits a Broadcast Announce Message (BAM). This message, which must be transmitted to the global destination address, constitutes a large message warning to the nodes on the network. The BAM message contains the Parameter Group Number of the large message to be broadcast, its size, and the number of packets into which it has been packeted. Nodes interested in the data are then required to allocate the resources necessary to receive and reassemble the message. The Data Transfer PGN (PGN = 60160) is then used to send the associated data.
