The process allows a unique data link layer address to be assigned without permanently assigning the address to the node. When a node starts up, LLAP assigns the node a randomly chosen node identifier (node ID). The uniqueness of this node ID is determined by the transmission of a special packet that is addressed to the randomly chosen node ID. If the node receives a reply to this packet, the node ID is not unique. The node therefore is assigned another randomly chosen node ID and sends out another packet addressed to that node until no reply returns. If the acquiring node does not receive a reply to the first query, it makes a number of subsequent attempts. If there is still no reply after these attempts, the node ID is considered unique, and the node uses this node ID as its data link layer address.»
