z B-node. Nodes of this type establish their mappings through broadcasting (The
character b stands for the word broadcast). The source node obtains the IP
address of the destination node by sending the broadcast packet containing the
host name of the destination node. After receiving the broadcast packet, the
destination node returns its IP address to the source node.
z P-node. Nodes of this type establish their mappings by communicating with
NetBIOS servers (The character p stands for peer-to-peer). The source node
sends the unicast packet to the WINS server. After receiving the unicast packet,
the WINS server returns the IP address corresponding to the destination node
name to the source node.
z M-node. Nodes of this type are p-nodes mixed with broadcasting features (The
character m stands for the word mixed), that is to say, this type of nodes obtain
mappings by sending broadcast packets first. If they fail to obtain mappings, they
send unicast packets to the WINS server to obtain mappings.
z H-node. Nodes of this type are b-nodes mixed with peer-to-peer features (The
character h stands for the word hybrid), that is to say, this type of nodes obtain
mappings by sending unicast packets to WINS servers. If they fail to obtain
mappings, they send broadcast packets to obtain mappings.
