Abstract: A message processing method, apparatus, and system, where the method includes sending, by a Dynamic Host Configuration Protocol for Internet Protocol version 6 (DHCPv6) client apparatus, a first message requesting assignment of an Internet Protocol version 6 (IPv6) address to a DHCPv6 server, where the first message includes a first random identifier identifying the DHCPv6 client apparatus, receiving a first reply message from the DHCPv6 server, sending a second message to the DHCPv6 server, where the second message includes a second random identifier generated using a preset algorithm and the first random identifier and identifies the DHCPv6 client apparatus, and receiving a second reply message from the DHCPv6 server. Therefore, a problem that privacy is easy to monitor or steal in an interaction process between the DHCPv6 client apparatus and the DHCPv6 server is resolved.

Abstract: An IP data packet sending method and a label switching router are disclosed. The IP data packet sending method includes: receiving a first IP data packet sent by a user by using a user equipment; allocating a first label and a second label to the first IP data packet, where the first label is used to identify a destination address of the first IP data packet, the second label is used to identify semantic information corresponding to the first IP data packet, and the semantic information is different from the destination address; encapsulating the first label and the second label into an outer layer of the first IP data packet to form a second IP data packet, where the second label is an outer label, and the first label is an inner label; and sending the second IP data packet according to the first label and the second label.
