Abstract: This application provides an address processing method and a network device. The method includes: obtaining, by a first network device, an address; determining, by the first network device, a length of a valid address of the address, where the valid address of the address is a 1st bit, whose bit value is 1, of the address to a last bit of the address; and adding, by the first network device when the length of the valid address of the address is less than a table width of a target table, S zeros before the valid address of the address to obtain an adjusted address, and processing the adjusted address based on the adjusted address and the target table, where S is a difference between the table width of the target table and the length of the valid address of the address.

Abstract: This application provides wireless communications configuration methods and apparatuses. One method includes: receiving, by a service node of a server, a first packet sent by a client device, wherein a destination address of the first packet is an internet protocol (IP) address of the server; sending, by the service node, a second packet to the client device, wherein the second packet comprises the IP address of the service node; and receiving, by the service node, a third packet sent by the client device, wherein a destination address of the third packet is the IP address of the service node that is different from the destination address of the first packet.

Abstract: This application discloses a communication method and a related device. The communication method includes: A first in-domain device determines an address length, where the “in-domain” refers to being in a local area network. Then, the first in-domain device receives a data packet, and extracts an address from the data packet based on the address length. Further, the first in-domain device forwards the data packet based on the address.

Abstract: This application provides a route information processing method, a communication apparatus, and a communication network, applied to the communication technology field. The route information processing method is used on a target node in a first network. The first network is addressed based on a tree first topology structure, and an address of a child node in the first topology structure includes an address of a parent node. Therefore, a node in the first network may calculate a route based on a destination address. When a topology structure of the first network is updated from the first topology structure to a second topology structure, and a connection relationship of a first node changes, the target node in the first network may add route information destined for the first node, so that the target node can still correctly address the first node and a descendant node of the first node.
