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.

Communication method and related device

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 1bit, 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.

Address processing method and network device

A method for implementing network virtualization, and a related apparatus and a communications system are provided. The method for implementing network virtualization may include: receiving, by an SDN controller, a virtual network creation request that carries virtual network topology information; creating a virtual network in response to the virtual network creation request; establishing, by the SDN controller, a device mapping relationship; establishing, by the SDN controller, a port mapping relationship; allocating, by the SDN controller, a virtual SDN controller to the virtual network; and registering, by the SDN controller, a first virtual forwarding device and a second virtual forwarding device with the virtual SDN controller. Technical solutions of embodiments of the present invention help to improve networking flexibility, reduce service costs, and shorten a service deployment period.

Method for implementing network virtualization and related apparatus and communications system

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.

Packet sending method, network device, and computer-readable storage medium

The method includes: receiving, by a first forwarding device, a first control packet sent by a control device, where the first control packet carries N pieces of control information and N network slice identifiers, the N pieces of control information are in a one-to-one correspondence with the N network slice identifiers, where i&#x2208;[1, N], and N&#x2265;1; determining, by the first forwarding device, M pieces of first control information from the N pieces of control information based on the N network slice identifiers, where the M pieces of first control information are in a one-to-one correspondence with M first network slices, and the M first network slices are borne on the first forwarding device, where M&#x2265;1; and controlling, by the first forwarding device, a first network slice j based on first control information j, where j&#x2208;[1, M]. This application can reduce processing burden of the control device.
