Abstract: 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.

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 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 a packet processing method and apparatus, to avoid chain impact of an abnormal packet caused by an abnormal underlying latency on an uncertain target flow. The method includes: receiving, by a first device, a first packet sent by a second device, where the first packet carries a first label, and the first label is determined based on a cycle in which the second device sends the first packet; determining, by the first device based on the first label, whether the first packet is a normal packet; if determining that the first packet is a normal packet, determining, by the first device, a second packet based on the first packet, where the second packet carries a second label; and sending, by the first device, the second packet to a third device in a first cycle, where the second label is determined based on the first cycle.
