Abstract: A method for configuring a forwarding table for user equipment, an apparatus, and a system, where an operator server receives a service access request of user equipment, establishes a correspondence for the user equipment, and sends the correspondence to an access node (AN) controller. The correspondence includes a media access control (MAC) address of the user equipment and an identifier of an operator to which the user equipment belongs. The AN controller generates a first forwarding table according to the correspondence, and sends the first forwarding table to an AN. The AN forwards, using the first forwarding table, service data of the user equipment to the operator to which the user equipment belongs.

Abstract: A packet processing method, including a network node of an access network receiving a first packet sent by a user terminal, where the first packet is used to request an Internet Protocol (IP) address from a Dynamic Host Configuration Protocol (DHCP) server and the network node obtains a second packet, where the second packet includes the first packet, information about a port, and a Media Access Control (MAC) address of the user terminal, the port is a port through which the network node receives the first packet, and the second packet is a packet except a DHCP packet. Additionally, the network node sends the second packet to a controller.

Abstract: This application provides a packet processing method, which helps resolve a problem that a network node between a user terminal and a DHCP server is relatively complex. In the method, a network node of an access network receives a first packet sent by a user terminal, where the first packet is used to request an Internet Protocol IP address from a Dynamic Host Configuration Protocol DHCP server and the network node obtains a second packet, where the second packet includes the first packet, information about a port, and a Media Access Control MAC address of the user terminal, the port is a port through which the network node receives the first packet, and the second packet is a packet except a DHCP packet. Additionally the network node sends the second packet to a controller.

Abstract: A data transmission method includes: receiving, by the PNF SDN controller, a first packet and an access loop identifier that are sent by a first network device; generating, by the PNF SDN controller, a second packet based on the access loop identifier and the first packet; and sending, by the PNF SDN controller, the second packet to the virtualized network function software-defined networking VNF SDN controller, so that the VNF SDN controller sends the second packet to a second network device, where the second packet is used to request the second network device to assign an IP address or IP address prefix to user equipment.

Abstract: This application provides a service flow configuration method. In the method, a control device receives a first DHCP packet sent by a DHCP server, where the first DHCP packet includes an IP address of a server configured to provide a configuration file, an identifier of the configuration file, and an IP address of a user-side terminal. The control device replaces, with an IP address of the control device, the IP address being in the first DHCP packet and being of the server configured to provide the configuration file, and sends the IP address of the control device to the terminal by using a second DHCP packet. The control device receives a first request packet including the identifier of the configuration file. The control device obtains, based on the identifier of the configuration file from the server configured to provide the configuration file, a configuration file corresponding to the terminal.
