Method for Configuring Forwarding Table for User Equipment, Apparatus, and System

An operator server, comprising:

• a memory configured to store a program code;
• a receiver configured to receive a service access request of user equipment, wherein the service access request carries a Media Access Control (MAC) address of the user equipment;
• a processor coupled to the memory and the receiver and configured to establish a correspondence for the user equipment after reading the program code stored in the memory, wherein the correspondence comprises the MAC address of the user equipment and an identifier of an operator to which the user equipment belongs;
• and
• a transmitter coupled to the processor and configured to send the correspondence to an access node (AN) controller.

An access node (AN) controller, comprising:

• a memory configured to store a program code;
• a receiver configured to receive a correspondence from an operator server, wherein the correspondence comprises a Media Access Control (MAC) address of user equipment and an identifier of an operator to which the user equipment belongs;
• a processor coupled to the memory and the receiver and configured to generate a first forwarding table after reading the program code stored in the memory, wherein the first forwarding table comprises a matching field and an action field, wherein the matching field of the first forwarding table comprises the MAC address of the user equipment as a source MAC address, wherein the action field of the first forwarding table comprises output port information, and wherein the output port information comprises information about a port on an AN determined according to the identifier of the operator;
• and
• a transmitter coupled to the processor and configured to send the first forwarding table to the AN.
