A method for configuring a forwarding table for user equipment, wherein the method comprises: receiving, by an operator server, a service access request of user equipment, wherein the service access request carries a Media Access Control, MAC, address of the user equipment; establishing, by the operator server, a correspondence for the user equipment, wherein the correspondence comprises the MAC address of the user equipment and an identifier of an operator to which the user equipment belongs; being characterized by that: the method further comprises: sending, by the operator server, the correspondence to an access node, AN, controller; receiving, by the AN controller, the correspondence sent by the operator server; generating, by the AN controller, a first forwarding table, wherein the first forwarding table comprises a matching field and an action field, the matching field of the first forwarding table comprises the MAC address of the user equipment that is used as a source MAC address, the action field of the first forwarding table comprises output port information, and the output port information is information about a port on an AN determined according to the identifier of the operator; and sending, by the AN controller, the first forwarding table to the AN, wherein the first forwarding table is used by the AN for forwarding a service data packet received from the user equipment. receiving, by an operator server, a service access request of user equipment, wherein the service access request carries a Media Access Control, MAC, address of the user equipment; establishing, by the operator server, a correspondence for the user equipment, wherein the correspondence comprises the MAC address of the user equipment and an identifier of an operator to which the user equipment belongs; being characterized by that: the method further comprises: sending, by the operator server, the correspondence to an access node, AN, controller; receiving, by the AN controller, the correspondence sent by the operator server; generating, by the AN controller, a first forwarding table, wherein the first forwarding table comprises a matching field and an action field, the matching field of the first forwarding table comprises the MAC address of the user equipment that is used as a source MAC address, the action field of the first forwarding table comprises output port information, and the output port information is information about a port on an AN determined according to the identifier of the operator; and sending, by the AN controller, the first forwarding table to the AN, wherein the first forwarding table is used by the AN for forwarding a service data packet received from the user equipment. sending, by the operator server, the correspondence to an access node, AN, controller; receiving, by the AN controller, the correspondence sent by the operator server; generating, by the AN controller, a first forwarding table, wherein the first forwarding table comprises a matching field and an action field, the matching field of the first forwarding table comprises the MAC address of the user equipment that is used as a source MAC address, the action field of the first forwarding table comprises output port information, and the output port information is information about a port on an AN determined according to the identifier of the operator; and sending, by the AN controller, the first forwarding table to the AN, wherein the first forwarding table is used by the AN for forwarding a service data packet received from the user equipment.
