A service chain forwarding control method, which is applied to a first service function forwarder, SFF, wherein the first SFF is an SFF controlled by a local controller; and the method comprises: acquiring first service function, SF, information and second SF information, and generating a first forwarding table entry according to the first SF information and the second SF information; and performing service chain forwarding control on the first SFF according to the first forwarding table entry, wherein the first SF information is used for indicating the information of an SF attached to the first SFF, and the second SF information is used for indicating the information of an SF attached to a second SFF; and the second SFF is an SFF controlled by a software defined network, SDN, controller; wherein the step of acquiring the first service function, SF, information and the second SF information further comprises: acquiring service chain configuration information sent by the SDN controller, so as to acquire the first SF information according to the service chain configuration information, wherein the service chain configuration information is generated by the SDN controller according to preset service chain orchestration information; wherein the step of acquiring the service chain configuration information sent by the SDN controller comprises: establishing a management connection between the SDN controller and the first SFF, so as to acquire the service chain configuration information issued by the SDN controller; or, establishing a routing neighbor between the SDN controller and the first SFF, so as to acquire, by means of the routing protocol, the service chain configuration information issued by the SDN controller; or, establishing a routing neighbor between the SDN controller and the routing reflector, and establishing a routing neighbor between the first SFF and the routing reflector, so as to acquire, by means of the routing protocol, the service chain configuration information issued by the SDN controller. acquiring first service function, SF, information and second SF information, and generating a first forwarding table entry according to the first SF information and the second SF information;
