Abstract: The present invention provides a data packet routing method and device. When a Switch receives, form an SE, a traffic flow on which service processing is performed, the Switch can determine a forwarding rule of a corresponding service chain according to the traffic flow received from the SE, and route, according to the forwarding rule, a data packet received from the SE. Compared with a case in the prior art in which an SPC needs to deliver a forwarding rule corresponding to each traffic flow to a Switch, the embodiments of the present invention adopt the technical solutions in which the SPC only needs to deliver a forwarding rule corresponding to each service chain to the Switch, thereby reducing signaling interaction between the SPC and the Switch and saving a network overhead.
