A service routing method includes parsing a received data packet to obtain a service type of the data packet; obtaining a service data routing label according to a correspondence between the service type and the service data routing label, where the service data routing label is used to identify a routing path, and the routing path is used to describe a network path for routing the data packet to a service enabler; attaching the service data routing label to the data packet; and sending the data packet to a switch. According to the service routing method provided in embodiments of the present disclosure, data traffic of a traffic classifier is reduced, and load on the traffic classifier is lightened.
