The present invention provides a service routing system, device, and method. The system includes: a first service flow classifier, a service path controller, h programmable switches, and m service enablers, where there is a first interface between the first service flow classifier and the service path controller, there is a second interface between the service path controller and each of the h programmable switches, each service enabler of the m service enablers is connected to one of the h programmable switches, and the h programmable switches are interconnected. In embodiments of the present invention, a first service flow classifier generates a notification message that includes service flow category information, a service path controller generates, according to the notification message, a first forwarding entry corresponding to each of i programmable switches that are connected to k service enablers, and the i programmable switches each forward a data packet of a service flow according to the corresponding first forwarding entries, so that the k service enablers process the data packet of the service flow according to a sequence. In this way, network reliability can be improved. |
