SERVICE ROUTING SYSTEM, DEVICE AND METHOD

摘要

Provided are a service routing system, device and method. The system comprises: a first service stream classifier, a service path controller, h programmable switches and m service enablers, wherein there is a first interface between the first service stream classifier and the service path controller; the service path controller respectively has a second interface with 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 the embodiments of the present invention, a notification message comprising service stream classification information is generated by a first service stream classifier; a service path controller generates a first forwarding entry corresponding to i programmable switches connected with k service enablers according to the notification message; and the i programmable switches forward a data packet of a service stream respectively according to a corresponding first forwarding entry, so that the k service enablers process the data packet of the service stream according to a sequence, and the reliability of a network can be improved.
