1. A system, comprising:
a single network controller (SNC), configured to perform a centralized control function; an ingress network element, configured to perform matching on a data flow processing rule; and a function node network (FNN), configured to perform a user plane function, wherein the FNN comprises a function node (FN); wherein both the ingress network element and the FN are communicatively connected to the SNC, and a plurality of FNs are connected to each other directly or through an Internet Protocol IP network; wherein the SNC is configured to perform signaling processing to implement a control plane function of the system, and control and manage work of the ingress network element and the FN in a manner of delivering a data flow processing rule to the ingress network element or the FN; wherein the ingress network element is configured to perform matching between a data packet and the data flow processing rule, and to mark a successfully matched data packet in a label form, so that the FN acquires, according to the label, instruction information of a data operation that needs to be performed; and wherein the FN is configured to acquire, according to the label, the instruction information of the data operation that needs to be performed, and to perform data processing, data forwarding, or both, according to the instruction information. |
