Abstract: This application provides a data processing method and apparatus. The method includes: receiving, by a first VNFC a first data packet and a flow label of the first data packet that are sent by a second VNFC, where the flow label is generated by the second VNFC according to flow information of the first data packet or is received by the second VNFC from a third VNFC; and selecting, by the first VNFC according to the flow label, a first processing node configured to process the first data packet, where the first processing node is a processing node in the first VNFC. By means of the method in this application, system consumption can be reduced, and processing efficiency of a data packet can be improved.

Abstract: This embodiment provides a user packet forwarding control method and a processing node. A processing node receives a processed user packet sent by a first target value-added server (VAS), and the processing node correspondingly generates a target processing identifier according to the processed user packet, so that the processing node determines, according to the target processing identifier, that the user packet has been processed by the first target VAS. Each processing node can determine VASs that have processed the user packet, without the need to change the original user packet, thereby effectively ensuring that each VAS provides a normal value-added service to the user packet, and avoiding a fault in a process of forwarding the user packet between value-added servers.
