This application provides a data transmission method, a PNF SDN controller, a VNF SDN controller, and a data transmission system, where the data transmission method includes: receiving, by the PNF SDN controller, a first packet and an access loop identifier that are sent by a first network device; generating, by the PNF SDN controller, a second packet based on the access loop identifier and the first packet; and sending, by the PNF SDN controller, the second packet to the virtualized network function software-defined networking VNF SDN controller, so that the VNF SDN controller sends the second packet to a second network device, where the second packet is used to request the second network device to assign an IP address or IP address prefix to user equipment, so as to reduce network device complexity.
