Data transmission control method and customer premises equipment

The invention provides a data transmission control method and customer premises equipment, and relates to the technical field of data transmission. The method comprises the following steps: performing event monitoring on a target communication link corresponding to a target link tracking entry in a completion state in a preset link table by a hardware forwarding control program of a processing module; the completion state is used for indicating that the target communication link is established; if the hardware forwarding control program monitors that the transmission quantity of the data packet on the target communication link is greater than or equal to a preset transmission limit value, the hardware forwarding control program adds a hardware forwarding entry of the target communication link in a hardware forwarding module; and the hardware forwarding module forwards the data packet on the target communication link by adopting a hardware address conversion mode based on the hardware forwarding entry.
