1. A data processing method for a transmission path, comprising:
receiving and storing, by the transmission path, a frame descriptor (FD), sent by a traffic management (TM) module, of a first frame, wherein the FD of the first frame comprises a length value of the first frame;
determining, by the transmission path, according to the length value of the first frame, a volume of data stored in the transmission path, wherein the volume of the data stored in the transmission path is determined as a sum of a) the length value of the first frame, and b) a volume of data stored before the FD of the first frame is stored, wherein the volume of data stored before the FD of the first frame comprises a data volume of a frame corresponding to a stored FD and a data volume of a stored frame;
determining, by the transmission path, whether the volume of the data stored in the transmission path is greater than a preset data volume threshold; and
sending, by the transmission path, a backpressure signal to the TM module when the volume of the data stored in the transmission path is greater than the preset data volume threshold, wherein the backpressure signal is used to instruct the TM module to stop sending an FD of a second frame to the transmission path.
