Abstract: The present invention provide a transmission path, including: an FD storage module, configured to receive and store an FD; a calculating module, configured to determine, according to a length value of the first frame stored in the FD storage module, a volume of data stored in the transmission path; a determining module, configured to determine whether the volume of the data stored in the transmission path determined by the calculating module is greater than a preset data volume threshold; and an instructing module, configured to send a backpressure signal to the TM module when the determining module determines that the volume of the data stored in the transmission path is greater than the preset data volume threshold, where the backpressure signal is used to instruct the TM module to stop sending an FD of the second frame to the transmission path.
