Embodiments of the present invention provide a transmission path and a data processing method for a transmission path, which are used to control a volume of data stored in the transmission path, so as to control blocking latency for a packet and avoid a case of an excessively high transmit latency for the packet. The transmission path includes: an FD storage module, configured to receive and store an FD, sent by a traffic management TM module, of the first frame, where the FD of the first frame includes a length value of the first frame; a calculating module, configured to determine, according to the 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. |
