Abstract: A packet backpressure detection method and apparatus are provided. The method includes: a device which having a Peripheral Component Interconnect Express (PCIe) port storing a plurality of packets for transmission in a packet queue and storing a packet that is to be transmitted next in a first buffer, where the queue comprises a plurality of packets that are to be transmitted via the PCIe port; and the queue is stored in a second buffer; recording a storage duration of each packet stored in the first buffer, and accumulating the storage duration of each packet stored in the first buffer; removing the packet from the first buffer after the packet is transmitted via the PCIe port; and generating an indication of packet pressure at the PCIe port based on the accumulated storage duration.
