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.

Claim (Index 20):
The packet backpressure detection device according to  claim 11 , wherein the processor is configured to:\n when each packet in a packet queue in a first direction of the PCIe port becomes a packet that is to be transmitted next in the second buffer at the PCIe port, store, in the first buffer, the packet that needs to be sent in the first direction, wherein the first direction is an upstream direction or a downstream direction of the PCIe port; and when each packet in a packet queue in a second direction of the PCIe port becomes a packet that is to be transmitted next in the second buffer at the PCIe port, store, in a third buffer, the packet that needs to be sent in the second direction, wherein the second direction is opposite to the first direction, the packet stored in the third buffer is removed from the third buffer after being sent by using the PCIe port, and the third buffer stores a maximum of one packet at any moment; record, storage duration of each packet stored in the third buffer, and accumulate the recorded storage duration of each packet stored in the third buffer; removing the packet from the third buffer after the packet is transmitted via the PCIe port; and when the second accumulated storage duration reaches the sixth value, generating a second indication of packet pressure at the PCIe port based on the second accumulated storage duration.
